A child weighing 18 pounds has been prescribed amoxicillin at a dosage of 25 mg/kg/day. The medication is to be administered orally in two divided doses every 12 hours.

The label on the bottle reads, “Amoxicillin for Oral Suspension, USP 400 mg per 5 mL.”. How many mL should the nurse administer for each dose? (Provide a numerical value only.

If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

Step 1: First, convert the child’s weight from pounds to kilograms. Since 1 pound is approximately 0.45 kilograms, an 18-pound child weighs about 8.16 kilograms (18 pounds × 0.45 kg/pound).

Step 2: Next, calculate the total daily dosage of amoxicillin. The prescribed dosage is 25 mg/kg/day. Therefore, the total daily dosage is 204 mg/day (8.16 kg × 25 mg/kg).

Step 3: Since the medication is to be administered in two divided doses every 12 hours, each dose should be half of the total daily dosage. Therefore, each dose is 102 mg (204 mg/day ÷ 2).

Step 4: Finally, calculate the volume of the suspension to be administered for each dose. The label on the bottle reads, “Amoxicillin for Oral Suspension, USP 400 mg per 5 mL.”. Therefore, each milliliter of the suspension contains 80 mg of amoxicillin (400 mg/5 mL). To administer a dose of 102 mg, the nurse should administer approximately 1.275 mL (102 mg ÷ 80 mg/mL). If rounding is required, round to the nearest tenth.

Therefore, the nurse should administer 1.3 mL for each dose.

Correct Answer is C

Explanation

Choice A rationale
Recognizing most letters and numbers is a skill that typically develops later in childhood, not at 3 years old.
Choice B rationale
Using 1-word sentences is a skill that is typically mastered by 2 years old. A 3-year-old child is usually able to speak in longer sentences.
Choice C rationale
Speaking in simple sentences with four or more words is a normal developmental milestone for a 3-year-old child.
Choice D rationale
Using gestures with 1 to 2-word sentences is a skill that is typically mastered by 2 years old. A 3-year-old child is usually able to speak in longer sentences.

A. Frequency of urination B. Any recent changes in diet C. Presence of any unusual odors in the urine D. Any changes in the color of the urine

Correct Answer is A

Explanation

Choice A rationale
In evaluating a preschool-aged child presenting with symptoms of flank pain, dysuria, and a low-grade fever for a possible urinary tract infection (UTI), the nurse should obtain additional information from the parent about the frequency of urination. Increased frequency of urination is a common symptom of UTI in children.
Choice B rationale
While dietary changes can affect the color and odor of urine, they are not typically associated with the symptoms of a UTI.
Choice C rationale
Unusual odors in the urine can be a sign of a UTI. However, this symptom alone is not definitive for a UTI and should be considered in conjunction with other symptoms and findings.
Choice D rationale
Changes in the color of the urine can be a sign of a UTI, as the urine may appear cloudy or have a pink or red color due to the presence of blood. However, this symptom alone is not definitive for a UTI and should be considered in conjunction with other symptoms and findings.
