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.

The doctor has ordered 500 mg of a medication PO once a day. The tablets on hand are labeled as 1 tablet = 250 mg. How many tablets will you administer to your patient?
- A. 1 Tablet
- B. 2 Tablets
- C. 3 Tablets
- D. 4 Tablets
Correct Answer: B
Rationale: To calculate the number of tablets needed, divide the total dosage prescribed (500 mg) by the dosage per tablet (250 mg per tablet). 500 mg / 250 mg per tablet = 2 tablets. Therefore, the correct answer is 2 tablets. Choices A, C, and D are incorrect as they do not accurately reflect the correct calculation based on the provided information.
What is the role of a nurse in patient education?
- A. Providing patients with necessary information to manage their health
- B. Limiting information to prevent confusion
- C. Using complex medical terminology
- D. Discouraging questions from patients
Correct Answer: A
Rationale: The correct answer is A: Providing patients with necessary information to manage their health. Nurses play a crucial role in patient education by offering essential information to help patients understand and manage their health conditions. This empowers patients to make informed decisions about their health and improve their overall well-being. Choices B, C, and D are incorrect. Limiting information would hinder patient understanding and decision-making, using complex medical terminology can confuse patients, and discouraging questions goes against the essence of patient education.
The wound irrigation process cleanses the wound and:
- A. Reduces the potential pain in the wound region or area.
- B. Stops the spread of infection by creating a 'clean' area.
- C. Pushes extravasated blood from a hematoma into nearby healthy tissue.
- D. Allows for the introduction of medications in solution form.
Correct Answer: D
Rationale: The correct answer is D because wound irrigation allows for the introduction of medications in solution form to the wound site. Choice A is incorrect because while wound irrigation can help with pain management indirectly by promoting healing, its primary purpose is not to reduce pain directly. Choice B is incorrect as wound irrigation primarily aims to cleanse the wound and remove contaminants rather than creating a 'clean' area to stop infection spread. Choice C is incorrect because wound irrigation does not involve pushing extravasated blood from a hematoma into nearby healthy tissue; its main goal is to cleanse the wound and promote healing.
Wilms' tumor is a form of:
- A. Renal cancer.
- B. Liver cancer.
- C. Basal cell carcinoma.
- D. Brain cancer.
Correct Answer: A
Rationale: Wilms' tumor is a type of kidney cancer that primarily affects children. The correct answer is A: Renal cancer. This tumor originates in the kidneys and is most commonly found in children, with the peak incidence around 3-4 years of age. Choice B, Liver cancer, is incorrect as Wilms' tumor specifically involves the kidneys, not the liver. Choice C, Basal cell carcinoma, is a form of skin cancer, not related to Wilms' tumor. Choice D, Brain cancer, is incorrect as Wilms' tumor is not associated with the brain but rather with the kidneys.
A nurse is comparing the rate of medication errors on the medical unit to the rate from a medical unit in a magnet hospital. Which of the following quality improvement methods is the nurse using?
- A. Structure audit
- B. Benchmarking
- C. Risk benefit analysis
- D. Root cause analysis
Correct Answer: B
Rationale: The correct answer is B: Benchmarking. Benchmarking involves comparing performance metrics with those from other units or institutions, which is exactly what the nurse is doing by comparing the rate of medication errors on their medical unit to the rate from a medical unit in a magnet hospital. Choice A, Structure audit, is not relevant to this scenario as it focuses on assessing the physical, organizational, or procedural structures in a healthcare setting. Choice C, Risk benefit analysis, involves weighing the potential risks and benefits of a particular course of action, not comparing performance metrics. Choice D, Root cause analysis, is a method used to identify the underlying causes of problems or adverse events, not to compare performance metrics between units.
