The nurse is caring for a client receiving a continuous infusion of heparin. The label reads 25,000 units of heparin in 500 mL of dextrose 5% in water (D5W). The client is receiving 1,500 units per hour. How many milliliters (mL) did the client receive in an eight-hour shift? Fill in the blank.
Correct Answer: 480 mL
Rationale: Calculate mL/hr: (1500 units/hr ÷ 25,000 units) × 500 mL = 30 mL/hr. For 8 hours: 30 mL/hr × 8 hr = 480 mL.

The nurse is caring for a client who is prescribed IV heparin. The client is prescribed 15 units/kg/hr. The client weighs 70 kgs (154 Ibs). The heparin is labeled with 25,000 units in 250 mL of D5W. How many mL/hr should this client receive? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 11 mL/hr
Rationale: Calculate dose: 15 units/kg/hr × 70 kg = 1050 units/hr. Flow rate: (1050 units/hr ÷ 25,000 units) × 250 mL = 10.5 mL/hr, rounded to 11 mL/hr.
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 primary healthcare provider (PHCP) prescribes amoxicillin 80 mg/kg/day to be given in two divided doses. The infant weighs 8.72 kg (19.18 Ibs). The label of the medication reads 250 mg/mL of amoxicillin. How many mL of amoxicillin should the nurse administer for one dose? Fill in the blank. Record your answer using 1 decimal place.
Correct Answer: 1.4 mL
Rationale: Calculate daily dose: 80 mg/kg × 8.72 kg = 697.6 mg. Per dose: 697.6 mg ÷ 2 = 348.8 mg. Convert: 348.8 mg ÷ 250 mg/mL = 1.3952 mL, rounded to 1.4 mL.
The primary healthcare provider (PHCP) prescribes a regular insulin infusion for a client with diabetic ketoacidosis (DKA). The prescription is for 2 units/hr. The label on the medication reads 250 mL of 0.9% saline containing 100 units of regular insulin. How many mL/hr should the client receive? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 5 mL/hr
Rationale: Calculate: (2 units/hr ÷ 100 units) × 250 mL = 5 mL/hr.
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.
