Nursing Elites

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 factor in a client’s health history increases their risk for cancer?

• A. Family history and environment
• B. Alcohol and smoking
• C. Alcohol consumption and smoking
• D. Proximity to an electric plant and water source

Correct answer: B

Rationale: The correct answer is 'Alcohol and smoking.' Both alcohol consumption and smoking are well-known risk factors for various types of cancer. They have a synergistic effect, meaning their combined impact raises the risk significantly. Family history and environment (Choice A) may play a role in certain cancers, but alcohol and smoking are more directly linked to increased cancer risk. Proximity to an electric plant and water source (Choice D) is not typically associated with an increased risk of cancer compared to alcohol and smoking.

3. Which of the following goals is the most important for the nurse to address for a client admitted to the cardiac rehabilitation unit?

• A. Reduction of anxiety
• B. Referral to community resources
• C. Identification of lifestyle changes
• D. Verbalization of energy-conservation techniques

Correct answer: C

Rationale: The most important goal for a client admitted to the cardiac rehabilitation unit is the identification of lifestyle changes. This is crucial in promoting cardiovascular health and preventing future cardiac issues. Lifestyle changes such as diet modifications, exercise routines, smoking cessation, and stress management play a significant role in improving the overall cardiovascular well-being of the patient. While reducing anxiety, referring to community resources, and verbalizing energy-conservation techniques are all important aspects of care, identifying lifestyle changes is the primary focus in helping the client achieve long-term cardiovascular wellness.

4. 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.

5. A client is going to have an endoscopy performed. Which of the following is not a probable reason for an endoscopy procedure?

• A. Aspiration noted on a honey-thick diet
• B. Pain felt during a bowel movement
• C. Pain felt in the left upper quadrant
• D. Right shoulder pain

Correct answer: B

Rationale: The correct answer is 'Pain felt during a bowel movement.' Endoscopy is used to examine the upper gastrointestinal tract, which includes the esophagus, stomach, and duodenum. Pain during a bowel movement would suggest an issue in the lower gastrointestinal tract, which is typically examined with a colonoscopy. Choices A, C, and D are not probable reasons for an endoscopy procedure as they relate to symptoms in the upper gastrointestinal tract or are not specific to gastrointestinal issues. Aspiration noted on a honey-thick diet could indicate a risk of aspiration pneumonia related to swallowing difficulties, which can be assessed through an endoscopy. Pain felt in the left upper quadrant may be related to conditions like gastritis or peptic ulcers that can be investigated using an endoscopy. Right shoulder pain can be a referred pain from conditions like gallbladder disease that can also be evaluated with an endoscopy.
