A two-year-old toddler who weighs 30 pounds is diagnosed with otitis media. The physician ordered the antibiotic amoxicillin 20mg/kg PO q8 h. The label reads 125 mg in 5 ml. How many millimeters will you administer?

1.75ml

10.9ml

20ml

5ml

Answer and Explanation

The Correct Answer is B

Convert weight to kilograms:
30 lb ÷ 2.2 = 13.64 kg

Calculate dose in mg:
20 mg/kg × 13.64 kg = 272.8 mg per dose

Determine volume to administer:
If 125 mg = 5 mL, then:
(272.8 mg × 5 mL) ÷ 125 mg = 10.912 mL

Round to the nearest tenth:
10.912 mL ≈ 10.9 mL

Correct Answer is C

Explanation

A. Children with Down syndrome typically exhibit short stature, not excessive height.
B. While children with Down syndrome may have a single transverse palmar crease, not "spots on the palms," this is not the most defining physical feature.
C. One of the hallmark physical characteristics of Down syndrome is hypotonia (low muscle tone). It often leads to delayed motor development, poor head control, and floppy posture in infancy.
D. Children with Down syndrome are more likely to have hyperflexible joints due to ligamentous laxity, not inflexibility.

A. weight gain B. hyperactivity C. pink mucous membranes D. poor nutritional intake

Correct Answer is D

Explanation

A. Weight gain is typically a sign of adequate nutrition and growth, not a concern for a cardiac defect.
B. Hyperactivity is not characteristic of infants, especially at 1 month of age, and is not a common sign of a cardiac issue in this age group.
C. Pink mucous membranes indicate adequate oxygenation, which does not suggest a cardiac defect.
D. Poor nutritional intake in an infant may signal an underlying cardiac defect, particularly if accompanied by fatigue with feeding, diaphoresis, or failure to thrive. Infants with congenital heart defects often have difficulty feeding due to increased energy expenditure and reduced oxygenation, making this a key red flag.
