1. Which term is used to describe populations located in lower income, inner city, and rural areas with few supermarkets but numerous small stores stocking limited nutritious food items?
- A. Food fad
- B. Food insecurity
- C. Food desert
- D. Food patterns
Correct answer: C
Rationale: A food desert refers to areas with limited access to affordable and nutritious food, often found in lower-income urban and rural areas.
2. 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.
3. Which mineral is a principal component of cell membranes?
- A. phosphorus
- B. magnesium
- C. iron
- D. iodine
Correct answer: A
Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.
4. What is the most appropriate instruction to provide to the parent of a child who does not like a food item?
- A. The child should not be encouraged to try it again.
- B. The child should be offered a reward if they eat most of the food items.
- C. The child should be offered the item at least 8 times on different occasions.
- D. The child should be encouraged to eat at least 5 bites of the food item.
Correct answer: C
Rationale: The correct answer is C. Encouraging repeated exposure to the food item can help the child develop a taste for it. Option A is incorrect as it suggests avoiding encouraging the child to try the food again, which may hinder their ability to develop a liking for it. Option B is incorrect as using rewards for eating may not promote a genuine interest in the food item. Option D is incorrect because setting a specific number of bites may create pressure and negativity around mealtime, rather than fostering a positive association with the food.
5. After ileostomy, which of the following condition is NOT expected?
- A. Increased weight
- B. Irritation of skin around the stoma
- C. Liquid stool
- D. Establishment of regular bowel movement
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
