A client has a medical prescription for nifedipine [Adalat XL]. Which of the following should the nurse teach the client about this medication?
A. “Swallow the medication whole and do not cut, crush, or chew the medication.”
B. “Take your blood pressure in the morning.”
C. “Use caution with over-the-counter (OTC) cold medications.”
D. “Take the medication before bedtime.”
The Correct answer and Explanation is:
The correct answer is A. “Swallow the medication whole and do not cut, crush, or chew the medication.”
Explanation:
Nifedipine, particularly in its extended-release formulation (such as Adalat XL), is a calcium channel blocker used primarily to manage hypertension and angina. The extended-release (XL) formulation is specifically designed to release the medication gradually over time, maintaining steady blood levels and minimizing fluctuations that can lead to side effects. Therefore, it is crucial that the client does not cut, crush, or chew the tablet, as doing so would disrupt the controlled release mechanism, potentially leading to an overdose and serious adverse effects.
B. “Take your blood pressure in the morning.”
While monitoring blood pressure is important for clients on antihypertensive medications, the timing suggested here is not necessarily optimal. Blood pressure can fluctuate throughout the day, and measuring it at various times, especially at peak times when medication levels are highest, can provide a more accurate representation of its effectiveness.
C. “Use caution with over-the-counter (OTC) cold medications.”
This statement is somewhat vague and could lead to confusion. While some OTC medications can affect blood pressure or interact with nifedipine, the nurse should provide specific examples of medications to avoid rather than a generalized caution.
D. “Take the medication before bedtime.”
Nifedipine can be taken at any time of day as directed by a healthcare provider. However, taking it at bedtime might not be suitable for all patients, especially if it can cause reflex tachycardia or might interfere with morning activities.
In summary, the most critical teaching point is to instruct the client to swallow the medication whole to ensure its intended therapeutic effect. This guidance helps prevent complications associated with improper administration of extended-release formulations.
