Administer Dopamine 3 mcg/kg/min. The client weighs 176 pounds. The drug is available as 500 mg in 250 mL of fluid. Calculate mcg/min, mcg/hr, and mL/hr. (Do not round your answer and include unit of measure with each answer)
The Correct Answer is ["7.2"]
Dopamine infusion calculation:
- Client weight: 176 pounds
- Dopamine dose ordered: 3 mcg/kg/min
- Dopamine concentration: 500 mg in 250 mL
- Conversion factor: 1 mg = 1000 mcg
- 1 kg = 2.2 pounds
Calculations:
- Convert client weight to kg: 176 lbs / 2.2 lbs/kg = 80 kg
- Calculate mcg/min: 3 mcg/kg/min × 80 kg = 240 mcg/min
- Calculate mcg/hr: 240 mcg/min × 60 min/hr = 14400 mcg/hr
- Calculate mL/hr: Dopamine concentration is 2 mg/250 mL, which equals 2000 mcg/mL.
- mL/hr = 14400 mcg/hr / 2000 mcg/mL = 7.2 mL/hr
Answers:
- mcg/min: 240 mcg/min
- mcg/hr: 14400 mcg/hr
- mL/hr: 7.2 mL/hr

Correct Answer is C
Explanation
A. "Exposure to sunlight will help to strengthen your eyes.": Sunlight exposure is not recommended as it can exacerbate symptoms.
B. "These are unusual symptoms. I will ask the provider for an ophthalmology referral.": These symptoms are characteristic of Graves' ophthalmopathy and do not require an immediate referral unless severe.
C. "Eye drops and dim lighting can improve your symptoms." These interventions can help alleviate discomfort associated with dryness and light sensitivity in hyperthyroidism-related eye changes (Graves' ophthalmopathy).
