Answer and Explanation

The Correct Answer is ["3"]

Step by step calculation:

The child's weight is 27 lb.

The medication dosage is 10 mg/kg.

The available medication concentration is 200 mg/5 mL.

Calculating the total dose in mg:

Convert the child's weight to kg: 27 lb ÷ 2.2 lb/kg = 12.27 kg

Calculate the total dose: 12.27 kg × 10 mg/kg = 122.7 mg

Calculating the volume to administer:

Use the concentration of the medication: 122.7 mg ÷ (200 mg/5 mL) = 122.7 mg ÷ 40 mg/mL = 3.0675 mL

Rounding the answer:

3.0675 rounds to 3 mL

Correct Answer is ["1"]

Explanation

Step 1: Identify the conversion factor.

We need to convert milliliters (mL) to ounces (oz). The conversion factor is:

1 ounce (oz) = 30 milliliters (mL)

Step 2: Set up the conversion.

The prescribed dose is 30 mL. We want to convert 30 mL to ounces.

Using the conversion factor:

Amount in oz=Amount in mL/Conversion factor=30 mL/30 mL/oz

Step 3: Perform the calculation.

Amount in oz=30/30=1 oz

Step 4: Round the answer (if needed).

1 oz is a whole number

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
