A nurse is preparing to administer metronidazole 500 mg by intermittent bolus over 60 min. Available is metronidazole 500 mg in 100 ml 0.9% sodium chloride. 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.)
The Correct Answer is ["100"]
To calculate the IV pump rate in mL/hr, you need to divide the volume of the solution in mL by the infusion time in hr. In this case, the formula is 100 mL / 1 hr = 100 mL/hr.
Therefore, the nurse should set the IV pump to deliver 100 mL/hr of metronidazole.

Correct Answer is ["286"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.
Correct Answer is ["30"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr = (30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.
