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
Threatening a shot can cause fear and anxiety, potentially making the child more resistant to taking medication in the future.
Choice B rationale
Hiding medication in food can lead to mistrust if the child discovers it, and it's not a sustainable long-term solution.
Choice C rationale
Telling the child the medicine tastes like candy is misleading and can lead to distrust. It's important to be honest while finding practical solutions.
Choice D rationale
Offering an ice pop prior can numb the taste buds, making the medication more palatable without deceit, and can build positive associations with taking medication.
Correct Answer is C
Explanation
Choice A rationale
The infant's birth weight typically doubles by 4-6 months and triples by 1 year of age. If an infant's weight has tripled at 6 months, it may indicate overnutrition or an underlying health condition.
Choice B rationale
Lateral incisors usually appear between 9 to 13 months. At 6 months, the central incisors are more likely to be emerging.
Choice C rationale
The posterior fontanel typically closes by 2 to 3 months of age. Therefore, by 6 months, it is expected to be closed.
Choice D rationale
Infants usually sit without support around 8 months. At 6 months, they may sit with support or briefly without support but not consistently.
