A nurse is reviewing the lab work of a client on a medical-surgical unit who has a new prescription for captopril. Which of the following laboratory values should the nurse identify as the priority to monitor?

Alanine aminotransferase

Thyroid-stimulating hormone

Potassium

Magnesium

Answer and Explanation

The Correct Answer is C

A. Monitoring alanine aminotransferase is important for liver function, but it is not the priority for a client on captopril.

B. Thyroid-stimulating hormone is not directly impacted by captopril and is not the priority lab value to monitor in this context.

C. Potassium is the priority laboratory value to monitor because captopril, an ACE inhibitor, can lead to hyperkalemia (elevated potassium levels), which can cause serious cardiac complications.

D. While magnesium levels are important to monitor, they are not specifically related to captopril therapy as potassium levels are.

Correct Answer is D

Explanation

A. Lactated Ringer's: This solution is isotonic and is typically used for fluid resuscitation, not for hypotonic treatment.

B. 0.9% sodium chloride: This is isotonic saline and does not qualify as a hypotonic solution.

C. 3% sodium chloride: This solution is hypertonic and used to treat severe hyponatremia, not hypotonic hydration.

D. 0.45% sodium chloride: This is the correct choice as it is a hypotonic solution that can help to hydrate cells by providing free water.

A. "Remove the patch for two to four hours daily." B. "Apply a new patch each day after waking up." C. "Cover the patch with plastic wrap." D. "Replace the existing patch with a new patch as soon as anginal pain begins."

Correct Answer is B

Explanation

A. "Remove the patch for two to four hours daily.": This is incorrect because transdermal nitroglycerin patches should be worn continuously for 24 hours, with a scheduled time to remove them (usually overnight) to prevent tolerance.

B. "Apply a new patch each day after waking up.": This instruction is correct; clients should apply a new patch daily to ensure continuous therapeutic effects while also allowing a break to reduce tolerance.

C. "Cover the patch with plastic wrap.": This is incorrect; covering the patch with plastic wrap can alter the absorption of the medication and is not necessary.

D. "Replace the existing patch with a new patch as soon as anginal pain begins.": This is incorrect; clients should not replace the patch immediately for angina. Instead, they should use sublingual nitroglycerin for immediate relief and follow the prescribed patch schedule.
