A nurse in a provider's clinic is assessing a client who takes sublingual nitroglycerin for stable angina. The client reports getting a headache each time he takes the medication. Which of the following statements should the nurse make?
"Take only one dose of nitroglycerin to reduce the risk of getting a headache."
"We will ask the provider to prescribe a different medication for you."
"There's nothing that can be done to relieve the headaches that nitroglycerin causes."
"Try taking a mild analgesic to relieve the headache."
The Correct Answer is D
Choice A reason: Taking only one dose of nitroglycerin is not a good advice, as it may not be enough to relieve the angina pain and prevent a myocardial infarction. Nitroglycerin is a vasodilator that relaxes the blood vessels and improves the blood flow to the heart. The recommended dose is one tablet or spray under the tongue every 5 minutes for up to three doses, or until the pain is relieved. Taking only one dose may compromise the effectiveness of the medication and the safety of the client.
Choice B reason: Asking the provider to prescribe a different medication is not a necessary action, as nitroglycerin is a first-line treatment for stable angina and has proven benefits for reducing mortality and morbidity. Changing the medication may not be appropriate or feasible, as there may not be a suitable alternative that has the same efficacy and safety profile. The client should continue taking nitroglycerin as prescribed, unless the provider decides otherwise.
Choice C reason: Saying that there's nothing that can be done to relieve the headaches is not a true or helpful statement, as there are some measures that can help reduce or prevent the headaches. Headaches are a common and expected side effect of nitroglycerin, as it dilates the blood vessels in the brain and causes increased intracranial pressure. However, the headaches usually subside over time as the body adapts to the medication. The client can also take a mild analgesic, such as acetaminophen or ibuprofen, to relieve the headache, as long as it does not interact with the nitroglycerin or other medications.
Choice D reason: Trying to take a mild analgesic to relieve the headache is a reasonable and appropriate suggestion, as it can help alleviate the discomfort and improve the quality of life of the client. The client should choose an analgesic that is safe and effective, such as acetaminophen or ibuprofen, and follow the directions on the label. The client should also consult the provider or the pharmacist before taking any over-the-counter medications, as some of them may interact with nitroglycerin or other medications. The client should also avoid aspirin, as it may increase the risk of bleeding.

Correct Answer is D
Explanation
Choice A reason: The extra letters after the name of the medication do not mean it is a stronger dose, but that it is a combination of two different medications. Metoprolol is a beta-blocker that lowers blood pressure and heart rate, while hydrochlorothiazide is a diuretic that reduces fluid retention and blood volume. The combination of these two medications may have a synergistic effect and lower blood pressure more effectively than either one alone.
Choice B reason: The client will have to do some things differently because it is not the same medication, but a combination of two medications. The client will have to monitor their blood pressure, weight, fluid intake, and electrolyte levels more closely, as the addition of hydrochlorothiazide may increase the risk of dehydration, hypotension, and hypokalemia. The client will also have to avoid alcohol, salt, and potassium supplements, as they may interact with the medication and affect its efficacy or safety.
Choice C reason: The client will still have to diet to lose weight, as the medication does not cause weight loss, but may cause weight gain due to fluid retention. The client will have to follow a healthy diet that is low in sodium, fat, and cholesterol, as these may worsen hypertension and increase the risk of cardiovascular complications. The client will also have to exercise regularly, as this may help lower blood pressure and improve overall health.
Choice D reason: The client may experience fewer side effects with the new medication, as the combination of metoprolol and hydrochlorothiazide may lower the dose and frequency of each medication, and reduce the adverse effects of each one. For example, metoprolol may cause fatigue, dizziness, or bradycardia, while hydrochlorothiazide may cause dry mouth, headache, or gout. The combination of these two medications may balance out these effects and improve the client's tolerance and compliance.
Correct Answer is D
Explanation
Choice A reason: "Place one tablet under your tongue every 5 minutes for 30 minutes to relieve chest pain." is not the correct statement. This is an incorrect and potentially dangerous instruction, as it can cause overdose and severe hypotension. The nurse should instruct the client to place one tablet under the tongue at the first sign of chest pain, and repeat every 5 minutes for up to three doses, if needed. The client should call 911 if the pain is not relieved after the first dose.
Choice B reason: "Nitroglycerin decreases chest pain by dissolving blood clots that are occluding the arteries." is not the correct statement. This is a false and misleading explanation of how nitroglycerin works. Nitroglycerin does not dissolve blood clots, nor does it affect the occlusion of the arteries. Nitroglycerin is a vasodilator that relaxes the smooth muscle of the blood vessels, especially the veins. This reduces the preload and the oxygen demand of the heart, and relieves the chest pain caused by ischemia.
Choice C reason: "You can store the bottle of tablets in your bathroom medicine cabinet." is not the correct statement. This is an inappropriate and unsafe storage recommendation, as it can affect the potency and effectiveness of the medication. The nurse should instruct the client to store the bottle of tablets in a cool, dry, and dark place, away from heat, moisture, and light. The client should also keep the bottle tightly closed and replace it every 6 months, or as directed by the provider.
Choice D reason: "Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart." is the correct statement. This is a simple and accurate description of how nitroglycerin helps to relieve anginal pain. Nitroglycerin dilates the coronary arteries, which supply blood and oxygen to the heart muscle. This improves the blood flow and oxygen delivery to the ischemic areas of the heart, and reduces the pain and discomfort.
