1. Which type of cells secrete insulin?
- A. alpha cells
- B. beta cells
- C. CD4 cells
- D. helper cells
Correct answer: B
Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.
2. Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?
- A. open leg fracture
- B. open head injury
- C. stab wound to the chest
- D. traumatic amputation of a thumb
Correct answer: C
Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.
3. The client is taking Antabuse and should avoid eating foods that may trigger a disulfiram reaction. The nurse should instruct the client to avoid:
- A. Peanuts, dates, raisins
- B. Figs, chocolate, eggplant
- C. Pickles, salad with vinaigrette dressing, beef
- D. Milk, cottage cheese, ice cream
Correct answer: C
Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.
4. Which dietary consideration is most important for the nurse to teach to a client with hypothyroidism?
- A. Increase carbohydrate intake
- B. Increase fluid intake
- C. Avoid shellfish
- D. Increase fiber
Correct answer: D
Rationale: The correct answer is to 'Increase fiber.' In hypothyroidism, clients often experience constipation due to decreased metabolic rate. Increasing fiber in the diet can help alleviate constipation. Choice A, 'Increase carbohydrate intake,' is incorrect as there is no specific need to increase carbohydrate intake in hypothyroidism. Choice B, 'Increase fluid intake,' is not directly related to managing hypothyroidism, although adequate hydration is generally important for overall health. Choice C, 'Avoid shellfish,' is commonly associated with hyperthyroidism due to its iodine content, not hypothyroidism.
5. The nurse is teaching a community health class for cancer prevention and screening. Which individual has the highest risk for colon cancer?
- A. Client with irritable bowel syndrome
- B. Family history of colon polyps
- C. Client with cirrhosis of the liver
- D. History of colon surgery
Correct answer: B
Rationale: A family history of colon polyps and/or colon cancer is a significant risk factor for developing colon cancer. Individuals with a family history are more likely to develop colon cancer due to genetic predisposition. While other factors like irritable bowel syndrome, cirrhosis of the liver, and history of colon surgery may contribute to an increased risk of colon cancer, having a family history of colon polyps is the highest risk factor. Irritable bowel syndrome does not directly increase the risk of colon cancer. Cirrhosis of the liver is associated with liver cancer rather than colon cancer. A history of colon surgery may reduce the risk of colon cancer in some cases by removing precancerous polyps.
