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?

Exertional dyspnea resolved

Heart rate 50 beats/minute

Heart rhythm regular

Blood pressure 120/90

Answer and Explanation

The Correct Answer is A

Choice A reason: Exertional dyspnea is a common symptom of unstable angina, which is caused by reduced blood flow to the heart muscle. Carvedilol is a beta-blocker that reduces the workload of the heart and improves its oxygen supply. Therefore, resolving exertional dyspnea indicates that the medication has been effective.

Choice B reason: A heart rate of 50 beats/minute is not a desired outcome of carvedilol therapy. It may indicate that the dose is too high or that the client has a conduction problem. A normal resting heart rate for adults is between 60 and 100 beats/minute.

Choice C reason: A regular heart rhythm is not a specific indicator of carvedilol effectiveness. Carvedilol can prevent or treat some arrhythmias, but it is not the primary goal of therapy for unstable angina. A regular heart rhythm may also be influenced by other factors such as electrolytes, hydration, and stress.

Choice D reason: A blood pressure of 120/90 is not a sign of carvedilol effectiveness. Carvedilol can lower blood pressure, but it is not the main purpose of treatment for unstable angina. A blood pressure of 120/90 is considered prehypertension, which may increase the risk of cardiovascular complications.

Correct Answer is C

Explanation

Choice A reason: This option is not correct because the cholesterol level is within the normal range of less than 200 mg/dL¹, the HDL level is slightly low but not too far from the recommended level of over 40 mg/dL for men and over 50 mg/dL for women¹, and the triglyceride level is also within the normal range of less than 150 mg/dL¹. Therefore, this set of laboratory results does not indicate a need for dietary modifications.

Choice B reason: This option is not correct because the cholesterol level is low, the HDL level is high, and the triglyceride level is normal. These are all desirable results that reflect a low risk of coronary artery disease¹. Therefore, this set of laboratory results does not indicate a need for dietary modifications.

Choice C reason: This option is correct because the cholesterol level is high, the HDL level is low, and the triglyceride level is high. These are all unfavorable results that reflect a high risk of coronary artery disease¹. High cholesterol and triglycerides can lead to plaque buildup in the arteries, which can cause atherosclerosis and reduce blood flow to the heart². Low HDL can also increase the risk of heart disease because it does not help remove LDL (bad cholesterol) from the arteries². Therefore, this set of laboratory results indicates a need for dietary modifications, such as reducing saturated and trans fats, increasing fiber, and limiting alcohol³.

Choice D reason: This option is not correct because the cholesterol level is normal, the HDL level is high, and the triglyceride level is normal. These are all desirable results that reflect a low risk of coronary artery disease¹. Therefore, this set of laboratory results does not indicate a need for dietary modifications..

A. Furosemide 40 mg PO daily B. Diltiazem 30 mg PO daily C. Metoprolol 25 mg PO bid D. Nitroglycerin 0.4 mg SL PRN

Correct Answer is D

Explanation

Choice A reason: Furosemide 40 mg PO daily is not the medication that the nurse should administer for chest pain. Furosemide is a diuretic that reduces fluid volume and lowers blood pressure, but it does not relieve anginal pain.

Choice B reason: Diltiazem 30 mg PO daily is not the medication that the nurse should administer for chest pain. Diltiazem is a calcium channel blocker that relaxes the blood vessels and lowers blood pressure, but it does not act quickly enough to relieve acute anginal pain.

Choice C reason: Metoprolol 25 mg PO bid is not the medication that the nurse should administer for chest pain. Metoprolol is a beta blocker that slows down the heart rate and lowers blood pressure, but it does not act quickly enough to relieve acute anginal pain.

Choice D reason: Nitroglycerin 0.4 mg SL PRN is the medication that the nurse should administer for chest pain. Nitroglycerin is a nitrate that dilates the coronary arteries and increases blood flow to the heart, thus relieving anginal pain. It is given sublingually (under the tongue) as needed for chest pain.
