Correct Answer is A

Explanation

Choice A Reason: Dobutamine is a positive inotropic agent that increases the contractility of the heart and improves cardiac output. This leads to increased renal perfusion and urine output, which reduces the fluid overload and edema associated with heart failure. Therefore, this choice is correct.

Choice B Reason: Dobutamine does not have a direct effect on blood glucose level. It may cause hyperglycemia as a side effect, but this is not an indication of its effectiveness. Therefore, this choice is incorrect.

Choice C Reason: Dobutamine may cause a slight decrease in blood pressure due to vasodilation, but this is not its main therapeutic effect. A significant decrease in blood pressure may indicate hypovolemia, hypotension, or shock, which are adverse effects of dobutamine. Therefore, this choice is incorrect.

Choice D Reason: Dobutamine also has a positive chronotropic effect, which means it increases the heart rate. However, this is not a desired outcome for a client with heart failure, as it increases the oxygen demand of the heart and may worsen the condition. Therefore, this choice is incorrect.
