1. Which insulin has the most rapid onset of action?

• A. Lente
• B. Lispro
• C. Ultralente
• D. Humulin N

Correct answer: B

Rationale: Lispro insulin has the most rapid onset of action among the options provided. It is a rapid-acting insulin analog that is designed to control postprandial hyperglycemia effectively. Lente insulin (Choice A) and Ultralente insulin (Choice C) are intermediate-acting insulins, which have a slower onset of action compared to Lispro. Humulin N (Choice D) is a neutral protamine Hagedorn (NPH) insulin, which is an intermediate-acting insulin, not rapid-acting like Lispro. Therefore, the correct choice is Lispro.

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. A nurse is caring for a client who requests information about the prevalence of Tay-Sachs disease. Which of the following resources should the nurse use to obtain this information?

• A. The client's health care provider
• B. A collaborative, user-edited website
• C. The facility's case manager
• D. An evidence-based nursing journal

Correct answer: D

Rationale: An evidence-based nursing journal is the correct choice for the nurse to obtain information about the prevalence of Tay-Sachs disease. These journals contain peer-reviewed research and studies conducted by experts in the field, providing accurate and reliable information. Choice A, the client's health care provider, may have general information but may not provide detailed prevalence data. Choice B, a collaborative, user-edited website, is not a reliable source as the information may be inaccurate or outdated. Choice C, the facility's case manager, is unlikely to have specific prevalence data on Tay-Sachs disease.

4. Your patient has a blood potassium level of 9.2 mEq/L. What intervention should you anticipate for this patient?

• A. Intravenous potassium supplementation
• B. Intravenous calcium supplementation
• C. Kidney dialysis
• D. Parenteral nutrition

Correct answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.

5. A nurse is supervising an assistive personnel (AP) who is feeding a client who has dysphagia. Which of the following actions by the AP should the nurse identify as correct technique?

• A. Elevating the head of the client's bed to 30 degrees during mealtime
• B. Withholding fluids until the end of the meal
• C. Providing a 10-minute rest period prior to meals
• D. Instructing the client to place her chin toward her chest when swallowing

Correct answer: D

Rationale: The correct technique for a client with dysphagia is to instruct them to place their chin toward their chest when swallowing. This action helps to close off the airway during swallowing, reducing the risk of aspiration. Elevating the head of the client's bed to 30 degrees during mealtime helps prevent aspiration, but this is not the responsibility of the AP. Withholding fluids until the end of the meal can lead to dehydration and is not a recommended practice. Providing a 10-minute rest period prior to meals is not specifically related to improving swallowing safety for clients with dysphagia.
