After being sick for 3 days, a client with a history of diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should evaluate which diagnostic test results to prevent arrhythmias?
Serum potassium level
The nurse should monitor the client's potassium level because during periods of acidosis, potassium leaves the cell, causing hyperkalemia. As blood glucose levels normalize with treatment, potassium reenters the cell, causing hypokalemia if levels aren't monitored closely. Hypokalemia places the client at risk for cardiac arrhythmias such as ventricular tachycardia. DKA has a lesser effect on serum calcium, sodium, and chloride levels. Changes in these levels don't typically cause cardiac arrhythmias.

A nurse educates a group of clients with diabetes mellitus on the prevention of diabetic nephropathy. Which of the following suggestions would be most important?
Control blood glucose levels.
Controlling blood glucose levels and any hypertension can prevent or delay the development of diabetic nephropathy. Drinking plenty of fluids does not prevent diabetic nephropathy. Taking antidiabetic drugs regularly may help to control blood glucose levels, but it is the control of these levels that is most important. A high-fiber diet is unrelated to the development of diabetic nephropathy.

A nurse is teaching a diabetic support group about the causes of type 1 diabetes. The teaching is determined to be effective when the group is able to attribute which of the following factors as a cause of type 1 diabetes?
Presence of autoantibodies against islet cells
Explanation: There is evidence of an autoimmune response in type 1 diabetes. This is an abnormal response in which antibodies are directed against normal tissues of the body, responding to these tissues as if they were foreign. Autoantibodies against islet cells and against endogenous (internal) insulin have been detected in people at the time of diagnosis and even several years before the development of clinical signs of type 1 diabetes.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1418
A patient with diabetes mellitus is receiving an oral antidiabetic agent. The nurse observes for which of the following symptoms when caring for this patient?
Signs of hypoglycemia
Explanation: The nurse should observe the patient receiving an oral antidiabetic agent for the signs of hypoglycemia. The time when the reaction might occur is not predictable and could be from 30 to 60 minutes to several hours after the drug is ingested. Polyuria, polydipsia, and blurred vision are the symptoms of diabetes mellitus.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1433
The diabetic client asks the nurse why shoes and socks are removed at each office visit. Which assessment finding is most significant in determining the protocol for inspection of feet?
Sensory neuropathy
Explanation: ) Neuropathy results from poor glucose control and decreased circulation to nerve tissues. Neuropathy involving sensory nerves located in the periphery can lead to lack of sensitivity, which increases the potential for soft tissue injury without client awareness. The feet are inspected on each visit to insure no injury or pressure has occurred. Autonomic neuropathy, retinopathy, and nephropathy affect nerves to organs other than feet.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1454
A nurse is assigned to care for a postoperative client with diabetes mellitus. During the assessment interview, the client reports that he's impotent and says he's concerned about the effect on his marriage. In planning this client's care, the most appropriate intervention would be to:
suggest referral to a sex counselor or other appropriate professional
.Explanation: The nurse should refer this client to a sex counselor or other professional. Making appropriate referrals is a valid part of planning the client's care. The nurse doesn't normally provide sex counseling.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1454
A client with type 1 diabetes mellitus is receiving short-acting insulin to maintain control of blood glucose levels. In providing glucometer instructions, the nurse would instruct the client to use which site for most accurate findings?
Finger
Explanation: Even though the fingertips have a higher number of nerve endings, this site provides the most accurate blood sugar reading. Alternate sites, such as upper arm, forearm, and thighs are regarded as lagging test sites and are not an option for people who require tight glucose control.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1426
A client with diabetes comes to the clinic for a follow-up visit. The nurse reviews the client’s glycosylated hemoglobin test results. Which result would indicate to the nurse that the client’s blood glucose level has been well controlled?
6.5%
Explanation: Normally, the level of glycosylated hemoglobin is less than 7%. Thus, a level of 6.5% would indicate that the client’s blood glucose level is well controlled. According to the American Diabetes Association, a glycosylated hemoglobin of 7% is equivalent to an average blood glucose level of 150 mg/dl. Thus, a level of 7.5% would indicate less control. Amount of 8% or greater indicate that control of the client’s blood glucose level has been inadequate during the previous 2 to 3 months.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1421
A nurse is providing dietary instructions to a client with hypoglycemia. To control hypoglycemic episodes, the nurse should recommend?
consuming a low-carbohydrate, high-protein diet and avoiding fasting.
Explanation: To control hypoglycemic episodes, the nurse should instruct the client to consume a low-carbohydrate, high-protein diet, avoid fasting, and avoid simple sugars. Increasing saturated fat intake and increasing vitamin supplementation wouldn't help control hypoglycemia.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1442
A client with diabetes is receiving an oral antidiabetic agent that acts to help the tissues use available insulin more efficiently. Which of the following agents would the nurse expect to administer?
Metformin
Explanation: Metformin is a biguanide and along with the thiazolidinediones (rosiglitazone and pioglitazone) are categorized as insulin sensitizers; they help tissues use available insulin more efficiently. Glyburide and glipizide which are sulfonylureas, and repaglinide, a meglitinide, are described as being insulin releasers because they stimulate the pancreas to secrete more insulin.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1434
Which instruction about insulin administration should a nurse give to a client?
" Always follow the same order when drawing the different insulins into the syringe."
Explanation: The nurse should instruct the client to always follow the same order when drawing the different insulins into the syringe. Insulin should never be shaken because the resulting froth prevents withdrawal of an accurate dose and may damage the insulin protein molecules. Insulin should never be frozen because the insulin protein molecules may be damaged. The client doesn't need to discard intermediate-acting insulin if it's cloudy; this finding is normal.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1438
A client with type 1 diabetes is scheduled to receive 30 units of 70/30 insulin. There is no 70/30 insulin available. As a substitution, the nurse may give the client:
9 units regular insulin and 21 units neutral protamine Hagedorn (NPH).
Explanation: A 70/30 insulin preparation is 70% NPH and 30% regular insulin. Therefore, a correct substitution requires mixing 21 units of NPH and 9
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1438
A patient with diabetes mellitus is receiving an oral antidiabetic agent. The nurse observes for which of the following symptoms when caring for this patient?
Hypoglycemia
Explanation: The nurse should observe the patient receiving an oral antidiabetic agent for the signs of hypoglycemia. The time when the reaction might occur is not predictable and could be from 30 to 60 minutes to several hours after the drug is ingested.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1434
