Correct Answer: D

Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.

Correct Answer: A

Rationale: The correct answer is giving a pacifier to the newborn. Sucking is a natural reflex and a source of comfort for newborns, especially postoperatively. A pacifier can help meet their developmental needs by providing soothing comfort. Choices B, C, and D do not directly address the major developmental need related to the newborn's comfort and reflexes postoperatively. Putting a mobile over the crib, providing a cuddly toy, or warming formula, although potentially beneficial in other contexts, do not specifically target the developmental need of sucking for comfort. Offering a pacifier is a safe and effective way to address this developmental need in newborns.

Correct Answer: B

Rationale: In a situation where a limb is protruding from the vagina during active labor, the correct management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord and improves oxygenation to the fetus. Administering oxygen is important to ensure adequate oxygen supply to both the mother and the baby. Providing transport is necessary for prompt transfer to a medical facility for further management. Applying gentle traction to the protruding limb is not recommended as it can cause harm to the baby and should be avoided. Giving 100% oxygen and attempting to manipulate the protruding limb is not the correct approach and can potentially lead to further complications.

Correct Answer: C

Rationale: The correct answer is C. Moving a child to a regular bed by the age of three can increase the risk of falls as young toddlers may not have the motor skills to safely navigate a larger bed. This indicates a need for more teaching on safety measures. Choices A, B, and D are all appropriate safety measures that can help prevent accidents and injuries in young children. Keeping medications in a medicine cabinet, having secured gates at entrances to staircases, and choosing shoes that fasten with Velcro instead of laces are all good practices to ensure a safe environment for toddlers.

Correct Answer: B

Rationale: Encouraging fluid intake is essential in the discharge instructions for a child who has had a tonsillectomy. It helps keep the throat moist, aids in preventing dehydration, and promotes healing. Gargling with salt water is not typically recommended after a tonsillectomy as it may irritate the surgical site. Providing the child with hard candy is not advisable as it can irritate the throat and potentially cause harm. Applying heat to the neck is also not recommended post-tonsillectomy as it can increase swelling and discomfort in the surgical area.
