Correct Answer is B
Explanation
Choice A rationale
Placing a baby’s crib next to a heater can pose a risk of overheating or burns. Newborns should be kept at a safe distance from heaters to prevent accidents.
Choice B rationale
Removing extra blankets from the crib is recommended to reduce the risk of suffocation and sudden infant death syndrome (SIDS). This choice reflects an understanding of crib safety.
Choice C rationale
Padding the mattress can pose suffocation risks and is not recommended. A firm mattress without any padding is the safest option for newborns.
Choice D rationale
Placing a baby on their stomach to sleep increases the risk of SIDS. The recommended sleeping position for newborns is on their back, as this significantly reduces the risk.
Correct Answer is ["A","B","C","D"]
Explanation
Step 1 is to convert the child's weight from pounds to kilograms: 28 lb ÷ 2.2 lb/kg = 12.727 kg.
Step 2 is to calculate the dose: 10 mg/kg × 12.727 kg = 127.27 mg.
Step 3 is to determine how many mL is needed: 127.27 mg ÷ (120 mg/5 mL) = 5.3029 mL.
Step 4 is to round to the nearest tenth: 5.3 mL. Final answer: 5.3 mL