A nurse explains to a client that she will administer his first insulin dose in his abdomen. How does absorption at the abdominal site compare with absorption at other sites?
Insulin is absorbed more rapidly at abdominal injection sites than at other sites
Explanation: Subcutaneous insulin is absorbed most rapidly at abdominal injection sites, more slowly at sites on the arms, and slowest at sites on the anterior thigh. Absorption after injection in the buttocks is less predictable
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1438
The nurse is educating a patient about the benefits of fruit versus fruit juice in the diabetic diet. The patient states, “What difference does it make if you drink the juice or eat the fruit? It is all the same.” What is the best response by the nurse?
“Eating the fruit instead of drinking juice decreases the glycemic index by slowing absorption.”
Explanation:Eating whole fruit instead of drinking juice decreases the glycemic index, because fiber in the fruit slows absorption
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1424
What is the only insulin that can be given intravenously?
Regular
Explanation:Insulins other than regular are in suspensions that could be harmful if administered IV.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1428
Insulin is secreted by which of the following types of cells?
Beta cells
Explanation: Insulin is secreted by the beta cells, in the islets of Langerhans of the pancreas. In diabetes, cells may stop responding to insulin, or the pancreas may decrease insulin secretion or stop insulin production completely. Melanocytes are what give the skin its pigment. Neural cells transmit impulses in the brain and spinal cord. Basal cells are a type of skin cell.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1417
A nurse is preparing to administer insulin to a child who's just been diagnosed with type 1 diabetes. When the child's mother stops the nurse in the hall, she's crying and anxious to talk about her son's condition. The nurse's best response is:
"I'm going to give your son some insulin. Then I'll be happy to talk with you."
Explanation: Attending to the mother's needs is a critical part of caring for a sick child. In this case however, administering insulin in a prompt manner supersedes the mother's needs. By informing the mother that she's going to administer the insulin and will then make time to talk with her, the nurse recognizes the mother's needs as legitimate. She provides a reasonable response while attending to the priority of administering insulin as soon as possible. Telling the mother that she can't talk with her or telling her to wait for the physician could increase the mother's fear and anxiety. The nurse shouldn't tell the mother that everything will be fine; the nurse doesn't know that everything will be fine.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1436
A client with diabetes mellitus is receiving an oral antidiabetic agent. Which of the following aspects should the nurse observe when caring for this client?
Signs of hypoglycemia
Explanation: The nurse should observe the client receiving an oral antidiabetic agent for the signs of hypoglycemia. The time when the reaction might occur is not predictable and could be from 30 to 60 minutes to several hours after the drug is ingested. Observe the client receiving an oral antidiabetic agent for signs of hypoglycemia.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1459
A nurse is caring for a diabetic patient with a diagnosis of nephropathy. What would the nurse expect the urinalysis report to indicate?
Albumin
Explanation: Albumin is one of the most important blood proteins that leak into the urine. Although small amounts may leak undetected for years, its leakage into the urine is among the earliest signs that can be detected. Clinical nephropathy eventually develops in more than 85% of people with microalbuminuria but in fewer than 5% of people without microalbuminuria (Chart 51-10). The urine should be checked annually for the presence of microalbumin.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1451
Which of the following should be included in the teaching plan for a patient receiving glargine (Lantus),"peakless" basal insulin?
Do not mix with other insulins
Explanation: Because glargine is in a suspension with a pH of 4, it cannot be mixed with other insulins because this would cause precipitation. When administering glargine (Lantus) insulin it is very important to read the label carefully and to avoid mistaking Lantus insulin for Lente insulin and vice versa. Glargine is absorbed very slowly over a 24-hour period and can be given once a day. Glargine is a "peakless" basal insulin that is absorbed very slowly over a 24-hour period.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1429
A client with type 2 diabetes asks the nurse why he can't have a pancreatic transplant. Which of the following would the nurse include as a possible reason?
Underlying problem of insulin resistance
Explanation: Clients with type 2 diabetes are not offered the option of a pancreas transplant because their problem is insulin resistance, which does not improve with a transplant. Urologic complications or the need for exocrine enzymatic drainage are not reasons for not offering pancreas transplant to clients with type 2 diabetes. Any transplant requires lifelong immunosuppressive drug therapy and is not the factor.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1417
A patient with diabetes mellitus is receiving an oral antidiabetic agent. The nurse observes for which of the following symptoms when caring for this patient?
Signs of hypoglycemia
Explanation: The nurse should observe the patient receiving an oral antidiabetic agent for the signs of hypoglycemia. The time when the reaction might occur is not predictable and could be from 30 to 60 minutes to several hours after the drug is ingested. Polyuria, polydipsia, and blurred vision are the symptoms of diabetes mellitus.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1433
Which intervention is essential when performing dressing changes on a client with a diabetic foot ulcer?
Using sterile technique during the dressing change
Explanation: The nurse should perform the dressing changes using sterile technique to prevent infection. Applying heat should be avoided in a client with diabetes mellitus because of the risk of injury. Cleaning the wound with povidone-iodine solution and debriding the wound with each dressing change prevents the development of granulation tissue, which is essential in the wound healing process. Chapter 51: Assessment and Management of Patients With Diabetes - Page 1455
An older adult patient that has diabetes type 2 comes to the emergency department with second-degree burns to the bottom of both feet and states, “I didn’t feel too hot but my feet must have been too close to the heater.” What does the nurse understand is most likely the reason for the decrease in temperature sensation?
Peripheral neuropathy
Explanation: As the neuropathy progresses, the feet become numb. In addition, a decrease in proprioception (awareness of posture and movement of the body and of position and weight of objects in relation to the body) and a decreased sensation of light touch may lead to an unsteady gait. Decreased sensations of pain and temperature place patients with neuropathy at increased risk for injury and undetected foot infections.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1453
The nurse is administering an insulin drip to a patient in ketoacidosis. What insulin does the nurse know is the only one that can be used intravenously?
Regular
Explanation: Short-acting insulins are called regular insulin (marked R on the bottle). Regular insulin is a clear solution and is usually administered 20 to 30 minutes before a meal, either alone or in combination with a longer-acting insulin. Regular insulin is the only insulin approved for IV use.

