1.
A 58-year-old patient with hypertension and type 2 diabetes
has a urine albumin-to-creatinine ratio of 420 mg/g and an
estimated GFR of 62 mL/min/1.73 m². Which medication is
most appropriate for renal and cardiovascular risk reduction in
addition to blood-pressure control?
A. Amlodipine
B. Hydrochlorothiazide
C. Lisinopril
D. Propranolol
Rationale: ACE inhibitors such as lisinopril reduce
intraglomerular pressure by inhibiting angiotensin II formation
and dilating the efferent arteriole. They are particularly
beneficial in patients with diabetes and albuminuria because
they reduce albuminuria and slow progression of chronic kidney
disease. Serum creatinine and potassium should be monitored
after initiation or dose escalation. Amlodipine and
hydrochlorothiazide can lower blood pressure but do not
,provide the same albuminuria-directed renal benefit.
Propranolol is not a preferred renal-protective antihypertensive
in this setting.
2.
A patient develops a persistent dry cough several weeks after
starting lisinopril. Which medication is the most appropriate
replacement when continued renin-angiotensin system
blockade is desired?
A. Clonidine
B. Losartan
C. Diltiazem
D. Spironolactone
Rationale: ACE-inhibitor-associated cough is related to
accumulation of bradykinin and other vasoactive peptides. An
angiotensin II receptor blocker (ARB), such as losartan, provides
renin-angiotensin system blockade without directly inhibiting
bradykinin degradation and therefore has a much lower
incidence of cough. Clonidine and diltiazem are not equivalent
substitutes for renal or cardiovascular indications.
Spironolactone may be useful for selected patients but carries a
greater risk of hyperkalemia and is not a routine replacement
for an ACE inhibitor.
3.
,A patient with heart failure with reduced ejection fraction is
taking an ACE inhibitor, evidence-based beta-blocker, and
mineralocorticoid receptor antagonist. Which additional
medication class has demonstrated reductions in heart-failure
hospitalization and cardiovascular death regardless of diabetes
status?
A. Alpha-1 blocker
B. Nondihydropyridine calcium-channel blocker
C. SGLT2 inhibitor
D. Thiazide diuretic
Rationale: Sodium-glucose cotransporter-2 (SGLT2) inhibitors
such as dapagliflozin and empagliflozin provide important
heart-failure benefits independent of diabetes status. They
reduce heart-failure hospitalization and cardiovascular events in
appropriate patients with reduced or preserved ejection
fraction. Alpha-1 blockers and thiazides do not provide the
same disease-modifying heart-failure benefit, while
nondihydropyridine calcium-channel blockers can worsen
systolic dysfunction because of negative inotropic effects.
4.
A patient taking spironolactone for heart failure has a
potassium concentration of 5.8 mEq/L. Which adverse effect of
spironolactone best explains this laboratory abnormality?
, A. Hypocalcemia
B. Hypernatremia
C. Hyperkalemia
D. Hypomagnesemia
Rationale: Spironolactone antagonizes aldosterone in the distal
nephron, reducing sodium reabsorption while decreasing
potassium and hydrogen ion excretion. Hyperkalemia is
therefore a clinically important adverse effect, particularly in
patients with chronic kidney disease or concomitant ACE
inhibitor, ARB, or potassium supplementation. Potassium and
renal function should be monitored after initiation and during
dose changes.
5.
A patient with hypertension and gout requires adjustment of
antihypertensive therapy. Which medication is most likely to
worsen hyperuricemia?
A. Losartan
B. Amlodipine
C. Hydrochlorothiazide
D. Carvedilol
Rationale: Thiazide diuretics decrease renal uric acid excretion
and can increase serum uric acid concentrations, potentially
precipitating gout. Losartan is distinctive among ARBs because
