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

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.

2. The HCP gives a pregnant woman a prescription for one prenatal vitamin with iron daily and tells her that she needs to increase foods in her diet because her hemoglobin is 8.2 grams/dL. When a list of iron-rich foods is given to the client, she tells the PN that she is a vegetarian and does not eat anything that "bleeds." Which instruction should the PN provide?

Correct answer: A

Rationale: Vegetarians can increase their iron intake through plant-based sources such as green leafy vegetables, oatmeal, and legumes, which are rich in iron.

3. A nurse who receives a patient in the operative suite prior to the actual surgery is in charge of the patient’s care. Which of the following is NOT a task related to the nurse’s intraoperative care?

Correct answer: A

Rationale: The correct answer is A. Going over the surgical procedure with the patient is typically done preoperatively, not intraoperatively. Intraoperative tasks of a nurse involve strictly adhering to asepsis during procedures, monitoring the patient's physical status, and providing emotional support to the patient and their family during the surgery. Choices B, C, and D are all tasks that are directly related to the nurse's responsibilities during the intraoperative phase of care.

4. A client reports being able to swallow only small bites of solid food and liquids for the last 3 months. The PN should assess the client for what additional information?

Correct answer: C

Rationale: The correct answer is C: History of alcohol or tobacco use. A history of alcohol or tobacco use is significant as both are risk factors for esophageal cancer or other esophageal disorders that could cause difficulty swallowing (dysphagia). This information helps in evaluating the underlying cause of the symptom. Choices A, B, and D are less relevant in this context. While a past traumatic injury to the neck could potentially cause swallowing difficulties, given the chronic nature of the symptom in this case, it is more important to focus on potential risk factors associated with esophageal disorders like alcohol and tobacco use. Daily consumption of hot beverages and daily dietary intake of roughage are less likely to be directly related to the client's current swallowing issue.

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

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.
