A nurse is preparing to administer buprenorphine 4 mcg/kg IV bolus to a child who weighs 74 lb. Available is buprenorphine injection 0.3 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.45"]

Calculating the total dose in mg:

Convert the child's weight to kg: 74 lb ÷ 2.2 lb/kg = 33.64 kg

Calculate the total dose: 33.64 kg × 4 mcg/kg = 134.56 mcg

Converting mcg to mg:

1 mg = 1000 mcg

134.56 mcg ÷ 1000 mcg/mg = 0.13456 mg

Calculating the volume to administer:

Use the concentration of the medication: 0.13456 mg ÷ 0.3 mg/mL = 0.45 mL

Correct Answer is ["2.3"]

Explanation

Step-by-step calculation:

The child's weight is 77 lb.

The medication dosage is 10 mg/kg.

The available medication concentration is 150 mg/mL.

Calculating the total dose in mg:

Convert the child's weight to kg: 77 lb ÷ 2.2 lb/kg = 35 kg

Calculate the total dose: 35 kg × 10 mg/kg = 350 mg

Calculating the volume to administer:

Use the concentration of the medication: 350 mg ÷ 150 mg/mL = 2.33 mL

Rounding the answer:

2.33 rounds to 2.3 mL

Correct Answer is ["2.7"]

Explanation

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

We know that 1 kg = 2.2 lb,

Weight in kg=Weight in lb=78/2.2≈35.45 kg

Step 2: Calculate the required dose of ondansetron in mg.

The prescribed dose is 0.15 mg per kg:

Dose in mg=0.15 mg/kg×35.45 kg=5.318 mg

Step 3: Determine the volume of ondansetron to administer.

To determine how many mL the nurse should administer, we use the following formula:

Volume (mL)=Dose in mg/Concentration in mg/mL=5.318 mg/2 mg/mL=2.659 mL

Step 4: Round the answer:

Rounding 2.659 mL gives 2.7 mL.
