Ulcers and pain.. explain duodenal vs. gastric
The principal manifestation of ulcers is an aching, burning, cramp-like, gnawing pain. The pain has a definite relationship to eating. With gastric ulcers, food may cause the pain and vomiting may relieve it. Clients with duodenal ulcers have pain with an empty stomach, and discomfort may be relieved by ingestion of food or antacids. Clients usually describe the pain as circumscribed in an area 2 to 10 cm (0.8 to 4 inches) in diameter, between the xiphoid cartilage and the umbilicus.
The primary objective of intervention for peptic ulcer is to?
provide stomach rest.Neutralize or buffer hydrochlorich acid.
Foods individuals with ulcers should avoid
coffee, alcohol, protein foods, and milk.
what are major complications that develop after pud?
Hemorrhage, perforation, and obstruction
digestion of blood in the duodenum is?
black stool.. hemorrhage tends to occur more with gastric ulcers.
vagotomy-
Vagotomy is performed to eliminate the acid-secreting stimulus to gastric cells. Truncal vagotomy is each vagus nerve is completely cut. Selective vagotomy The surgeon partially severs the nerves to preserve the hepatic and celiac branches.
3 Proximal vagotomy. Partial cutting is performed, but only the parietal cell mass is denervated; innervation of both the antrum and the pyloric sphincter is preserved.
*Cutting the vagal nerve fibers selectively avoids the problems of impaired emptying and diarrhea that follow the truncal vagotomy. It also eliminates the necessity for a drainage anastomosis to offset gastric stasis. Proximal vagotomy also reduces acid secretion and preserves the function of the antrum.
pyloplasty
facilitates emptying of stomach content
marginal ulcer
A marginal ulcer can develop where gastric acids come in contact with the operative site, either at the site of the anastomosis or in the jejunum. Ulceration may cause scarring and obstruction. Hemorrhage and perforation can also occur at the surgical site.
alkaline reflux gastritis
Alkaline reflux gastritis caused by duodenal contents occurs after gastric surgery in which the pylorus has been bypassed or removed. It also occurs after pyloroplasty and gastrojejunostomy. Usually, an associated vagotomy has been performed, which decreases gastric motility, allowing reflux of duodenal contents into the stomach.
dumping syndrome
This postprandial problem occurs after gastrojejunostomy because ingested food rapidly enters the jejunum without proper mixing and without the normal duodenal digestive processing. It usually subsides in 6 to 12 months. Early manifestations, which occur 5 to 30 minutes after eating, involve the vasomotor disturbances of vertigo, tachycardia, syncope, sweating, pallor, palpitation, diarrhea, and nausea with a desire to lie down. The client's blood pressure and pulse may either rise or fall.
dumping sydrome late manifestations occur?
Late manifestations, which occur 2 to 3 hours after eating, are a result of rapid entry of high-carbohydrate food into the jejunum, an increase in blood glucose level, and excessive insulin levels.
Management involves decreasing the amount of food taken at one time and maintaining a high-protein, high-fat, low-carbohydrate, dry diet. Gastric emptying can be delayed by eating in a recumbent or semi-recumbent position, lying down after meals, increasing the fat content in the diet, and avoiding fluids 1 hour before, with, or 2 hours after meals.The client may also be given sedatives and antispasmodic agents to delay gastric emptying. When manifestations persist, surgical intervention may include reducing the size of the gastroenterostomy or converting a Billroth II resection to a Billroth I by inserting a short segment of jejunum between the duodenal stump and the stomach.
location of duodenal ulcers-
Duodenal ulcers occur on both the anterior and posterior walls; anterior wall ulcers may produce tenderness on palpation of the abdomen. Patients generally complain of localized epigastric pain that occurs when the stomach is empty and that is relieved by food or antacids.
Anterior ulcers are more likely to perforate, whereas posterior ulcers are more likely to bleed.
True
Peptic ulcer pain is usually described as a gnawing, burning, or aching, usually in the epigastric area, and may radiate around to the back. The pain usually begins when the stomach is empty and may disappear with the ingestion of food or an antacid. Because of this, the pain often occurs at night when the stomach is empty, especially with DUs. t/f

