The nurse is evaluating the effects of the prescribed carvedilol 6.25 mg PO daily for a client with a history of unstable angina. Which of the following reflects that the medication has been effective?

Choice A reason: The nurse should not encourage vigorous tooth brushing with a soft bristle toothbrush. Thrombocytopenia is a condition where the blood has a low number of platelets, which are cells that help with clotting. ¹ Vigorous tooth brushing can cause bleeding of the gums, which can be hard to stop in a client with thrombocytopenia. The nurse should advise the client to use a soft sponge or swab to clean the teeth and mouth gently.

Choice B reason: The nurse should avoid needle sticks or other invasive procedures as much as possible. Needle sticks and other invasive procedures can cause bleeding, bruising, or infection in a client with thrombocytopenia. ¹ The nurse should use the smallest gauge needle possible, apply pressure for at least 10 minutes after the procedure, and monitor the site for any signs of bleeding or infection. The nurse should also avoid unnecessary blood draws or injections, and use non-invasive methods whenever possible.

Choice C reason: The nurse should not hold all stool softeners and laxatives until otherwise ordered. Stool softeners and laxatives can help prevent constipation and straining, which can cause hemorrhoids or anal fissures in a client with thrombocytopenia. ¹ The nurse should encourage the client to take stool softeners and laxatives as prescribed, drink plenty of fluids, and eat high-fiber foods to promote regular bowel movements.

Choice D reason: The nurse should not obtain a low temperature every 8 hours. A low temperature is not a relevant or accurate measurement for a client with thrombocytopenia. The nurse should obtain a normal temperature, which is around 98.6°F (37°C), using a non-invasive method, such as an oral or tympanic thermometer. ² The nurse should avoid using a rectal thermometer, as it can cause bleeding or infection in a client with thrombocytopenia.

Choice A reason: Avoiding strenuous activity and standing up slowly is not a relevant response to the client's complaint of headache. These actions may help prevent or reduce orthostatic hypotension, which is another possible side effect of nitroglycerin, but not headache.

Choice B reason: Headache is expected and should subside with continued use is a correct and appropriate response to the client's complaint of headache. The nurse should explain that headache is a common and transient side effect of nitroglycerin, which is caused by the vasodilation effect of the drug. The nurse should also advise the client to take over-the-counter analgesics, such as acetaminophen, to relieve the headache.

Choice C reason: Reducing the dosage to help relieve this side effect is not a correct or appropriate response to the client's complaint of headache. The nurse should not suggest any changes in the prescribed dosage of nitroglycerin, as this may compromise the effectiveness of the drug and increase the risk of angina or myocardial infarction. The nurse should also remind the client to follow the instructions for applying and removing the Nitropatch.

Choice D reason: You will have this side effect as long as you are taking nitroglycerin is not a correct or appropriate response to the client's complaint of headache. The nurse should not discourage or alarm the client by implying that the headache is inevitable and permanent. The nurse should reassure the client that the headache will likely diminish over time as the body adapts to the drug.
