A nurse is preparing to administer oxytocin 3 milliunits/min via continuous IV infusion to a client for augmentation of labor.
Available is oxytocin 10 units in 0.9% sodium chloride 1,000 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.)
The Correct Answer is ["18"]
Step 1: Convert oxytocin units to milliunits 10 units × 1,000 milliunits/unit = 10,000 milliunits.
Step 2: Determine the concentration of oxytocin 10,000 milliunits ÷ 1,000 mL = 10 milliunits/mL.
Step 3: Calculate the flow rate (3 milliunits/min ÷ 10 milliunits/mL) × 60 min/hr = 18 mL/hr. Final Answer: 18 mL/hr.

Correct Answer is ["12.2"]
Explanation
Step 1: Convert newborn weight to kilograms 6.7 lb ÷ 2.2 lb/kg = 3.045 kg.
Step 2: Calculate the potassium dosage per hour 0.4 mEq/kg/hr × 3.045 kg = 1.218 mEq/hr.
Step 3: Calculate the infusion rate (1.218 mEq/hr ÷ 10 mEq) × 100 mL = 12.18 mL/hr. Final Answer: 12.2 mL/hr (rounded to the nearest tenth).
