When caring for a patient who has been admitted for his heart failure, the nurse observes that the patient is experiencing bradycardia. Which drug should be administered to patients who develop bradycardia?

A. Antibiotics do not typically interact with adrenergic drugs in a way that would necessitate contacting the healthcare provider before administration.

B. MAO inhibitors can cause significant interactions with adrenergic drugs, potentially leading to hypertensive crises due to increased norepinephrine levels. Therefore, the nurse should contact the healthcare provider to assess the risks before administering an adrenergic agent.

C. Diuretics may affect fluid and electrolyte balance, but they do not pose a direct interaction risk with adrenergic drugs that would require prior consultation with the healthcare provider.

D. Analgesics do not have a significant interaction with adrenergic drugs that would warrant contacting the healthcare provider, as they are used for pain management and can often be safely administered together.

A. Changing positions slowly is critical for older adults taking beta-adrenergic blockers and diuretics to prevent orthostatic hypotension, which can lead to lightheadedness or dizziness.

B. Reducing fluid intake is not advisable, as thiazide diuretics can lead to dehydration, and maintaining adequate fluid intake is essential for overall health and to avoid excessive urinary output.

C. Identifying and eliminating high-potassium foods is unnecessary unless there is a specific indication of hyperkalemia, particularly since thiazide diuretics do not typically cause potassium retention, and beta-blockers are not potassium-specific.

D. Expecting blood pressure to increase before it decreases is misleading; clients should see a gradual reduction in blood pressure with proper medication adherence, and any sudden increases should be reported.
