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 C
Explanation
We need to calculate the patient's BSA using one of the available formulas. The most widely used formula is the Du Bois formula, which is:.
BSA = 0.007184 × W^0.425 × H^0.725.
where W is weight in kg and H is height in cm.. Plugging in the patient's weight and height, we get:. BSA = 0.007184 × 94.5^0.425 × 185^0.725
BSA = 2.15 m².
Now, we can use the physician's order to find the daily dose and the total dose of Platinol for this patient. The daily dose is:.
Daily dose = 20 mg/m²/day × BSA Daily dose = 20 mg/m²/day × 2.15 m² Daily dose = 43 mg/day.
The total dose for 5 days is:.
Total dose = Daily dose × Number of days Total dose = 43 mg/day × 5 days
Total dose = 215 mg.
Therefore, the patient's dose of Platinol would be 215 mg in total, or 43 mg per day for 5 days.
Correct Answer is A
Explanation
Robitussin DM contains 100 mg of guaifenesin per 1 teaspoon. One teaspoon is equivalent to 5 milliliters, so 100 mg is present in 5 mL. Therefore, 10 mL of Robitussin DM contains 2 times the amount of guaifenesin in 1 teaspoon or 200 mg.
