NR 603 Advanced Clinical Diagnosis and Practice Midterm
Exam Practice Questions and Detailed Solutions Latest Update
2026/2027 | Clinical Reasoning, Diagnostic Testing, Verified
Answers - 199 Questions
This exam assesses advanced clinical reasoning, diagnostic testing interpretation, and evidence-based
decision-making in complex patient presentations. It covers differential diagnosis, test selection and
interpretation, integration of clinical data, and management planning at an advanced practice level. It contains
199 multiple-choice questions, each with four distractors and a fully worked rationale that explains why the keyed
answer is correct. Questions are organized into clearly labelled sections that mirror the major content areas of
the course. Targeted learning outcomes include: Apply advanced clinical reasoning to develop and prioritize
differential diagnoses.; Select and interpret diagnostic tests based on validity, reliability, and clinical utility.;
Integrate patient data to make evidence-based diagnostic and management decisions.; Recognize atypical
presentations and avoid diagnostic errors in complex cases.. Every item has been reviewed for clinical accuracy,
current guidelines, and clarity so that students can study with confidence and self-correct as they work through
the bank. Use it as a high-yield review immediately before the exam, or as a structured practice tool during the
unit - the rationales double as concise teaching notes. The recommended writing time is 3 hours, with a passing

Section 1: General (Questions 1-199)
1 A patient presents with acute chest pain, diaphoresis, and dyspnea.
ECG shows ST-segment elevation in leads II, III, and aVF. Which of
the following is the most appropriate immediate next step in
management?
A) Administer sublingual nitroglycerin and reassess in 5 minutes
B) Obtain a high-sensitivity troponin level before any intervention
C) Activate the catheterization laboratory for primary percutaneous
coronary intervention
D) Start intravenous heparin and admit to the intensive care unit
Answer: C
Rationale: STEMI in the inferior leads requires immediate reperfusion
therapy, preferably primary PCI, within 90 minutes of first medical
contact. Nitroglycerin may be given but does not delay reperfusion.
Troponin is not needed to initiate treatment. Heparin is adjunctive but
not the primary intervention.
,2 A patient with a history of hypertension and type 2 diabetes presents
with fatigue, orthostatic hypotension, and hyperpigmentation of the
skin. Lab results show hyponatremia, hyperkalemia, and low
cortisol. Which of the following is the most likely diagnosis?
A) Cushing's syndrome
B) Primary hyperaldosteronism
C) Addison's disease
D) Pheochromocytoma
Answer: C
Rationale: Addison's disease (primary adrenal insufficiency) presents
with fatigue, orthostatic hypotension, hyperpigmentation,
hyponatremia, hyperkalemia, and low cortisol. Cushing's syndrome
would have high cortisol, hyperaldosteronism would have
hypertension and hypokalemia, and pheochromocytoma presents with
episodic hypertension and headache.
3 A 25-year-old woman presents with fever, arthralgias, and a malar
rash. Laboratory tests show anemia, leukopenia, and a positive
antinuclear antibody (ANA). Which of the following additional
findings would most support the diagnosis of systemic lupus
erythematosus (SLE)?
A) Elevated C-reactive protein
B) Positive anti-dsDNA antibody
C) Positive rheumatoid factor
D) Low complement C3 and C4
Answer: B
Rationale: Anti-dsDNA is highly specific for SLE and is included in
the diagnostic criteria. Elevated CRP is nonspecific. Rheumatoid
factor is more associated with RA. Low complement is supportive but
not as specific as anti-dsDNA.
,4 A patient with a history of recurrent kidney stones presents with
colicky flank pain and hematuria. Which of the following is the
most appropriate initial imaging study?
A) Abdominal radiograph (KUB)
B) Non-contrast helical CT scan
C) Renal ultrasound
D) Intravenous pyelogram
Answer: B
Rationale: Non-contrast helical CT is the gold standard for diagnosing
urolithiasis due to high sensitivity and specificity for stone detection,
even for radiolucent stones. KUB misses many stones, ultrasound is
less sensitive for small stones, and IVP has been largely replaced by
CT.
5 A patient presents with a sudden onset of severe headache, neck
stiffness, and photophobia. Kernig's sign is positive. Which of the
following is the most appropriate next step in management?
A) Start empiric antibiotics and perform a lumbar puncture
immediately
B) Perform a CT scan of the head before lumbar puncture
C) Obtain blood cultures and start empiric antibiotics
D) Administer analgesics and observe for 24 hours
Answer: B
Rationale: In suspected meningitis, if there is any concern for
increased intracranial pressure (e.g., focal deficits, papilledema,
immunocompromise), a CT scan should be done before lumbar
puncture to prevent herniation. If CT is delayed, blood cultures should
be obtained and empiric antibiotics started, but the immediate next
step is CT.
, 6 A patient with a history of chronic obstructive pulmonary disease
(COPD) presents with increasing dyspnea and a productive cough
with purulent sputum. Which of the following findings would most
strongly indicate the need for hospitalization?
A) Respiratory rate of 24 breaths/min
B) Oxygen saturation of 92% on room air
C) Use of accessory muscles
D) Presence of comorbidities
Answer: C
Rationale: Use of accessory muscles indicates significant respiratory
distress and is a sign of impending respiratory failure, warranting
hospitalization. Tachypnea and mild hypoxia may be managed at
home, and comorbidities are a risk factor but not an immediate
indication alone.
7 A patient presents with a painful, swollen calf after a long flight.
D-dimer is elevated. Which of the following is the most appropriate
next step to confirm the diagnosis?
A) Repeat D-dimer in 6 hours
B) Compression ultrasonography of the lower extremity
C) Magnetic resonance venography
D) Computed tomography pulmonary angiography
Answer: B
Rationale: For suspected deep vein thrombosis (DVT), compression
ultrasonography is the first-line confirmatory test. It is noninvasive,
highly accurate, and readily available. CT pulmonary angiography is
for pulmonary embolism, not DVT. MRI venography is not first-line.
Repeating D-dimer is unnecessary.
8 A patient with a history of atrial fibrillation is taking warfarin. The
INR is 5.2, and the patient has no signs of bleeding. What is the
most appropriate management?
A) Administer vitamin K 10 mg intravenously