A client with status asthmaticus requires endotracheal intubation and mechanical ventilation. Twenty-four hours after intubation, the client is started on the insulin infusion protocol. The nurse must monitor the client's blood glucose levels hourly and watch for which early signs and symptoms associated with hypoglycemia?
Sweating, tremors, and tachycardia
Explanation: Sweating, tremors, and tachycardia, thirst, and anxiety are early signs of hypoglycemia. Dry skin, bradycardia, and somnolence are signs and symptoms associated with hypothyroidism. Polyuria, polydipsia, and polyphagia are signs and symptoms of diabetes mellitus
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1441
The nurse is administering lispro (Humalog) insulin. Based on the onset of action, how soon should the nurse administer the injection prior to breakfast?
10 to 15 minutes
Explanation:The onset of action of rapid-acting Humalog is within 10 to 15 minutes. It is used for rapid reduction of glucose level.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1428
A 53-year-old client is brought to the ED, via squad, where you practice nursing. He is demonstrating fast, deep, labored breathing and has a fruity odor to his breath. He has a history of type 1 diabetes. What could be the cause of his current serious condition?
Ketoacidosis
Explanation: Kussmaul respirations (fast, deep, labored breathing) are common in ketoacidosis. Acetone, which is volatile, can be detected on the breath by its characteristic fruity odor. If treatment is not initiated, the outcome of ketoacidosis is circulatory collapse, renal shutdown, and death. Ketoacidosis is more common in people with diabetes who no longer produce insulin, such as those with type 1 diabetes. The most likely cause is ketoacidosis. People with type 2 diabetes are more likely to develop hyperosmolar hyperglycemic nonketotic syndrome because with limited insulin, they can use enough glucose to prevent ketosis but not enough to maintain a normal blood glucose level. The most likely cause is ketoacidosis.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1419
A client with long-standing type 1 diabetes is admitted to the hospital with unstable angina pectoris. After the client's condition stabilizes, the nurse evaluates the diabetes management regimen. The nurse learns that the client sees the physician every 4 weeks, injects insulin after breakfast and dinner, and measures blood glucose before breakfast and at bedtime. Consequently, the nurse should formulate a nursing diagnosis of:
Deficient knowledge (treatment regimen)
Explanation: The client should inject insulin before, not after, breakfast and dinner — 30 minutes before breakfast for the a.m. dose and 30 minutes before dinner for the p.m. dose. Therefore, the client has a knowledge deficit regarding when to administer insulin. By taking insulin, measuring blood glucose levels, and seeing the physician regularly, the client has demonstrated the ability and willingness to modify his lifestyle as needed to manage the disease. This behavior eliminates the nursing diagnoses of Impaired adjustment and Defensive coping. Because the nurse, not the client, questioned the client's health practices related to diabetes management, the nursing diagnosis of Health-seeking behaviors isn't warranted.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1428
A client with diabetes comes to the clinic for a follow-up visit. The nurse reviews the client's glycosylated hemoglobin test results. Which result would indicate to the nurse that the client's blood glucose level has been well-controlled?
6.5%
Explanation: Normally the level of glycosylated hemoglobin is less than 7%. Thus a level of 6.5% would indicate that the client's blood glucose level is well-controlled. According to the American Diabetes Association, a glycosylated hemoglobin of 7% is equivalent to an average blood glucose level of 150 mg/dL. Thus, a level of 7.5% would indicate less control. Amount of 8% or greater indicate that control of the client's blood glucose level has been inadequate during the previous 2 to 3 months.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1421
A client with diabetes mellitus is receiving an oral antidiabetic agent. Which of the following aspects should the nurse observe when caring for this client?
Signs of hypoglycemia
Explanation: The nurse should observe the client receiving an oral antidiabetic agent for the signs of hypoglycemia.

