A child who weighs 18 pounds receives a prescription for amoxicillin 25 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labelled, "Amoxicillin for Oral Suspension, USP 400 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 ["1.3"]

1.3 mL of amoxicillin suspension with each dose.

To calculate the correct dose of amoxicillin to give to the child, follow these steps:

Step 1: Convert the child's weight from pounds to kilograms. 18 pounds ÷ 2.2 = 8.18 kilograms

Step 2: Calculate the total daily dose of amoxicillin. 25 mg/kg/day x 8.18 kg = 204.5 mg/day

Step 3: Divide the total daily dose into two equal doses to be given every 12 hours. 204.5 mg/day ÷ 2 doses = 102.25 mg/dose

Step 4: Determine how many mL of the suspension contain 102.25 mg of amoxicillin. 400 mg/5 mL = 80 mg/mL 102.25 mg ÷ 80 mg/mL = 1.28 mL

Correct Answer is A

Explanation

The nurse should prepare the mother for a sweat-chloride test to screen for cystic fibrosis (CF). A sweat- chloride test measures the amount of chloride in the sweat and is used to diagnose CF. CF is a genetic disorder that can cause the body to produce thick, sticky mucus that can clog the lungs and pancreas. One of the symptoms of CF is salty-tasting skin due to an increased amount of salt in the sweat. The other options (B, C, and D) are not standard diagnostic tests for screening for CF.

A. Inspect the posterior oropharynx. B. Touch the tonsillar pillars to stimulate the gag reﬂex. C. Ask the child to speak to evaluate change in voice tone. D. Assess for teeth clenching or grinding.

Correct Answer is A

Explanation

The nurse should inspect the posterior oropharynx of a child who is frequently swallowing after tonsillectomy to assess for bleeding or the presence of clots. Swallowing frequently can be a sign of postoperative bleeding, which is a potential complication of tonsillectomy.

Touching the tonsillar pillars to stimulate the gag reﬂex or asking the child to speak would not provide information about the presence of bleeding.

Assessing for teeth clenching or grinding is not related to this particular observation.