6) Inhibition of COX-2
⪠First-generation NSAIDs (e.g., aspirin, ibuprofen) inhibit COX-1 and COX-2.
⪠Second-generation NSAIDs, also known as coxibs, produce selective inhibition of COX-2, and thereby spare COX-1.
⪠First-generation NSAIDs cannot suppress inflammation without also posing a risk of serious adverse effects (gastric ulceration, bleeding, and renal impairment).
⪠By sparing COX-1, second-generation NSAIDs can suppress inflammation while causing fewer side effects than do first-generation NSAIDs.

vericrose veins
common in clients older than 30 years of age whose occupations require prolonged standing. Varicose veins are also frequently seen in pregnant women, clients with systemic problems (e.g., heart disease), obese clients, and clients with a family history of varicose veins.
test for vericrose veins?
Trendelenburg test assists with the diagnosis. The client is placed in a supine position with elevated legs. As the client sits up, the veins would normally fill from the distal end; however, if there are varicosities, the veins fill from the proximal end.
Varicose veins are surgically removed when they are larger than?
4 mm in diameter or are in clusters. The stab avulsion technique may be used if the saphenous veins are competent. The surgeon exposes varices through 2- to 3-mm stab incisions, grasping the veins with hooks, and dividing and avulsing each vein.
postop- client needs to keep legs elevated. perform rom excercises,
Varicose veins may be either primary or secondary.
Primary varicose veins often result from a congenital or familial predisposition that leads to loss of elasticity of the vein wall. Secondary varicosities occur when trauma, obstruction, DVT, or inflammation causes damage to valves.
perthes test
The Perthes test is used to evaluate the patency of deep veins. With the patient supine and the extremity elevated, occlude the subcutaneous veins with a tourniquet just above the knee to prevent filling of superficial varicosities from above. As the patient walks, muscular tension will act on the deep veins and empty the dilated superficial varicosities. When these superficial veins fail to empty, suspect that the deep veins are also incompetent.
hypothyroidism in adults (dosing)
The dosage should be low initially and then increased gradually until full replacement doses have been achieved. A typical dosing schedule consists of 50 μg daily (PO) for 2 weeks followed by 100 μg daily for 2 additional weeks. Thereafter, daily doses of 100 to 150 μg are taken for life. When calculated on a body weight basis, the average adult dose is about 1.7 μg/kg/day.

clean catch urine specimen
(cleaning female)
Cleanse meatus with one front-to-back motion with each of three cleansing sponges.
Keep labia separated throughout procedure.
clean catch procedure
give patients a sterile urine cup, sterile disinfectant wipes, and clean gloves. The cup and disinfectant wipes are often prepackaged together. The package usually contains instructions, but instruct the patient in how to wash and how to collect the specimen. Anxiety, difficulty or inability to read, or language barriers will prevent the patient from fully comprehending the instructions independently.
Instruct female patients to use the disinfectant wipes to clean from the meatus toward the rectum. Instruct men to clean the meatus in a circular motion moving from the center of the meatus to the outside. Caution the patient against wiping repeatedly with the contaminated cloth. The patient then opens a sterile urine cup. Tell your patient to start and discard the initial stream into a toilet or bedpan. This cleans or flushes the urethral orifice and meatus of resident bacteria. During the midstream, or middle portion of voiding, collect the specimen. Immediately after obtaining the specimen, place a sterile top securely over the container and send it to the laboratory for testing.
clean catch procedure from catheter bag
Most urinary drainage systems have a self-sealing, covered specimen collection port built into the top of the drainage tubing. Clean this area, then aspirate the specimen with a sterile needle and syringe. You may need to clamp the tubing below the port for 15 to 20 minutes to allow enough urine to accumulate.
If there is no collection port and the catheter is not rubber-like silicone (Silastic), use a small 25-gauge needle and syringe to aspirate urine from the catheter itself.
Once the client is discharged from the PACU, vital signs are often measured every?
15 minutes for four times, every 30 minutes for four times, every 2 hours for four times, and then every 4 hours for 24 to 48 hours if the client's condition is stable. Thereafter, vital signs are assessed according to the facility's policy, the client's condition, and the nurse's judgment.
stridor
high pitched crowing sound
Snoring and stridor are signs of?
airway obstruction resulting from tracheal or laryngeal spasm or edema, mucus in the airway, or blockage of the airway from edema or tongue relaxation. When neuromuscular blocking agents are retained, the client has muscle weakness, which could affect gas exchange. Indicators of muscle weakness include the inability to maintain a head lift, weak hand grasps, and an abdominal breathing pattern.
A pulse deficit

