NSG 550 Exam 1 V3 | NSG 550 Diagnostic
Reasoning for Nurse Practitioners | Wilkes
University | 2026 Q&A with Rationale
(Wilkes NSG550 Exam 1 2026)
1. Which clinical reasoning model is characterized by the practitioner forming an early
hypothesis based on initial patient data and then testing it through further inquiry?
A. Pattern Recognition
B. Algorithm-Based Assessment
C. Hypothetico-Deductive Reasoning
D. Intuitive Processing
Answer: C
Rationale: Hypothetico-Deductive reasoning involves the formulation of preliminary
hypotheses early in the encounter. The clinician then collects focused data through history
and physical examination to confirm or refute these possibilities. This is considered a gold
standard for complex diagnostic situations where simple patterns are not immediately
obvious.
2. In the context of diagnostic testing, what does the term ‘Sensitivity’ specifically refer to?
A. The proportion of people without the disease who test negative.
B. The probability that a positive test result means the patient has the disease.
,C. The proportion of people with the disease who test positive.
D. The likelihood that a negative test result is truly a ‘true negative’.
Answer: C
Rationale: Sensitivity measures the ability of a test to correctly identify individuals who
truly have the condition in question. A highly sensitive test is useful for screening because a
negative result effectively ‘rules out’ the disease. This is often summarized by the
mnemonic SNOUT (Sensitivity Negative Rules Out).
3. Which component of the SOAP note contains the patient’s description of their symptoms
and the history of the present illness?
A. Assessment
B. Objective
C. Subjective
D. Plan
Answer: C
Rationale: The Subjective section includes all information provided by the patient or their
caregiver, such as the Chief Complaint and Review of Systems. It reflects the patient’s
personal experience and perception of their health status. Documentation should ideally
include direct quotes to capture the patient’s perspective accurately.
, 4. A Nurse Practitioner (NP) performs a physical examination on a patient. In which section of
the SOAP note should the NP document the finding of ‘crackles in the left lower lung lobe’?
A. Objective
B. Subjective
C. Assessment
D. Plan
Answer: A
Rationale: The Objective section contains measurable, observable data collected by the
healthcare provider during the physical exam or from laboratory/imaging results. Findings
like lung auscultation are verifiable facts rather than patient-reported symptoms. Accurate
objective documentation is critical for monitoring the progression or resolution of a
condition.
5. Which cognitive bias occurs when a clinician relies too heavily on the first piece of
information encountered during the diagnostic process?
A. Anchoring Bias
B. Availability Heuristic
C. Confirmation Bias
D. Premature Closure
Answer: A
