A nurse is preparing to administer a dexamethasone 1.5 mg/kg/day PO to divide equally every 6 hr to a preschool-age child who weighs 22 lb. Available is dexamethasone oral solution 1 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth.
Use a leading zero if it applies. Do not use a trailing zero.)
Step 1: lb ÷ (2.2 lb/kg) = 10 kg
Step 2:.5 mg/kg/day × 10 kg = 15 mg/day
Step 3: mg/day ÷ 4 doses/day = 3.75 mg/dose
Step 4:.75 mg ÷ 1 mg/mL = 3.75 mL per dose
The calculated answer is 3.8 mL (rounded to the nearest tenth).
Correct Answer : A,B,C,D,E
Step 1: lb ÷ (2.2 lb/kg) = 10 kg
Step 2:.5 mg/kg/day × 10 kg = 15 mg/day
Step 3: mg/day ÷ 4 doses/day = 3.75 mg/dose
Step 4:.75 mg ÷ 1 mg/mL = 3.75 mL per dose
The calculated answer is 3.8 mL (rounded to the nearest tenth)

Correct Answer is D
Explanation
Choice A rationale
Introducing well-cooked table foods should begin around 8-10 months of age when the baby is ready for finger foods and has developed better chewing skills.
Choice B rationale
Starting solid foods at 3 months old is too early and can interfere with breastfeeding or formula feeding, increasing the risk of allergies and digestive issues.
Choice C rationale
Cow's milk should not be introduced until 12 months of age, as infants need the nutrients from breast milk or formula during their first year for optimal growth.
Choice D rationale
It is recommended to wait until the baby is at least 6 months old before introducing fruit juice, and even then, it should be given in limited quantities to avoid excessive sugar intake.
Correct Answer is D
Explanation
Choice A rationale
Assisting with crutch walking is necessary but should occur only after ensuring the cast is properly set and stable to avoid injury.
Choice B rationale
Avoiding touch until the cast is dry is unnecessary and impractical. The nurse can handle the cast gently without causing damage.
Choice C rationale
Using a heat lamp can lead to skin burns or uneven drying, which might weaken the cast.
Choice D rationale
Applying moleskin to the edges protects the child’s skin from irritation and breakdown, promoting comfort and skin integrity.
