A nurse is assessing a client who has bradycardia. Which of the following findings should the nurse expect?

A. Auscultating heart tones can provide information about heart sounds, such as murmurs or rubs, but it is not the most effective method for diagnosing a myocardial infarction (MI).
B. Determining if the pain radiates to the left arm can help assess for MI, as pain radiating to the left arm is a common symptom of an MI. However, this alone is not sufficient to confirm the diagnosis.
C. A 12-lead ECG is the most definitive tool for diagnosing a myocardial infarction. It can detect changes in the heart's electrical activity that are characteristic of an MI, such as ST-segment elevation or depression.
D. Checking the client's blood pressure is important for overall assessment, but it is not specific for diagnosing a myocardial infarction. Blood pressure may be elevated or decreased in an MI, but it does not provide conclusive evidence of the condition.

A. A low-sodium diet is not appropriate for a child with Addison's disease. In fact, children with Addison's disease often require higher sodium intake due to the adrenal glands' inability to produce aldosterone, which regulates sodium balance.
B. Cortisol replacement therapy is essential for children with Addison's disease because the condition involves insufficient production of cortisol, a hormone vital for stress response and metabolism. Teaching parents about this therapy is a key nursing intervention to ensure proper management of the disease.
C. Hyperglycemia is not a primary concern in Addison's disease. In fact, the disease is more often associated with hypoglycemia due to low cortisol levels. Therefore, discussing hyperglycemia is not a priority in this case.
D. Fluid volume excess is not typically a concern in Addison's disease. In fact, due to aldosterone deficiency, patients are more prone to dehydration and hypotension, so monitoring for fluid volume deficit is more appropriate.
