Correct Answer: A

Rationale: The correct answer is A. Ketones in the urine may indicate infection or blockage in the urinary catheter, necessitating irrigation to ensure proper drainage. Choice B, an unusual odor in the urine, may suggest infection but does not directly indicate the need for catheter irrigation. Choice C, a high urine specific gravity, is indicative of concentrated urine but does not specifically point to the need for catheter irrigation. Choice D, a bladder scan showing 525 mL of urine, indicates urine retention, which may require catheterization or further assessment but not necessarily irrigation.

Correct Answer: A

Rationale: The correct answer is A. During medication reconciliation, the nurse should compare the client's home medications with the provider's prescriptions to ensure accurate and safe administration. This process helps identify any discrepancies or potential interactions. Choice B is incorrect because placing the client's home medication bottles in a secure location is not part of medication reconciliation. Choice C is incorrect as calling the pharmacy to determine medication availability is not related to reconciling medications. Choice D is incorrect as verifying the client's name on their identification bracelet with the medication administration record is part of the identification process, not medication reconciliation.

Correct Answer: C

Rationale: The correct answer is C: 'To empower patients to take control of their health.' Patient education aims to provide individuals with the knowledge and skills necessary to actively participate in managing their health conditions. Choice A, 'To enhance clinical skills,' is incorrect as patient education focuses on empowering patients, not enhancing healthcare providers' skills. Choice B, 'To ensure patient safety,' is incorrect because while patient safety is crucial, the primary goal of patient education is to empower patients. Choice D, 'To improve patient compliance,' is also incorrect as the main aim is to empower patients to make informed decisions and take an active role in their healthcare.

Correct Answer: B

Rationale: The correct answer is 'B' - as soon as possible. Patients with type 2 diabetes should have a dilated eye exam shortly after diagnosis to check for any signs of diabetic retinopathy, a common complication of diabetes. Waiting for 2 years (choice A) may lead to missing early signs of eye damage. Choice C is incorrect as there is no specific age requirement mentioned for the eye exam. Choice D is also incorrect because early detection and intervention are crucial in diabetic eye disease.

Correct Answer: D

Rationale: Cultural diversity presents an important challenge to nurse managers due to the increase in cultural diversity seen both in the patient population and the nursing staff. This challenge requires nurse managers to ensure that their nursing staff can effectively communicate and provide culturally competent care to patients from diverse backgrounds. Choice A is incorrect because it does not directly relate to the impact of cultural diversity. Choice B is incorrect as it focuses on the training of staff nurses rather than the overall challenge of managing cultural diversity. Choice C is incorrect as the percentage of nursing staff from minority groups, while important, is not the primary reason cultural diversity poses a challenge to nurse managers.
