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.

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. Each of the following foods has cariostatic properties, with one exception. Which food is the exception?

Correct answer: B

Rationale: Cariostatic foods are those that contribute to the prevention of tooth decay. Eggs, cheese, and seafood are all cariostatic foods, as they can aid in protecting against tooth decay. On the contrary, instant oatmeal does not possess these cariostatic properties. Due to its processed nature, it is more fermentable and cariogenic, which means it can encourage cavity formation. Although it is not directly harmful to the teeth, it does not provide the same defensive benefits against tooth decay as the other choices do. Therefore, 'Instant oatmeal' is the exception among these foods and is the correct answer.

3. Starting material for sex hormones:

Correct answer: A

Rationale: Cholesterol is a precursor for the synthesis of sex hormones like estrogen and testosterone.

4. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?

Correct answer: D

Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.

5. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.
