Hesi Medical Dosage Calculation
Hesi Medical Dosage Calculation ( 53 Questions)
A child who weighs 66 pounds receives a prescription for amoxicillin 80 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 400 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only.)
To find out how many mL of amoxicillin to administer, we need to first convert the child's weight from pounds to kilograms, since the prescription is based on kg. To do this, we multiply 66 pounds by 0.454, which gives us 29.964 kg.
Then, we multiply this by the prescribed dose (80 mg/kg/day) to get the total daily dose of amoxicillin, which is 2397.12 mg.
Next, we divide this by the number of doses per day (2) to get the dose per 12 hours, which is 1198.56 mg.
Finally, we divide this by the concentration of the suspension (400 mg per 5 mL) to get the volume to administer, which is 14.98 mL.
We can round this up to 15 mL as the answer.
