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?

A.

Serum electrolyte levels

B.

Thyroid levels

C.

Coagulation studies

D.

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.

Correct Answer is D

Explanation

D. The expected therapeutic effect of montelukast is the reduction of bronchial inflammation. By blocking leukotriene receptors, montelukast helps to prevent the constriction of airway muscles, decrease mucus secretion, and reduce inflammation in the airways. This can lead to improved asthma control and symptom management.
A. Montelukast is not indicated for the treatment of gastric acid-related conditions such as gastroesophageal reflux disease (GERD) or peptic ulcers.
B. Montelukast is not typically associated with peripheral vasodilation. Its primary mechanism of action involves blocking the action of leukotrienes, which are inflammatory mediators involved in allergic and asthmatic reactions.
C. Montelukast does not affect white blood cell (WBC) count.

Correct Answer is C

Explanation

A. Nitroglycerin patches should not be removed for routine activities like bathing unless specifically instructed.
B. Nitroglycerin is used to treat hypertension, not induce it. Monitoring for hypertension after applying the patch is unnecessary.
C. To prevent skin irritation and tolerance to the medication, it is important to rotate the application sites when using a transdermal patch. This allows the skin to recover and helps maintain the effectiveness of the medication.
D. Nitroglycerin patches are typically worn continuously for 12 to 14 hours and then removed for a 10- to 12-hour nitrate-free interval to prevent tolerance to the medication.
