A nurse administered nitroglycerin sublingually to a client who has angina pectoris and experienced chest pain.
The client states that his chest pain is relieved but now he has a headache.
Which of the following responses by the nurse is appropriate?

Choice A rationale:

Taking hydrochlorothiazide on an empty stomach is not a requirement for this medication. Hydrochlorothiazide is a diuretic used to treat conditions like hypertension and edema. It can be taken with or without food, and food may help reduce stomach upset for some individuals.

Choice B rationale:

Muscle weakness is an adverse effect of hydrochlorothiazide. Therefore, it is not an expected outcome. Hydrochlorothiazide is a thiazide diuretic, and one of its common side effects is potassium loss through increased urine output. This can lead to muscle weakness and cramping. The nurse should educate the client about the signs and symptoms of low potassium and the importance of including potassium-rich foods in their diet.

Choice C rationale:

Increasing daily intake of foods high in potassium is essential information to include in the teaching for a client taking hydrochlorothiazide. Thiazide diuretics like hydrochlorothiazide can cause potassium depletion, which may result in adverse effects like muscle weakness, cramping, and cardiac dysrhythmias. Therefore, advising the client to consume potassium-rich foods, such as bananas, oranges, and potatoes, can help counteract the potassium loss associated with the medication.

Choice D rationale:

Taking the medication at bedtime is not a specific requirement for hydrochlorothiazide. Thiazide diuretics can be taken at various times of the day, depending on the client's preferences and when they are most compliant with their medication regimen. The timing of administration should be consistent to maintain the medication's effectiveness.

The correct answer is Choice A: Dull, aching calf pain.

Choice A rationale:

Dull, aching calf pain is a common symptom of deep vein thrombosis (DVT), which can occur postoperatively, especially after vascular surgery. This pain is often due to a blood clot forming in the deep veins of the leg.

Choice B rationale:

Positive Kernig's sign is associated with meningitis and not typically related to thrombus formation.

Choice C rationale:

Soft, pliable calf muscle is not indicative of a thrombus. A thrombus would more likely cause tenderness and swelling.

Choice D rationale:

Positive Homan's sign (pain in the calf upon dorsiflexion of the foot) can be an indicator of DVT, but it is less reliable than dull, aching calf pain.
