Subjective Data

Consist of information provided by the affected individual/patient (i.e. what patient says about their history).

Assessment

The collection of subjective and objective data about a patient’s health state.

Objective Data

Include information obtained by the health care provider through physical assessment, the patient’s record, and laboratory studies (i.e. what you observe by inspecting, percussing, palpating, and auscultating during physical exam).

Database

The totality of information available about the patient (from patient’s records and laboratory studies).

Diagnostic Reasoning

The process of analyzing health data and drawing conclusions to identify diagnoses.

What are the major components of the (hypothetico-deductive) nursing process?

1. Attending to initially available cues (pieces of information, signs, symptoms, or laboratory data).

2. Formulating diagnostic hypotheses (tentative explanations for a cue or a set of cues and can serve as a basis for further investigation).

3. Gathering data relative to the tentative hypotheses.

4. Evaluating each hypothesis with the new data collected (which leads to a final diagnosis).

What are the six phases of the nursing process?

1. Assessment (Collect data, use evidence-based assessment (EBA) techniques & document relevant data).

2. Diagnosis (Compare clinical findings with normal and abnormal variation and developmental events; Interpret data: identify clusters of clues, make hypotheses, test hypotheses, & derive diagnoses; Validate diagnoses; Document diagnoses).

3. Outcome identification (Identify expected outcomes; Individualize to the person; Culturally appropriate; Realistic and measurable; Include a timeline).

4. Planning (Establish priorities; Develop outcomes; Set timelines for outcomes; Identify interventions; Integrate EB trends and research; Document plan of care (POC)).

5. Implementation (Implement in a safe and timely manner; Use EB interventions; Collaborate with colleagues; Use community resources; Coordinate care delivery; Provide health teaching and health promotion).

6. Evaluation (Progress toward outcomes; Conduct systematic, ongoing, criterion-based evaluation; Include patient and significant others; Use ongoing assessment to revise diagnoses, outcomes, & plan; Disseminate results to patient and family).

Define Critical Thinking.

The multidimensional thinking process needed for sound diagnostic reasoning and clinical judgment.

What are the skills of critical thinking?

1. Identifying Assumptions.

2. Identifying organized and comprehensive approaches.

3. Validation.

4. Normal vs. Abnormal.

5. Making Inferences.

6. Clustering Related Cues.

7. Relevant vs. irrelevant.

8. Recognizing inconsistencies.

9. Identifying patterns.

10. Identifying missing information.

11. Promote Health.

12. Diagnosing actual and potential (risk) problems.

13. Setting priorities with >1 Diagnosis.

14. Identifying Patient (Pt.)-centered outcomes.

15. Specific Interventions.

16. Evaluating & Correcting Thinking.

17. Determining a Comprehensive Plan.

What do you do if there is more than one diagnosis, and how?

Set priorities by using the three levels of priority problems.

What are the three levels of priority?

• 1st Level: Emergent/Life-Threatening
  • (ABC’s: Airway, Breathing, Cardiac/Circulation + V [Vital Signs]).
• ​2nd Level: Requires prompt action.
• 3rd Level
  • Example: Teaching/Health Promotion
• Collaborative Problems
  • Team Approach

What are First-Level Priority problems?

These problems are emergent, life-threatening, and immediate, such as establishing an airway or supporting breathing.

What are Second-Level Priority problems?

These priority problems require prompt intervention to prevent deterioration, and may include a mental status change or acute pain.

What are Third-Level Priority problems?

These problems are important to the patient’s health, but can be addressed after more urgent problems. Examples include lack of knowledge or family coping.

What is the Biomedical Model concept of health?

The biomedical model (Western medicine) views health as the absence of disease. It focuses on collecting data on biophysical signs and symptoms and on curing disease.

What is the Holistic Health model?

The holistic health model assesses the whole person because it views the mind, body, and spirit as interdependent and functioning as a whole within the environment. Health depends on all these factors working together.

What is Evidence-Based Practice (EBP)?

Evidence-based practice is a systematic approach to practice that uses the best evidence, the clinician’s experience, and the patient’s preferences and values to make decisions about care and treatment.

What are the four types of data collecetion for the database?

1. Comprehensive (CPE)
2. Problem-Focused
3. Interval (Follow-up)
4. Emergency

What is a complete (total health) database?

A complete (or total health) database includes a complete health history and a full physical examination.