A Penrose drain (a single-lumen, soft, open, latex tube) is a gravity-type drain under the dressing.
Drainage on the dressing is expected with open tube drains but is not expected with closed drainage systems. Assess closed-suction drains, such as Hemovac, VacuDrain, and Jackson-Pratt drains, for maintenance of suction. A T-tube may be placed after abdominal cholecystectomy to drain bile. Figure 22-3 shows commonly used drains. Monitor the amount, color, and type of drainage while the client is in the PACU and at least every 8 hours after the client is transferred to the medical-surgical nursing unit. Large amounts of sanguineous drainage may indicate internal bleeding.

If the wound healing is to be healed by second or third intention,
then it is left open to heal from the fascia to the skin, and special wound handling must occur. Measures can include wound packing, dressings, drains, ostomy bags, and so on, depending on wound size and location and drainage from the wound. Measure and record the amount of drainage every shift for comparison with earlier assessments to guide potential care plan changes
Thus the state of consciousness depends on successful interaction between the brainstem and cerebral hemispheres. T/F

Locked in syndrome
Locked-in syndrome is a condition in which the motor pathways in the brainstem are destroyed but the RAS and higher cognitive functions remain intact. In this state, patients are unable to move or speak because of destruction of the motor pathways that control those functions, but they are capable of interacting with their environment. The motor functions of blinking and extraocular movements are usually spared because those pathways lie above the level of the pons. Locked-in patients therefore can communicate with eye movements and are capable of full arousal and understanding.
decorticate posturing
Abnormal flexion of the arms at the elbows, wrists, and hands with concurrent extension of the legs is called decorticate posturing.

The pancreas produces four digestive enzymes:
lipase, amylase, chymotrypsin, and trypsin.
enzymes are secreted into the duodenum, where they help digest fats, carbohydrates, and proteins. To protect these enzymes from stomach acid and pepsin, the pancreas secretes bicarbonate. The bicarbonate neutralizes acid in the duodenum, and the resulting elevation in pH inactivates pepsin.
Pancreatic enzymes are available as two basic preparations: pancreatin and pancrelipase.
Pancreatin is made from hog or beef pancreas. Pancrelipase is made from hog pancreas. Pancrelipase has enzyme activity far greater than that of pancreatin. As a result, pancrelipase is the preferred preparation. Trade names for pancrelipase include Viokase, Lipram, Pancrease MT, and Pancrecarb MS.

true
This usually occurs in the predawn hours of 2:00 to 4:00 am. When the somogyi effect occurs, a rapid decrease in blood glucose during the night hours stimulates a release of hormones (e.g., cortisol, glucagon, epinephrine) to increase blood glucose by lipolysis, gluconeogenesis, and glycogenolysis. Management of the somogyi effect involves monitoring blood glucose between 2:00 am and 4:00 am and reducing the bedtime insulin dosage.

2 kinds of insulin, one syringe..
1 With an insulin syringe and needle, inject air, equal to the dose of insulin to be withdrawn, into the vial of intermediate- or long-acting (cloudy) insulin. Do not touch the tip of the needle to the solution.
2 Remove the syringe from the vial of cloudy insulin.
3 With the same syringe, inject air, equal to the dose of insulin to be withdrawn, into the vial of rapid- or short-acting insulin (clear vial). Then withdraw the correct dose into the syringe.
4 Remove the syringe from the clear insulin vial after carefully removing air bubbles in the syringe to ensure correct dose.
5 Return to the vial of intermediate- or long-acting (cloudy) insulin, and withdraw the correct dose.
6 Administer mixture of insulins within 5 minutes of preparing it. Rapid- or short-acting insulin can bind with intermediate- or long-acting insulin, thus reducing the action of the faster-acting insulin.
Alcohol ingestion may be contraindicated in people receiving chlorpropamide therapy, since alcohol use can cause an âAntabuse effect,â in which facial flushing, headaches, and dizziness occur.

