Nursing Elites

1. A clinical instructor teaches a class for the public about diabetes mellitus. Which individual does the nurse assess as being at highest risk for developing diabetes?

• A. The 50-year-old client who does not engage in any physical exercise
• B. The 56-year-old client who drinks three glasses of wine daily
• C. The 42-year-old client who is 50 pounds overweight
• D. The 38-year-old client who smokes one pack of cigarettes daily

Correct answer: C

Rationale: The 42-year-old client who is 50 pounds overweight is at the highest risk for developing diabetes. Excess weight is a significant risk factor for diabetes as it can lead to insulin resistance and metabolic abnormalities. Choices A, B, and D are also risk factors for diabetes, but being overweight has a stronger association with the development of the condition compared to lack of exercise, excessive alcohol consumption, or smoking.

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 is a benefit of the U.S. health-care system?

• A. With cost savings from technology, more Americans now have health-care insurance.
• B. Quality of care has improved in the United States.
• C. Care in the United States has shifted to a prevention focus rather than an illness focus.
• D. The use of technology is projected to decrease health-care costs and improve clinical outcomes.

Correct answer: D

Rationale: The correct answer is D because the use of technology and electronic health records is projected to decrease health-care costs and improve clinical outcomes, quality, and safety. Choice A is incorrect because it states that very few Americans have no health-care insurance, which is not a benefit of the U.S. health-care system. Choice B may be true, but it does not directly address a benefit of the health-care system. Choice C is not necessarily a benefit but rather a shift in focus, so it is also incorrect.

4. A nurse in the emergency department is preparing to care for a client who arrived via ambulance. The client is disoriented and has a cardiac arrhythmia. Which of the following actions should the nurse take?

• A. Proceed with treatment without obtaining written consent
• B. Contact the client's next of kin to obtain consent for treatment
• C. Have the client sign a consent for treatment
• D. Notify risk management before initiating treatment

Correct answer: A

Rationale: In emergency situations where a client is disoriented and has a cardiac arrhythmia, obtaining written consent may not be possible due to the urgency of the situation. The priority is to provide immediate treatment to ensure patient safety. Contacting the next of kin or having the client sign a consent form would cause unnecessary delays in providing critical care. Notifying risk management before initiating treatment is not the most appropriate action when dealing with a time-sensitive situation like a cardiac arrhythmia.

5. 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.
