A nurse is caring for a client who has been taking captopril for one year. Which of the following laboratory values should the nurse review? (Select all that apply.)
Potassium level.
WBC with differential.
BUN level.
Hemoglobin level.
Glucose level.
Correct Answer : A,B,C
Choice A rationale
Potassium level should be reviewed because captopril can cause hyperkalemia due to its effect on aldosterone secretion.
Choice B rationale
WBC with differential should be reviewed because captopril can cause neutropenia or agranulocytosis, especially in patients with renal impairment or collagen vascular disease.
Choice C rationale
BUN level should be reviewed because captopril can affect renal function, leading to increased BUN levels.
Choice D rationale
Hemoglobin level is not typically affected by captopril, so it is not a priority for review.
Choice E rationale
Glucose level is not typically affected by captopril, so it is not a priority for review.

Correct Answer is C
Explanation
Choice A rationale
Mannitol is an osmotic diuretic used primarily to reduce intracranial pressure (ICP) and treat cerebral edema. It does not affect thyroxine levels, which are related to thyroid function. Thyroxine levels are regulated by the thyroid gland and are not influenced by mannitol administration.
Choice B rationale
Mannitol is not used to correct atrial flutter. Atrial flutter is a type of arrhythmia that requires specific antiarrhythmic medications or procedures such as cardioversion. Mannitol’s primary action is to increase osmotic pressure in the kidneys, leading to diuresis and reduction of fluid in tissues, including the brain.
Choice C rationale
Mannitol is effective in reducing intracranial pressure by creating an osmotic gradient that draws fluid from the brain tissue into the bloodstream, which is then excreted by the kidneys. This reduction in intracranial pressure is a desired therapeutic outcome when treating conditions like cerebral edema.
Choice D rationale
Mannitol does not increase hemoglobin levels. Hemoglobin levels are influenced by factors such as red blood cell production and destruction, iron levels, and overall health status. Mannitol’s mechanism of action is related to fluid balance and diuresis, not hematopoiesis.
Correct Answer is D
Explanation
Choice A rationale
Immediate-release exenatide pens should be discarded 30 days after the first use, not two months. This ensures the medication remains effective and free from contamination.
Choice B rationale
Exenatide is administered subcutaneously, not intramuscularly. The preferred injection sites are the abdomen, thigh, or upper arm.
Choice C rationale
Open exenatide pens should be stored at room temperature, but this is not the most critical aspect of patient education. Proper storage ensures the medication’s stability and effectiveness.
Choice D rationale
Immediate-release exenatide should be taken one hour before morning and evening meals to optimize its glucose-lowering effects by enhancing insulin secretion in response to meals.
