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: During crowning, it is important to apply gentle pressure to the baby's head. This helps to prevent rapid delivery, which can lead to tearing and other complications for both the mother and the baby. Applying pressure also helps to control the delivery process, ensuring a safer and more controlled birth. Choices A, B, and C are incorrect because crowning does not signify the end of the second stage of labor, does not always occur immediately after the amniotic sac ruptures, and it is not safe to transport the patient during crowning, especially if the hospital is nearby, as rapid delivery can occur.

Correct Answer: C

This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

Correct Answer: B

Rationale: For a child with a disorder of the posterior pituitary gland, desmopressin acetate is a medication commonly used to manage the condition by replacing the antidiuretic hormone. Instructing the parents on how to administer desmopressin acetate correctly is essential for the child's care. Choice A is incorrect because growth hormone treatment is not typically used for posterior pituitary disorders. Choice C is incorrect as treatment for this condition usually continues beyond puberty. Choice D is incorrect as acute adrenal crisis is not directly related to a disorder of the posterior pituitary gland.