hbg A1C
The level of A1C increases when individuals have prolonged hyperglycemic serum levels. Red blood cells have a life span of 4 months; therefore a measurement of A1C will give the prescriber an evaluation of the client's long-term diabetic control. An elevated A1C indicates inadequate diabetic control for the previous 2 to 3 months
insulin pump
The insulin pump is battery-operated and connected to a small computer that is programmed to release small amounts of insulin per hour (see Figure 5-8). It does not analyze the blood glucose level, but it is programmed according to the client's daily insulin needs, diet, and physical exercise. The client can also push a button that releases a bolus dose to cover each meal consumed.

sulfonylureas
The sulfonylureas enhance the release of insulin from the beta cells in the pancreas, decrease liver glycogenolysis (the breakdown of glycogen stored in the liver to glucose) and gluconeogenesis (the formation of glycogen from fatty acids and proteins rather than from carbohydrates), and increase cellular sensitivity to insulin in body tissues. Therefore they reduce the concentration of blood glucose in people with a functioning pancreas.

meperidine
the drug has a short half-life, and hence dosing must be repeated at short intervals. Second, meperidine interacts adversely with a number of drugs. Third, with continuous use, there is a risk of harm owing to accumulation of a toxic metabolite. Accordingly, routine use of the drug should be avoided. However, meperidine may still be appropriate for patients who can't take other opioids, and for patients with drug-induced rigors or post-anesthesia shivering.

oral route
ORAL
Preferred because of convenience, cost, and relatively steady blood levels
Higher dosages of oral form of opioids required for equivalent parenteral analgesia
Peak drug effect occurs after 1-2 hours for most analgesics
Delay in onset is disadvantage when rapid control of severe pain or of fluctuating pain is desired
SUBLINGUAL/BUCCAL/TRANSMUCOSAL
Tablet or liquid placed between cheek and gum (buccal) or under tongue (sublingual)
Highly desirable because more rapid onset than with oral route
Less first-pass effect through liver than oral route, which normally reduces analgesia from oral opioids (unless sublingual/buccal form swallowed, which occurs often in children)
Few drugs commercially available in this form
IV bolus
Preferred for rapid control of severe pain
Provides most rapid onset of effect, usually in about 5 minutes
Advantage for acute pain, procedural pain, and breakthrough pain
Needs to be repeated hourly for continuous pain control

