Introduction
This Chamberlain NR 511 Differential Diagnosis & Primary Care I Midterm Exam format for
2026/2027 reflects the standardized competency assessment used to evaluate proficiency in
diagnostic reasoning and primary care management for Family Nurse Practitioner (FNP), Adult-
Gerontology Primary Care NP (AGPCNP), or other advanced practice nursing students at
Chamberlain University. The exam measures knowledge of differential diagnosis frameworks, acute
condition management, chronic disease fundamentals, diagnostic testing interpretation, evidence-
based guideline application, patient education strategies, pharmacologic considerations, referral
protocols, and scenario-based clinical decision-making essential for safe, effective, evidence-based
primary care practice.

Domain 1: Differential Diagnosis Methodology & Clinical Reasoning
Questions 1–4 | 4 Items
1. A 42-year-old female presents with a 3-day history of nasal congestion, clear
rhinorrhea, sore throat, and low-grade fever. The NP documents her visit using the
SOAP format. Which component of the SOAP note contains the patient's reported
symptom of 'worse nasal congestion in the morning'?
A) Subjective
B) Objective
C) Assessment
D) Plan
Answer: A) Subjective
Rationale: The Subjective section of the SOAP note captures the patient's reported symptoms,
history, and concerns in their own words. Objective findings are those measurable by the
clinician (vital signs, exam findings). Assessment is the clinician's diagnostic impression, and
Plan outlines management. The chief complaint and HPI belong in the Subjective section.
2. A nurse practitioner is evaluating a 55-year-old male with acute cough and wants to
determine whether obtaining a chest X-ray would reduce mortality. Which PICO
component corresponds to 'acute cough of less than 3 weeks' in this clinical question?
A) Intervention
B) Comparison
C) Outcome
D) Patient/Problem
Answer: D) Patient/Problem
Rationale: In the PICO framework: P = Patient/Problem (the clinical condition or population),
I = Intervention (the test, treatment, or exposure being considered), C = Comparison (the
alternative intervention or placebo), O = Outcome (the result being measured). 'Acute cough of
less than 3 weeks' describes the patient population and clinical problem being studied.
3. A rapid influenza diagnostic test (RIDT) has a sensitivity of 65% and a specificity of
98% for detecting influenza A. A previously healthy 30-year-old presents during flu
season with fever, myalgias, and cough. The RIDT result is negative. What is the most
appropriate interpretation?
A) The patient definitively does not have influenza
B) The specificity of 98% means the false-negative rate is only 2%
C) The positive predictive value is the most relevant metric in this scenario
D) A negative result cannot reliably rule out influenza due to low sensitivity
Answer: D) A negative result cannot reliably rule out influenza due to low sensitivity
Rationale: Sensitivity measures the proportion of true positives correctly identified (SnOUT:
when Sensitivity is high/adequate, a Negative result rules OUT disease). With low sensitivity
(65%), a negative test result has a high false-negative rate and cannot reliably exclude influenza.
Specificity (98%) means the test is very good at correctly identifying those without disease
(SpIN: when Specificity is high, a Positive result rules IN disease). The negative result should not
be interpreted as ruling out influenza, especially during peak flu season with a compatible
clinical presentation. CDC recommends clinical judgment when RIDT results are negative.
4. A 28-year-old female presents with a 10-day history of progressively worsening
headache, unilateral facial pressure, purulent nasal discharge, and maxillary tooth
pain. She reports no improvement with OTC decongestants. What is the most
