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 infusion rate, we need to use the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
First, we need to convert the volume from liters to milliliters by multiplying by 1,000. In this case, 1 liter is equivalent to 1,000 mL.
To convert the time from hours to minutes, we need to multiply by 60. In this case, 12 hours is equivalent to 720 minutes.
Plugging in the given values, we get:
Infusion rate (gtt/min) = 1,000 mL x 60 gtt/mL / 720 min
Simplifying, we get:
Infusion rate (gtt/min) = 83.33 gtt/min
Rounding to the nearest whole number, we get:
Infusion rate (gtt/min) = 83 gtt/min
Correct Answer is ["1.3"]
Explanation
To calculate the volume of filgrastim solution, we need to use the formula:
Volume (mL) = Dose (mcg) / Concentration (mcg/mL)
First, we need to calculate the dose by multiplying the prescribed rate by the weight in kilograms. To convert the weight from pounds to kilograms, we multiply by 0.454. In this case, 176 pounds is equivalent to 79.904 kg.
Plugging in the given values, we get:
Volume (mL) = 5 mcg/kg x 79.904 kg / 300 mcg/mL
Simplifying, we get:
Volume (mL) = 1.331 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 1.3 mL
