DOMAIN 1: CLINICAL REASONING & EVIDENCE-BASED
PRACTICE (Questions 1–40)
1. What is diagnostic reasoning?
A. A checklist that replaces clinical judgment
B. A reflective, systematic process that evaluates each new data point against diagnostic
hypotheses
C. A method used only after diagnostic tests return
D. A process used solely for billing purposes
Answer: B
Rationale: Diagnostic reasoning is a form of critical thinking that systematically
evaluates subjective and objective data to support or refute diagnostic hypotheses. It
involves continuous reflection and questioning of one's thinking process to ensure
conclusions are based on evidence, not assumptions.
2. What is needed to make a sound clinical decision?
A. Provider experience only
B. Patient preference only
C. Evidence-based research, clinical practice guidelines, and published evidence-based
algorithms
D. Institutional protocols only
,Answer: C
Rationale: Sound clinical decisions require integration of evidence-based research,
clinical practice guidelines, and published evidence-based algorithms. These resources
provide the foundation for high-quality, patient-centered care.
3. Which of the following represents subjective data?
A. Blood pressure reading of 130/85 mmHg
B. Patient's complaint of "sharp chest pain that started 2 hours ago"
C. Laboratory result showing elevated white blood cell count
D. Tenderness noted on palpation of the abdomen
Answer: B
Rationale: Subjective data is anything the patient tells you, including the chief
complaint, history of present illness (HPI), and review of systems (ROS). Objective data is
measurable and verifiable information gathered through physical examination and
diagnostic testing.
4. Which of the following represents objective data?
A. "I have had a fever for three days"
B. "The pain is a 7 out of 10"
C. Temperature of 101.2°F and erythema noted on examination
D. "My mother had diabetes"
Answer: C
Rationale: Objective data is measurable, observable, and verifiable information
gathered through physical examination, vital signs measurement, and diagnostic testing.
Patient-reported information is always subjective.
5. What does the mnemonic "OLD CARTS" help you to assess?
A. Review of Systems
B. Past Medical History
C. History of Present Illness (HPI)
D. Family History
,Answer: C
Rationale: "OLD CARTS" (Onset, Location, Duration, Character, Aggravating factors,
Relieving factors, Timing, Severity) is a systematic approach used to gather detailed
information about the patient's chief complaint, which is a core component of the HPI.
6. What does the "C" stand for in the OLD CARTS mnemonic?
A. Cause
B. Character
C. Course
D. Complications
Answer: B
Rationale: OLD CARTS stands for: Onset, Location, Duration, Character (what does it feel
like?), Aggravating factors, Relieving factors, Timing, Severity.
7. A highly specific test is useful because:
A. It has few false negatives
B. It has few false positives, so a positive result "rules in" disease
C. It confirms the diagnosis regardless of the patient's history
D. It is highly sensitive and rules out disease
Answer: B
Rationale: The acronym "SPIN" (Specificity, Positive IN) helps remember that a highly
specific test, with few false positives, is best for confirming (ruling in) a diagnosis when
the result is positive.
8. Which statement best describes positive predictive value?
A. The proportion of truly diseased individuals among those with a positive test result
B. The proportion of healthy individuals with a negative test
C. The percentage of all people tested who have the disease
D. The likelihood that the test will be positive if the disease is present
, Answer: A
Rationale: Positive predictive value is the probability that a person who tests positive
for a disease actually has the disease. It is calculated by dividing true positives by all
positive test results and depends on disease prevalence in the population.
9. Which level of evidence provides the most comprehensive and rigorous basis for
practice guidelines?
A. Expert opinion
B. Case-control studies
C. Systematic reviews or meta-analyses of randomized trials
D. Cohort studies
Answer: C
Rationale: Level I evidence—systematic reviews or meta-analyses of randomized trials—
provides the most comprehensive and rigorous basis for practice guidelines.
10. Why is creating a prioritized differential diagnosis list important?
A. It satisfies billing requirements
B. It helps organize thinking and ensures life-threatening conditions are considered first
C. It is required by insurance companies
D. It replaces the need for diagnostic testing
Answer: B
Rationale: A prioritized differential diagnosis list helps clinicians organize their thinking
and ensures that life-threatening or most probable conditions are considered and ruled
out appropriately.
11. When choosing evidence-based guidelines, the NP should:
A. Follow the most recent guideline without question
B. Integrate the best research evidence with clinical expertise and patient values
C. Only use guidelines developed by insurance companies
D. Rely solely on personal experience
