Question 1 of 5
A nurse is preparing to administer clindamycin 300 mg by intermittent IV bolus over 30 min to a client who has a staphylococci infection. Available is clindamycin premixed in 50 mL 0.90% sodium chloride (NaCl). 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.)
Correct Answer: A
Rationale: The correct answer is A: 100 mL/hr.
To calculate the rate, first convert 30 minutes to hours (30 min ÷ 60 min = 0.5 hrs).
Then, divide the total volume (50 mL) by the time (0.5 hrs) to get the rate in mL/hr (50 mL ÷ 0.5 hrs = 100 mL/hr). This rate ensures the clindamycin is delivered over 30 minutes as prescribed. Other choices are incorrect as they do not reflect the correct calculation for the infusion rate.
