Correct Answer: B

Rationale: The correct answer is B: Evidence-based practice. Evidence-based practice relies on research to guide clinical decisions, mirroring the approach of research-based practice. Choice A, Best practices, refers to established methods or techniques that are widely accepted as superior. Choice C, Benchmark practices, typically involves setting standards or goals for performance comparison. Choice D, Standard-based practice, usually pertains to adhering to established norms or guidelines.

Correct Answer: C

Rationale: All staff members should document the care they provided as part of their accountability and to ensure accurate and comprehensive records. In healthcare settings, it is essential for all staff to document the care they deliver for continuity of care and legal purposes. The registered nurse may sign off on the documentation for oversight purposes, but the responsibility of documenting care extends to all staff involved in patient care. Choices A and B incorrectly limit the responsibility to specific roles, while choice D inaccurately suggests that only the registered nurse signs off on the documentation, overlooking the importance of comprehensive documentation by all staff members involved.

Correct Answer: A

Rationale: The correct answer is to check the client's serum glucose level. In a client with diabetes who just had surgery, monitoring the serum glucose level is crucial to ensure proper management of the condition. This helps in preventing complications related to blood sugar fluctuations. Assisting the client out of bed may be important but not the primary responsibility at this time. Placing the client in a high-Fowler's position or ensuring the residual limb is elevated are important interventions for comfort and circulation but are not the primary concern in this scenario.

Correct Answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

Correct Answer: C

Rationale: The correct answer is C. Crohn's disease is characterized by noncontiguous, segmented involvement, meaning it can affect different areas with healthy tissue in between, while ulcerative colitis involves continuous areas of inflammation. Choices A, B, and D are incorrect because Crohn's disease can affect any part of the digestive tract from mouth to anus, can present with shallow ulcerations or deep fissures, and is transmural, meaning it affects the entire thickness of the bowel wall. On the other hand, ulcerative colitis typically affects the colon and rectum, presents with a continuous pattern of inflammation, and primarily involves the mucosal lining of the colon.
