Correct Answer: A

Rationale: When introducing a new policy on the unit, it is essential for the nurse manager to involve staff members in the decision-making process. This approach helps in gathering input and insights from the team, fostering a sense of ownership and commitment. By communicating the reasons behind the policy change, the nurse manager ensures transparency and promotes understanding among the staff, leading to buy-in and acceptance of the new policy. Choice B is incorrect because implementing a policy change without involving staff and explaining the rationale may lead to resistance or lack of understanding. Choice C is not ideal as delegation without active involvement and communication with the team may result in misunderstandings or incomplete implementation. Choice D lacks the crucial step of involving staff in the decision-making process, which is important for successful policy implementation and team engagement.

Correct Answer: C

Rationale: The correct symptom to mention when educating a client with diabetes mellitus (DM) on hypoglycemia is sweating. Sweating is a common symptom of hypoglycemia as it occurs due to the activation of the sympathetic nervous system in response to low blood sugar levels. Increased thirst (Choice A) and frequent urination (Choice B) are more indicative of hyperglycemia (high blood sugar) rather than hypoglycemia. Weight loss (Choice D) is not a typical symptom associated with hypoglycemia.

Correct Answer: C

Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.

Correct Answer: A

Rationale: The correct answer is 'Apples.' Apples are the lowest in potassium among the given options. Carrots, spinach, and avocados are all higher in potassium content compared to apples. Carrots and spinach are vegetables known to have a moderate amount of potassium. Avocados, on the other hand, are a high-potassium fruit and would not be the lowest in potassium among the choices provided.

Correct Answer: B

Rationale: The correct answer is B: Hypoglycemia. When a client with diabetes mellitus is taking oral antidiabetic medication, the nurse should closely monitor for hypoglycemia, which is a common adverse effect. Hypoglycemia occurs when the blood sugar levels drop below normal range, leading to symptoms like confusion, shakiness, and sweating. Weight gain (Choice A) is not a typical adverse effect of oral antidiabetic medications. Hyperglycemia (Choice C) is the opposite of the desired effect of antidiabetic medications, which aim to lower blood sugar levels. Bradycardia (Choice D) is not directly associated with oral antidiabetic medications; it refers to a slow heart rate.
