1. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

2. You are teaching students about how hyperosmotic agents (osmotic diuretics) are used to treat intracranial pressure. Which of the following is NOT one of the functions of hyperosmotic agents?

• A. Reduces brain metabolism and systemic blood pressure
• B. Reduces cerebral edema
• C. Dehydrates the brain
• D. Draws fluids from extravascular spaces into the plasma

Correct answer: A

Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.

3. While turning and positioning a bedfast client, the PN observes that the client is dyspneic. Which action should the PN take first?

• A. Apply a pulse oximeter
• B. Measure blood pressure
• C. Notify the charge nurse
• D. Observe pressure areas

Correct answer: C

Rationale: Notifying the charge nurse promptly is the priority when a bedfast client is dyspneic. Dyspnea can indicate a serious problem that requires immediate assessment and intervention. Contacting the charge nurse ensures timely assistance and appropriate actions to address the client's condition. Applying a pulse oximeter or measuring blood pressure may provide valuable data, but the priority is prompt communication with the charge nurse to ensure quick intervention. Observing pressure areas, while important for overall client care, is not the most immediate action needed when a client is experiencing dyspnea.

4. Which of the following components of nutrition has a primary function of helping with tissue growth and repair?

• A. Vitamin D
• B. Vitamin E
• C. Protein
• D. Fat

Correct answer: C

Rationale: Protein is the correct answer as it is essential for tissue growth and repair. Proteins are composed of amino acids, the building blocks of body tissues. While vitamins D and E have important roles in the body, they are not primarily responsible for tissue growth and repair. Fats are crucial for various bodily functions, like providing energy, but they are not the primary component involved in tissue growth and repair.

5. The nurse determines that a client with cirrhosis is experiencing peripheral neuropathy. What action should the nurse take?

• A. Protect the client's feet from injury
• B. Apply a heating pad to affected area
• C. Keep the client's feet elevated
• D. Assess the feet and legs for jaundice

Correct answer: A

Rationale: Protecting the client's feet from injury is essential when managing peripheral neuropathy in a client with cirrhosis. Peripheral neuropathy can result in reduced sensation, increasing the risk of injury. Applying a heating pad or keeping the client's feet elevated would not address the primary concern of preventing injury. Assessing the feet and legs for jaundice is important for monitoring liver function, but it is not directly related to managing peripheral neuropathy in this case.
