A nurse is caring for a client who has hypertension and has been taking hydrochlorothiazide. Which of the following laboratory values should the nurse evaluate?

Serum electrolyte levels

Thyroid levels

Coagulation studies

Complete blood count

Answer and Explanation

The Correct Answer is A

A.   Hydrochlorothiazide can cause electrolyte imbalances, particularly hypokalemia (low potassium levels), hyponatremia (low sodium levels), and hypomagnesemia (low magnesium levels). Monitoring serum electrolyte levels, including potassium, sodium, and magnesium, is essential to detect and manage any abnormalities that may occur as a result of hydrochlorothiazide therapy.
B.   Thyroid levels are not typically affected by hydrochlorothiazide therapy. Therefore, monitoring thyroid levels is not necessary in clients taking hydrochlorothiazide for hypertension.
C.   Hydrochlorothiazide is not known to affect coagulation studies such as prothrombin time (PT), activated partial thromboplastin time (aPTT), or international normalized ratio (INR).
D.   Hydrochlorothiazide is not typically associated with significant hematologic effects that would necessitate routine monitoring of the complete blood count. Therefore, monitoring CBC is not routinely indicated for clients taking hydrochlorothiazide for hypertension.

Explanation

A. Sitting upright after taking the medication is not a standard recommendation.
B. Sustained-release verapamil tablets should not be crushed, chewed, or broken. Crushing a sustained- release tablet can disrupt the extended-release mechanism, leading to an immediate release of the entire dose, which can increase the risk of adverse effects and toxicity.
C. While monitoring is essential for some medications, anemia is not a specific concern related to sustained-release verapamil.
D. Verapamil has been reported to cause constipation as a side effect. This is one of the most commonly reported side effects of verapamil. It is suggested that this effect may be due to a delay in colonic transit.
