The nurse is reinforcing teaching for a patient with chronic heart failure. Which of the following weight measurements should the nurse ask the patient to perform to monitor fluid status at home?

Choice A reason: Anginal pain typically does not worsen with deep inspiration; this is more characteristic of pleuritic chest pain.

Choice B reason: Anginal pain usually does not persist with rest and organic nitrates; these interventions are typically used to alleviate angina.

Choice C reason: Exertion and anxiety increase the heart's demand for oxygen, which can trigger anginal pain due to reduced blood flow in narrowed coronary arteries.

Choice D reason: Anginal pain typically lasts for a short time, usually less than 20 minutes. If the pain lasts longer, it may indicate a more serious condition like a myocardial infarction.

Choice A reason: An exercise stress test can help diagnose coronary artery disease by measuring the heart's ability to respond to external stress in a controlled clinical environment.

Choice B reason: Troponin I is a blood test that measures the levels of troponin T or troponin I proteins in the blood. These proteins are released when the heart muscle has been damaged, such as in a heart attack, which is a common complication of coronary artery disease.

Choice C reason: Cardiac computed tomography (CT) for calcium scoring is a non-invasive way of obtaining information about the presence, location, and extent of calcified plaque in the coronary arteries.

Choice D reason: Radioisotope imaging, such as a nuclear stress test, can show how blood moves to the heart muscle at rest and during stress, helping to diagnose coronary artery disease.

Choice E reason: Angiography involves using X-rays to see your body's blood vessels. Coronary angiography is specifically used to see if your coronary arteries are blocked or narrowed, where they supply blood to your heart.
