A nurse is providing teaching to a client and his partner about performing peritoneal dialysis at home. When discussing peritonitis, which of the following manifestations should the nurse identify as the earliest indication of this complication?

A. The client presents with symptoms and signs suggestive of acute coronary syndrome, including chest pain, tachycardia, and ECG changes (ST segment elevation and T wave changes). Elevated troponin levels indicate myocardial injury. Cardiac catheterization is typically indicated in acute coronary syndrome to assess coronary artery anatomy and potentially perform interventions like angioplasty or stenting to restore blood flow to the heart muscle.
B. Continuous heparin infusion is commonly used in the management of acute coronary syndrome to prevent further clot formation and stabilize the condition. It helps in reducing the risk of thrombus formation in the coronary arteries, which is crucial in cases of myocardial infarction.
C. Ambulation is generally not recommended during the acute phase of myocardial infarction or unstable angina. The client's symptoms, such as chest pain, shortness of breath, and diaphoresis, indicate ongoing cardiac compromise. Ambulation could potentially worsen the client's condition or lead to adverse events.
D. Metoprolol is a beta-blocker used to reduce heart rate, blood pressure, and myocardial oxygen demand. While it is indicated in acute coronary syndrome to stabilize heart rate and reduce myocardial ischemia, increasing the dosage should be done cautiously and based on the client's response to initial therapy.
E. NPO status is typically indicated for clients undergoing procedures that require sedation or anesthesia, such as cardiac catheterization. It ensures the client's stomach is empty to reduce the risk of aspiration during the procedure. Given the potential need for cardiac catheterization in this client, obtaining a prescription for NPO status would be appropriate to prepare for the procedure and ensure safety.
F. Antibiotics are not routinely indicated in the management of acute coronary syndrome unless there is evidence of concomitant infection or specific clinical indications (e.g., pneumonia). In the absence of signs or symptoms of infection, requesting an antibiotic prescription is not warranted based on the client's current presentation.

A Nitroglycerin is a vasodilator that helps relieve angina by dilating blood vessels and increasing blood flow to the heart muscle. It is typically the first-line medication for acute angina attacks. Administering nitroglycerin promptly can help alleviate the client's pain and prevent progression to a myocardial infarction (heart attack).

B. Aspirin is often administered to clients with suspected myocardial ischemia or infarction because it inhibits platelet aggregation, which can reduce the risk of clot formation and further occlusion of coronary arteries. It is typically given early in the management of acute coronary syndrome to prevent clotting complications.

C. While monitoring blood pressure is important in clients with acute angina, especially to assess for hypotension which could indicate cardiogenic shock, it is not the first action. Immediate pain relief and prevention of further ischemic damage take precedence over blood pressure measurement.

D. IV access is important for administering medications and fluids if needed, but it is not the first priority unless the client's condition warrants immediate IV medication administration (such as in severe pain or impending myocardial infarction).
