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?

Client reports tightness in chest that radiates to left arm: Chest tightness that radiates to the left arm is a classic symptom of myocardial ischemia or infarction (heart attack). This symptom is concerning because it suggests potential heart muscle damage or decreased blood flow to the heart.

States pain as 7 on a scale of 0 to 10: The client rates their chest pain as 7 out of 10. This indicates significant discomfort and suggests that the chest tightness is causing substantial pain. Pain severity is an important indicator in assessing the severity of the cardiac event.

Started to feel nauseous after breakfast: Nausea can be a symptom associated with myocardial ischemia or infarction, particularly when it occurs after physical exertion or a meal. It can be caused by decreased blood flow to the gastrointestinal tract due to compromised cardiac function.

Client is diaphoretic and short of breath: Diaphoresis (excessive sweating) and shortness of breath are additional symptoms that commonly accompany acute myocardial infarction. Diaphoresis occurs due to sympathetic nervous system activation, while shortness of breath can result from decreased cardiac output or pulmonary congestion.

Heart rate irregular and tachycardic: An irregular and tachycardic (rapid) heart rate is abnormal and suggests cardiac dysrhythmia, which can occur in response to myocardial ischemia or infarction. It reflects the heart's attempt to compensate for reduced oxygen delivery to the body.

The nurse should first address the client pain level followed by the client's ECG results

Rationale

Pain level: Addressing the client's pain level is crucial because it directly affects their comfort and can be indicative of ongoing myocardial ischemia or infarction. The client initially reported chest pain as 7/10, which is significant. Although it has decreased to 5/10 after nitroglycerin, ongoing assessment of pain is essential to ensure it does not worsen or change in nature.

ECG results: The 12-lead electrocardiogram (ECG) shows tachycardia with ST segment elevation and T wave changes. These findings indicate acute myocardial ischemia or infarction, which is a critical concern. The ECG results guide further diagnosis and treatment decisions, such as determining the need for immediate reperfusion therapy (like thrombolytics or angioplasty).
