Correct Answer: B

Rationale: The priority nursing intervention for a 5-year-old child admitted to the hospital with bacterial meningitis is to isolate the child. Isolating the child is crucial to prevent the spread of infection to others, as bacterial meningitis is highly contagious. Administering antibiotics (Choice A) is important in the treatment of bacterial meningitis, but isolating the child takes precedence to protect others. Monitoring vital signs (Choice C) and administering fluids (Choice D) are essential aspects of care for a child with meningitis but are not the priority intervention to prevent the spread of the infection.

Correct Answer: A

Rationale: Abdominal swelling is frequently the initial assessment finding associated with a Wilms tumor. This swelling is caused by the tumor's mass in the kidney, leading to abdominal distension. Weight gain (Choice B) is less likely as a primary finding, as it may occur later due to tumor growth or fluid retention. Hypotension (Choice C) is not typically associated with Wilms tumor unless severe complications like hemorrhage develop. Increased urinary output (Choice D) is not a common initial finding; instead, hematuria or other urinary changes may be observed later in the disease process.

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: The priority nursing diagnosis for a 3-day-old girl with Down syndrome, whose mother had no prenatal care, is imbalanced nutrition, less than body requirements related to the effects of hypotonia. Newborns with Down syndrome often experience feeding difficulties due to hypotonia, which can lead to inadequate nutrition intake. Option B is incorrect because at this age, the infant is not capable of having knowledge deficits related to a genetic disorder. Option C is incorrect as delayed growth and development are not the immediate priority in this scenario. Option D is incorrect as impaired physical mobility is not typically a priority concern for a newborn with Down syndrome.

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.
