The Correct answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is C. Measure urinary output every hour<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Dopamine is a potent adrenergic agonist used primarily to increase blood pressure and cardiac output in patients who are hypotensive or in shock. It works by stimulating dopamine, beta-1, and alpha-adrenergic receptors, depending on the dosage, leading to increased heart rate, vasoconstriction, and improved renal perfusion.<\/p>\n\n\n\n

At moderate doses, like 8 mcg\/kg\/min, dopamine primarily stimulates beta-1 adrenergic receptors, which increase heart contractility and cardiac output. Additionally, it helps enhance renal perfusion by increasing blood flow to the kidneys, promoting urine output. This effect on the kidneys is critical when managing hypotensive clients, as low blood pressure can lead to decreased renal perfusion and, subsequently, acute kidney injury or renal failure.<\/p>\n\n\n\n

Why is hourly urinary output important?<\/h3>\n\n\n\n

Monitoring urinary output<\/strong> is one of the most reliable indicators of effective renal perfusion. By measuring it every hour, the nurse can assess whether the dopamine infusion is maintaining adequate blood flow to the kidneys. A urinary output of at least 30 mL\/hour is typically used as a marker of adequate kidney function and perfusion. A decrease in urine output could indicate worsening renal perfusion, signaling a need to adjust the dopamine dose or address underlying hemodynamic issues.<\/p>\n\n\n\n

Why not the other options?<\/h3>\n\n\n\n
    \n
  • A. Assess pupillary response to light hourly:<\/strong> While important for neurological assessments, pupillary response is not directly related to dopamine administration. This intervention is more relevant for clients with head trauma or neurological conditions.<\/li>\n\n\n\n
  • B. Initiate seizure precautions:<\/strong> Dopamine does not increase the risk of seizures. Seizure precautions are more relevant for clients with conditions like epilepsy, head injuries, or withdrawal from alcohol or drugs.<\/li>\n\n\n\n
  • D. Monitor serum potassium frequently:<\/strong> Dopamine administration does not directly affect potassium levels, so frequent monitoring of serum potassium is not necessary unless other medications or conditions require it.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
