Introduction
,The NR-603 Advanced Clinical Diagnosis & Practice
Practicum examination assesses the advanced knowledge and
clinical reasoning skills required for independent diagnostic
and management decision-making in family nurse
practitioner practice. This examination evaluates competency
in hypothesis-driven diagnostic reasoning, comprehensive
patient assessment, differential diagnosis formulation,
evidence-based practice application, and management of
complex acute and chronic conditions across the lifespan. The
test employs multiple-choice and scenario-based questions
that simulate real-world clinical encounters in precepted
advanced practice settings. Emphasis is placed on diagnostic
accuracy, clinical judgment, patient-centered care, and
interdisciplinary collaboration. Candidates must demonstrate
the ability to synthesize complex clinical data, recognize
diagnostic errors, and implement safe, effective, and ethically
sound management plans consistent with the FNP scope of
practice.
SECTION ONE: QUESTIONS 1–100
1. A 58-year-old male presents with a 3-week history of
progressive dyspnea on exertion, orthopnea, and bilateral
lower extremity edema. He has a history of hypertension
,and a 40-pack-year smoking history. Which diagnostic
approach best reflects hypothesis-driven reasoning in this
patient?
A. Order a comprehensive metabolic panel and wait for
results before forming a clinical impression
B. Generate a prioritized differential diagnosis including
heart failure, COPD exacerbation, and pulmonary embolism,
then systematically evaluate each
C. Refer immediately to cardiology without initiating a
diagnostic workup
D. Obtain a chest X-ray only and treat empirically with
diuretics
🟢 Correct answer: B
🔴 RATIONALE: Hypothesis-driven reasoning involves
generating multiple diagnostic hypotheses early based on
the initial presentation and systematically testing each
through focused assessment. This approach reduces
cognitive bias and anchoring, which are leading causes of
diagnostic error in advanced practice.
2. A 45-year-old female presents with fatigue, weight gain,
cold intolerance, and constipation. Her TSH is elevated at
, 8.2 mIU/L and free T4 is low at 0.6 ng/dL. Which is the
most appropriate initial treatment?
A. Levothyroxine 1.6 mcg/kg/day orally on an empty
stomach
B. Liothyronine 5 mcg PO BID
C. Methimazole 10 mg PO daily
D. Radioactive iodine ablation
🟢 Correct answer: A
🔴 RATIONALE: The presentation and laboratory findings
are consistent with primary hypothyroidism. Levothyroxine is
the standard replacement therapy, dosed at approximately
1.6 mcg/kg/day, taken on an empty stomach for optimal
absorption.
3. A 28-year-old female presents with a 2-day history of
dysuria, urinary frequency, and suprapubic discomfort. She
has no fever, flank pain, or vaginal discharge. Which is the
most appropriate initial management?
A. Obtain a urine culture and await results before treatment
B. Prescribe nitrofurantoin monohydrate/macrocrystals 100
mg PO BID for 5 days
