Reasoning (Questions 1–40)
1. A 52-year-old female presents with complaints of progressive
fatigue, weight gain, cold intolerance, and dry skin. On
examination, the nurse practitioner notes bradycardia, delayed
deep tendon reflexes, and a palpable thyroid gland. Which
laboratory finding would MOST strongly support the suspected
diagnosis?
A. Elevated T3 with normal TSH
B. Elevated TSH with low free T4
C. Low TSH with elevated free T4
D. Normal TSH with elevated T3
Answer: B
Rationale: The patient's presentation is classic for primary hypothyroidism. In primary
hypothyroidism, the thyroid gland fails to produce adequate thyroid hormone, resulting
in low free T4 and a compensatory elevation in TSH. Options A and D are incorrect
because T3 elevation with normal or low TSH is not consistent with primary
hypothyroidism. Option C describes hyperthyroidism, which would present with
opposite symptoms (weight loss, tachycardia, heat intolerance).
,2. A 45-year-old male presents with acute onset of severe, sharp
chest pain that worsens with inspiration and improves when
leaning forward. He reports a recent upper respiratory infection.
On auscultation, a friction rub is heard at the left sternal border.
What is the MOST appropriate initial diagnostic test?
A. Chest X-ray
B. Electrocardiogram (ECG)
C. Complete blood count (CBC)
D. Cardiac enzymes
Answer: B
Rationale: The presentation of pleuritic chest pain that worsens with inspiration,
improves with leaning forward, and is accompanied by a friction rub is classic for
pericarditis. An ECG is the initial diagnostic test of choice, as it typically shows diffuse
ST-segment elevation and PR depression in pericarditis. Option A is less specific for
pericarditis. Option C is not diagnostic for this condition. Option D would be more
appropriate for myocardial infarction, which presents differently.
3. A 68-year-old male with a 45-pack-year smoking history
presents with a chronic cough, hemoptysis, and unintentional
weight loss of 15 pounds over 3 months. A chest X-ray reveals a 4
cm mass in the right upper lobe. Which symptom is MOST
concerning for malignancy?
A. Chronic cough
B. Hemoptysis
C. Weight loss
D. Smoking history
Answer: C
Rationale: While all these findings are concerning, unintentional weight loss in the
context of a lung mass is a systemic sign that strongly suggests malignancy.
,Hemoptysis, though concerning, can occur with benign conditions such as bronchitis or
bronchiectasis. Weight loss in the presence of a pulmonary mass is a classic red flag for
lung cancer and warrants prompt evaluation. Options A and D are risk factors but less
specific indicators of malignancy.
4. A nurse practitioner performs a funduscopic examination and
notes sharp optic disc margins, normal cup-to-disc ratio, and no
hemorrhages or exudates. This finding is consistent with:
A. Papilledema
B. Normal funduscopic examination
C. Glaucoma
D. Hypertensive retinopathy
Answer: B
Rationale: A normal funduscopic examination reveals sharp optic disc margins, a cup-
to-disc ratio of 0.3 or less, and an absence of hemorrhages, exudates, or cotton-wool
spots. Papilledema (Option A) would show blurred disc margins and venous
engorgement. Glaucoma (Option C) would show increased cup-to-disc ratio.
Hypertensive retinopathy (Option D) would show arteriolar narrowing, nicking, and
exudates.
5. A 35-year-old female presents with right upper quadrant pain,
nausea, and vomiting after eating a fatty meal. Murphy's sign is
positive on examination. Which diagnostic test is MOST
appropriate for initial evaluation?
A. Abdominal CT scan
B. Right upper quadrant ultrasound
C. ERCP
D. HIDA scan
, Answer: B
Rationale: The presentation of right upper quadrant pain after fatty meals with a
positive Murphy's sign is classic for cholecystitis. A right upper quadrant ultrasound is
the initial imaging study of choice, as it can visualize gallstones, gallbladder wall
thickening, and pericholecystic fluid. Option A is not the first-line test. Option C is
invasive and used for therapeutic purposes. Option D is used when ultrasound is
inconclusive.
6. A 60-year-old diabetic patient presents with a non-healing
ulcer on the plantar surface of the right foot. The ulcer is deep,
extends to bone, and has a foul odor. The surrounding skin is
erythematous and warm. What is the MOST appropriate next
step?
A. Debridement and wound culture
B. MRI of the foot
C. X-ray of the foot
D. MRI with contrast
Answer: B
Rationale: This patient has a deep plantar ulcer that extends to bone with signs of
infection. In a diabetic patient with a foot ulcer that probes to bone, osteomyelitis must
be ruled out. MRI is the most sensitive and specific imaging modality for detecting
osteomyelitis in the diabetic foot. X-ray (Option C) may show bone changes but is less
sensitive in early osteomyelitis. Debridement and culture (Option A) are appropriate but
should be preceded by or accompanied by imaging to assess bone involvement.
7. A 42-year-old female presents with complaints of bilateral hand
pain and stiffness that is worse in the morning and lasts for over 1
hour. She also reports fatigue and dry eyes. On examination, there
