The nurse is calculating intake for a client. The client received: ,¢ 0.9% saline at 70 mL/hr for four hours ,¢ two eight-ounce cups of ice chips ,¢ one eight-ounce cup of coffee ,¢ three eight-ounce cups of water.

The primary healthcare provider (PHCP) prescribes dopamine at 2.5 mcg/kg/minute. The client weighs 90 kg (198 lbs). The medication label reads dopamine 800 mg in 500 mL of dextrose 5% water (D5W). How many mL per hour will be administered to the client? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 8 mL/hr
Rationale: Calculate dose: 2.5 mcg/kg/min × 90 kg = 225 mcg/min. Convert: 800 mg = 800,000 mcg, so 800,000 mcg/500 mL = 1600 mcg/mL. Flow rate: (225 mcg/min ÷ 1600 mcg/mL) × 60 min/hr = 8.44 mL/hr, rounded to 8 mL/hr.
