A nurse is preparing to administer ampicillin 500 mg via intermittent IV bolus over 30 min. Available is 500 mg ampicillin in 50 mL dextrose 5% in water (DW). The nurse should set the 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.)

Question

A nurse is preparing to administer ampicillin 500 mg via intermittent IV bolus over 30 min. Available is 500 mg ampicillin in 50 mL dextrose 5% in water (DW). The nurse should set the 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.)

Answer 1

The nurse should set the pump to deliver 100 mL/hr.

Calculation:
500 mg/50 mL = 10 mg/mL
500 mg/30 min = 16.67 mg/min
16.67 mg/min * 60 min/hr = 1002 mg/hr
1002 mg/hr / 10 mg/mL = 100.2 mL/hr

Round to the nearest whole number = 100 mL/hr
