Correct Answer: B

Rationale: Assessing the child's coping abilities is appropriate when applying the family stress theory because it helps understand how well the child is managing the stress of the situation. This assessment can provide insights into the child's emotional well-being and resilience, enabling healthcare providers to offer appropriate support. Choices A, C, and D are less relevant in the context of family stress theory. Determining who the decision-maker is may be important but is not directly related to assessing the child's coping abilities. Finding out how siblings feel and explaining procedures to siblings may be valuable aspects of care but are not specifically aligned with the core principles of the family stress theory, which focus on understanding and addressing stress within the family unit.

Correct Answer: B

Rationale: Assessing the child's dietary intake is crucial for managing asthma symptoms as certain foods can trigger or worsen asthma attacks. Monitoring dietary intake helps ensure the child receives proper nutrition and avoids triggers. Assessing sleep patterns (Choice A) may be relevant but not as directly impactful on asthma management. Academic performance (Choice C) and behavior at home (Choice D) are important aspects of a child's overall health but are not as directly related to asthma management as dietary intake.

Correct Answer: C

Rationale: Scheduling the visit at a time that is convenient for the family is the most appropriate choice. This ensures that the family is receptive and available, making the visit more productive. Choice A is incorrect because the presence of the husband may be important for support and decision-making. Choice B focuses solely on the mother and the infant's feeding time, which may not align with the family's overall availability. Choice D is incorrect as it emphasizes the nurse's convenience rather than the family's, which may not lead to an effective visit.

Correct Answer: D

Rationale: The most crucial factor in the process of toilet training is the parents' willingness to consistently engage and work with their child. While parents' attitude and the child's desire to remain dry can influence the process, the key to successful toilet training lies in the parents' commitment and effort. The child's ability to sit still on the toilet is important but not as critical as the parents' active involvement and support in guiding and encouraging the child through the training process.

Correct Answer: B

Rationale: In Addison's disease, adrenal insufficiency leads to decreased aldosterone production. This results in impaired sodium retention and potassium excretion, leading to hyperkalemia. Therefore, the correct answer is hyperkalemia (choice B). Hypernatremia (choice A) is less likely because of the loss of sodium in Addison's disease. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with Addison's disease and are less likely to be present in this condition.
