A nurse is preparing to administer vancomycin 1 g in 250 ml 0.9% sodium chloride by intermittent IV bolus over 90 min. 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 ["167"]
To calculate the infusion rate for the IV pump, we need to divide the total volume of the solution (250 mL) by the infusion time (90 min). This gives us:
250 mL / 90 min = 2.778 mL/min
To convert this to mL/hr, we need to multiply by 60 min/hr. This gives us: 2.778 mL/min x 60 min/hr = 166.667 mL/hr
To round this to the nearest whole number, we look at the tenths place and see that it is 6, which is equal to or greater than 5, so we round up and drop the rest of the digits. This gives us:
167 mL/hr
Therefore, the nurse should set the IV pump to deliver 167 mL/hr.

Correct Answer is ["1"]
Explanation
To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (50 mcg / 0.05 mg) x 1 mL = 1 mL. Round to the nearest whole number: 1 mL.
Correct Answer is ["38"]
Explanation
To solve this problem, the nurse needs to find the concentration of lidocaine in the solution, which is 1 g / 250 mL = 0.004 g/mL.
Then, the nurse needs to convert the dosage of lidocaine from mg/min to g/hr, which is 2.5 mg/min x 60 min/hr x 0.001 g/mg = 0.15 g/hr. Finally, the nurse needs to divide the dosage by the concentration to get the infusion rate, which is 0.15 g/hr / 0.004 g/mL = 37.5 mL/hr.
Rounding to the nearest whole number, the nurse should set the IV pump to deliver 38 mL/hr.
