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 ["0.25"]
Explanation
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.
Correct Answer is ["60"]
Explanation
To calculate the infusion rate of lidocaine, we need to convert the dose from mg/min to mg/hr and then to mL/hr.
The prescribed dose is 4 mg/min, so the hourly dose is 4 x 60 = 240 mg/hr.
The concentration of the drug is 1 g in 250 mL, which is equivalent to 1000 mg in 250 mL or 4 mg in 1 mL.
Therefore, the volume per hour is 240 / 4 = 60 mL/hr.
Rounded to the nearest whole number, the nurse should set the IV pump to deliver 60 mL/hr.
