Correct Answer is D

Explanation

Choice A rationale

Examining the tympanic membrane at the beginning may cause distress to the child and make the rest of the exam difficult.

Choice B rationale

Before auscultating the chest and abdomen, the child needs to be calm and cooperative, which might not be the case if their ear is examined first.

Choice C rationale

Examining the tympanic membrane before the head and neck could lead to increased anxiety and uncooperativeness in the child during the rest of the exam.

Choice D rationale

Examining the tympanic membrane at the end allows for a more accurate and complete examination without causing the child to become distressed early in the process.

Correct Answer is ["A","B","C","D"]

Explanation

Step 1 is to convert the child's weight from pounds to kilograms: 28 lb ÷ 2.2 lb/kg = 12.727 kg.

Step 2 is to calculate the dose: 10 mg/kg × 12.727 kg = 127.27 mg.

Step 3 is to determine how many mL is needed: 127.27 mg ÷ (120 mg/5 mL) = 5.3029 mL.

Step 4 is to round to the nearest tenth: 5.3 mL. Final answer: 5.3 mL
