The healthcare provider prescribes oseltamivir for a client who weighs 35 pounds. Recommended dosages for oseltamivir are:
- 30 mg twice a day (BID) for 5 days for a client who weighs less than 33 pounds
- 45 mg BID for 5 days for a client who weighs 34 to 50.6 pounds
- 60 mg BID for 5 days for a client who weighs 51 to 88 pounds
- 75 mg BID for 5 days for a client who weighs more than 88 pounds
Oseltamivir is labeled, "12 mg/mL suspension." How many milliliters should the nurse administer per dose? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["3.8"]
To calculate the volume of oseltamivir suspension, we need to use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Since the client weighs 35 pounds, which is between 34 and 50.6 pounds, the recommended dose is 45 mg BID for 5 days. Plugging in this value and the concentration of oseltamivir suspension, we get:
Volume (mL) = 45 mg / 12 mg/mL
Simplifying, we get:
Volume (mL) = 3.75 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 3.8 mL

Correct Answer is ["4.5"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Volume (mL) / Concentration (mcg)
First, we need to calculate the concentration of nitroglycerin in the solution by dividing the total amount by the total volume. In this case, it is 100 mg / 250 mL.
Since 1 mg is equal to 1,000 mcg, we need to multiply the concentration by 1,000 to get the same units as the dose. In this case, it is 100,000 mcg / 250 mL.
Plugging in the given values, we get:
Infusion rate (mL/h) = 30 mcg/min x 250 mL / 100,000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 0.075 mL/min
To convert minutes to hours, we need to multiply by 60. In this case, it is 0.075 mL/min x 60 min.
Simplifying, we get:
Infusion rate (mL/h) = 4.5 mL/h
Rounding to the nearest tenth, we get:
Infusion rate (mL/h) = 4.5 mL/h
Correct Answer is ["16"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 176 pounds is equivalent to 79.904 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 79.904 kg x 500 mL / 500000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 15.981 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 16 mL/h