What is a focused or problem-centered database?

A focused (or problem-centered) database is used for a limited or short-term problem. It is smaller in scope and more targeted than the complete database.

What is a follow-up database?

A follow-up database evaluates the status of any identified problem at regular intervals to follow up on short-term or chronic health problems.

What is an emergency database?

An emergency database calls for rapid collection of data, which commonly occurs while performing lifesaving measures.

What is cultural assessment?

A systematic appraisal of an individual’s beliefs, values, and practices conducted for the purpose of providing culturally competent care.

What is cultural care?

Cultural care is professional health care that is culturally sensitive, appropriate, and competent. To develop cultural care, you must have knowledge of your personal heritage and the heritage of the nursing profession, the health care system, and the patient.

What are the four characteristics of culture?

1. It is learned from birth through language acquisition and socialization.
2. It is shared by all members of the same cultural group.
3. It is adapted to specific conditions related to environmental and technical factors.
4. It is dynamic and ever changing.

What is Ethnocentrism?

Viewing your way of life, beliefs, culture, etc. is the only way.

What is Acculturation?

The process of adapting to and acquiring another culutre.

What is a subculture/subcultural groups?

Within cultures, groups of people share different beliefs, values, and attitudes. Differences occur because of ethnicity, religion, education, occupation, age, and gender. They function within a large culture.

What is Assimilation?

The process by which a person develops a new cultural identity and becomes like the members of the dominant culture.

What is Biculturalism?

Dual pattern of identification and often of divided loyalty.

Cultures hold different beliefs of health and what causes of illness. What are the beliefs of Western Biomedical Theory?

Biomedical (or scientific) theory of illness causation is based on the assumption that all events in life have a cause and effect; that the human body functions more or less mechanically, that all life can be reduced or divided into smaller parts (e.g. human person = body+mind+spirit), and that all of reality can be observed and measured.

Cultures hold different beliefs of health and what causes of illness. What are the beliefs of Naturalistic or Holistic Theory?

Naturalistic (or Holistic) Theory is the perspective that believes that human life is only one aspect of nautre and a part of the general order of the cosmos. People may believe that the forces of nature must be kept in natural balance or harmony.

What is the Yin/Yang Theory?

The Yin/Yang Theory (is what Asians usually believe in) states that all organisms and objects in the universe consist of yin and yang energy forces; health is when all aspects of the person are in perfect balance.

Yin energy represents the female and negative forces: emptiness, darkness, and cold (cold foods too); Yang energy represents the male and positive forces: emitting warmth and fullness (hot foods).

Many Hispanics, Arab, Black, and Asian groups embrace the hot/cold theory of health and illness. What is the Hot/Cold Theory?

The four humors of the body (blood, phlegm, black bile, and yellow bile) regulate basic bodily functions and are described in terms of temperature, dryness, and moisture. The treatmen of disease consists of adding or subtracting cold, heat, dryness, or wetness to restore teh balance of the humors.

According to the hot/cold theory, the person is whole, not just a particular ailment; health consists of a positive state of total well-being, including phyiscal, psychological, spiritual, adn social aspects.

The third major way of explainig the causation of illness is Magicoreligious Theory. What is it?

The basic premise is that the world is seen as an arena in which supernatural forces dominate and that the fate of the world, and those in it, depends on the action of supernatural forces for good or evil. Examples: voodoo, witchcraft, faith healing, amulets, acupuncutre, herbal therapies, hypnosis, therapeutic touch and biofeedback.

Types of Cultural Assessment Tools

What is CHESS stand for?

CHESS:

• C = Culture/ethnicity, language
• H = Health Beliefs
• E = Economic/Education

The Interview: Types of Communication

1. A two-person interaction usually has two roles, what are they?

2. When exchanging information, both individuals engage in what type of communication?

3. What kind of factors can affect communication?

1. Sender and Receiver

2. Verbal and Nonverbal communication.

3. Internal and external factors.

Internal and external factors can affect communication. What are the three internal factors you bring to the interview?

Internal factors are what you bring to the interview. Three internal factors promote good communication: liking others, expressing empathy, and having the ability to listen.

Internal and external factors can affect communication. What are some external factors that can affect the interview?

External factors relate mainly to the physical setting. You can foster good communication with certain external factors, such as by ensuring privacy, preventing interruptions, creating a conducive environment, and documenting responses without interfering with the conversation.

