The nurse is caring for a client prescribed IV heparin. The client is prescribed 15 units/kg/hr. The client weighs 115.9 kg (254.8 lbs). 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. Record your answer using a whole number.
Correct Answer: 17 mL/hr
Rationale: Calculate dose: 15 units/kg/hr × 115.9 kg = 1738.5 units/hr. Flow rate: (1738.5 units/hr ÷ 25,000 units) × 250 mL = 17.39 mL/hr, rounded to 17 mL/hr.

The primary healthcare provider (PHCP) prescribes lidocaine at 2 mg/min. The medication label reads lidocaine 1 gram in 500 mL of 0.9% saline. How many mL per hour will the nurse administer to the client? Fill in the blank.
Correct Answer: 60 mL/hr
Rationale: Convert: 1 g = 1000 mg, so 1000 mg/500 mL = 2 mg/mL. Flow rate: (2 mg/min ÷ 2 mg/mL) × 60 min/hr = 60 mL/hr.
The nurse is calculating intake for a client for the previous twelve-hour shift. The client received: ,¢ One 150 mL intravenous antibiotic ,¢ One eight-ounce cup of coffee ,¢ One eight-ounce cup of ice cream ,¢ Three eight-ounce cups of water ,¢ Two 10 mL sodium chloride (normal saline) flushes. The nurse should calculate the client's total intake as how many mL? Fill in the blank.
Correct Answer: 1130 mL
Rationale: Convert ounces to mL: 8 oz = 240 mL. Total: 150 mL (antibiotic) + 240 mL (coffee) + 240 mL (ice cream) + 720 mL (3 cups water) + 20 mL (flushes) = 1130 mL.
The nurse is preparing to administer a regular insulin IV bolus to a client who has hyperglycemic-hyperosmolar state (HHS). The primary health care provider (PHCP) has prescribed an initial bolus dose of 0.1 unit/kg. The client weighs 125.90 kg (276.98 lbs). How much regular insulin should the nurse administer to the client as an IV bolus? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 13 units
Rationale: Calculate: 0.1 units/kg × 125.90 kg = 12.59 units, rounded to 13 units.
The primary healthcare provider orders methylprednisolone 1.6 mg/kg for a child weighing 30.4 kg (66.8 lbs). The label on the medication reads 500 mg/4 mL. How many milliliters (mL) should the nurse administer? Fill in the blank. Round your answer using 1 decimal place.
Correct Answer: 0.4 mL
Rationale: Calculate dose: 1.6 mg/kg × 30.4 kg = 48.64 mg. Convert: (48.64 mg ÷ 500 mg) × 4 mL = 0.39 mL, rounded to 0.4 mL.
The nurse is calculating the 12-hour intake for a client. The client received: ,¢ 0.45% saline at 85 mL/hr via continuous infusion ,¢ 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 ,¢ One eight-ounce cup of pureed vegetables. The nurse should calculate the client's total liquid intake as how many mL? Fill in the blank.
Correct Answer: 1770 mL
Rationale: Calculate IV fluid: 85 mL/hr × 12 hr = 1020 mL. Each 8-ounce cup = 240 mL (since 1 oz ≈ 30 mL). Ice chips count as half volume: 240 mL ÷ 2 = 120 mL. Total: 1020 mL + 120 mL (ice chips) + 240 mL (coffee) + 240 mL (ice cream) + 720 mL (3 cups water) + 240 mL (vegetables) = 1770 mL.