Buffer the solution by adding 1 part sodium bicarbonate (1 mEq/mL) to 9 to 10 parts 1% or 2% lidocaine with or without epinephrine (see Guidelines box on p. 680)
Normal saline with preservative, benzyl alcohol (except neonates), anesthetizes venipuncture site
Use same dose as for buffered lidocaine (see Guidelines box on p. 680).
EMLA
covered by occlusive dressing or applied as anesthetic disk for 1 hour or more before procedure
Provides skin anesthesia about 15 minutes after application on nonintact skin
Gel (preferable) or liquid placed on wounds for suturing
Adrenaline must not be used on end arterioles (fingers, toes, tip of nose, penis, earlobes) because of vasoconstriction
LAT (lidocaine/adrenaline/tetracaine) or tetracaine/phenylephrine (tetraphen)
Vapocoolant
10-15 seconds before needle puncture
The most commonly prescribed opioids for intravenous PCA are morphine, hydromorphone, and fentanyl. t/f
true
Its important not to get the normal dose of fentanyl and morphine confused!
Fentanyl at a dose of 0.1 mg given intravenously is equivalent to 10 mg of morphine given intramuscularly.
why is retinal detachment serious?
Retinal detachment may occur suddenly or develop slowly. Symptoms include showers of floating spots before the eyes, flashes of light, and progressive loss of vision in one area. The so-called floaters are cells that are freed at the time of the retinal tear, casting shadows on the retina as they drift about the eye. The flashes of light are caused by vitreous traction on the retina. The area of vision loss depends entirely on the location of the detachment. If the detachment extends to include the macula, blindness results. When the detachment is extensive and occurs quickly, the patient may have the sensation that a curtain has been drawn before the eyes. No pain is associated with a detachment.
causes of retinal detachment?
The most common cause is a retinal break. Retinal breaks are an interruption in the full thickness of the retinal tissue, and they can be classified as tears or holes. Retinal holes are atrophic retinal breaks that occur spontaneously. Retinal tears can occur as the vitreous humor shrinks during aging and pulls on the retina. The retina tears when the traction force exceeds the strength of the retina. Once there is a break in the retina, liquid vitreous can enter the subretinal space between the sensory layer and the retinal pigment epithelium layer, causing a rhegmatogenous retinal detachment. Less frequently, retinal detachment can occur when abnormal membranes mechanically pull on the retina. These are called tractional detachments. A third type of retinal detachment is the secondary or exudative detachment that occurs with conditions that allow fluid to accumulate in the subretinal space (e.g., choroidal tumors, intraocular inflammation)
is retinal detachment a urgent situation?
urgent situation, and the patient is confronted suddenly with the need for surgery. The patient needs emotional support, especially during the immediate preoperative period when preparations for surgery produce additional anxiety. When the patient experiences postoperative pain, the nurse should administer prescribed pain medications and teach the patient to take the medication as necessary after being discharged. The patient may go home within a few hours of surgery or may remain in the hospital for several days, depending on the surgeon and the type of repair. Discharge planning and teaching is important, and the nurse should begin this process as early as possible because the patient may not remain hospitalized long.
Cataracts
1. Description
a. A cataract is an opacity of the lens that distorts the image projected onto the retina and that can progress to blindness.
b. Causes include the aging process (senile cataracts), inherited (congenital cataracts), and injury (traumatic cataracts); cataracts also can result from another eye disease (secondary cataracts).

ICP
Developmental Manifestations of Increased Intracranial Pressure
INFANT
⢠Poor feeding or vomiting
⢠Irritability or restlessness
⢠Lethargy
⢠Bulging fontanel
⢠High-pitched cry
⢠Increased head circumference
⢠Separation of cranial sutures
⢠Distended scalp veins
⢠Eyes deviated downward (âsetting-sunâ sign)
⢠Increased or decreased response to pain
CHILD
⢠Headache
⢠Diplopia
⢠Mood swings
⢠Slurred speech
⢠Papilledema (after 48 hours)
⢠Altered level of consciousness
⢠Nausea and vomiting, especially in the morning
visual acuity and age
With advancing age the lens of the eye becomes less flexible and less adjustable. In addition, the sclera changes shape, causing light to fall on the macula (an opaque portion of the cornea). Thus visual acuity declines with age.
Changes in the child's normal behavior pattern may be an important early sign of increased ICP t/f
true
As ICP rises, compression of the third cranial nerve occurs, resulting in pupil dilation with sluggish or absent constriction in response to light. A fixed dilated pupil is an ominous sign in an unconscious child. This suggests a herniation of the center section of the brain t/f
true
Level of consciousness should be described by the nurse using standard terminology:
Full consciousness: awake, alert, oriented, interacts with environment
Confused: lacks ability to think clearly and rapidly
Disoriented: lacks ability to recognize place or person
Lethargic: awakens easily but exhibits limited responsiveness
Obtunded: sleeps unless aroused, and once aroused has limited interaction with the environment
Stupor: requires considerable stimulation to arouse
Coma: vigorous stimulation produces no motor or verbal response
Temperature elevation may occur in children with increased ICP. t/f
true
cushing's response
Cushing's response, which consists of an increased systolic blood pressure with widening pulse pressure, bradycardia, and a change in respiratory rate and pattern, is usually apparent just before or at the time of brain stem herniation. This usually indicates an alteration in brain stem perfusion, with the body attempting to improve cerebral blood flow by increasing blood pressure. In children, Cushing's response is a late sign of increased ICP.
Cheyne-Stokes respiration
refers to a pattern of breathing characterized by increasing rate and depth and then decreasing rate and depth with a pause of variable length
Central neurogenic hyperventilation is
identified by a rapid rate despite normal arterial blood gas values. This type of breathing pattern usually indicates midbrain or pontine involvement.
Apneustic breathing
occurs when the child demonstrates prolonged inspiration and expiration. As Cushing's response occurs, the child will develop apnea.
Late signs of increased ICP include tachycardia that leads to bradycardia, apnea, systolic hypertension, widening pulse pressure, and decorticate or decerebrate posturing.
increased ICP will result in?
progressive neurological deterioration. If the infant's cranial suture lines are open, increased ICP will cause separation of the suture lines and an increase in the circumference of the head.
The first sign of a change in the level of ICP is change in level of consciousness; this may progress to a decrease in level of consciousness. t/f
true
Ipsilateral:
pupillary changes occurring on the same side as a cerebral lesion.
In ICP the infant will display what type of crying?
high pitched
Romberg's test:
measures balance. Client stands with feet together and arms at side, first with eyes open, then with eyes closed for 20 to 30 seconds.
Maintain semi-Fowler's position (15-30 degrees) to promote venous drainage and respiratory function.
* If the client with increased ICP develops hypovolemic shock, do not place client in Trendelenburg's position.
How should nurse Position patient with ICP?

