Correct Answer is A

Explanation

Choice A rationale

Hydralazine decreases blood pressure by vasodilation, improving renal perfusion and function. Enhanced kidney function promotes diuresis, balancing fluid levels and reducing hypertension.

Choice B rationale

While controlling blood pressure indirectly benefits liver health, hydralazine's primary effect on vasodilation does not directly support liver function.

Choice C rationale

Hydralazine primarily lowers blood pressure through vasodilation. Preventing arrhythmias is more directly associated with medications affecting cardiac conduction rather than vasodilators.

Choice D rationale

Lowering cholesterol levels is not a direct effect of hydralazine. Its primary action is reducing blood pressure through vascular smooth muscle relaxation, decreasing hypertension.

Correct Answer is ["36"]

Explanation

Step 1 is: Convert 10 units to milliunits: 10 units × 1,000 milliunits/unit = 10,000 milliunits.

Step 2 is: Calculate the infusion rate: (6 milliunits/min ÷ 10,000 milliunits) × 1,000 mL = 0.6 mL/min.

Step 3 is: Convert the infusion rate to mL/hour: 0.6 mL/min × 60 min/hour = 36 mL/hour. Final calculated answer: 36 mL/hour.
