, Question 1
A patient with a history of heart failure presents with jugular venous
distension, positive hepatojugular reflux, and an S3 gallop. Which
pathophysiologic mechanism best explains the hepatojugular reflux finding?
A. Increased right atrial pressure from impaired right ventricular
compliance
B. Decreased left ventricular end-diastolic volume
C. Increased pulmonary capillary wedge pressure
D. Decreased systemic vascular resistance
Correct Answer: A - Increased right atrial pressure from
impaired right ventricular compliance
RATIONALE
Hepatojugular reflux reflects the inability of the right heart to
accommodate increased venous return, leading to sustained jugular
venous distension; it indicates elevated right atrial pressure and right
ventricular failure. The other options describe left-sided or systemic
changes that do not directly explain this specific venous congestion
sign.
Question 2
During a mental status examination, a patient demonstrates impaired executive
function and poor judgment despite intact memory and attention. Which
screening tool is most appropriate to further assess these specific deficits?
A. Mini-Mental State Examination (MMSE)
B. Montreal Cognitive Assessment (MoCA)
C. Clock Drawing Test
D. Confusion Assessment Method (CAM)
Correct Answer: B - Montreal Cognitive Assessment (MoCA)
Page 2
, RATIONALE
The MoCA is specifically designed to detect mild cognitive
impairment and has higher sensitivity for executive dysfunction than
the MMSE, which focuses more on memory and orientation. The
Clock Drawing Test assesses visuospatial and executive function but
is less comprehensive, and the CAM is used for delirium screening,
not executive function.
Question 3
Which physical examination technique is most sensitive for detecting early
ascites in a patient with suspected liver cirrhosis?
A. Fluid wave test
B. Shifting dullness
C. Puddle sign
D. Ballottement
Correct Answer: C - Puddle sign
RATIONALE
The puddle sign is the most sensitive maneuver for detecting as little
as 120 mL of ascitic fluid, as it identifies fluid accumulation in the
dependent portion of the abdomen when the patient is on hands and
knees. Shifting dullness and fluid wave require larger volumes (500
mL and 1000 mL, respectively), and ballottement is used for organ
palpation, not ascites detection.
Question 4
A patient presents with sudden onset of severe, sharp chest pain that radiates to
the back, along with a blood pressure differential of 20 mm Hg between arms.
Which assessment finding is most critical to obtain next?
A. Electrocardiogram (ECG) to rule out myocardial infarction
B. Bilateral upper extremity blood pressures and pulse checks
C. Auscultation for a pericardial friction rub
Page 3
, D. Measurement of oxygen saturation
Correct Answer: B - Bilateral upper extremity blood pressures
and pulse checks
RATIONALE
The presentation is highly suspicious for aortic dissection; confirming
interarm blood pressure differential and pulse deficits is critical for
rapid diagnosis and guiding immediate imaging. ECG may be normal
or nonspecific, a pericardial rub suggests pericarditis, and oxygen
saturation is supportive but not diagnostic.
Question 5
When performing a cranial nerve examination, which finding would most
likely indicate a lesion of the oculomotor nerve (CN III)?
A. Inability to shrug the shoulders against resistance
B. Loss of gag reflex
C. Ptosis, dilated pupil, and eye deviation downward and outward
D. Facial asymmetry with inability to close the eye
Correct Answer: C - Ptosis, dilated pupil, and eye deviation
downward and outward
RATIONALE
CN III innervates the levator palpebrae and most extraocular muscles;
a complete lesion causes ptosis, a fixed dilated pupil, and the eye
resting downward and outward due to unopposed superior oblique and
lateral rectus action. The other options describe deficits of CN XI, CN
IX/X, and CN VII, respectively.
Question 6
A patient with a history of intravenous drug use presents with fever, a new
diastolic murmur at the left lower sternal border, and splinter hemorrhages.
