A nurse is caring for a client who has prescriptions for spironolactone and lisinopril. The nurse should monitor for which of the following adverse effects?
Hypoglycemia
Hyperkalemia
Hyperglycemia
Hypokalemia
The Correct Answer is B
A. Hypoglycemia. Neither spironolactone nor lisinopril directly affects blood glucose levels. Hypoglycemia is more commonly associated with insulin, sulfonylureas (e.g., glipizide), and excessive alcohol consumption, rather than potassium-sparing diuretics or ACE inhibitors.
B. Hyperkalemia. Spironolactone is a potassium-sparing diuretic that promotes sodium excretion while retaining potassium, increasing the risk of hyperkalemia. Lisinopril, an ACE inhibitor, also raises potassium levels by reducing aldosterone secretion, which normally promotes potassium excretion. The combination of these two medications significantly increases the risk of dangerously high potassium levels, which can lead to cardiac arrhythmias, muscle weakness, and life-threatening complications. Clients should have serum potassium levels monitored regularly and be advised to avoid potassium-rich foods and supplements.
C. Hyperglycemia. Neither medication is known to cause hyperglycemia. Thiazide and loop diuretics are more likely to elevate blood glucose levels due to their effects on insulin sensitivity, but spironolactone and lisinopril do not share this effect.
D. Hypokalemia. Spironolactone prevents potassium loss, and lisinopril reduces potassium excretion, making hypokalemia unlikely. Hypokalemia is more commonly seen with loop diuretics (e.g., furosemide) and thiazide diuretics (e.g., hydrochlorothiazide), which promote potassium loss.

Correct Answer is B
Explanation
A. "Place a thick layer of the medication on open areas." Topical corticosteroids like fluticasone should not be applied in thick layers or to open wounds, as excessive absorption can lead to systemic side effects such as adrenal suppression. A thin layer is sufficient to achieve the desired anti-inflammatory effects while minimizing adverse reactions.
B. “Rub the medication until it disappears.” Topical corticosteroids should be applied in a thin layer and gently rubbed into the skin until no visible residue remains. This ensures even absorption without excessive medication buildup, reducing the risk of local and systemic side effects, especially in infants who have a higher risk of absorption due to their thinner skin.
C. "Cover the area with an occlusive dressing." Occlusive dressings increase medication absorption, which can lead to systemic corticosteroid effects such as skin thinning, delayed wound healing, and adrenal suppression. Occlusion should only be used under medical supervision, especially in infants who are more susceptible to these effects.
D. "Apply the medication to your infant's entire arm." Fluticasone should be applied only to affected areas, not the entire limb. Applying it over a larger area than necessary increases the risk of systemic absorption and side effects. The medication should be used only as directed for targeted treatment of atopic dermatitis.
Correct Answer is ["3"]
Explanation
Convert pounds to kilograms:
Conversion factor: 1 kg = 2.2 lb
66 lb / 2.2 lb/kg = 30 kg
Calculate the dose to administer:
Dose (mg) = Weight (kg) × Dosage (mg/kg)
=30 kg × 0.1 mg/kg
= 3 mg