The interview has three phases, what are they?

1. An introduction.
2. A working phase.
3. A closing.

Describe the three phases of the Interview.

• During the first phase, introduce the interview.
  • ​Introduce yourself, state your role in the agency, give reason for interview, and how long it should take.
• During the working phase, gather data.
  • Start with open-ended questions, which ask for narrative information. Then use closed questions, which ask for specific information in short, one- or two-word answers.
• During the closing, signal that the interview is ending.
  • ​Gives the patient one last chance to share concerns or express himself or herself.
  • Briefly summarize what you learned during the interview.
  • Always thank the patient for cooperating.

There are nine types of verbal responses that could be used during the Interview.

What are the five responses that involve your reactions to the facts or feelings the person has communicated? Give a brief summary of each.

• Faciliation
  • aka "General leads"
  • Responses that encourage the patient to say more or continue the story.
• Silence
  • Especially after open-ended questions.
  • aka "Thinking silence" for the patient.
• Reflection
  • ​Repeating/echoing part of the patient's words. It focuses further attention on a specific phrase and helps the person continue in their way.
  • Prompts patient to elaborate on the problem.
• Empathy ​
  • Many people have trouble expressing these feelings, perhaps becasue of confusion or embarrassment.
  • An empathic response recognizes a feeling, accepts it (puts it into words), and allows the person to express it without embarrassment.
    • An empathic response helps the patient feel accepted and can deal with the feeling openly.
    • Strengthens rapport.
• Clarification
  • ​Use when the person's word choice is ambiguous or confusing.
  • Also used to summarize the person's words, simplify the words to make them clearer, and then ask if you are on the right track.

Four Verbal Responses on Expressing Your Own Feelings

There are nine types of verbal responses that could be used during the Interview.

What are the four responses that shifts the frame of reference from the patient's perspective to yours; responses that include your own thoughts/feelings? Give a brief summary of each.

Use only when merited by the situation; if used too often, you can take over at the patient's expense.

• Confrontation
  • ​Certain action, feeling, or statement is observed and you now focus the patient's attention on it, giving honest feedback about what you see or feel.
  • Or you may confront the person when you notice parts of the story are inconsistent.
• Interpretation
  • ​Based on your inference or conclusion.
  • It links events, makes associations, or implies cause.
  • Also ascribes feelings and helps the person understand their own feelings in relation to the verbal message.
  • Person may correct it if it's the wrong inference, but it may help prompt further discussion.
• Explanation
  • ​Sharing factual and objective information.
• Summary
  • ​A final review of what you understand the perosn's information/story.
  • Condenses the facts adn presents a survey of how you preceive the health problem or need.
  • Signals that the termination of the interview is near.

1. Body Posture
2. Eye Contact
3. Gestures
4. Facial Expressions
5. Tone of Voice
6. Touch
7. Active Listening

What is the purpose of the Complete Health History (Hx)?

The purpose of the complete health history is to collect subjective data, which is what the person says about himself or herself.

By combining this subjective data with objective data from the physical examination and diagnostic tests, you create a database to make a judgment about the person’s health status.

What are the three purposes of the review of systems portion?

1. To evulate past and present health state of each body system.
2. To double-check for omission of significant data in the Present Illness section.
3. To evaluate health promotion practices.

What are the body systems that are reviewed in the Review Systems portion of the Health Hx?

[Hint: There are 23; and it generally goes from head-to-toe.]

1. General Overall Health State
2. Skin
3. Hair
4. Head
5. Eyes
6. Ears
7. Nose and Sinuses
8. Mouth and Throat
9. Neck
10. Breast
11. Axilla
12. Respiratory System
13. Cardiovascular
14. Peripheral Vascular
15. Gastrointestinal
16. Urinary System
17. Male Genital System
18. Female Gential System
19. Sexual Health
20. Musculoskeletal System
21. Neurologic System
22. Hematologic System
23. Endocrine System

In a complete Health Hx, a functional assessment is taken as well.

What does this assessment measure? And list the categories [hint: there are 13].

The Functional Assessment measures a person's self-care ability in the areas of general physical health or absence of illness.