is a procedure that has potential for greater independence from VA or VP shunting in children with noncommunicating hydrocephalus. In this procedure a small opening is made in the floor of the third ventricle, allowing CSF to flow freely through the previously blocked ventricle, thus bypassing the aqueduct of Sylvius. Children with SB and anatomic ventricular malformations are reportedly poor candidates for this procedure, as are children with bleeding disorders and those who have had previous radiotherapy

ICP- Describe how to check the infants head
In infants the head is measured daily at the point of largest measurementâthe occipitofrontal circumference (OFC). (See Chapter 7 for technique.) To avoid the likelihood of wide discrepancies, the point at which the measurements are taken is indicated on the head with a marking pen. Fontanels and suture lines are gently palpated for size, signs of bulging, tenseness, and separation. An infant with hydrocephalus and normal ICP will display bulging under certain circumstances such as straining or crying; therefore such accompanying behavior is noted. Irritability, lethargy, or seizure activity, as well as altered vital signs and feeding behavior, may indicate advancing pathology.
In the toddler a headache and lack of appetite are two of the earliest common signs of shunt malfunction. T/F
true
shunt and sports for child
there need be few restrictions placed on the child's activities (mainly contact sports), and the child is encouraged to live as would any other youngster of the same age and abilities.

Risks for breast cancer
The most important predictor for breast cancer is age; the risk increases as the woman ages.
Female Women account for 99% of breast cancer cases.
Age 50 or over Majority of breast cancers are found in postmenopausal women.
Family history Breast cancer in a first-degree relative, particularly when premenopausal or bilateral, increases risk. Gene mutations (BRCA-1 or BRCA-2) play a role in 5%-10% of breast cancer cases.
Personal history of breast cancer, colon cancer, endometrial cancer, ovarian cancer Personal history significantly increases risk of breast cancer, risk of cancer in other breast, and recurrence.
Early menarche (< age 12); late menopause (> age 55) A long menstrual history increases the risk of breast cancer.
First full-term pregnancy after age 30; nulliparity Prolonged exposure to unopposed estrogen increases risk for breast cancer.
Benign breast disease with atypical epithelial hyperplasia Atypical changes in breast biopsy increase the risk of breast cancer.
Obesity after menopause Fat cells store estrogen.
Exposure to ionizing radiation Radiation damages DNA (e.g., prior treatment for Hodgkin's disease).
Physical examination of the breasts by a trained health professional (CBE) every 3 years between ages 20 and 39 and annually thereafter
3 Annual screening mammography beginning at age 40

