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.)
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
