The nurse identifies that a patient with chronic kidney disease is at risk for which electrolyte disturbance?

Based on the client's condition, the nurse should monitor the following:

C. Electrocardiogram (ECG) Rhythm: The client is experiencing chest pain with ST elevation, which indicates a possible myocardial infarction (MI). Continuous monitoring of the ECG rhythm is essential to identify any changes or dysrhythmias that may occur during the course of the client's care.

E. Vital signs: The client's tachycardia with ST elevation suggests cardiac involvement. Monitoring vital signs, including heart rate, blood pressure, respiratory rate, and oxygen saturation, is crucial to assess the client's hemodynamic status and detect any signs of deterioration or improvement.

The other options (A. WBC Count, B. Platelet Count, and D. Serum glucose level) are not directly related to the client's acute chest pain and the possible MI. While these tests may be ordered for other reasons or as part of the overall assessment, they are not the immediate priorities in this situation. Monitoring the ECG rhythm and vital signs are more relevant to the client's acute cardiac condition.

This statement indicates effective learning because serum cardiac markers are indeed proteins that are released from necrotic (damaged) heart muscle cells when there is myocardial injury, such as in acute coronary syndrome (ACS). These markers are measured in blood tests and help in the diagnosis and assessment of ACS, particularly myocardial infarction (heart attack).

Option A is incorrect because a nitroprusside stress echocardiogram is not used for acute pericarditis. It is a diagnostic test used for evaluating coronary artery disease and ischemia.

Option B is incorrect because a pathologic Q wave is not always present in the electrocardiogram (ECG) of patients with unstable angina. It is a characteristic finding in the ECG of patients with a previous myocardial infarction (heart attack) but may not be present in unstable angina.

Option D is incorrect because coronary angiography is not the only way to confirm the diagnosis of unstable angina. Unstable angina is primarily diagnosed based on the clinical presentation, symptoms, and changes in the ECG. Coronary angiography is an invasive procedure used to visualize the coronary arteries directly and is typically reserved for cases where further assessment and intervention are needed, such as in cases of suspected coronary artery disease.
