A 65-year-old male with a history of hypertension presents with acute onset of
severe chest pain radiating to the back. Blood pressure is 100/60 mmHg in the right
arm and 140/90 mmHg in the left arm. Which pathophysiology is most likely
responsible for these findings?
A) Atherosclerotic plaque rupture with thrombus formation
B) Dissection of the aortic intima with propagation into the aortic arch
C) Vasospasm of the coronary arteries leading to myocardial ischemia
D) Rupture of a cerebral aneurysm with sympathetic surge
CORRECT ANSWER: B) Dissection of the aortic intima with propagation into the
aortic arch
Rationale: Aortic dissection often presents with severe tearing chest pain radiating
to the back and unequal blood pressures between arms due to involvement of the
brachiocephalic or subclavian arteries. Hypertension is a major risk factor. The
intimal tear allows blood to enter the media, propagating distally or proximally.
Option A describes acute coronary syndrome; option C describes Prinzmetal
angina; option D describes subarachnoid hemorrhage, none of which typically
cause unequal arm BPs.
A patient with type 2 diabetes mellitus has a fasting plasma glucose of 180 mg/ld.
and HbA1c of 8.5%. Current medications include metformin 1000 mg twice daily.
Which pharmacologic addition is most appropriate as second-line therapy
according to current guidelines?
,A) Insulin glargine
B) Sulfonylurea (glipizide)
C) SGLT2 inhibitor (empagliflozin)
D) Meglitinide (repaginate)
CORRECT ANSWER: C) SGLT2 inhibitor (empagliflozin)
Rationale: For patients with type 2 diabetes inadequately controlled on metformin,
SGLT2 inhibitors are preferred when cardiovascular or renal benefits are desired.
Empagliflozin reduces cardiovascular mortality and slows chronic kidney disease
progression. While sulfonylureas and insulin are options, SGLT2 inhibitors are
often preferred due to lower risk of hypoglycemia and weight gain. Meglitinides
are shorter-acting but less commonly used as second-line.
During a physical examination, a 45-year-old woman reports a "lump" in her neck.
On palpation, you feel a smooth, firm, non-tender nodule in the left thyroid lobe
that moves with swallowing. Which finding on examination would most increase
suspicion for malignancy?
A) Nodule size of 1.2 cm
B) Presence of cervical lymphadenopathy ipsilateral to the nodule
C) Complete suppression of TSH
D) No family history of thyroid disease
CORRECT ANSWER: B) Presence of cervical lymphadenopathy ipsilateral to the
nodule
Rationale: Malignant thyroid nodules may metastasize to regional cervical lymph
nodes. Palpable lymphadenopathy ipsilateral to a thyroid nodule is a red flag for
malignancy. Nodule size >4 cm increases risk, but 1.2 cm is small. Suppressed
TSH suggests a hyper functioning nodule (usually benign). Lack of family history
does not raise suspicion.
,A 70-year-old man with heart failure with reduced ejection fraction (Here) is on
Lisinopril, carvedilol, and furosemide. His creatinine is 1.9 mg/ld. (baseline 1.1)
and potassium is 5.8 me/L. Which medication should be held first?
A) Carvedilol
B) Lisinopril
C) Furosemide
D) All three should be continued
CORRECT ANSWER: B) Lisinopril
Rationale: Lisinopril (an ACE inhibitor) can cause hyperkalemia and acute kidney
injury, especially in the setting of heart failure and diuretic use. A potassium of 5.8
me/L is a contraindication to continuing ACE inhibitors. Carvedilol does not
typically cause hyperkalemia. Furosemide may actually lower potassium. The ACE
inhibitor should be held and the patient evaluated for further management.
A 28-year-old woman presents with episodic palpitations, sweating, and headache.
During an episode, blood pressure is 210/110 mmHg. Between episodes, she is
normotensive. Which physical examination finding is most likely to be present
during a symptomatic episode?
A) Tachycardia and pallor
B) Bradycardia and facial flushing
C) Orthostatic hypotension
D) Unilateral leg edema
CORRECT ANSWER: A) Tachycardia and pallor
Rationale: These symptoms and signs are classic for a pheochromocytoma, a
catecholamine-secreting tumor. During paroxysmal release of
epinephrine/norepinephrine, patients experience hypertension, tachycardia (though
reflex bradycardia can occur with pure norepinephrine surge, tachycardia is more
common), sweating, headache, and pallor. Flushing may occur but bradycardia is
, less typical. Orthostatic hypotension can occur but is not characteristic during an
episode.
Which pharmacology principle explains why a drug with a high volume of
distribution (Veda) is more difficult to remove by hemodialysis?
A) The drug is highly protein-bound
B) The drug is extensively distributed into tissues
C) The drug has a short half-life
D) The drug undergoes extensive first-pass metabolism
CORRECT ANSWER: B) The drug is extensively distributed into tissues
Rationale: Volume of distribution (Veda) reflects the extent to which a drug
distributes into tissues relative to plasma. A high Veda means most drug is in
extravascular compartments, not accessible to hemodialysis, which only removes
drug from the blood. Protein binding (A) also affects dialysis but is separate. Half-
life (C) and first-pass metabolism (D) are not direct explanations.
A 60-year-old smoker presents with progressive shortness of breath, chronic
cough, and barrel-shaped chest. On auscultation, breath sounds are distant with
prolonged expiration. Which physical examination maneuver best confirms the
presence of hyperinflation?
A) Increased tactile fremitus
B) Decreased diaphragmatic excursion on percussion
C) Broncho phony with whispered pectoriloquy
D) Geophony over the lung bases
CORRECT ANSWER: B) Decreased diaphragmatic excursion on percussion
Rationale: Hyperinflation in COPD flattens the diaphragm, reducing its descent
during inspiration. Percussing the diaphragmatic excursion (from full expiration to