A client with type 1 diabetes has a highly elevated glycosylated hemoglobin (Hb) test result. In discussing the result with the client, the nurse is most accurate in stating:
"It tells us about your sugar control for the last 3 months."
Explanation: The nurse is providing accurate information to the client when she states that the glycosylated Hb test provides an objective measure of glycemic control over a 3-month period. The test helps identify trends or practices that impair glycemic control, and it doesn't require a fasting period before blood is drawn. The nurse can't conclude that the result occurs from poor dietary management or inadequate insulin coverage.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1427
A patient with diabetes mellitus is prescribed to switch from animal to synthesized human insulin. Which of the following factors should the nurse monitor when caring for the patient?
Low blood glucose levels
Explanation: Patients who switch from animal to synthesized human insulin should be monitored for low blood glucose levels initially because the human form of insulin is used more effectively. Human insulin causes fewer allergic reactions than insulin obtained from animal sources. Polyuria and hypertonicity are the symptoms of diabetes mellitus.
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1430
A male client, aged 42, is diagnosed with diabetes mellitus. He visits the gym regularly and is a vegetarian. Which of the following factors is important when assessing the client?
The client's consumption of carbohydrates
Explanation: While assessing a client, it is important to note the client's consumption of carbohydrates because he has high blood sugar. Although other factors such as the client's mental and emotional status, history of tests involving iodine, and exercise routine can be part of data collection, they are not as important to information related to the client's to be noted in a client with high blood sugar
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1422
During a follow-up visit 3 months following a new diagnosis of type 2 diabetes, a patient reports exercising and following a reduced-calorie diet. Assessment reveals that the patient has only lost 1 pound and did not bring the glucose-monitoring record. Which of the following tests will the nurse plan to obtain?
Glycosylated hemoglobin level
Explanation: Glycosylated hemoglobin is a blood test that reflects average blood glucose levels over a period of approximately 2 to 3 months. When blood glucose levels are elevated, glucose molecules attach to hemoglobin in red blood cells. The longer the amount of glucose in the blood remains above normal, the more glucose binds to hemoglobin and the higher the glycated hemoglobin level becomes.

