Study Notes
- Subjective data includes a client's perception of pain.
- Open-ended questions should not be used to keep an interview from going off course.
- Nurses should accept client's cultural differences.
- Nurses should have knowledge of their own thoughts and feelings about sensitive issues to be therapeutic with clients.
- Use very basic lay terminology for clients with a limited vocabulary.
- During a client interview regarding smoking, direct encouragement to quit is a suitable course of action.
- Nurses should use touch appropriately and in a friendly manner.
- Nurses should provide clients with information as questions arise.
- Nurses should maintain eye contact while asking standardized questions.
- To interview a 78-year-old client, the nurse should establish rapport.
- Nurses can clarify a client's statements by rephrasing the client's statements.
- During a client interview, problems and goals are identified in the working phase of the interview.
- Place the hand flat on the body surface, and use the fist of the other hand to perform blunt percussion.
- The most common percussion method is indirect percussion.
- The nurse should draw a line through an error, writing "error" and initialing.
- Nurses should avoid slang when documenting findings and direct quotes.
- Critical thinkers validate information and judgements.
Matching terms in the left column with the correct description in the right column.
- A nursing diagnosis indicates the client does not currently have a problem but is at high risk for developing it.
Essential elements of critical thinking
- Self-rate critical thinking elements to determine level, discuss improvements with peers.
- Assess lab partners' well being.
- Analyze data to draw conclusions, identify nursing diagnoses/collaborative problems.
- Discuss diagnostic reasoning pitfalls and avoidance strategies.
Alcohol Harm
- A female client with a score of 8 on the AUDIT has hazardous alcohol consumption.
Analyzing Cases
- Analyze case study data by identifying cues, drawing inferences, constructing clusters, and documenting conclusions.
- Propose nursing diagnoses, collaborative problems and referrals.
Normal variations
- List some "normal variations" that may be observed in the mental status exam of different clients from various cultures.
- Mood, feelings, expressions, and perceptions are documented as a result of the SLUMS test (Saint Louis University Mental Status).
- Orientation to time is usually lost first, and orientation to person is usually lost last.
- Nurses test abstract reasoning by asking clients to explain similarities and differences between objects.
- After using the SLUMS tool, a score of 12 indicates a referral to the primary health care provider for further evaluation.
- CAGE assessment is used to determine if further assessment is needed.
Matching

- Erikson's theory is generativity versus stagnation.

- Role play the various levels of consciousness: lethargy, obtunded, stupor, and coma.
- Nursing Interview Guide collect subjective data from the client.
Activities
- Mrs. Phillips with constant cough should consider a collaborative problem, "Risk for stress".
Activities and Critical Thinking
- Identify cue clusters and diagnostic conclusions or collaborative problems from case studies.