This assessment usually includes:

1. Self-Esteem/Self-Concept
2. Acitivity/Exercise
3. Sleep/Rest
4. Nutrition/Elimination
5. Interpersonal Relationships/Resources
6. Spiritual Resources
7. Coping and Stress Managment
8. Personal Habits
9. Alcohol
10. Illicit or Street Drugs
11. Environment/Hazards
12. Intimate Partner Violence
13. Occupational Health

Why is a Complete Health Hx taken for a sick patient; a healthy patient?

• For sick patients, the health history includes a detailed, chronologic record of the health problem.
• For all patients, it is a screening tool for abnormal symptoms, health problems, and concerns. It also records the patient’s responses to health problems.

No matter what form is used to record the health history, plan to gather data in eight categories.

What are the eight categories?

1. Collect biographic data (such as the patient’s name, address, and date of birth as well as language and communication needs).
2. Note the source of the history (which is usually the patient, but may be someone else, such as a relative or interpreter).
3. Obtain the reason for seeking care, formerly known as the chief complaint (in the patient’s own words, briefly describe the reason for the visit).
4. Record the present health or history of present illness (For a well person, briefly note the general state of health. For a sick person, chronologically record the reason for seeking care).
   • When a patient reports a symptom, perform a symptom analysis.
     • A mnemonic that could be used is PQRSTU: Provocative or palliative, Quality or quantity, Region or radiation, Severity scale, Timing, and Understanding the patient’s perception of the problem.
5. Investigate past health events (such as illnesses, injuries, hospitalizations, and allergies [and their rx] as well as current medications).
6. Gather a family history to help detect health risks for the patient (to aid in this process, draw a pedigree or genogram).
7. Perform a review of systems to evaluate the past and present health of each body system, double-check for significant data, and assess health promotion practices (for each body system, assess for symptoms and health-promoting behaviors).
8. Perform a functional assessment (including activities of daily living, such as bathing dressing, toileting, eating, walking, housekeeping, shopping, cooking, and other factors).

The physical examination requires you to develop technical skills and a knowledge base to gather data. What are the skills requisite for the physical examination? [Hint: 4]

1. Inspection
2. Palpation
3. Percussion
4. Auscultation

Describe the technique of Inspection. What is it? How is it performed? etc.

• It's concentrated watching and always comes first.
  • Involves no touching.
• A careful scrutiny of the individual as a whole and then of each body system.
• Compare right and left sides of the body.

What is Palpation and in what order does it come in the physcial examination?

• Follows inspection and confirms points noted during it.
• It applies your sense of touch to assess these factors: texture, temperature, moisture, organ location and size, signs of swelling, vibration or pulsation, rigidity or spasticity, crepitation, presence of lumps or masses, and presence of tenderness or pain.

During Palpation, what part of the hands are used and for what?

• Fingertips: fine tactile discrimination.
  • Skin texture, swelling, pulsation, and determining presence of lumps.
• Grasping between fingers and thumb: detects position, shape, and consistency of an organ or mass.
• Dorsa (backs) of hands and fingers: determining temperature.
  • Because skin is thinner than palms.
• Base of fingers (metacarpophalangeal joints) or ulnar surface of hands: vibrations.

What is Percussion and why is it used?

It's tapping the person's skin with short, sharp strokes to assess underlying structures.

This technique is used to assess the location, size, and density of an organ, detect an abnormal mass, or elicit a deep tendon reflex.

Explain how is Percussion done.

• Place your interphalangeal joint firmly on the patient’s skin with the rest of your hand lifted off the skin.
• Then use the middle finger of your dominant hand (striking finger) to strike the stationary finger at a right angle.
• Deliver two short, sharp taps, using a quick wrist action.

• Duration: Very short.
• Sample Location: When no air is present; over thigh muscles, bone, or over tumor.

Describe what Ausculation is and what areas are commonly auscultated.

• It's listening to sounds made by the body, usually using a stethoscope.
• The heart, blood vessels, lungs, and abdomen are commonly auscultated areas.

What is the General Survey and what four areas does it cover?

• It's your overall impression of the patient and begins when you first encounter him or her.
• The F our areas covered are:
  1. Physical appearance
  2. Body structure
  3. Mobility
  4. Behavior
• Changes in any of these areas may indicate illness.

What are the subcategories assessed for Physical Appearance?

Includes an assessment of the person’s:

• Age

• Nutrition
• Symmetry
• Posture
• Position
• Body build (or contour).
  • In this area, obvious physical deformities are noted.

What is assessed for Mobility?

