A client who is hypotensive is receiving dopamine, an adrenergic agonist, IV at the rate of 8 mcg/kg/min. Which intervention should the nurse implement while administering this medication?

Choice A: Assessing pupillary response to light hourly is not related to dopamine administration. Dopamine does not affect the pupils or the cranial nerves that control them. Choice B: Initiating seizure precautions is not necessary for a client receiving dopamine. Dopamine does not lower the seizure threshold or cause convulsions. Choice C: Measuring urinary output every hour is an important intervention for a client receiving dopamine. Dopamine increases blood pressure and cardiac output, which improves renal perfusion and urine production. Urinary output is an indicator of the effectiveness of dopamine therapy and renal function. Choice D: Monitoring serum potassium frequently is not directly related to dopamine administration. Dopamine does not affect potassium levels or cause hyperkalemia or hypokalemia. However, potassium levels may be affected by other factors such as fluid balance, renal function, and medications.
