1. Protein-energy malnutrition (PEM) may be responsible for the increased incidence of noma and necrotizing ulcerative gingivitis (NUG) because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: The corrected question highlights that protein-energy malnutrition weakens the immune system, making individuals more susceptible to conditions like noma and NUG, which are linked to compromised immunity. Choice A is correct because the statement and reason are both accurate and directly related. Protein-energy malnutrition does result in depressed immune responses, which can predispose individuals to noma and NUG. Choice B is incorrect because the statement and reason are indeed related. Choice C is incorrect as both the statement and reason are accurate. Choice D is also incorrect as the statement is correct and directly supports the reason provided.

2. Which student lunch is the least nutritious?

• A. Ham sandwich, apple, and milk
• B. Hamburger, fries, and soft drink
• C. Macaroni and cheese, green beans, and peaches
• D. Meatloaf, broccoli, and pear slices

Correct answer: B

Rationale: The correct answer is B - 'Hamburger, fries, and soft drink' as it contains foods high in unhealthy fats, sugars, and low nutritional value. A hamburger, fries, and a soft drink are considered less nutritious compared to the other options. Choice A includes a ham sandwich, apple, and milk, which provide a balance of protein, fiber, and calcium. Choice C consists of macaroni and cheese, green beans, and peaches, offering a mix of carbohydrates, vegetables, and fruits. Choice D contains meatloaf, broccoli, and pear slices, which provide a good source of protein, vitamins, and fiber. Therefore, option B is the least nutritious among the given choices.

3. Which of the following actions would be of highest priority with regards to the external shunt?

• A. Avoid taking blood pressure or blood sample from the arm with the shunt
• B. Instruct the patient not to exercise the arm with the shunt
• C. Heparinize the shunt daily
• D. Change the dressing of the shunt daily

Correct answer: C

Rationale: Heparinizing the shunt daily (choice C) is the highest priority action as it prevents the formation of blood clots that can occlude the shunt, leading to potential complications such as thrombosis. Avoiding taking blood pressure or blood samples from the arm with the shunt (choice A) is also important, but secondary to heparinizing the shunt. Similarly, instructing the patient not to exercise the arm with the shunt (choice B) can help prevent unnecessary strain on the shunt, but it is not as critical as preventing clot formation. Changing the dressing of the shunt daily (choice D) is a standard nursing care practice to prevent infection, but again, it is not as critical as ensuring the shunt remains patent through daily heparinization.

4. A nurse is completing an admission assessment on an adolescent client who is a vegetarian. He eats milk products but does not like beans. Which of the following items should the nurse suggest the client order for lunch to provide the nutrients most likely to be lacking in his diet?

• A. Peanut butter and jelly sandwich
• B. Baked potato topped with sour cream
• C. Bagel with cream cheese
• D. Fruit salad

Correct answer: D

Rationale: The correct answer is 'Fruit salad.' Since the adolescent client is a vegetarian who eats milk products but does not like beans, suggesting a fruit salad for lunch would provide essential nutrients like vitamins, minerals, and fiber that are commonly found in fruits. Fruit salad can help supplement the nutrients that may be lacking in his diet. Choices A, B, and C do not offer the same variety and quantity of nutrients as a fruit salad, making them less optimal choices for meeting the client's dietary needs.

5. In a patient with osteoporosis, which mineral is essential to prevent further bone loss?

• A. Iron
• B. Phosphorus
• C. Magnesium
• D. Calcium

Correct answer: D

Rationale: Calcium is crucial in preventing bone loss in patients with osteoporosis.
