A nurse is assisting with the care of a client who is in labor and is receiving penicillin G 5.000.000 units via intermittent IV bolus over 60 min. Available is penicillin G 5,000,000 units in 0.9% sodium chloride 100 mL. The nurse should ensure that the IV pump is set 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.)
