1. The PEM in which children ages 18-24 months display edema of the extremities, torso, and face, fatty liver, sparse yellow hair, and receive adequate kilocalories but not enough high-quality proteins is called?
- A. Marasmus
- B. Kwashiorkor
- C. Anemia
- D. Noma
Correct answer: B
Rationale: Kwashiorkor is a form of severe malnutrition characterized by edema, fatty liver, and other symptoms, typically resulting from inadequate protein intake despite adequate calorie intake.
2. A nurse is providing teaching about food allergies to the parents of a toddler. Which of the following foods should the nurse identify as highest risk for allergies in toddlers?
- A. Eggs
- B. Milk
- C. Bananas
- D. Citrus fruits
Correct answer: A
Rationale: The correct answer is A: Eggs. Eggs are one of the most common food allergens in toddlers and should be introduced carefully. Milk (choice B) is also a common allergen but is typically introduced earlier in a child's diet. Bananas (choice C) and citrus fruits (choice D) are less likely to cause allergic reactions compared to eggs.
3. Riboflavin
- A. Vitamin B1
- B. Vitamin B2
- C. Vitamin B3
- D. Vitamin B12
Correct answer: B
Rationale: Riboflavin is also known as Vitamin B2, which is important for energy production and the metabolism of fats, drugs, and steroids.
4. To raise HDL levels, what is Mrs. Smith advised to do?
- A. quit smoking
- B. increase dietary sodium
- C. take iron supplements
- D. avoid dairy products
Correct answer: A
Rationale: The correct answer is A: quit smoking. Smoking lowers HDL levels, so quitting smoking is crucial to raising HDL levels. Increasing dietary sodium (choice B) is not linked to raising HDL levels and can have negative effects on cardiovascular health. Taking iron supplements (choice C) is not directly related to increasing HDL levels. Avoiding dairy products (choice D) is not necessary to raise HDL levels; in fact, some dairy products like low-fat options can be part of a heart-healthy diet.
5. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?
- A. Longer exposure leads to an increased risk of demineralization
- B. Longer exposure increases the opportunity for remineralization
- C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
- D. The critical pH at which enamel decalcification occurs is 5.5 or less
Correct answer: B
Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
