A.

Severe dehydration

B.

Renal calculi

C.

Polycystic kidney disease

Glomerulonephritis

Answer and Explanation

The Correct Answer is A

(A) Severe Dehydration: Prerenal AKI is caused by reduced blood flow to the kidneys. Dehydration leads to hypovolemia, reducing renal perfusion and causing AKI.

(B) Renal Calculi: Postrenal AKI, not prerenal.

(C) Polycystic Kidney Disease: Chronic kidney disease, not acute.

(D) Glomerulonephritis: Intrarenal AKI, due to direct kidney damage

Explanation

(A) Positive Inotropic Effect: Sotalol does not increase contractility; it weakens contractions, making it a negative inotrope.

(B) Hypertension: Sotalol primarily lowers blood pressure and heart rate, which can actually cause hypotension.

(C) Negative Inotropic Effect: Sotalol is a beta-blocker that decreases myocardial contractility, which can further reduce cardiac output in heart failure patients.

(D) Hypercholesterolemia: Sotalol does not significantly impact cholesterol levels.
