The health care provider prescribes streptomycin 300 mg IM q12 hours for a client with tuberculosis. The available vial is labeled "Streptomycin 1 gram/2.5 mL." How many milliliters should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.8"]
To calculate the number of milliliters the nurse should administer, we can use the following formula:
Dose to administer = Ordered dose / Available dose
In this case, the ordered dose is 300 mg and the available dose is 1 g/2.5 mL. We can calculate the dose to administer as follows:
300 mg / 1000 mg/2.5 mL = 0.75 mL.
Rounded off: 0.8mL

Correct Answer is ["20"]
Explanation
An infant is receiving 10 mL of 20% intralipids infusing at 0.5 mL/hour.
To calculate the infusion time in hours, we need to divide the total volume of the infusion (10 mL) by the infusion rate (0.5 mL/hour).
The IV will infuse for 20 hours (10 mL / 0.5 mL/hour).
Correct Answer is ["1930"]
Explanation
The healthcare provider prescribes an IV solution of ampicillin 1 gram in 50 mL of Dextrose in Water (D/W) at 25 drops/minute.
The nurse uses an infusion set that delivers 15 drops/mL.
This means that the infusion rate is 1.67 mL/minute (25 drops/minute ÷ 15 drops/mL = 1.67 mL/minute).
Since the total volume of the solution is 50 mL, it will take approximately 30 minutes to infuse the entire solution (50 mL
÷ 1.67 mL/minute = 30 minutes).
If the nurse starts the infusion at 1900 (7:00 PM), the infusion should be completed at approximately 1930 (7:30 PM).
