A client who weighs 22 pounds receives a prescription for amoxicillin 50 mg/kg/day PO in divided doses every 8 hours. The bottle is labeled "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose?

(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["3.3"]

Calculation Steps:

Step 1: Convert weight from pounds to kilograms: 22 pounds ÷ 2.2 = 10 kg. Result = 10 kg.

Step 2: Calculate the total daily dose of amoxicillin: 50 mg/kg/day × 10 kg = 500 mg/day. Result = 500 mg/day.

Step 3: Calculate the dose per administration: 500 mg/day ÷ 3 doses/day = 166.7 mg/dose. Result = 166.7 mg/dose.

Step 4: Determine how many mL are needed for each dose: 250 mg/5 mL = 50 mg/mL, 166.7 mg ÷ 50 mg/mL = 3.3 mL. Result = 3.3 mL.

Correct Answer is C

Explanation

Choice A reason: Washing for a total of 20 seconds is correct and meets hand hygiene guidelines.

Choice B reason: Lathering using a circular movement is an appropriate technique for thorough handwashing.

Choice C reason: Turning the water off using bare hands can lead to recontamination of the hands. The UAP should use a paper towel to turn off the faucet.

Choice D reason: Holding hands below elbows when rinsing is correct to allow water to run off the hands and prevent contamination.

A. Have the adolescent list the procedural steps for safe insulin administration. B. Review his glycosylated hemoglobin level 3 months after the teaching session. C. Observe him as he demonstrates the self-injection technique to another diabetic adolescent. D. Ask the adolescent to describe his level of comfort with injecting himself with insulin.

Correct Answer is C

Explanation

Choice A reason: Listing the procedural steps is helpful but does not demonstrate practical competence.

Choice B reason: Reviewing glycosylated hemoglobin levels provides information about long-term glucose control but does not directly assess the technique.

Choice C reason: Observing the adolescent as he demonstrates the self-injection technique ensures that he has understood and can correctly perform the procedure, providing the best evaluation of teaching effectiveness.

Choice D reason: Describing the level of comfort provides insight into his confidence but not necessarily his technical competence.
