Correct Answer: A

Rationale: Von Bertalanffy's general system theory applied to families emphasizes the family as a system with interdependent, interacting parts that endure over time to ensure the survival, continuity, and growth of its components. This perspective views the family as a dynamic entity where each member's actions and behaviors impact the overall functioning of the family unit. Choice B is incorrect because it focuses more on the social aspects of family structure rather than the systemic view provided by Von Bertalanffy's theory. Choice C is incorrect as it pertains more to the family life cycle theory, which is different from the general system theory. Choice D is incorrect as it addresses stress response within families, a concept not central to Von Bertalanffy's general system theory.

Correct Answer: D

Rationale: Explaining the use of prescribed medications is crucial as it helps ensure the proper management of the child's condition post-discharge. Understanding how and when to administer medications is essential for the child's recovery. While teaching the parents about signs of infection, providing wound care instructions, and scheduling follow-up appointments are also important aspects of care, ensuring the correct use of prescribed medications takes precedence to prevent complications and promote the child's well-being.

Correct Answer: A

Rationale: Encouraging regular physical activity is crucial in managing symptoms and improving joint function in juvenile idiopathic arthritis. It helps maintain joint mobility, muscle strength, and overall well-being. Providing a high-calorie diet (Choice B) is not typically recommended unless there are specific nutritional concerns or growth issues. A low-sodium diet (Choice C) may be beneficial in conditions like hypertension, but it is not a primary focus for JIA management. Administering intravenous fluids (Choice D) is not a routine part of managing JIA unless specifically indicated for hydration or medication administration.

Correct Answer: D

Rationale: In a 3-year-old child presenting with sudden respiratory distress without fever or recent illness, the most likely cause is a foreign body airway obstruction. Foreign body airway obstruction can lead to a sudden onset of respiratory distress as it blocks the air passage. Croup typically presents with a barking cough and stridor, often preceded by a viral illness. Epiglottitis is characterized by high fever, drooling, and a muffled voice. Lower respiratory infections usually present with symptoms such as cough, fever, and chest congestion. Therefore, in this case, the absence of recent illness or fever makes foreign body airway obstruction the most likely cause of the respiratory distress.

Correct Answer: B

Rationale: Upright positioning is the optimal intervention to promote maximum chest expansion in a child with Duchenne muscular dystrophy. By placing the child in an upright position, gravity can assist in expanding the chest cavity, facilitating better lung expansion and improving breathing efficiency. Deep-breathing exercises may be beneficial but are not as effective in maximizing chest expansion as upright positioning. Coughing and chest percussion focus more on airway clearance and are not directly aimed at promoting chest expansion.
