Calculation
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.)
mL
Explanation & Rationale
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
