Exam Overview & Instructions
About this Study Guide. This document contains 100 multiple-choice questions designed for graduate-level
advanced practice nursing students preparing for NSG 550 Exam 2 — Diagnostic Reasoning at Wilkes
University. Questions are vignette-led, requiring application of history-taking, physical examination,
diagnostic reasoning, and clinical formulation principles rather than rote recall. Each question has four options
(A-D) and is followed by a detailed rationale in the answer key section at the end.

Part I — Foundational H&P; & Diagnostic Reasoning
Principles
These questions cover history-taking fundamentals, physical exam techniques, core diagnostic reasoning models
(hypothetico-deductive, pattern recognition, Bayesian), cognitive biases, and screening principles.
Answer key at the end
Question 1
A 52-year-old female presents to the primary care clinic with a chief complaint of
"feeling tired all the time" for the past three months. She reports menorrhagia
over the same period. She has no significant past medical history and takes no
medications. On review of systems she denies chest pain, dyspnea, or pica. The
NP is formulating the history of present illness. Which attribute of the HPI is
currently MISSING and most important to elicit next?
A. Allergies and adverse drug reactions
B. Past surgical history and prior transfusions
C. Onset,character, and modifying factors of the fatigue
D. Family history of autoimmune disease
Question 2
A 68-year-old male is being evaluated for acute-onset dyspnea. The NP is
deciding between pattern recognition and the hypothetico-deductive model of
clinical reasoning. The patient has stable COPD and presents with two days of
increased sputum purulence and wheeze consistent with his typical exacerbation
pattern. Which reasoning approach is MOST appropriate in this scenario?
A. Hypothetico-deductive reasoning, because every dyspnea presentation
requires a fresh differential
B. Pattern recognition, because the presentation matches an established illness
script
C. Bayesian reasoning with pre-test probability calculation before any action
D. Trial-and-error reasoning with sequential empirical treatment attempts
Question 3
A 45-year-old female presents with a chief complaint of headache for 6 weeks.
During the interview, the NP forms an early hypothesis of tension-type headache
and subsequently asks only questions that support this diagnosis while not
exploring red flags such as visual changes, morning vomiting, or focal neurologic
deficits. Which cognitive bias is the NP demonstrating?
A. Anchoring bias
