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.

Choice A: Straining all urine is not a relevant instruction for the nurse to provide, as this is not related to prostatitis. This is a distractor choice.

Choice B: Maintaining contact isolation is not a necessary instruction for the nurse to provide, as prostatitis is not a contagious condition. This is another distractor choice.

Choice C: Avoiding urinary catheterization is an important instruction for the nurse to provide, as this can introduce bacteria into the urinary tract and worsen the infection. Therefore, this is the correct choice.

Choice D: Restricting oral fluid intake is not an appropriate instruction for the nurse to provide, as this can lead to dehydration and reduced urine output, which can increase the risk of urinary stasis and infection. This is another distractor choice.
