Correct Answer: C

Rationale: The correct priority intervention for a child with acute laryngotracheobronchitis is to place a tracheotomy set at the bedside. Acute laryngotracheobronchitis can lead to airway obstruction, making it essential to have the equipment readily available in case of emergency. Padding the side rails, arranging for a quiet room, or obtaining a recliner for a parent are not the immediate priorities in managing a child with this condition.

Correct Answer: B

Rationale: Colicky behavior in infants is primarily characterized by paroxysmal abdominal pain, resulting in excessive crying and fussiness. The pain episodes are often unpredictable and can be distressing for both the infant and the parents. Inadequate peristalsis (Choice A) refers to weak or ineffective bowel movements and is not the typical cause of colic. While some infants may experience colic due to an allergic response to certain proteins in milk (Choice C), this is not the primary cause of colic behavior in all infants. Choice D, a protective mechanism designed to eliminate foreign proteins, is not a recognized cause of colic. Therefore, the correct explanation for the cause of colicky behavior in infants is paroxysmal abdominal pain.

Correct Answer: C

Rationale: The correct answer is C. The child's behavior of smiling easily, interacting happily with nurses, and showing disinterest in the parent when they visit indicates that the child has emotionally withdrawn and accepted the separation. This response suggests that the child may have given up fighting against the separation from the parent due to prolonged hospitalization. Choices A, B, and D are incorrect. Choice A about the child repressing feelings towards the parent is not supported by the scenario. Choice B about routines and feeling safe does not address the emotional aspect of the child's behavior. Choice D about improved behavior due to feeling better physically does not explain the emotional dynamics at play in the child's behavior.

Correct Answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.

Correct Answer: D

Rationale: Elevating the head of the bed is essential in the care of an infant with RSV as it helps improve breathing by reducing congestion and promoting drainage. This position also aids in maintaining patent airways and can enhance comfort for the infant. Providing small, frequent feedings (Choice A) is generally appropriate for infants but is not a specific intervention for RSV. Administering antibiotics (Choice B) is not indicated for RSV, as it is a viral infection and antibiotics are ineffective against viruses. Maintaining strict isolation (Choice C) is important to prevent the spread of infections, but it is not a direct care intervention for managing RSV symptoms.
