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

Explanation
To calculate the amount of heparin received, we need to use the formula:
Amount (units) = Infusion rate (mL/h) x Time (h) x Concentration (units/mL)
First, we need to calculate the concentration of heparin in the solution by dividing the total units by the total volume. In this case, it is 20,000 units / 500 mL.
Plugging in the given values, we get:
Amount (units) = 15 mL/h x 12 h x 20,000 units / 500 mL
Simplifying, we get:
Amount (units) = 7,200 units
Correct Answer is ["17"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 0.5 mg/min x 200 mL / 360 mg
Simplifying, we get:
Infusion rate (mL/h) = 100 mL / 360 min
Converting minutes to hours, we get:
Infusion rate (mL/h) = 100 mL / 6 h
Dividing both sides by 6, we get:
Infusion rate (mL/h) = 16.67 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 17 mL/h
