Interactive Cardiology MCQs 32: Hypertension - All About Cardiovascular System and Disorders

Q1

The landmark SPRINT trial evaluated intensive versus standard blood pressure control. What was the primary finding regarding the intensive treatment target (systolic BP less than 120 mmHg) in non-diabetic adults at high cardiovascular risk?

Q2

According to the PATHWAY-2 trial, which pharmacological agent is the most effective add-on (fourth-line) therapy for patients with resistant hypertension already taking an ACE inhibitor/ARB, calcium channel blocker, and a thiazide-like diuretic?

Q3

When screening for Primary Aldosteronism in a hypertensive patient, the Aldosterone-to-Renin Ratio (ARR) is the recommended first step. Which pattern of plasma aldosterone concentration (PAC) and plasma renin activity (PRA) strongly indicates Primary Aldosteronism?

Q4

After a positive screening test for Primary Aldosteronism (high ARR), a confirmatory test must be performed. Which of the following is an accepted confirmatory test demonstrating autonomous aldosterone secretion?

Q5

A young patient presents with severe hypertension, hypokalemia, and metabolic alkalosis. Laboratory testing reveals LOW plasma renin activity AND LOW plasma aldosterone levels. What is the most likely genetic diagnosis?

Q6

Why are ACE inhibitors and ARBs strictly contraindicated in patients with bilateral renal artery stenosis (or unilateral stenosis in a solitary kidney)?

Q7

A 28-year-old female presents with new-onset, severe hypertension. Renal angiography reveals a “string of beads” appearance in the mid-to-distal right renal artery. What is the most likely diagnosis?

Q8

In the preoperative pharmacological preparation of a patient with a confirmed Pheochromocytoma, what is the mandatory sequence of autonomic receptor blockade?

Q9

A 15-year-old male is found to have severe hypertension in his upper extremities but weak, delayed femoral pulses. A chest X-ray reveals bilateral inferior rib notching. What is the mechanism behind this radiographic finding?

Q10

A patient presents to the ER with ‘tearing’ chest pain radiating to the back. A CT angiogram confirms an acute Stanford Type B Aortic Dissection. His blood pressure is 220/120 mmHg. What is the immediate target for blood pressure management?

Q11

In a patient presenting with an Acute Ischemic Stroke who is NOT a candidate for thrombolytic therapy (tPA) or mechanical thrombectomy, at what blood pressure threshold should pharmacological antihypertensive treatment be initiated?

Q12

Which of the following antihypertensive medications is strictly CONTRAINDICATED in pregnancy due to known severe teratogenicity, including fetal renal dysgenesis and oligohydramnios?

Q13

A patient receiving a prolonged, high-dose intravenous infusion of Sodium Nitroprusside for a hypertensive emergency develops altered mental status, lactic acidosis, and an almond-like breath odor. What is the appropriate specific antidote?

Q14

What is the clinical definition of ‘Masked Hypertension’ as identified by Ambulatory Blood Pressure Monitoring (ABPM)?

Q15

Based on the ALLHAT trial and current ACC/AHA guidelines, which two drug classes are the recommended initial monotherapy options for managing uncomplicated primary hypertension in Black patients?

Q16

Thiazide diuretics (e.g., Hydrochlorothiazide, Chlorthalidone) have a specific metabolic side effect profile that can be remembered by the mnemonic ‘HyperGLUC’. Which of the following metabolic disturbances is NOT typically caused by thiazides?

Q17

Hypertensive Encephalopathy is a severe manifestation of a hypertensive emergency characterized by headache, altered mental status, and seizures. What is the fundamental pathophysiological mechanism driving this condition?

Q18

Historically, “Malignant Hypertension” was defined by severe blood pressure elevation accompanied by specific ophthalmologic findings on fundoscopy. According to the Keith-Wagener-Barker classification, what Grade IV finding specifically defines malignant hypertension?

Q19

Obstructive Sleep Apnea (OSA) is a leading cause of secondary and resistant hypertension. What is the primary pathophysiological mechanism linking intermittent nocturnal hypoxia to sustained systemic hypertension?

Q20

A patient undergoing solid organ transplantation develops severe de novo hypertension shortly after starting their immunosuppressive regimen. Which of the following drug classes is notoriously responsible for this via profound renal afferent arteriolar vasoconstriction?

Q21

According to the widely adopted 2017 ACC/AHA High Blood Pressure Guidelines, what blood pressure readings strictly define “Stage 2 Hypertension”?

Q22

When transitioning a hypertensive heart failure patient from an ACE inhibitor (e.g., Lisinopril) to an ARNI (Sacubitril/Valsartan), a mandatory washout period is required. What is the correct duration and primary clinical rationale for this washout?

Q23

Dihydropyridine calcium channel blockers (like Amlodipine) frequently cause dose-dependent peripheral edema. What is the fundamental hemodynamic mechanism of this specific side effect?

Q24

Abrupt discontinuation of which centrally-acting antihypertensive agent is most famous for causing a severe ‘rebound hypertension’ crisis due to an acute massive outpouring of catecholamines?

Q25

Isolated Systolic Hypertension (ISH) is the most common form of hypertension in the elderly population (e.g., BP 170/70 mmHg). What is the primary pathophysiological driver of this specific pattern?