A nurse is teaching a patient recovering from diabetic ketoacidosis (DKA) about management of “sick days.” The patient asks the nurse why it is important to monitor the urine for ketones. Which of the following statements is the nurse’s best response?
Ketones accumulate in the blood and urine when fat breaks down. Ketones signal a deficiency of insulin that will cause the body to start to break down stored fat for energy.
Explanation: ) Ketones (or ketone bodies) are byproducts of fat breakdown, and they accumulate in the blood and urine. Ketones in the urine signal a deficiency of insulin and control of type 1 diabetes is deteriorating. When almost no effective insulin is available, the body starts to break down stored fat for energy
Chapter 51: Assessment and Management of Patients With Diabetes - Page 1427
The nurse is teaching a patient about self-administration of insulin and mixing of regular and neutral protamine Hagedorn (NPH) insulin. Which of the following is important to include in the teaching plan?
When mixing insulin, the regular insulin is drawn up into the syringe first.
Explanation: When rapid-acting or short-acting insulins are to be given simultaneously with longer-acting insulins, they are usually mixed together in the same syringe; the longer-acting insulins must be mixed thoroughly before drawing into the syringe. The American Diabetic Association (ADA) recommends that the regular insulin be drawn up first. The most important issues are (1) that patients are consistent in technique, so the wrong dose is not drawn in error or the wrong type of insulin, and (2) that patients not inject one type of insulin into the bottle containing a different type of insulin. Injecting cloudy insulin into a vial of clear insulin contaminates the entire vial of clear insulin and alters its action.

A nurse is teaching a 38-year-old man with newly diagnosed hypertension who asks if there is any harm in stopping his antihypertensive medication if he decides to discontinue it. The correct reply addresses the consequence of stopping antihypertensive medications abruptly. Which of the following statements from the nurse would be appropriate?
"Rebound hypertension can occur."
Clients need to be informed that rebound hypertension can occur if they stop antihypertensive medications suddenly. This can be extremely dangerous and have serious consequences. Hypotension would not be a problem with discontinuation of antihyperstensive medications
Chapter 31: Assessment and Management of Patients With Hypertension - Page 872
Which client statement indicates a good understanding of the nutritional modifications needed to manage hypertension?
"Limiting my salt intake to 2 grams per day will improve my blood pressure."
To lower blood pressure, a client should limit daily salt intake to 2 g or less. Alcohol intake is associated with a higher incidence of hypertension, poor compliance with treatment, and refractory hypertension. Chronic, moderate caffeine intake and fat intake don't affect blood pressure
Chapter 31: Assessment and Management of Patients With Hypertension - Page 865
The nurse is caring for an 82-year-old male client who has come to the clinic for a yearly physical. When assessing the client, the nurse notes the blood pressure (BP) is 140/93. The nurse knows that in older clients what happens that may elevate the systolic BP?
Loss of arterial elasticity
In older clients, systolic BP may be elevated because of loss of arterial elasticity (arteriosclerosis). Systolic BP would not become elevated by a decrease in blood volume, an increase in calcium intake, or a decrease in cardiac output
Chapter 31: Assessment and Management of Patients With Hypertension - Page 863
Officially, hypertension is diagnosed when the patient demonstrates a systolic blood pressure greater than ______ mm Hg and a diastolic blood pressure greater than _____ mm Hg over a sustained period.
140, 90
According to the categories of blood pressure levels established by the JNC VI, stage 1 hypertension is demonstrated by a systolic pressure of 140 to 159, or a diastolic pressure of 90 to 99. Pressure of 130 systolic and 80 diastolic falls within the normal range for an adult. Pressure of 110 systolic and 60 diastolic falls within the normal range for an adult. Pressure of 120 systolic and 70 diastolic falls within the normal range for an adult
Chapter 31: Assessment and Management of Patients With Hypertension - Page 862
Which of the following client scenarios would be correct for the nurse to identify as a client with secondary hypertension?
A client diagnosed with kidney disease
Secondary hypertension is an elevated blood pressure that results from or is secondary to some other disorder such as kidney disease, a tumor of the adrenal medulla, or atherosclerosis. Depression alone is typically not associated with hypertension. Advanced age and alcohol intake are considered factors for essential hypertension
Chapter 31: Assessment and Management of Patients With Hypertension - Page 862
It is appropriate for the nurse to recommend smoking cessation for patients with hypertension because nicotine
increases the heart rate, constricts arterioles, and reduces the heart's ability to eject blood.

