A nurse is preparing to administer medication to a client who has a prescription for epoetin alfa. Which of the following routes of administration should the nurse plan to use?

Choice A Reason:
Hypokalemia is correct. Hydrochlorothiazide is a thiazide diuretic that promotes the excretion of sodium and water in the kidneys, leading to increased urine production. However, it can also cause the loss of potassium (hypokalemia) as a side effect. Hypokalemia can manifest with symptoms such as muscle weakness, fatigue, irregular heart rhythms, and muscle cramps.
Choice B Reason:
Hypermagnesemia is incorrect. Hydrochlorothiazide typically promotes the loss of magnesium rather than causing elevated magnesium levels.
Choice C Reason:
Hypernatremia is incorrect. Hydrochlorothiazide is more likely to cause a decrease in sodium levels (hyponatremia) rather than an increase (hypernatremia).
Choice D Reason:
Hypocalcemia is incorrect. Hydrochlorothiazide can cause increased excretion of calcium but it's not a common adverse effect compared to the loss of potassium (hypokalemia).

Choice A Reason:
Blood pressure is correct. Nitroprusside is a medication used to lower blood pressure in conditions such as hypertensive emergencies. It's titrated based on blood pressure readings, with the goal of achieving the desired target blood pressure range as directed by the healthcare provider. The nurse would monitor the client's blood pressure closely and adjust the infusion rate accordingly to achieve the prescribed blood pressure parameters.
Choice B Reason:
Stroke volume is incorrect. While stroke volume (the amount of blood ejected by the heart with each contraction) is important in assessing heart function, it's not directly used to titrate a nitroprusside infusion. Nitroprusside primarily acts as a vasodilator to reduce blood pressure, rather than affecting stroke volume.
Choice C Reason:
Cardiac output is incorrect. Cardiac output (the volume of blood pumped by the heart per minute) is also a crucial measure of heart function, but adjusting a nitroprusside infusion based on cardiac output is not a common practice. Nitroprusside's primary action is to dilate blood vessels, impacting blood pressure regulation more directly than cardiac output.
Choice D Reason:
Urine output is incorrect. While urine output is an important indicator of renal function and overall fluid balance, it is not typically used as the main parameter for titrating nitroprusside. Nitroprusside's primary effect is on vasodilation and blood pressure control rather than directly impacting urine output.
