A primary healthcare provider prescribes a medication of 1250 mg diluted in 1000 mL. A nurse starts the infusion at 09:20 at a rate of 250 mL/hr. What time will the intravenous (IV) infusion be completed?
11:20
12:20
13:20
14:20
The Correct Answer is C
To calculate the total infusion time, we need to divide the total volume to be infused by the infusion rate:.
Total infusion time = Total volume to be infused / Infusion rate.
In this case, the total volume to be infused is 1000 mL, and the infusion rate is 250 mL/hr:.
Total infusion time = 1000 mL / 250 mL/hr. Total infusion time = 4 hours.
Therefore, the infusion will be completed 4 hours after it was started at 09:20, which would be at 13:20.

Correct Answer is A
Explanation
First, we need to convert the weight of the child from pounds to kilograms:. 44 lb / 2.2046 = 19.958 kg (rounded to three decimal places).
Next, we can calculate the dose of glycopyrrolate:. 0.02 mg/kg x 19.958 kg = 0.39916 mg.
We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 0.39916 mg seems reasonable for a child with chronic severe drooling..
Now, we need to determine how much medication to administer to the child. We know that 5 mL of medication contains 1 mg of drug. Therefore, to administer 0.39916 mg of glycopyrrolate, we need to administer:
(0.39916 mg / 1 mg) x 5 mL = 1.9958 mL.
We should round this dose to the nearest appropriate unit of measure. In this case, we can round to 2 mL to make it easier to measure and administer..
Therefore, the nurse should administer 2 mL of glycopyrrolate to the child three times a day (tid) to treat chronic severe drooling.
Correct Answer is C
Explanation
The correct answer is choice C, 3 tablets. To calculate the number of tablets, divide the ordered dose by the available dose:
75 mg ÷ 25 mg = 3
The nurse should administer 3 tablets of Coumadin 25 mg to the patient to give a total dose of 75 mg.
