The nurse is teaching a client with hypertension about the prescribed hydrochlorothiazide 10 mg PO daily. Which statement, made by the client, would indicate that the teaching has been effective? "I will:

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.

Choice A reason: This is not an alarming statement. Feeling a little anxious when experiencing chest discomfort is a normal and understandable reaction. Chest discomfort can be a sign of angina, which is a condition where the heart muscle does not get enough oxygen due to reduced blood flow. Angina can cause pain, pressure, or tightness in the chest, and can be triggered by physical or emotional stress. The client should try to relax and take their medication as prescribed to relieve the discomfort.

Choice B reason: This is not an alarming statement. Knowing that they should carry their medication with them in case they develop chest pain is a sign of good self-care and awareness. The client should have a quick-relief medication, such as nitroglycerin, that can dilate the coronary arteries and improve the blood flow to the heart. The client should take the medication as soon as they feel chest pain and follow the instructions on how to use it.

Choice C reason: This is not an alarming statement. Learning to cook using the "good" cooking oils is a sign of positive lifestyle change and adaptation. The client should avoid or limit the intake of saturated and trans fats, which can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should use unsaturated fats, such as olive oil, canola oil, or sunflower oil, which can lower the LDL cholesterol and increase the high-density lipoprotein (HDL) cholesterol. HDL cholesterol is also known as the "good" cholesterol because it can remove the excess cholesterol from the arteries and transport it to the liver.

Choice D reason: This is the alarming statement. Waiting about two hours after feeling chest discomfort to seek medical attention is a sign of denial and delay. Chest discomfort can be a symptom of a heart attack, which is a life-threatening emergency where the blood flow to the heart is blocked and the heart muscle begins to die. The client should seek immediate medical attention if they experience chest pain that lasts more than a few minutes, or if it is accompanied by other signs, such as shortness of breath, nausea, sweating, or arm or jaw pain. The sooner the client receives treatment, the better the chance of survival and recovery.
