A nurse is teaching a client who has a new prescription for a nitroglycerin transdermal patch.
Which of the following instructions should the nurse include?
Apply a new patch if you have chest pain.
Discontinue the patch if you experience a headache.
Remove the patch prior to going to bed.
Cover the patch with dry gauze when taking a shower.
The Correct Answer is C
Nitroglycerin transdermal patches are used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart). They work by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen.
Choice A is wrong because nitroglycerin transdermal patches cannot be used to treat an attack of angina once it has begun. They can only be used to prevent attacks of angina. If you have chest pain, you should use another form of nitroglycerin, such as sublingual tablets or spray.
Choice B is wrong because headache is a common side effect of nitroglycerin transdermal patches and does not mean that you should stop using them. However, you should tell your doctor if the headaches are severe or do not go away. You may also take acetaminophen to relieve the headache.
Choice D is wrong because you do not need to cover the patch with dry gauze when taking a shower. You may shower while you are wearing a nitroglycerin skin patch. If a patch loosens or falls off, replace it with a fresh one.
