A nurse reviews a client's laboratory report and notes that the client's serum phosphorus level is 2.0 mg/dL. Which condition most likely caused this serum phosphorus level?

Correct Answer: A

Rationale: The correct answer is A: Alcoholism. Alcoholism can lead to hypophosphatemia due to poor dietary intake and other factors. Excessive alcohol consumption can result in malnutrition, particularly a deficiency in phosphorus. Choices B, C, and D are unlikely to cause low serum phosphorus levels. Renal insufficiency is more likely to cause hyperphosphatemia, hypoparathyroidism is associated with hypocalcemia rather than hypophosphatemia, and tumor lysis syndrome typically presents with hyperphosphatemia due to the release of intracellular phosphate.

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.

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: D

Rationale: The correct answer is D: Psychosocial. Alcohol, caffeine, or drug use are considered psychosocial risk factors as they are related to individual behavior, lifestyle choices, and social interactions. Choices A, B, and C are incorrect. Social demographic factors (choice A) refer to characteristics of a population such as age, gender, education, income, etc. Environmental factors (choice B) include physical surroundings like air quality, housing conditions, etc. Biophysical factors (choice C) involve biological aspects like genetics, physiology, and health conditions.

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.
