Question 1 of 5
A nurse is preparing to administer ampicillin/sulbactam 15 g via intermittent IV bolus, Available is ampicillin-sulbactam 1.5 g in 0.9% sodium chloride 100 mL to infuse over 30 min. The nurse should set the IV infusion pump to deliver how many mL/h?
Correct Answer: A
Rationale: The correct answer is A: 200 mL/h.
To calculate the infusion rate, you first need to convert the total dose of ampicillin/sulbactam to mL. The concentration is 1.5 g in 100 mL, so 15 g would be in 1000 mL. The infusion time is 30 min, so you need to convert it to hours (30 min รท 60 = 0.5 hours). Next, divide the total volume (1000 mL) by the infusion time (0.5 hours) to get 2000 mL/h.
Therefore, the nurse should set the IV pump to deliver 200 mL/h. Other choices are incorrect as they do not follow the correct calculations based on the given information.
