Correct Answer: C

Rationale: Circumoral cyanosis should alert the nurse to perform a further assessment because it may indicate inadequate oxygenation or circulation, potentially related to cardiac or respiratory issues. Flat occiput (choice A) is a common finding in infants and is not typically concerning. Small, low-set ears (choice B) are common in Down syndrome and not specifically indicative of an acute issue requiring immediate further assessment. Protruding furrowed tongue (choice D) is also commonly seen in infants with Down syndrome and typically does not warrant immediate further assessment unless associated with other concerning signs or symptoms.

Correct Answer: C

Rationale: When teaching an adolescent with type 1 diabetes about dietary management, it is crucial to ensure a ready source of glucose is available. In cases of hypoglycemia, having a quick source of glucose can help raise blood sugar levels rapidly. Option A is not the most critical aspect of dietary management for an adolescent with type 1 diabetes. While it is generally recommended to eat meals at home for better control over food choices, the availability of a ready glucose source takes precedence. Option B, weighing foods on a gram scale, may not be practical for every meal and could be burdensome. Option D, cooking specific foods for the adolescent, is not necessary as the focus should be on the overall dietary plan rather than individualized meals.

Correct Answer: D

Rationale: The correct answer is D: "This is a lifelong problem, and it is recommended that dietary restrictions must be continued." PKU requires a lifelong adherence to a specific diet low in phenylalanine to prevent cognitive and developmental issues. Phenylalanine buildup can lead to irreversible damage, making it crucial for individuals with PKU to maintain dietary restrictions throughout their lives. Choices A, B, and C are incorrect because they do not address the lifelong nature of dietary restrictions necessary for PKU management.

Correct Answer: C

Rationale: Choice C indicates a need for further teaching because not all products are clearly labeled as latex-free. It is essential for the mother to understand that she should not solely rely on product labels to determine latex content. She should be encouraged to verify with manufacturers and consult healthcare providers for accurate information. Choices A, B, and D are correct responses. Wearing a medical alert identification, informing caregivers, and ensuring the boy avoids all contact with latex are crucial steps in managing his sensitivity to latex and preventing potential allergic reactions.

Correct Answer: A

Rationale: In Friedman's structural functional theory, the affective function of a family involves meeting the love and belonging needs of each member. This includes emotional support, care, and connections that contribute to the overall well-being of the family unit. Choice B is incorrect as it pertains more to the socialization function of the family, where children learn societal roles. Choice C relates to the economic function of the family, ensuring resources are available and allocated appropriately. Choice D focuses on the instrumental function of the family, which involves meeting the physical needs and health of its members.
