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.

Correct Answer: B

Rationale: Choice B is correct because nurses can develop effective leadership skills by actively engaging as good leaders and reflecting on their existing leadership qualities and areas for improvement. This process of self-assessment and continuous improvement is crucial in becoming a successful leader. Choice A is incorrect as leadership traits can be learned through experience and reflection rather than being impossible to acquire from a book. Choice C is incorrect as effective leadership involves focusing on long-term goals and strategies, not just daily activities. Choice D is incorrect because while seizing leadership opportunities is important, it should be done strategically and with a solid foundation of experience in nursing to ensure successful leadership outcomes.

Correct Answer: A

Rationale: Glipizide should be taken 30 minutes before meals to maximize its glucose-lowering effect.

Correct Answer: C

Rationale: Tachycardia is a sign of excessive thyroid hormone replacement. Levothyroxine is used to treat hypothyroidism by supplementing thyroid hormone levels. If a client with hypothyroidism experiences symptoms of tachycardia, it suggests that they may be receiving an excessive amount of levothyroxine, causing hyperthyroidism. Bradycardia (Choice A) is more commonly associated with hypothyroidism, not excessive levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also typical symptoms of hypothyroidism and would not typically indicate overmedication.

Correct Answer: D

Rationale: The correct answer is to instruct the client to inspect their feet daily for any cuts or sores. This is crucial for individuals with diabetes as they are at a higher risk of developing foot problems. Soaking feet daily can lead to skin breakdown and infections, making choice A incorrect. Tight-fitting shoes can cause pressure points and increase the risk of foot injuries, so choice B is incorrect. Applying lotion between the toes can create a moist environment, increasing the risk of fungal infections, making choice C incorrect.
