Correct Answer: A

Rationale: The correct answer is A: Risk for impaired skin integrity due to the cast and its location. When a child has a long-leg hip spica cast, the priority nursing diagnosis is to prevent impaired skin integrity. This is because the child's mobility is restricted, and pressure from the cast can lead to skin breakdown. Option B is incorrect as while education is essential, it is not the priority when skin integrity is at risk. Option C is incorrect because while immobility can impact development, immediate skin integrity concerns take precedence. Option D is incorrect as self-care deficit, while important, is secondary to preventing skin breakdown in this scenario.

Correct Answer: C

Rationale: Administering antibiotics is crucial post-tonsillectomy to prevent infection, as the surgical site is susceptible to bacterial growth. Encouraging deep breathing exercises can also be beneficial for lung expansion and preventing respiratory complications. However, administering antibiotics takes precedence as it directly addresses the risk of infection. Encouraging the child to eat may not be appropriate immediately post-tonsillectomy due to the risk of throat irritation and potential discomfort. Applying ice to the throat is typically not recommended after a tonsillectomy, as it may constrict blood vessels and hinder the healing process.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial in managing symptoms and ensuring proper nutrition in children with ADHD. Dietary factors can influence ADHD symptoms. While sleep patterns, academic performance, and behavior at home are important aspects to consider, dietary assessment plays a significant role in the management of ADHD.

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: Rapid acting insulin will help lower the elevated blood glucose level quickly.
