Correct Answer is ["1.5"]
Explanation
Step-by-step calculation:
Convert to milliliters (mL) to teaspoons (tsp).
The conversion factor is: 1 teaspoon (tsp) = 5 milliliters (mL)
Performing the calculation:
Divide the given milliliters by the conversion factor:
7.5 mL ÷ 5 mL/tsp = 1.5 tsp
Rounding the answer: 1.5 is already rounded to the nearest tenth.
Correct Answer is ["0.5"]
Explanation
Convert the child's weight from pounds to kilograms:
55 lb÷2.2=25 kg.
Calculate the total daily dose in mg:
0.3 mg/kg/day×25 kg=7.5 mg/day.
Determine the dose per administration:
The medication is to be given every 8 hours, which equals 3 doses per day.
7.5 mg/day÷3=2.5 mg/dose.
Calculate the number of tablets per dose:
Each tablet contains 5 mg.
2.5 mg÷5 mg/tablet=0.5 tablets.
Round to the nearest tenth:
0.5 tablets
