Correct Answer: A

Rationale: Administering insulin intravenously is the priority action for managing diabetic ketoacidosis. Insulin helps lower blood glucose levels and halts the production of ketones, addressing the underlying cause of ketoacidosis. Giving sips of water (Choice B) may be necessary for hydration, but it does not address the immediate life-threatening issue of ketoacidosis. Monitoring urine output (Choice C) is important for assessing renal function but is not the priority over administering insulin. Applying a heating pad (Choice D) is not indicated and can potentially worsen the condition in ketoacidosis.

Correct Answer: D

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of hyperglycemia, indicating high blood glucose levels. The priority action for the nurse is to check the client's blood glucose levels to assess the severity of hyperglycemia and determine the need for appropriate interventions. Administering insulin (Choice A) may be necessary based on the blood glucose levels but should only be done after confirming the current status. Encouraging increased fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. While monitoring for signs of dehydration (Choice C) is important in the long term, the immediate action should focus on determining the blood glucose levels first.

Correct Answer: B

Rationale: The correct answer is to check the client's blood glucose level. This is the priority action to confirm hypoglycemia before implementing further interventions. Administering glucagon (Choice A) may be necessary in severe cases of hypoglycemia, but confirming the low blood glucose level is crucial before administering any treatment. Giving the client a snack (Choice C) can help raise blood sugar levels but should come after confirming the hypoglycemia. Notifying the healthcare provider (Choice D) is important, but the immediate priority is to assess and address the hypoglycemia.

Correct Answer: A

Rationale: The primary goal of nursing is to assist patients in achieving a peaceful death if recovery is not feasible. This involves providing comfort, dignity, and support during the end-of-life process. Choice B is incorrect because while improving personal knowledge and skills is important, it is not the primary goal of nursing. Choice C, advocating for quality of life over quantity of life, is a valid aspect of nursing care but may not always be the primary goal. Choice D, managing costs to enhance patients' quality of life, is not a primary goal of nursing, as the focus should primarily be on patient care and well-being, rather than financial considerations.
