Correct Answer: B

Rationale: Puffiness of the face and hands is a classic symptom of hypothyroidism. This occurs due to fluid retention and is commonly observed in individuals with an underactive thyroid gland. Increased appetite and weight loss (Choice A) are more indicative of hyperthyroidism, where there is an overproduction of thyroid hormones leading to increased metabolism. Nervousness and tremors (Choice C) are associated with hyperthyroidism, not hypothyroidism. Thyroid gland swelling (Choice D) typically indicates goiter, which can be present in both hyperthyroidism and hypothyroidism but is not a specific symptom that clients with hypothyroidism commonly report.

Correct Answer: B

Rationale: Neck vein distention is a sign of fluid overload, a complication of SIADH due to water retention. Tetanic contractions (Choice A) are not typically associated with SIADH. Weight loss (Choice C) is not a common complication of SIADH, as patients often experience fluid retention and weight gain. Polyuria (Choice D) is also not a typical sign of SIADH, as the condition is characterized by water retention and decreased urine output.

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: The correct answer is A: 30 minutes to 1 hour after administration. Rapid-acting insulins like lispro, such as Humalog, peak quickly within 30 minutes to 1 hour after administration. This peak time is crucial to monitor for potential hypoglycemia, which is most likely to occur during this period. Choice B is incorrect as it suggests a longer peak time for rapid-acting insulin, which is inaccurate. Choices C and D are also incorrect because they indicate even longer peak times, which do not align with the rapid onset and peak action of lispro insulin.

Correct Answer: A

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