Simulated
A nurse is preparing to administer clindamycin by intermittent IV bolus over 30 minutes to a client who has a staphylococcal infection. Available is 300 mg clindamycin premixed in 50 mL 0.9% sodium chloride (NaCl). The nurse should set the IV pump to deliver how many mL/hr?
Correct answer
100
Rationale
The correct answer is 100 mL/hr. To calculate the rate, we first determine the total volume to be infused over 30 minutes (50 mL). Then, we convert 30 minutes to hours (0.5 hours). Finally, we divide the total volume by the time in hours (50 mL / 0.5 hr = 100 mL/hr). This rate ensures the clindamycin is administered safely and effectively. Other choices are incorrect because they do not align with the calculated infusion rate based on the medication concentration and administration time.