How to do BSE
Breast self-examination and patient instruction. 1, While in the shower or bath, when the skin is slippery with soap and water, exam-ine your breasts. Use the pads of your second, third, and fourth fingers to firmly press every part of the breast. While examining your left breast, use your right hand, and use your left hand to examine your right breast. Us-ing the pads of the fingers on your left hand, examine the entire breast us-ing small circular motions in a spiral or in an up-and-down motion so that the entire breast area is examined. Repeat the procedure using your right hand to examine your left breast. Repeat pattern of palpation under the arm. Check for any lump, hard knot, or thickening of the tissue. 2, Look at your breasts in a mirror. Stand with your arms at your side. 3, Raise your arms overhead and check for any changes in the shape of your breasts, dimpling of the skin, or any changes in the nipple. 4, Next, place your hands on your hips and press down firmly, tightening the pectoral mus-cles. Observe for asymmetry or changes, keeping in mind that your breasts probably do not exactly match. 5, While lying down, feel your breasts as described in step 1. When examining your right breast, place a folded towel under your right shoulder and put your right hand behind your head. Repeat the procedure while examining your left breast. Mark your calendar that you have completed your BSE; note any changes or unique characteristics you want to check with your health care
BSE should be done in?
good light and should include inspection before a mirror and careful, systematic palpation. The entire breast, axilla, and clavicle should be examined. The woman should be taught the BSE procedure by a health care provider using the woman's own hand on her breast. A gentle circular motion over wet, soapy skin is particularly useful if she is in the shower. The woman should be told what to look for, such as a lump, nipple discharge, nipple retraction, redness, pain or tenderness, dimpling of the skin, or edema. Some teaching techniques involve using silicone breast models that simulate normal and abnormal breast tissue to help women learn to identify problems. The woman should be shown the normal variations in her own breasts so that she will be able to detect changes. Finally, she should be reminded that most breast problems are not related to malignancy. At every annual physical examination the health care provider should ask the woman to demonstrate how she performs BSE.
cultural and ethical considerations of breast cancer
African American women have lower survival rates from breast cancer than white women, even when diagnosed at an early stage.
⢠African American women are diagnosed at a later stage of breast cancer than white women, but this fact alone does not account for the higher mortality rate.
⢠White women have a higher incidence of breast cancer than nonwhites.
⢠Breast cancer is the most commonly diagnosed cancer among Hispanic women.
⢠Hispanic women, especially Mexican Americans, have the lowest rate of cancer screening of any ethnic group.
⢠Hispanic women tend to have larger, more advanced tumors, which may relate to their higher mortality rate compared with white women.
⢠Hispanic women are more likely to be diagnosed at a later stage of breast cancer than white women.

Viagra use and concerns
Sildenafil (Viagra) is a prescription medication that is commonly ordered for ED, but not without concerns and cautions for the patient. This is especially true for geriatric patients, who generally have other medical conditions (e.g., renal disorders, hypertension, diabetes) and are usually taking more than one other prescribed medication.
side effects of viagra
headache, flushing, urinary tract infection, diarrhea, rash, and dizziness. Viagra should be used cautiously in patients who have cardiac disease and angina because these patients are at greater risk for complications, even more so if they are also on nitrates for their cardiovascular disease. This is especially problematic for the patient over 65 years of age who is self-medicating.
Warm or cool mist is a common therapeutic measure for symptomatic relief of respiratory discomfort. The moisture soothes inflamed membranes and is beneficial when there is hoarseness or laryngeal involvement. However, the use of steam vaporizers in the home is discouraged because of the hazards related to their use and limited evidence to support their efficacy. t/f

