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 theory focuses on viewing the family as a dynamic system where each member's actions and behaviors impact the whole family unit. Choice B is incorrect as it focuses solely on the social system of the family, while Von Bertalanffy's theory looks at the family as a whole system. Choice C is incorrect as it discusses family developmental stages, which is not the main emphasis of Von Bertalanffy's theory. Choice D is also incorrect as it only addresses how families respond to stress, which is a narrower focus compared to the broader system view of Von Bertalanffy's theory.

Correct Answer: A

Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.

Correct Answer: A

Rationale: The correct answer is A: Parallel. Toddlers typically engage in parallel play, where they play alongside but not directly with other children. This type of play is common during early childhood as children are still developing social skills and may prefer to play independently while observing others. Choice B, Solitary play, refers to a child playing alone without interacting with others. Choice C, Cooperative play, involves children playing together towards a common goal or activity. Choice D, Competitive play, emphasizes winning and outperforming others, which is less common in toddlers as they are in the stage of exploring and learning through play rather than competing.

Correct Answer: C

Rationale: In children with type 1 diabetes, it is essential to emphasize the need for extra snacks before exercise to prevent hypoglycemia. Choice A is incorrect because exercise typically lowers blood glucose levels, not increases them. Choice B is inappropriate as exercise is beneficial but needs to be managed carefully. Choice D is inaccurate as extra insulin during exercise can lead to hypoglycemia.

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.
