Correct Answer is A
Explanation
Choice A rationale
Washing a baby’s face with plain water is a safe and effective way to keep it clean without causing irritation or dryness. This is especially important for newborns, whose skin is more sensitive than that of older children and adults.
Choice B rationale
Bumper pads are not recommended for use in a baby’s crib. They pose a risk of suffocation, strangulation, and entrapment. Instead, the crib should be kept bare, with only a firm mattress and a fitted sheet.
Choice C rationale
A soft mattress is not safe for a baby’s crib. It increases the risk of sudden infant death syndrome (SIDS) because it can conform to the shape of the baby’s head or face, leading to suffocation. A firm mattress is recommended.
Choice D rationale
Bathing a baby immediately after feeding is not recommended. It can cause discomfort and may lead to vomiting. It’s better to wait at least a little while after a feeding before bathing the baby.