Doug is 47 year old man admitted to your medical unit with an ulceration on his right foot. His blood glucose level is 473. He tells you that he takes NPH insulin 40 units every morning and Regular ( Humulin R) insulin sliding scale with each meal and at bedtime.
Doug said his doctor told him to keep his glucose between 100 and 150. What is the normal range for blood glucose? Why didn’t the doctor recommend that Doug keep his glucose in the normal range?
Why do you think this incident occurred at 4pm?
The hypoglycemia occurred at 4pm because of the combined effects of his R-insulin and N-insulin. The effect of the R-insulin He took before lunch was beginning to decline but were still relatively strong. In addition, the effect of the N-insulin taken in the morning was beginning to peak. The combination of both of these insulin effects caused the body to move too much glucose from the blood stream into body cells, which led to the hypoglycemia
When you enter his room to check his 4 p.m. vital signs, he complains of a headache, and he’s started sweating before you finish taking his vitals. Based on your nursing assessment, what do you suspect?
BS is 69
What nursing interventions should you implement?
The next day, when checking Doug’s 745am blood glucose, the results are 350. What are possible causes of Doug’s blood glucose to be so high? What interventions should you implement?
Hyperglycemia when waking up in the morning:
Dawn phenomenon: a normal glucose level until about 3am, glucose rises. Nocturnal surges of hormones creates a greater need for insulin
Change time of injection of evening intermediate insulin from dinner to bedtime
Insulin waning: progressive increase of blood glucose from bedtime to morning
Common with evening intermediate is giving before dinner; increase dinner or bedtime dose
Somogyi effect: nocturnal hypoglycemia with rebound hyperglycemia
Decrease evening dose or increase bedtime snack
Doug develops symptoms of gastroenteritis. What should you teach Doug about Sick Day Rules?
Take insulin (or oral meds as usual)
Test blood glucose and test urine ketones every 3-4 hours
May need to supplement doses of Regular every 3-4 hours
Unable to follow meal plan: substitute soft foods 6-8 times a day
Drink fluids (1/2 cup of regular soda or OJ, 1 cup of Gatorade)
DIABETES MELLITUS
A group of diseases characterized by hyperglycemia due to defects in insulin secretion, insulin action, or both
Type I
Type II
Gestational
DM associated with other conditions or syndromes
Table 51-1, page 1418
Insulin is an anabolic (storage) hormone
(FUNCTIONS OF DIABETES)
Transports and metabolizes glucose for energy
Stimulates storage of glucose in the liver and muscle as glycogen
Signals the liver to stop the release of glucose
Enhances the storage of dietary fat in adipose tissue
Accelerates transport of amino acids into cells
Inhibits the breakdown of stored glucose, protein, and fat
Insulin producing beta cells in the pancreas are destroyed by an autoimmune process
Autoimmune response in which antibodies against normal tissue
Decrease insulin production, unchecked glucose production by the liver and fasting hyperglycemia; glucose from food cannot be stored in the liver
TYPE 1 DIABETES
Decreased sensitivity to insulin (insulin resistance) and impaired beta cell function results in decreased insulin production
The receptor sites on the cells become resistant to insulin; increase amounts of insulin is needed
TYPE 2 DIABETES
Type 1: not inherited but a genetic predisposition combined with immunologic and possibly environmental (viral) factors
Type 2: family history of diabetes, obesity, race/ethnicity, age greater than 45 years, previous identified impaired fasting glucose or impaired glucose tolerance, hypertension ≥ 140/90, HDL ≤ 35 and/or triglycerides ≥ 250, history of gestational diabetes or babies over 9 pounds
RISK FACTORS OF DIABETES
Polyuria
Polydypsia
Polyphagia
Fatigue, weakness, vision changes, tingling or numbness in hands or feet, dry skin, skin lesions or wounds that are slow to heal, recurrent infections
Type 1 may have sudden weight loss, nausea, vomiting, and abdominal pain if DKA has developed
3 "P"S CLINICAL MANIFESTATIONS
Fasting blood glucose 126 mg/dL or more

Causes include too much insulin or oral hypoglycemic agents, too little food, and excessive physical activity
Often occurs before meals, skipping snacks
Manifestations
Adrenergic symptoms: sweating, tremors, tachycardia, palpitations, nervousness, hunger
Central nervous system symptoms: inability to concentrate, headache, confusion, memory lapses, slurred speech, numbness of lips and tongue, irrational or combative behavior, double vision, drowsiness
Severe hypoglycemia may cause disorientation, seizures, and loss of consciousness
HYPOGLYCEMIA
HOW TO MANAGE HYPOGLYCEMIA?
Treatment must be immediate
Give 15 g of fast-acting, concentrated carbohydrate
Conscious patient
3 or 4 glucose tablets
4–6 ounces of juice or regular soda (not diet soda)
6–10 hard candies
2–3 teaspoons of honey
Unconscious patient/cannot swallow
25-50mL of dextrose 50% in water IV
Retest blood glucose in 15 minutes, retreat if >70 mg/dL or if symptoms persist more than 10–15 minutes and testing is not possible.
Provide a snack with protein and carbohydrate unless the patient plans to eat a meal within 30–60 minutes.
Hospitalized patient

