1. The primary responsibility for nutrition care of people in the community belongs to the:
- A. community physician.
- B. public health nurse.
- C. public health nutritionist.
- D. registered dietitian.
Correct answer: C
Rationale: Public health nutritionists work within communities to ensure that populations have access to nutritional resources. They focus on promoting good nutrition, developing programs, and educating the public about healthy eating habits. While community physicians, public health nurses, and registered dietitians may also play roles in promoting nutrition in the community, the primary responsibility for nutrition care typically falls under the purview of public health nutritionists.
2. What is one function of essential fatty acids?
- A. improve skin integrity.
- B. control lipid digestion.
- C. reduce blood clotting time.
- D. form chylomicrons.
Correct answer: A
Rationale: Essential fatty acids play a crucial role in improving skin integrity by supporting the structure and function of cell membranes. This helps in maintaining healthy skin and promoting overall well-being. The other choices are incorrect because essential fatty acids do not directly control lipid digestion, reduce blood clotting time, or form chylomicrons.
3. Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?
- A. Fructose.
- B. Galactose.
- C. Sucrose.
- D. Maltose.
Correct answer: B
Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk. Fructose is a monosaccharide found in fruits and honey. Sucrose is a disaccharide composed of glucose and fructose, commonly known as table sugar. Maltose is a disaccharide formed by the combination of two glucose molecules.
4. What triggers the release of cholecystokinin (CCK)?
- A. Presence of food in the stomach.
- B. Presence of fat in the duodenum.
- C. Entry of acid chyme into the ileum.
- D. Entry of bile into the gallbladder.
Correct answer: B
Rationale: The correct answer is B: Presence of fat in the duodenum. Cholecystokinin (CCK) is released in response to the presence of fat in the duodenum to aid in digestion by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Options A, C, and D are incorrect because CCK is specifically released in response to the presence of fat in the duodenum, not food in the stomach, acid chyme in the ileum, or bile in the gallbladder.
5. Which pathogenic bacterium is associated with peptic ulcer disease and gastric cancer?
- A. Lactobacillus.
- B. Bifidobacterium.
- C. H. pylori.
- D. E. coli.
Correct answer: C
Rationale: The correct answer is H. pylori. This bacterium is known to be associated with the development of peptic ulcers and an increased risk of gastric cancer. Lactobacillus (Choice A) and Bifidobacterium (Choice B) are probiotic bacteria that are beneficial to human health and not associated with causing these conditions. E. coli (Choice D) is a diverse group of bacteria, some of which can be pathogenic, but they are not primarily linked to peptic ulcers and gastric cancer like H. pylori.
