Question: When performing a breast exam on a 70-year-old patient, the nurse
practitioner notes bilateral, symmetrical, stringy lumps in the upper outer
quadrants. The patient has no complaints. What is the most appropriate initial
action?
A. Order a diagnostic mammogram.
B. Reassure the patient that this is a normal finding.
C. Perform a fine-needle aspiration.
D. Refer to a general surgeon for a biopsy.
CORRECT ANSWERS : B. Reassure the patient that this is a normal finding.
Rationale: This description is classic for fibrocystic changes, which are common
and benign. In a 70-year-old, involution of glandular tissue into fatty tissue is
more common, but persistent fibrocystic changes can occur. Without concerning
features (e.g., fixation, skin changes, nipple discharge), reassurance is the most
appropriate first step.
Question: A patient presents with acute onset of "the worst headache of my life."
Which diagnostic test is most critical?
A. Lumbar Puncture
B. Non-Contrast Head CT
C. EEG
D. MRI of the Brain
CORRECT ANSWERS : B. Non-Contrast Head CT
Rationale: A sudden, severe "thunderclap" headache is the classic presentation
for a subarachnoid hemorrhage. A non-contrast head CT is the fastest and most
sensitive initial test to rule out acute bleeding.
,Question: During a cardiac exam, a grade III/VI, mid-systolic murmur is heard best
at the 2nd right intercostal space. It radiates to the carotids. What is the most
likely cause?
A. Mitral Valve Prolapse
B. Aortic Stenosis
C. Tricuspid Regurgitation
D. Ventricular Septal Defect
CORRECT ANSWERS : B. Aortic Stenosis
Rationale: A systolic murmur at the 2nd right intercostal space (aortic area) that
radiates to the carotids is characteristic of aortic stenosis.
Question: A patient with a history of COPD presents with increased dyspnea and
purulent sputum. On exam, you note dullness to percussion, decreased breath
sounds, and egophony over the right lower lobe. What is the most likely finding
on chest x-ray?
A. Hyperinflation
B. Lobar Consolidation
C. Pleural Effusion
D. Pneumothorax
CORRECT ANSWERS : B. Lobar Consolidation
Rationale: Egophony (where "E" sounds like "A") is a sign of consolidation, as
sound transmission is improved through a solidified lung. This, combined with the
clinical picture, points to pneumonia with lobar consolidation.
Question: The Babinski sign is tested by:
A. Tapping the Achilles tendon with a reflex hammer.
,B. Stroking the lateral sole of the foot from heel to toe.
C. Assessing rapid alternating movements of the hands.
D. Testing the ability to sense vibration with a tuning fork.
CORRECT ANSWERS : B. Stroking the lateral sole of the foot from heel to toe.
Rationale: The Babinski test assesses the integrity of the corticospinal tract. In
adults, an upward extension of the great toe (positive Babinski) is abnormal and
indicates upper motor neuron disease.
Domain: Diagnosis
Question: A 55-year-old male with a 40-pack-year smoking history presents with
hemoptysis, weight loss, and a new cough. Chest x-ray reveals a 3-cm spiculated
mass in the left upper lobe. What is the most definitive diagnostic test?
A. Sputum Cytology
B. Low-dose CT Scan
C. Bronchoscopy with biopsy
D. Pulmonary Function Tests
CORRECT ANSWERS : C. Bronchoscopy with biopsy
Rationale: While imaging is suggestive, a tissue diagnosis is required to confirm
lung cancer. Bronchoscopy allows for direct visualization and biopsy of the lesion.
Question: A 25-year-old female presents with amenorrhea, galactorrhea, and
headaches. Which lab test is most indicative of the underlying diagnosis?
A. Thyroid-Stimulating Hormone (TSH)
B. Prolactin Level
C. Follicle-Stimulating Hormone (FSH)
, D. Human Chorionic Gonadotropin (hCG)
CORRECT ANSWERS : B. Prolactin Level
Rationale: The triad of amenorrhea, galactorrhea, and headaches is highly
suggestive of a prolactin-secreting pituitary adenoma. An elevated prolactin level
confirms the diagnosis.
Question: A patient with Type 2 Diabetes is found to have a hemoglobin A1c of
8.5% and a serum creatinine of 2.1 mg/dL (up from 1.2 mg/dL six months ago).
What is the most likely diagnosis?
A. Diabetic Ketoacidosis
B. Acute Tubular Necrosis
C. Diabetic Nephropathy
D. Contrast-Induced Nephropathy
CORRECT ANSWERS : C. Diabetic Nephropathy
Rationale: The slow, progressive rise in creatinine in a patient with poorly
controlled diabetes (A1c >7%) is classic for diabetic nephropathy, a microvascular
complication.
Question: A patient presents with recurrent, painful oral ulcers, genital ulcers, and
uveitis. The most likely diagnosis is:
A. Syphilis
B. Herpes Simplex Virus
C. Behçet's Disease
D. Crohn's Disease
CORRECT ANSWERS : C. Behçet's Disease
Rationale: The classic triad for Behçet's disease is recurrent oral aphthous ulcers,
genital ulcers, and uveitis. It is a systemic vasculitis.