Clinical features
Hyperglycemia
Dehydration
Acidosis
Manifestations include polyuria, polydipsia, blurred vision, weakness, headache, anorexia, abdominal pain, nausea vomiting, acetone breath, hyperventilation with Kussmaul respirations, and mental status changes
Diabetic Ketoacidosis (DKA)
Blood glucose levels vary from 300–800 mg/dL
Severity of DKA is not related to blood glucose level
Ketoacidosis is reflected in low serum bicarbonate and low pH; low PCO2 reflects respiratory compensation
Ketone bodies in blood and urine
Electrolytes vary according to water loss and level of hydration
ASSESSMENT OF DKA
Rehydration with IV fluid
IV continuous infusion of regular insulin
Reverse acidosis and restore electrolyte balance
Note: rehydration leads to increased plasma volume and decreased K+, insulin enhances the movement of K+ from extracellular fluid into the cells
Monitor
Blood glucose and renal function/UO
EKG and electrolyte levels—Potassium
VS, lung assessments, signs of fluid overload
TREATMENT OF DKA
Hyperosmolality and hyperglycemia occur due to lack of effective insulin. Ketosis is minimal or absent.
Hyperglycemia causes osmotic diuresis with loss of water and electrolytes; hypernatremia, and increased osmolality occur.
Manifestations include hypotension, profound dehydration, tachycardia, and variable neurologic signs due to cerebral dehydration.
High mortality

A 52-year-old female patient is going through menopause and
asks the nurse about estrogen replacement for its cardioprotective
benefits. What is the best response by the nurse?
a) “That’s a great idea. You don’t want to have a heart
attack.”
b) “Current research determines that the replacement of
estrogen will protect a woman after she goes into menopause.”
c)
“Current evidence indicates that estrogen is ineffective as a
cardioprotectant; estrogen is actually potentially harmful and is no
longer a recommended therapy.”
d) “You need to research it and
determine what you want to do.”
“Current evidence indicates that estrogen is ineffective as a cardioprotectant; estrogen is actually potentially harmful and is no longer a recommended therapy.”
In the past hormone therapy was routinely prescribed for postmenopausal women with the belief that it would deter the onset and progression of coronary artery disease (CAD). However, based on results from the multisite, prospective, longitudinal Women’s Health Initiative study, the American Heart Association (AHA) no longer recommends the use of hormone therapy as a prevention strategy for women. In the most recently published AHA guidelines for primary prevention of CAD in women, the use of hormone therapy (estrogen) is noted to be ineffective and potentially harmful

Pulse deficit
To determine the pulse deficit, one nurse counts the heart rate through auscultation at the apex while a second nurse simultaneously palpates and counts the radial pulse for a full minute. The difference, if any, is the pulse deficit. Pulse rhythm is the pattern of the pulsations and the pauses between them. Pulse volume is described as feeling full, weak, or thready, meaning barely palpable. The pulse quality refers to its palpated volume

For both outpatients and inpatients scheduled for diagnostic
procedures of the cardiovascular system, the nurse performs a
thorough initial assessment to establish an accurate baseline data.
Which of the following data is necessary to collect if the patient
is experiencing chest pain?
a) Sound of the
apical pulses
b) Description of the pain
c) Blood
pressure in the left arm
d) Pulse rate in upper extremities
Description of the pain
If the patient is experiencing chest pain, a history of its location, frequency, and duration is necessary, as is a description of the pain, if it radiates to a particular area, what precipitates its onset, and what brings relief. The nurse weighs the patient and measures vital signs. The nurse may measure BP in both arms and compare findings. The nurse assesses apical and radial pulses, noting rate, quality, and rhythm. The nurse also checks peripheral pulses in the lower extremities

The ability of the cardiac muscle to shorten in response to an
electrical impulse is termed which of the following?
a) Repolarization
b) Diastole
c)
Depolarization
d) Contractility
Contractility
Contractility is the ability of the cardiac muscle to shorten in response to an electrical impulse.
Depolarization is the electrical activation of a cell caused by the influx of sodium into the cell while potassium exits the cell.
Repolarization is the return of the cell to the resting state, caused by reentry of potassium into the cell while sodium exits the cell.
Diastole is the period of ventricular relaxation resulting in ventricular filling

[Lovenox])?
a) Assess for clubbing of the
fingers.
b) Assess for hypokalemia.
c) Administer calcium
supplements.
d) Report any incident of bloody urine, stools, or both.
Report any incident of bloody urine, stools, or both
The client who takes an anticoagulant, such as a low-molecular-weight heparin, is routinely screened for bloody urine, stools, or both

