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: B

Rationale: Lifting the baby by supporting the head and neck can cause fractures in infants with osteogenesis imperfecta. Caregivers should avoid lifting infants in this manner due to the risk of injury. Choices A, C, and D demonstrate correct understanding of how to prevent injuries in infants with osteogenesis imperfecta by avoiding excessive force on the arms or legs, preventing awkward positions, and lifting the legs in a safer manner to change diapers.

Correct Answer: B

Rationale: The correct answer is B: Obesity. Children with Down syndrome are at a higher risk of obesity due to various factors such as lower metabolic rate, hormonal imbalances, and reduced physical activity levels. Addressing healthy eating habits early can help prevent obesity in these children. Choice A (Rickets) is incorrect because rickets is primarily associated with vitamin D deficiency and is not a common nutritional problem in children with Down syndrome. Choice C (Anemia) is incorrect as anemia may not be a common nutritional problem specific to children with Down syndrome. Choice D (Rumination) is incorrect as rumination is a behavioral disorder characterized by repeated regurgitation of food and is not a common nutritional problem associated with Down syndrome.

Correct Answer: A

Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms, which are a serious complication of this condition. Coronary artery aneurysms can lead to long-term cardiovascular issues, making prevention crucial. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is on preventing coronary artery aneurysms. Dehydration prevention is also essential but not the primary goal during the acute phase of this disease.

Correct Answer: C

Rationale: In a child diagnosed with acute glomerulonephritis, monitoring urine output is a crucial assessment. Acute glomerulonephritis affects the kidneys, leading to decreased urine output due to impaired kidney function. Monitoring urine output helps assess renal perfusion, fluid status, and kidney function. This assessment is essential in determining the effectiveness of treatment and identifying complications. Monitoring blood glucose levels (Choice A) is not directly related to acute glomerulonephritis. Respiratory rate (Choice B) may be important in other conditions but is not a key assessment for acute glomerulonephritis. Monitoring for signs of infection (Choice D) is important in general, but it is not specific to the primary issue of impaired kidney function in acute glomerulonephritis.
