Question 1 of 5
A nurse is preparing to administer gentamicin 200 mg infusion over 1 hr to a child. Available is gentamicin 200 mg in 100 mL of 0.9% sodium chloride solution. The nurse should set the IV pump to deliver how many mL per hour?
Correct Answer: A
Rationale: The correct answer is A: 100 mL/hr.
To administer gentamicin 200 mg over 1 hour, the nurse must infuse the entire 100 mL solution.
Therefore, the IV pump should be set to deliver the entire 100 mL over 1 hour, which equals 100 mL/hr. This calculation ensures the correct dose of gentamicin is given within the specified time frame.
Choice B: 50 mL/hr would result in underdosing the medication as only half of the solution would be infused in 1 hour.
Choice C: 200 mL/hr would result in overdosing the medication as double the required volume would be infused in 1 hour.
Choice D: 150 mL/hr would also result in overdosing the medication as more than the required volume would be infused in 1 hour.
Therefore, the correct answer is A as it ensures the accurate administration of gentamicin over the specified time frame.