LTB is the most common croup syndrome. t/f
True! It affects children younger than 5 years of age, and the causative organisms are the parainfluenza virus, RSV, influenza A and B, and Mycoplasma pneumoniae. The disease is usually preceded by a URI, which gradually descends to adjacent structures. It is characterized by gradual onset of low-grade fever. Inflammation of the mucosa lining of the larynx and trachea causes a narrowing of the airway. When the airway is significantly narrowed, the child struggles to inhale air past the obstruction and into the lungs, producing the characteristic inspiratory stridor and suprasternal retractions. The classic barking or seal-like cough and acute stridor. Children with severe respiratory distress (traditionally, a respiratory rate greater than 60 breaths/min for infants) should not be given anything by mouth to prevent aspiration and decrease the work of breathing.
treat LTB
Nebulized epinephrine (racemic epinephrine) is often used in children with severe disease, stridor at rest, retractions, or difficulty breathing. The α-adrenergic effects cause mucosal vasoconstriction and subsequently decrease subglottic edema. The onset of action is rapid, and the peak effect is observed in 2 hours. Additional doses may be administered every 20 to 30 minutes in the intensive care unit or 3 to 4 hours in the regular hospital unit. The use of corticosteroids is beneficial because the antiinflammatory effects decrease subglottic edema. The onset of action is clinically detectable as early as 6 hours after administration, with continued improvement over 12 to 24 hours.
It is essential to allow children with mild croup to drink beverages they like and to encourage their parents to try whatever comforting measures work best (e.g., holding their child, rocking, singing). If the child is unable to take oral fluids, IV fluid therapy may be indicated.
Early signs of impending airway obstruction include
increased pulse and respiratory rate; substernal, suprasternal, and intercostal retractions; flaring nares; and increased restlessness
Stages of Separation
Protest:
Child is agitated, resists caregivers, cries, and is inconsolable.
Despair:
Child experiences hopelessness and becomes quiet, withdrawn, and apathetic.
Detachment:
Child becomes interested in the environment, plays, and seems to form relationships with caregivers and other children. If parents reappear, the child may ignore them.
separation anxiety is common with
infants and toddlers between 6 and 30 months
Bronchitis
Inflammation of the trachea and major bronchi is present in bronchitis. Mucus production is increased, and the mucosa is congested. Because of nonspecific leukocytic migration, purulent secretions can occur even in the absence of a bacterial infection.
Acute bronchitis is a self-limiting disease. Chronic bronchitis in children may indicate an underlying chronic respiratory dysfunction.more common during the winter months
Bronchitis is characterized by the
gradual onset of rhinitis and a cough that is initially nonproductive but may change to a loose cough with increased mucus production. Auscultation may reveal coarse and fine, moist crackles and high-pitched rhonchi (resembling the wheezing of asthma). Associated symptoms include malaise, low-grade fever, and increased mucus, which may be purulent.
Chest radiographs are usually normal. The diagnosis is based on the clinical picture.
Treatment bronchitis
Treatment is mainly symptomatic and includes rest, humidification, and increased fluid intake. Exposure to cigarette smoke should be avoided. Cough suppressants are not recommended unless the cough interferes with the child's ability to rest. Antihistamines should be avoided because of their drying effect on secretions. Antibiotics should be given only if a bacterial infection is confirmed by culture or if the clinical picture supports the diagnosis.

When the spleen enlarges, its normal filtering and sequestering capacity increases. Consequently there is often a reduction in the number of circulating blood cells. A slight to moderate enlargement of the spleen is usually asymptomatic and found during a routine examination of the abdomen.
when the spleen enlarges normal filtering and sequestering capacity?
After splenectomy, immunologic deficiencies may develop. IgM levels are reduced, and IgG and IgA values remain within normal limits. Postsplenectomy patients have a lifelong risk for infection, especially from encapsulated organisms such as pneumococcus. This risk is reduced by immunization with pneumococcal vaccine (e.g., Pneumovax).
immunologic system after splenectomy.
cause of parkinsons disease
The primary cause of PD is an imbalance in two neurotransmittersâdopamine (DA) and acetylcholine (ACh)âin the area of the brain called the basal ganglia. This imbalance is caused by failure of the nerve terminals in the substantia nigra to produce the essential neurotransmitter dopamine. This neurotransmitter acts in the basal ganglia to control movements. Destruction of the substantia nigra leads to dopamine depletion. Dopamine is an inhibitory neurotransmitter, and ACh is an excitatory neurotransmitter in this area of the brain. A correct balance between these two neurotransmitters is needed for the proper regulation of posture, muscle tone, and voluntary movement. Patients who suffer from PD have an imbalance in these neurotransmitters, usually a deficiency of dopamine in the substantia nigra areas of the brain, as mentioned previously. This dopamine deficiency can also lead to excessive ACh (cholinergic) activity due to the lack of a normal dopaminergic balancing effect.
drug therapy is aimed at increasing the levels of dopamine as long as there are functioning nerve terminals. It is also aimed at antagonizing or blocking the effects of ACh and slowing the progression of the disease.
