A nurse is preparing to administer haloperidol 5 mg by IV bolus over 15 min. Available is haloperidol 5 mg in 50 mL dextrose 5% in water (D5W). 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 ["200"]
Step 1: Identify total volume and infusion time
Total volume = 50 mL
Infusion time = 15 minutes
Step 2: Use the formula for IV flow rate
Flow rate (mL/hr) = (Total volume ÷ Time in minutes) × 60
Flow rate = (50 ÷ 15) × 60
Flow rate ≈ 3.333 × 60 ≈ 200 mL/hr
Final Answer: 200 mL/hr
