1. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
2. A common comorbidity in patients with Chronic Kidney Disease (CKD) is:
- A. Liver disease
- B. Malnutrition
- C. Acute renal failure
- D. Difficulty breathing
Correct answer: B
Rationale: Malnutrition is a common comorbidity in patients with Chronic Kidney Disease (CKD). This is mainly due to factors such as dietary restrictions, poor appetite, and the body's increased nutritional needs as it struggles to deal with the disease. Liver disease (Choice A) is not typically associated directly with CKD, although both conditions may coexist in some patients. Acute renal failure (Choice C) is not a comorbidity but a severe and potentially lethal progression of CKD. Difficulty breathing (Choice D) is not a comorbidity but can be a symptom of severe kidney disease or other underlying conditions. However, malnutrition is more commonly observed in CKD patients compared to difficulty breathing.
3. What is the term for intestinal wounds associated with Crohn's disease that develop in different areas in the intestine, with normal tissue separating affected regions?
- A. Skip lesions
- B. Fistulas
- C. Fissures
- D. Loop ulcerations
Correct answer: A
Rationale: Skip lesions are typical characteristics of Crohn's disease, where patches of diseased intestine are interspersed with areas of healthy tissue. This is why option A is the correct answer. Option B, fistulas, are abnormal connections between two body parts, which is not what the question is describing. Option C, fissures, are small tears in the lining of the anus, which also do not fit the description in the question. Option D, loop ulcerations, is not a recognized medical term, making it an incorrect choice.
4. A healthcare professional is preparing an education program for a group of parents of adolescents. Which of the following should be included as indicators of nutritional risk among adolescents? (Select one that does not apply.)
- A. Skipping more than three meals per week
- B. Eating fast food once weekly
- C. Eating without family supervision frequently
- D. Frequently skipping breakfast
Correct answer: B
Rationale: Among the indicators of nutritional risk among adolescents, skipping meals, eating without family supervision, and frequently skipping breakfast are commonly associated with poor nutrition. However, eating fast food once weekly may not necessarily indicate a significant nutritional risk, as occasional consumption of fast food in moderation is not uncommon among adolescents. This choice is the correct answer because it does not strongly correlate with nutritional risk compared to the other options provided.
5. Which of the following is NOT required on a food label or nutrition facts panel?
- A. Nutrition facts panel
- B. Ingredients in descending order by weight
- C. The % RDA of ALL the vitamins and minerals in the product
- D. Essential warnings, such as common allergies
Correct answer: C
Rationale: According to food labeling regulations, every food label or nutrition facts panel must include a nutrition facts panel, list of ingredients in descending order by weight, and essential warnings such as common allergies. However, it is not mandatory to list the % Recommended Daily Allowance (RDA) of ALL the vitamins and minerals in the product. Only certain vitamins and minerals, deemed significant to public health, are required to be listed. Therefore, the notion that the % RDA of ALL vitamins and minerals must be displayed is incorrect. Choices A, B, and D are required elements on a food label, making them incorrect answers.