The nurse is providing discharge education for the client
going home after a cardiac catheterization. Which of the following
would be important information to give this client?
a) Do not ambulate until the physician indicates it is
appropriate.
b) Expect bruising to appear at the site.
c)
Avoid tub baths, but shower as desired.
d) Returning to work
immediately is okay.
Avoid tub baths, but shower as desired
Guidelines for self-care after hospital discharge following a cardiac catheterization include shower as desired (no tub baths), avoid bending at the waist and lifting heavy objects, the physician will indicate when it is okay to return to work, and notify the physician right away if you have bleeding, new bruising, swelling, or pain at the puncture site

The nurse correctly identifies which of the following data as
an example of BP and HR measurements in a patient with postural
hypotension?
a) Supine: BP 130/70 mm Hg, HR 80
bpm; sitting: BP 128/70 mm Hg, HR 80 bpm; standing: BP 130/68 mm Hg,
HR 82 bpm
b) Supine: BP 114/82 mm Hg, HR 90 bpm; sitting: BP
110/76 mm Hg, HR 95 bpm; standing: BP 108/74 mm Hg, HR 98 bpm
c) Supine: BP 120/70 mm Hg, HR 70 bpm; sitting: BP 100/55 mm Hg, HR
90 bpm; standing: BP 98/52 mm Hg, HR 94 bpm
d) Supine: BP
140/78 mm Hg, HR 72 bpm; sitting: BP 145/78 mm Hg, HR 74 bpm;
standing: BP 144/78 mm Hg, HR 74 bpm
Supine: BP 120/70 mm Hg, HR 70 bpm; sitting: BP 100/55 mm Hg, HR 90 bpm; standing: BP 98/52 mm Hg, HR 94 bpm
Postural (orthostatic) hypotension is a sustained decrease of at least 20 mm Hg in systolic BP or 10 mm Hg in diastolic BP within 3 minutes of moving from a lying or sitting to a standing position.
The following is an example of BP and HR measurements in a patient with postural hypotension: supine: BP 120/70 mm Hg, HR 70 bpm;
sitting: BP 100/55 mm Hg, HR 90 bpm;
standing: BP 98/52 mm Hg, HR 94 bpm.
Normal postural responses that occur when a person moves from a lying to a standing position include (1) a HR increase of 5 to 20 bpm above the resting rate; (2) an unchanged systolic pressure, or a slight decrease of up to 10 mm Hg; and (3) a slight increase of 5 mm Hg in diastolic pressure

The nurse is caring for a client anticipating further testing
related to cardiac blood flow. Which statement, made by the client,
would lead the nurse to provide additional teaching?
a) “I had an ECG already. It provided information on my
heart rhythm.
b) “My niece thought that I would be ordered a
magnetic resonance imaging even though I have a pacemaker.”
c)
“I am able to have a nuclide study because I do not have any
allergies.”
d) “The first test I am getting is an
echocardiography. I am glad that it is not painful.”
“My niece thought that I would be ordered a magnetic resonance imaging even though I have a pacemaker.”
A magnetic resonance imaging (MRI) test is prohibited on clients with various metal devices within their body. External metal objects must be removed. All other options are correct statements not needing clarification

A patient in the ICU has a central venous pressure (CVP) line
placed. The CVP reading is 10 mm Hg. The nurse would interpret this
reading as being related to which of the following?
a) Reduction in preload
b) Left-sided heart failure
c) Hypervolemia
d) Right-sided heart failure
Right-sided heart failure
Normal CVP is 2 to 8 mm Hg.
A CVP greater that 8 mm Hg indicates hypervolemia or right-sided heart failure.
A CVP less than 2 mm Hg indicates a reduction in preload or hypovolemia

A patient recently diagnosed with pericarditis asks his nurse
to explain what area of his heart is involved. The nurse tells the
patient that the pericardium, which is inflamed, is the:
a) Heart's muscle fibers.
b) Exterior layer of the
heart.
c) Thin fibrous sac that encases the heart.
d)
Inner lining of the heart and valves.
Thin fibrous sac that encases the heart
The pericardium is a thin, fibrous sac that encases the heart. It is composed of two layers, the visceral and the parietal pericardium. The space between these two layers is filled with fluid

The client is admitted for a scheduled cardiac
catheterization. On the morning of the procedure, while assessing
the client's morning laboratory values, the nurse notes a blood urea
nitrogen (BUN) of 34 mg/dL and a creatinine of 4.2 mg/dL. The nurse
makes it a priority to notify the physician for which of the
following reasons?
a) These values show a
risk for dysrhythmias.
b) The client is at risk for renal
failure due to the contrast agent that will be given during the
procedure.
c) The client is over-hydrated, which puts him at
risk for heart failure during the procedure.
d) The client is at
risk for bleeding.
The client is at risk for renal failure due to the contrast agent that will be given during the procedure
The contrast medium must be excreted by the kidneys. If there is already a degree of renal impairment (which these laboratory values indicate), the risk for contrast agent-induced nepropathy and renal failure is high
