A nurse is providing teaching to a client who has stable angina and a new prescription for nitroglycerin oral, sustained-release capsules. Which of the following instructions should the nurse include?
A.
Take 1 capsule at the onset of anginal pain.
B.
Take the medication with meals.
C.
Swallow the capsules whole.
D.
Stop taking the medication if side effects are troublesome.
The correct answer and Explanation is :
The correct instruction for the client with stable angina who has a new prescription for nitroglycerin oral, sustained-release capsules is:
C. Swallow the capsules whole.
Explanation:
Nitroglycerin oral, sustained-release capsules are designed to release the medication slowly over time, providing a consistent level of nitroglycerin in the bloodstream to help prevent anginal episodes. The proper administration of this medication is crucial for its effectiveness and to avoid potential side effects.
Swallow the capsules whole: Sustained-release capsules must be swallowed whole to ensure that the nitroglycerin is released gradually into the system. Crushing or chewing the capsules can destroy the sustained-release mechanism, leading to a rapid release of the medication, which can cause an unintended peak in drug levels and potentially increase the risk of side effects or reduce the medication’s efficacy.
Why not the other options?
- A. Take 1 capsule at the onset of anginal pain: This instruction is not applicable for sustained-release capsules. Nitroglycerin oral, sustained-release capsules are intended for long-term prevention of angina rather than for immediate relief of acute anginal pain. For acute episodes of angina, sublingual nitroglycerin tablets are typically used.
- B. Take the medication with meals: Sustained-release nitroglycerin capsules can be taken with or without food. There is no specific requirement for taking them with meals, although some medications can have altered absorption with food. For nitroglycerin, the primary concern is to ensure the capsule is swallowed whole.
- D. Stop taking the medication if side effects are troublesome: It is important for clients to consult their healthcare provider before discontinuing any medication, including nitroglycerin. Stopping medication abruptly without medical advice can lead to uncontrolled angina and other complications. If side effects occur, they should be discussed with a healthcare provider who can provide guidance on how to manage them or adjust the treatment as necessary.
By following the proper administration guidelines, the client can maximize the benefits of the medication while minimizing potential risks and side effects.
