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.

Correct Answer is D
Explanation
This site is preferred for peripheral IV catheter placement because it is comfortable, has good blood flow, and has a lower risk of complications than the dominant arm or the antecubital fossa.
Choice A is wrong because the dominant antecubital basilic vein is more prone to dislodgement, thrombosis, and thrombophlebitis due to frequent movement of the elbow joint.
Choice B is wrong because the nondominant dorsal venous arch is a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.
Choice C is wrong because the dominant distal dorsal vein is also a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.
Correct Answer is D
Explanation
Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease1 and should be used with caution in patients with hepatic impairment or active liver disease. Alcohol use disorder can cause liver damage and increase the risk of acetaminophen toxicity.
Choice A is wrong because hepatitis B vaccine within the last week is not a contraindication for receiving acetaminophen.
There is no evidence that acetaminophen interferes with the immune response to the vaccine or causes adverse effects.
Choice B is wrong because chronic kidney disease is not a contraindication for receiving acetaminophen.
Acetaminophen is mainly metabolized by the liver and has minimal renal excretion.
However, patients with chronic kidney disease should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
Choice C is wrong because diabetes mellitus is not a contraindication for receiving acetaminophen.
Acetaminophen does not affect blood glucose levels or interact with oral antidiabetic drugs.
However, patients with diabetes mellitus should consult their doctor before taking acetaminophen as they may have other conditions that affect its use.
