D.

12.5 mL/hr

Answer and Explanation

The Correct Answer is A

Given:

Volume of fluid: 3,000 mL

Infusion time: 24 hours

Formula:

Flow rate (mL/hr) = Volume (mL) / Time (hr)

Step 1: Calculate the infusion rate in mL/hr:

Flow rate (mL/hr) = 3,000 mL / 24 hr

Flow rate (mL/hr) = 125 mL/hr

Correct Answer is C

Explanation

Given:

Ordered dose of acetaminophen: 10 mg/kg

Child's weight: 22 lb

Concentration of acetaminophen liquid: 160 mg/5 mL

Step 1: Convert child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 22 lbs x 0.453592 kg/lb = 9.976824 kg

Step 2: Calculate the total dose of acetaminophen:

Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)

Total dose (mg) = 10 mg/kg x 9.976824 kg

Total dose (mg) = 99.76824 mg

Step 3: Calculate the volume to be administered:

Volume (mL) = Total dose (mg) / Concentration (mg/mL)

Volume (mL) = 99.76824 mg / 160 mg/5 mL

Volume (mL) = 99.76824 mg x (5 mL / 160 mg)

Volume (mL) = 3.1177575 mL

Step 4: Round to the nearest tenth:

Volume (mL) ≈ 3.1 mL

Correct Answer is B

Explanation

Given:

Ordered volume of Isomil: 12 oz

Step 1: Determine the volume of Isomil needed for 1/4 strength:

Volume of Isomil for 1/4 strength = Original volume x (1/4)

Volume of Isomil for 1/4 strength = 12 oz x (1/4)

Volume of Isomil for 1/4 strength = 3 oz

Step 2: Calculate the volume of solvent (water) needed:

Solvent volume = Original volume - Volume of Isomil for 1/4 strength

Solvent volume = 12 oz - 3 oz

Solvent volume = 9 oz

Step 3: Convert ounces to milliliters:

1 oz = 29.5735 mL

Solvent volume (mL) = 9 oz x 29.5735 mL/oz

Solvent volume (mL) = 266.1615 mL

Step 4: Round to the nearest whole number:

Solvent volume (mL) ≈ 270 mL
