Which information from a patient helps the nurse confirm the previous diagnosis of chronic stable angina?

Correct Answer: D

Rationale: The correct answer is D because relief of chest pain with nitroglycerin is a hallmark symptom of chronic stable angina. Nitroglycerin dilates blood vessels, improving blood flow to the heart, relieving chest pain. Choices A, B, and C do not specifically indicate typical angina symptoms like relief with nitroglycerin, which is crucial in confirming the diagnosis.

Correct Answer: A

Rationale: The correct answer is A: Generalized muscle aches and pains. This is the most important information to communicate because it could indicate a serious side effect known as rhabdomyolysis, a rare but severe condition that can be caused by statins (like pravastatin) and niacin. Rhabdomyolysis is characterized by muscle breakdown that can lead to kidney damage. It is crucial to monitor and address this symptom promptly. Choice B (Dizziness with rapid position changes) may be related to orthostatic hypotension, a common side effect of some medications but is not as urgent as potential rhabdomyolysis. Choice C (Nausea when taking the drugs before meals) is a common side effect of niacin and may be managed by adjusting the timing of medication administration. Choice D (Flushing and pruritus after taking the drugs) is a common side effect of niacin known as flushing and is generally not considered as serious as

Correct Answer: C

Rationale: The correct answer is C: Electrocardiogram (ECG). This should be arranged first because it provides immediate information on the patient's cardiac status, helping to determine if the chest pain is due to a heart-related issue like a myocardial infarction. A quick ECG can identify any acute changes in the heart's electrical activity. This is crucial for prompt intervention and treatment. Summary of other choices: A: Chest x-ray - While important for assessing lung and chest abnormalities, it does not provide immediate information on the patient's cardiac status. B: Troponin level - Useful for detecting myocardial damage, but results may take time to be available. Not as immediate as an ECG. D: Insertion of a peripheral IV - Important for administering medications and fluids, but not a priority over assessing the cardiac status in a patient with chest pain.

Correct Answer: C

Rationale: The correct answer is C: Monitor peripheral pulses. After cardiac catheterization, monitoring peripheral pulses is crucial to assess for any signs of complications such as decreased blood flow or vascular compromise. This intervention helps in early detection of potential issues and ensures prompt intervention if needed. A: Helping the client ambulate to the bathroom may be appropriate but monitoring peripheral pulses takes priority for assessing immediate complications post-cardiac catheterization. B: Fluid restriction is not indicated unless specifically prescribed by the healthcare provider. It is not a standard nursing intervention post-cardiac catheterization. D: Inserting an indwelling urinary catheter is not a priority intervention after cardiac catheterization unless there are specific indications such as monitoring urine output closely. Monitoring peripheral pulses takes precedence in this scenario.

Correct Answer: C

Rationale: The correct answer is C because an increase in pulmonary artery diastolic pressure indicates left-sided heart failure. In this scenario, the left side of the heart is unable to adequately pump blood to the rest of the body, causing an increase in pressure in the pulmonary circulation. This finding is consistent with the pathophysiology of left-sided heart failure. A: A drop in central venous pressure is more indicative of hypovolemia or right-sided heart failure. B: An increase in the cardiac index may suggest improved cardiac output, not specifically left-sided heart failure. D: A decline in mean pulmonary artery pressure is not a typical finding in left-sided heart failure.
