A nurse is preparing to administer acetaminophen 10 mg/kg PO every 4 to 6 hours PRN pain to a toddler who weighs 26.4 lb. Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["3.8"]

To calculate the correct dose of acetaminophen for the toddler, follow these steps:

Convert pounds to kilograms:
- 26.4 lb * (1 kg / 2.2 lb) = 12 kg
Calculate the dose in mg:
- 12 kg * 10 mg/kg = 120 mg
Determine the volume to administer:
- 120 mg / 160 mg/5 mL = 3.75 mL

Therefore, the nurse should administer 3.8 mL of acetaminophen per dose.

answer = 3.8

Correct Answer is ["1.2"]

Explanation

Step 1 is to convert the child’s weight from pounds to kilograms since the dosage of morphine is prescribed in mg/kg. We know that 1 kg is approximately equal to 2.2 lb. So, the child’s weight in kg is:

51 lb ÷ 2.2 = 23.18 kg

Step 2 is to calculate the total amount of morphine the child should receive per dose. The doctor ordered 0.1 mg of morphine per kg of body weight. So, the total amount of morphine per dose is:

0.1 mg/kg × 23.18 kg = 2.318 mg

Step 3 is to calculate the volume of morphine injection to be administered. We know that the available morphine injection has a concentration of 2 mg/mL. So, the volume in mL is:

2.318 mg ÷ (2 mg/mL) = 1.159 mL

Rounding this to the nearest tenth gives 1.2 mL. So, the nurse should administer 1.2 mL of morphine injection per dose.

So, the correct answer is 1.2 mL.

Correct Answer is ["0.65"]

Explanation

Let’s calculate this step by step:

Step 1: Convert the toddler’s weight from pounds (lb) to kilograms (kg) using the conversion factor 1 kg = 2.2 lbs.

24 lbs ÷ 2.2 lbs/kg = 10.91 kg

Step 2: Calculate the total amount of diazepam needed using the dosage of 0.3 mg/kg.

0.3 mg/kg × 10.91 kg = 3.27 mg

Step 3: Calculate the volume of diazepam injection to administer using the concentration of 5 mg/mL.

3.27 mg ÷ 5 mg/mL = 0.654 mL

Rounding to the nearest hundredth, the nurse should administer 0.65 mL of diazepam injection.