Assessment includes the person’s:

• Gait and Range of Motion.

What is assessed for Behavior?

Assessment includes the person’s:

• Facial expression
• Mood and Affect
• Speech
• Dress
• Personal hygiene.

There are various routes to measure the body’s core temperature. What are the three routes used?

• The Oral Route is accurate and convenient.
  • However, it may not be appropriate for a patient who is comatose or confused, has a wired mandible or facial dysfunction, or cannot close the mouth.
• The Rectal Route is used when other routes are not practical.
  • Disadvantages of the rectal route are patient discomfort and the time-consuming and disruptive nature of the activity.
• The Tympanic Route requires a tympanic membrane thermometer, which is a noninvasive, nontraumatic device that is quick and efficient to use.

Using the oral route, what is the normal range for body's Core Temperature?

• For a resting person, the normal temperature is: 37 degrees C (98.6 degrees F).
• The normal range is: 35.8 degrees to 37.3 degrees C (96.4 degrees to 99.1 degrees F).

When palpating a peripheral pulse, what are the three qualities that are assessed?

What is the normal pulse range for an adult at rest?

• The three qualities are: rate, rhythm, and force.
• For an adult at rest, the rate normally ranges from 60 to 100 bpm (beats per minute), but varies with age and sex.
• The pulse rhythm normally has an even, regular tempo.
• The force of the pulse shows the strength of the heart’s stroke volume.
  • Record the force on a three- or four-point scale, depending on your agency’s policy.

In an adult, what is Bradycardia and (when) is it normal?

• It's a heart rate of less than 50 bpm.
• It's normal within the well-trained athlete whose heart muscle develops along with the skeletal muscle.
  • It's stronger and more efficient; able to push out a larger stroke volume with each beat.
    • Thus requiring fewer beats per minute to maintain stable cardiac output.

In an adult, what is Tachycardia and (when) is it normal?

• It's a heart rate of over 90 bpm.
• It occurs normally with anxiety or increased exercise.
  • To match the body's demand for increased metabolism.

The rhythm of the pulse normally has an even tempo. However, what is one irregularity that is commonly found in children and young adults?

Why does it happen?

• Sinus Arrhythmia: the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing down to normal with expiration.
  • ​Inspiration momentarily causes a decreased stroke volume from the left side of the heart and to compensate, the heart rate increases.

Blood pressure (BP) is the pressure of the blood against the blood vessel walls. What are the two pressures used for the BP? Describe them.

• Systolic pressure: the maximum pressure felt on the artery during left ventricular contraction (or systole).
• Diastolic pressure: the elastic recoil (or resting) pressure the blood exerts constantly between contractions.

In a young adult, the average blood pressure is...

120/80 mmHg (millimeters of mercury)

In an adult, what is the normal systolic and diastolic (mmHg)?

• Systolic: Less than 120 mmHg.
• Diastolic: Less than 80 mmHg.

What is the systolic and diastolic (mmHg) of Prehypertension?

• Systolic: 120-139 mmHg.
• Diastolic: 80-89 mmHg.

What is the systolic and diastolic (mmHg) of Hypertension: Stage 1?

• Systolic: 140-159 mmHg.

​ Or...

• Diastolic: 90-99 mmHg.

What is the systolic and diastolic (mmHg) of Hypertension: Stage 2?

• Systolic: 160 mmHg or higher.

​Or...

• Diastolic: 100 mmHg or higher.

What are the Korotkoff's sounds for the systolic and diastolic pressures?

• I: Systolic pressure
• IV: muffling of sounds
• V: Diastolic pressure

What causes Hypotension and why?

• Acute myocardial infarction (AMI): decreases cardiac output.
• Shock: decreases cardiac output.
• Hemorrhage: decreases total blood volume.
• Vasodilation: decreases in peripheral vascular resistance.
• Addison's disease (hypofunction of adrenal glands).

When should you take an Orthostatic (or Postural) VS?

• Use when patient c/o (complains of) dizziness/syncope or suspect fluid depletion.

What is Orthostatic Hypotension?

• A drop in systolic pressure of more than 20 mmHg.
  • Or an orthostatic pulse increase of 20 bpm or more when a quick change of position (laying down, or sitting to a standing position).

What does a Pulse Oximeter measure and what is the normal adult measurement?

• Measures Pulse & Oxygen saturation
• Normal Spo2 (Adult): >97%
