, Question 1
A patient with a known history of heart failure presents with bilateral basilar
crackles that do not clear with coughing. Which underlying mechanism best
explains this finding?
A. Inflammation of the pleural surfaces
B. Fluid in the alveoli from pulmonary edema
C. Air trapping in the distal airways
D. Mucus plugging in the bronchi
Correct Answer: B - Fluid in the alveoli from pulmonary edema
RATIONALE
Bilateral basilar crackles that persist after coughing are classic for
pulmonary edema due to left ventricular failure, where increased
hydrostatic pressure forces fluid into alveoli. Pleural inflammation
causes friction rub, air trapping causes wheezing, and mucus plugging
causes coarse crackles that may clear with cough.
Question 2
During a mental status examination, a patient is unable to recall three objects
after five minutes but can repeat them immediately. This finding is most
consistent with:
A. Impaired attention
B. Impaired immediate memory
C. Impaired recent memory
D. Impaired remote memory
Correct Answer: C - Impaired recent memory
Page 2
, RATIONALE
Inability to recall after a delay indicates impaired recent memory
(encoding/storage), while immediate recall is intact. Attention is tested
by digit span; immediate memory by repeating; remote memory by
recalling past events. This pattern is typical of early Alzheimer's
disease.
Question 3
Which cranial nerve is assessed by asking the patient to shrug the shoulders
against resistance?
A. Cranial nerve X (Vagus)
B. Cranial nerve XI (Spinal accessory)
C. Cranial nerve XII (Hypoglossal)
D. Cranial nerve IX (Glossopharyngeal)
Correct Answer: B - Cranial nerve XI (Spinal accessory)
RATIONALE
The spinal accessory nerve (CN XI) innervates the
sternocleidomastoid and trapezius muscles, enabling shoulder shrug
and head rotation. CN X controls gag reflex and voice; CN XII
controls tongue movement; CN IX aids swallowing and taste.
Question 4
A patient reports a burning sensation in the epigastric area that worsens when
lying down and is relieved by sitting upright. Which condition is most likely?
A. Peptic ulcer disease
B. Gastroesophageal reflux disease (GERD)
C. Acute pancreatitis
D. Cholecystitis
Correct Answer: B - Gastroesophageal reflux disease (GERD)
Page 3
, RATIONALE
GERD classically causes burning epigastric pain that worsens when
supine due to acid reflux and is relieved by sitting up or antacids.
Peptic ulcer pain is often gnawing and may be relieved or worsened by
food; pancreatitis causes constant severe pain radiating to back;
cholecystitis causes RUQ pain with fatty food intake.
Question 5
When assessing a patient with suspected carpal tunnel syndrome, which test is
most specific?
A. Phalen's test
B. Tinel's sign
C. Finkelstein's test
D. Allen's test
Correct Answer: A - Phalen's test
RATIONALE
Phalen's test (wrist flexion for 60 seconds) has higher specificity for
carpal tunnel syndrome. Tinel's sign is sensitive but less specific.
Finkelstein's test assesses de Quervain's tenosynovitis; Allen's test
evaluates radial/ulnar artery patency.
Question 6
A patient presents with sudden onset of severe, sharp chest pain that radiates to
the back, along with a blood pressure differential between arms. Which
assessment finding is most concerning for aortic dissection?
A. Pulse deficit in the radial artery
B. Murmur at the apex
C. Jugular venous distension
D. Pericardial friction rub
Correct Answer: A - Pulse deficit in the radial artery
