1. Which of the following is a critical step in preventing ventilator-associated pneumonia (VAP)?

• A. Performing oral care with chlorhexidine
• B. Elevating the head of the bed to 30-45 degrees
• C. Administering prophylactic antibiotics
• D. Changing the ventilator circuit daily

Correct answer: B

Rationale: Elevating the head of the bed to 30-45 degrees is a critical step in preventing ventilator-associated pneumonia (VAP) because it helps reduce the risk of aspiration, which is a significant factor in the development of VAP. Elevating the head of the bed enhances pulmonary hygiene, decreases the risk of microaspiration, and promotes better lung function. Performing oral care with chlorhexidine is essential for oral hygiene but is not specifically aimed at preventing VAP. Administering prophylactic antibiotics without a clear indication can lead to antibiotic resistance and is not a recommended routine practice to prevent VAP. Changing the ventilator circuit daily is essential for infection control but is not the most critical step in preventing VAP.

2. A client who is receiving chemotherapy has developed stomatitis. Which instruction should the nurse provide the UAP who is assisting with the care of this client?

• A. Keep the room environment free of unpleasant odors
• B. Gather supplies for protective environmental precautions
• C. Assist the client with feeding at meal times
• D. Provide gentle and meticulous mouth care

Correct answer: D

Rationale: Providing gentle and meticulous mouth care is critical for a client with stomatitis as it helps prevent further irritation and infection of the mucous membranes. Keeping the room environment free of unpleasant odors (Choice A) is important for the client's comfort but not directly related to managing stomatitis. Gathering supplies for protective environmental precautions (Choice B) is not relevant to addressing stomatitis. Assisting the client with feeding at meal times (Choice C) is important for overall care but does not specifically target the care needed for stomatitis.

3. Which of the following best describes the role of insulin in the body?

• A. Insulin helps break down glucose into energy for the body
• B. Insulin facilitates the movement of glucose into cells
• C. Insulin converts excess glucose into fat for storage
• D. Insulin increases the breakdown of protein into amino acids

Correct answer: B

Rationale: The correct answer is B: Insulin facilitates the movement of glucose into cells. Insulin is a hormone that helps regulate blood sugar levels by promoting the uptake of glucose from the bloodstream into cells, where it can be used for energy production. Choice A is incorrect because insulin doesn't break down glucose but rather helps cells take up glucose. Choice C is incorrect as insulin does not directly convert glucose into fat; excess glucose is stored as fat by other processes. Choice D is incorrect as insulin does not increase the breakdown of protein into amino acids; its primary role is in glucose metabolism.

4. A client with uterine cancer asks the nurse, 'Which is the most common type of cancer in women?' The nurse replies that it is breast cancer. Which type of cancer causes the most deaths in women?

• A. Breast cancer
• B. Lung cancer
• C. Brain cancer
• D. Colon and rectal cancer

Correct answer: B

Rationale: Lung cancer is the leading cause of cancer-related deaths in women, surpassing even breast cancer. While breast cancer is more common, it is often detected early enough for effective treatment. Lung cancer, on the other hand, tends to be diagnosed at later stages, leading to higher mortality rates. Brain cancer and colon and rectal cancer are not the leading causes of cancer-related deaths in women, making them incorrect choices.

5. What is the primary function of hemoglobin in red blood cells?

• A. Oxygen transport
• B. Immunity
• C. Blood clotting
• D. Carbon dioxide transport

Correct answer: A

Rationale: The correct answer is A: Oxygen transport. Hemoglobin in red blood cells binds to oxygen in the lungs and carries it to tissues throughout the body, releasing it where needed. This process is essential for cellular respiration and energy production. Choices B, C, and D are incorrect because hemoglobin's primary function is not related to immunity, blood clotting, or carbon dioxide transport. Hemoglobin's main role is to transport oxygen, ensuring adequate oxygen supply to body tissues for metabolic processes.
