Examination Overview
This comprehensive 135-question examination covers nutrition fundamentals, macronutrients, micronutrients,
nutritional assessment, lifespan nutrition, nutrition support, therapeutic diets, food safety, drug-nutrient
interactions, cultural considerations, and patient education for nursing practice. The exam is organized into nine
sections reflecting the major nutrition content areas aligned with the PNR 207 Course Competency Blueprint
including the 2026/2027 PNR 207 course competencies and capstone assessment blueprint. Each question
includes a detailed rationale with practical nursing clinical reasoning, scope considerations, and study guide
value for capstone exam preparation.
Cognitive Level Distribution
Questions are distributed across cognitive levels: approximately 25% recall (knowledge of nutrient functions,
sources, and dietary guidelines), 55% application (clinical reasoning in nutrition scenarios with dietary
selection, and 20% analysis (complex nutrition therapy decisions, dietary modification, and lab interpretation).
Approximately 75% of questions are scenario-based, reflecting the PNR 207 Capstone Exam 2 format.

Section 1: Clinical Reasoning and Advanced Diagnostic Strategy | Q1-17 questions
Q1. A 72-year-old male presents with fatigue, weight loss, and night sweats for 3 months. Which
diagnostic strategy is MOST appropriate for generating a differential diagnosis?
A. Focus exclusively on malignancy workup
B. Use a hypothesis-driven approach generating a prioritized list based on probability, urgency, and risk
[CORRECT] [CORRECT]
C. Order a complete body scan immediately
D. Treat empirically for depression and reassess
Correct Answer: B
Rationale: A hypothesis-driven approach generates a prioritized differential based on disease probability,
urgency (cannot-miss conditions), and patient risk factors. Choice A narrows prematurely. Choice C is not
evidence-based. Choice D risks missing serious disease. Study Tip: Vindicial (anatomic/physiologic)
reasoning and probabilistic reasoning should complement hypothesis-driven diagnosis.
Q2. Which principle should guide diagnostic test selection in an 80-year-old with multiple
comorbidities?
A. Order the most tests possible to be thorough
B. Select tests that will change management decisions, considering sensitivity, specificity, and patient
values [CORRECT] [CORRECT]
C. Defer all testing due to age
D. Order only imaging studies
Correct Answer: B
Rationale: Test selection should be guided by whether results will change management. Sensitivity (rule
out), specificity (rule in), positive/negative predictive value, and patient values/comorbidities all factor in.
Ordering unnecessary tests in older adults leads to incidentalomas, complications, and cost. Study Tip: Use
likelihood ratios to estimate post-test probability. A test is only useful if it changes the pre-test probability
enough to alter management.
Q3. A 68-year-old female has a pre-test probability of 15% for PE. A D-dimer is negative (high
sensitivity). What is the best interpretation?
A. PE is ruled out; the negative likelihood ratio of a normal D-dimer effectively lowers the post-test
probability below the testing threshold [CORRECT] [CORRECT]
B. PE is confirmed; admit immediately
C. Repeat the D-dimer in 24 hours
D. Proceed to CT angiography regardless
Correct Answer: A
Rationale: A negative D-dimer (sensitivity ~97%) in a patient with low-to-moderate pre-test probability
effectively rules out PE (PERC/Wells criteria). The negative likelihood ratio is very low, dropping post-test
probability below the testing threshold. Choice B is wrong (negative test). Choice C is unnecessary. Choice
