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 B
Explanation
Choice A rationale
Crushing tadalafil is not recommended as it can alter the medication’s effectiveness and absorption. Tadalafil should be taken whole to ensure proper dosage and efficacy.
Choice B rationale
Tadalafil can decrease blood pressure by relaxing blood vessels, which allows for increased blood flow. This is a known effect of phosphodiesterase type 5 (PDE5) inhibitors like tadalafil.
Choice C rationale
Tadalafil should not be taken more than once a day. Taking it twice a day can increase the risk of side effects and is not recommended.
Choice D rationale
The effects of tadalafil can last up to 36 hours, not just 4 hours. This prolonged duration is one of the reasons it is preferred by some patients.
Correct Answer is E
Explanation
Choice A rationale
Hypercalcemia is not typically a risk in the emergency department unless the patient has a specific condition that causes elevated calcium levels.
Choice B rationale
Hypotension can occur in the emergency department, especially in cases of shock or severe dehydration, but it is not the most common risk.
Choice C rationale
Hypokalemia can occur, particularly in patients with certain medical conditions or those taking diuretics, but it is not the most common risk.
Choice D rationale
Hypernatremia can occur, especially in patients with dehydration or certain medical conditions, but it is not the most common risk.
Choice E rationale
Hypoglycemia is a common risk in the emergency department, especially in patients with diabetes or those who have not eaten for an extended period.
