Style Questions with Correct Answers &
Detailed Rationales | Verified & Reliable
Question 1
A 64-year-old patient reports progressive exertional dyspnea
and fatigue. On examination, the clinician notes a laterally
displaced point of maximal impulse and a sustained apical
impulse. Which underlying cardiac change most likely accounts
for these findings?
A. Right ventricular volume overload
B. Left ventricular hypertrophy
C. Pericardial effusion
D. Acute right ventricular infarction
Correct answer: B. Left ventricular hypertrophy
The point of maximal impulse becomes displaced laterally when
the left ventricle enlarges, and a sustained or heaving apical
impulse is characteristic of pressure overload and left
ventricular hypertrophy. Chronic hypertension and aortic
stenosis are common causes. Right ventricular enlargement
,may produce a left parasternal heave rather than a displaced
apical impulse. Pericardial effusion typically muffles heart
sounds and can make the PMI difficult to palpate.
Question 2
A patient with type 2 diabetes develops burning pain in both
feet that is worse at night. Examination reveals reduced
vibration and pinprick sensation in a symmetric stocking
distribution. Which pathophysiologic process best explains
these findings?
A. Focal compression of the median nerve
B. Immune-mediated destruction of peripheral myelin
C. Length-dependent peripheral nerve injury related to chronic
hyperglycemia
D. Ischemic injury from acute arterial occlusion
Correct answer: C. Length-dependent peripheral nerve injury
related to chronic hyperglycemia
Diabetic distal symmetric polyneuropathy typically begins in the
toes and progresses proximally in a length-dependent pattern.
Chronic hyperglycemia contributes to metabolic and
microvascular injury affecting peripheral nerves. Carpal tunnel
syndrome is a focal median neuropathy, whereas acute arterial
,occlusion causes sudden ischemic symptoms rather than chronic
symmetric sensory loss.
Question 3
A 72-year-old patient with hypertension is started on lisinopril.
Which laboratory abnormality requires the closest monitoring
after initiation and dose increases?
A. Decreased serum calcium
B. Increased serum creatinine and potassium
C. Decreased serum sodium only
D. Increased serum bicarbonate
Correct answer: B. Increased serum creatinine and potassium
ACE inhibitors reduce angiotensin II-mediated efferent arteriolar
constriction, which can reduce intraglomerular pressure and
cause an initial increase in serum creatinine. They also decrease
aldosterone secretion, increasing the risk of hyperkalemia.
Renal function and potassium should therefore be assessed
after initiation and appropriate dose changes, particularly in
patients with chronic kidney disease or other hyperkalemia
risks.
Question 4
, During examination of a patient with suspected meningitis, the
clinician observes resistance to passive neck flexion. Which
finding would provide additional support for meningeal
irritation?
A. Positive Kernig sign
B. Positive Phalen test
C. Positive Romberg test
D. Positive Allen test
Correct answer: A. Positive Kernig sign
Kernig and Brudzinski signs are classic examination findings
associated with meningeal irritation. A positive Kernig sign
occurs when extension of the knee with the hip flexed produces
pain or resistance. Phalen testing evaluates median nerve
compression at the wrist, Romberg testing evaluates balance
and proprioception, and the Allen test evaluates collateral
circulation of the hand.
Question 5
A patient presents with fatigue, constipation, cold intolerance,
dry skin, and bradycardia. Laboratory testing demonstrates an
elevated TSH and low free T4. Which mechanism most directly
accounts for the laboratory pattern?
