Nursing Elites

1. 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?

• A. Alcoholism
• B. Renal insufficiency
• C. Hypoparathyroidism
• D. Tumor lysis syndrome

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.

2. Which of the following differentiates ulcerative colitis from Crohn's disease?

• A. Crohn's disease primarily affects the left colon and rectum, while ulcerative colitis most often affects the right colon and distal ileum.
• B. Crohn's disease presents with shallow ulcerations, whereas ulcerative colitis presents with a cobblestone appearance of the mucosal lining.
• C. The extent of involvement is noncontiguous and segmented with Crohn's disease, whereas it is contiguous and diffuse with ulcerative colitis.
• D. Crohn's disease has primarily mucosal involvement, whereas it is transmural with ulcerative colitis.

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.

3. Which of the following healthcare providers can legally have access to all, or part, of a patient's medical record because they have a 'need to know'? Select one that does not apply.

• A. Student nurses caring for a particular patient
• B. Registered nurses when they are not caring for a particular patient
• C. The Vice President for nursing who is investigating a patient fall
• D. Licensed practical nurses caring for a particular patient

Correct answer: B

Rationale: Student nurses, licensed practical nurses, the Vice President for nursing investigating a fall, and quality assurance nurses have a 'need to know' basis to access patient records. Registered nurses who are not directly involved in the care of a patient do not have a legitimate reason or 'need to know' to access that patient's medical records, making choice B the correct answer. The Vice President for nursing investigating a specific incident and licensed practical nurses directly involved in a patient's care have legitimate reasons to access the medical records, ensuring continuity and quality of care.

4. A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a sodium level of 130 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a sodium value at this level?

• A. The client with renal failure
• B. The client who is taking diuretics
• C. The client with hyperaldosteronism
• D. The client who is taking corticosteroids

Correct answer: B

Rationale: The correct answer is B. Clients taking diuretics are at risk for hyponatremia due to excessive sodium loss. In this scenario, a sodium level of 130 mEq/L indicates hyponatremia, which is commonly associated with diuretic use. Options A, C, and D are not the highest risk factors for developing low sodium levels in this context. Renal failure, hyperaldosteronism, and corticosteroid use are not directly linked to sodium loss as seen with diuretics.

5. Which of the following actions can an individual nurse take to exert leadership in supporting the profession of nursing?

• A. Join a local professional organization.
• B. Talk about healthcare issues to everyone who will listen, including legislators.
• C. Register to vote.
• D. Learn about the healthcare system.

Correct answer: B

Rationale: Engaging in conversations about healthcare issues with a wide audience, including legislators, is a powerful way for a nurse to exert leadership and support the nursing profession. This action helps raise awareness, advocate for nursing-related matters, and contribute to positive changes in healthcare policies. Choice A, joining a local professional organization, is beneficial but may not have the same broad impact as engaging in public discourse. Choice C, registering to vote, is important for civic engagement but does not directly relate to exerting leadership in supporting the nursing profession. Choice D, learning about the healthcare system, is valuable for personal development but does not directly address exerting leadership in supporting the nursing profession.
