A nurse is teaching a client who has a new diagnosis of venous insufficiency. Which of the following instructions should the nurse include?

Nitroglycerin is a vasodilator that relaxes smooth muscle in blood vessels and reduces myocardial oxygen demand. It is used to treat and prevent angina atacks. A common side effect of nitroglycerin is headache, which is caused by cerebral vasodilation. The nurse should advise the client to take a mild analgesic, such as acetaminophen, to relieve the headache. The headache usually subsides with continued use of nitroglycerin.

The other options are not correct because:

"Take only one dose of nitroglycerin to reduce the risk of getting a headache." This statement is incorrect because it may compromise the effectiveness of nitroglycerin in relieving angina. The client should follow the prescribed dosage and frequency of nitroglycerin, which is usually one tablet every 5 minutes for up to three doses, as needed for chest pain.

"There's nothing that can be done to relieve the headaches that nitroglycerin causes." This statement is incorrect because it is discouraging and dismissive of the client's concern. The nurse should acknowledge the client's

discomfort and offer suggestions for managing the side effect, such as taking a mild analgesic or lying down in a dark room.

"We will ask the provider to prescribe a different medication for you." This statement is incorrect because it implies that nitroglycerin is not suitable for the client and may cause unnecessary anxiety or confusion. The nurse should explain that nitroglycerin is an effective and safe medication for angina and that the headache is a common and transient side effect that can be managed with simple measures. The nurse should also inform the client that there are other forms of nitroglycerin, such as patches or sprays, that may have less headache-inducing effects. However, changing the medication or the route of administration should be done only after consulting with the provider.

The nurse should instruct the client to adjust the thermostat so that the environment is warm because cold temperatures can cause vasoconstriction and worsen the symptoms of PAD, such as pain, numbness, and poor wound healing. The client should also avoid exposure to cold weather and wear warm clothing.

1. Apply a heating pad on a low setting to help relieve leg pain is wrong because it can cause burns, vasodilation, and increased blood flow to the legs, which can increase the risk of bleeding and edema in PAD.
2. Wear antiembolic stockings during the day is wrong because they can impair arterial circulation and cause ischemia and tissue damage in PAD. Antiembolic stockings are used to prevent venous thromboembolism, not arterial disease.

Rest with the legs above heart level is wrong because it can decrease arterial blood flow to the legs and worsen ischemia and pain in PAD. The client should rest with the legs at or below heart level to promote arterial circulation.
