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: When observing a toddler in a playroom with other children, a caregiver would expect to witness parallel play. Parallel play is common among toddlers, where they play alongside but not directly with other children. This type of play is characterized by children engaging in similar activities near each other without interactive or cooperative play. Solitary play (Choice B) involves a child playing alone, while cooperative play (Choice C) involves children playing together towards a common goal. Competitive play (Choice D) involves activities where children compete against each other.

Correct Answer: A

Rationale: In this scenario, the infant is presenting with signs of respiratory distress, as evidenced by the increased work of breathing. Lowering the extremities can help reduce the workload on the diaphragm and improve respiratory mechanics. This action can be beneficial in optimizing the infant's breathing before considering more invasive interventions. Option B, initiating positive pressure ventilations, should be considered if the infant's condition deteriorates further and not as the first step. Option C, placing a nasopharyngeal airway and increasing oxygen flow, is not indicated as the primary intervention for increased work of breathing. Option D, listening to the lungs with a stethoscope, may provide additional information but is not the most urgent action needed in this situation.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial as certain foods and additives can affect ADHD symptoms. Ensuring a balanced diet can help manage symptoms and provide proper nutrition. Assessing sleep patterns (Choice A) is also important, but dietary intake is more directly linked to symptom management in ADHD. Academic performance (Choice C) and behavior at home (Choice D) may be affected by ADHD but are not as directly related to medication management as dietary intake.

Correct Answer: A

Rationale: For a 4-year-old child scheduled for a myringotomy, explaining the procedure in simple terms is essential in helping the child understand what will happen during the surgery and reducing anxiety. Encouraging fluid intake, allowing the child to play with medical equipment, and using play therapy are not directly related to preparing the child for the myringotomy procedure. Therefore, these options are incorrect and not as beneficial as explaining the procedure in simple terms.
