Correct Answer: C

Rationale: The most appropriate response for the nurse is to emphasize the importance of consistency in discipline when dealing with toddlers. Toddlers are at an age where they are learning boundaries and acceptable behaviors. By being consistent, parents can help their child understand what is expected of them and establish a sense of structure and routine. Choices A, B, and D do not provide constructive advice or guidance on how to address the issue of disciplining a 2-year-old. Choice A merely acknowledges the age without providing guidance, choice B seeks more information without offering support, and choice D labels the age without offering practical advice on discipline.

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: A full-thickness (third-degree) burn involves the destruction of all layers of skin, including the epidermis, dermis, and extending into the subcutaneous tissue. This type of burn results in significant tissue damage and can appear pale, charred, or leathery. Choice A is incorrect as erythema and pain are more characteristic of superficial burns. Choice B describes a partial-thickness burn where the skin shows erythema followed by blister formation, involving the epidermis and part of the dermis. Choice D is incorrect as it describes a deeper type of injury involving structures beyond the skin layers, such as muscle, fascia, and bone, which is not specific to a full-thickness burn.

Correct Answer: C

Rationale: The correct answer is to place a tracheotomy set at the bedside. Acute laryngotracheobronchitis can cause airway obstruction, which may require an emergency tracheotomy. Having the tracheotomy set readily available ensures quick access in case of respiratory distress. Padding the side rails of the crib, arranging for a quiet, cool room, and obtaining a recliner for a parent are important aspects of care but are not the priority when managing a potentially life-threatening airway emergency.

Correct Answer: D

Rationale: The Resiliency model of family stress, adjustment, and adaptation is the appropriate theory in this scenario. This model focuses on identifying risks and protective factors that help families achieve positive outcomes despite challenges. Duvall's developmental theory primarily focuses on family life cycle stages, Friedman's structural functional theory emphasizes the interdependence of family members, and Von Bertalanffy's general system theory applied to families looks at the family as a dynamic system. These theories do not specifically address the concept of resilience and adaptation in the face of stressors like homelessness.
