Rationale: To improve retention of newly hired nurses, the nurse manager should focus on building their own leadership skills and relationships with staff members.

Rationale: Monitoring blood glucose levels closely before surgery is the priority for a client with diabetes mellitus. This allows for early detection of any abnormalities and helps prevent hypo- or hyperglycemia complications that can arise during the perioperative period. Option A is incorrect because insulin dosing should be individualized based on the client's current blood glucose levels and the surgical plan. Option B is incorrect as abruptly holding oral hypoglycemic agents can lead to uncontrolled blood glucose levels. Option D is incorrect as adequate fluid intake is important for the client's hydration status and overall well-being before surgery.

Correct Answer: A

Rationale: The client with hyperthyroidism should avoid foods high in iodine, as it can exacerbate the condition by increasing thyroid hormone production. Seafood, particularly ocean fish, is rich in iodine, making it a food to avoid. Spinach, bananas, and oatmeal do not contain high levels of iodine and are generally safe for individuals with hyperthyroidism.

Correct Answer: C

Rationale: NPH insulin typically peaks 4-12 hours after administration, so a peak between 1530 and 2130 would be expected. Choice A (1130 and 1330) is too early for the peak effect of NPH insulin. Choice B (1330 and 1930) falls within the possible peak period but is not as accurate as choice C. Choice D (1730 and 2330) is too late for the peak effect of NPH insulin based on the typical peak timing.

Correct Answer: B

Rationale: Motivation theory explains that individuals act based on what they want to achieve, focusing on goals and desires. In this scenario, the healthcare professional's emphasis on improving multitasking skills and problem-solving aligns with the essence of motivation theory. Emotional intelligence primarily pertains to understanding and managing emotions, not specifically related to multitasking and problem-solving. Situational leadership theory emphasizes adapting leadership styles based on the situation and followers, not directly related to individual focus improvement. Transformational leadership theory focuses on inspiring and motivating followers to achieve common goals rather than individual task management and problem-solving skills.
