The nurse is caring for a client who has a prescription for heparin via continuous intravenous (IV) infusion at 60 units/kg/hr. The client weighs 85 kg (187 lb). The nurse has 25,000 units/250 mL on hand. How many mL/hr should the client receive? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 51 mL/hr
Rationale: Calculate dose: 60 units/kg/hr × 85 kg = 5100 units/hr. Flow rate: (5100 units/hr ÷ 25,000 units) × 250 mL = 51 mL/hr.

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.
A client with a stroke is prescribed alteplase. The prescription is for 0.9 mg/kg. The client weighs 116.82 kg (257 lbs). How many milligrams will the nurse administer? Fill in the blank. Record your answer to the nearest whole number.
Correct Answer: 105 mg
Rationale: Calculate dose: 0.9 mg/kg × 116.82 kg = 105.138 mg, rounded to 105 mg.
The nurse is calculating intake for a client. The client received: ,¢ One 100 mL intravenous antibiotic ,¢ One eight-ounce cup of ice chips ,¢ One eight-ounce cup of coffee ,¢ One eight-ounce cup of ice cream ,¢ Three eight-ounce cups of water. The nurse should calculate the client's total intake as how many mL? Fill in the blank.
Correct Answer: 1080 mL
Rationale: Convert ounces to mL: 8 oz = 240 mL. Ice chips count as half volume: 240 mL ÷ 2 = 120 mL. Total: 100 mL (antibiotic) + 120 mL (ice chips) + 240 mL (coffee) + 240 mL (ice cream) + 720 mL (3 cups water) = 1080 mL.
After receiving a bolus of intravenous (IV) fluids, the infant's diaper weighs 35 grams (after subtracting dry diaper weight). How many mL of urine should the nurse record in the medical record? Fill in the blank.
Correct Answer: 35 mL
Rationale: Urine weight in grams is equivalent to mL (1 g ≈ 1 mL for urine). Thus, 35 g = 35 mL.
The nurse is calculating intake for a client. The client received: 0.9% saline at 125 mL/hr for six hours three 8-ounce cups of cranberry juice,one 8-ounce cup of coffee,¢ one 8-ounce cup of water. How many mL should the nurse document as the client's total intake? Fill in the blank.
Correct Answer: 1680 mL
Rationale: Calculate IV fluid: 125 mL/hr × 6 hr = 750 mL. Convert ounces to mL: 8 oz = 240 mL. Total: 750 mL + 720 mL (3 cups juice) + 240 mL (coffee) + 240 mL (water) = 1680 mL.
