1. A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?
- A. Fiber
- B. Vitamin A
- C. Vitamin C
- D. Oxalates
Correct answer: C
Rationale: Vitamin C aids in the absorption of iron by enhancing the body's ability to absorb non-heme iron, which is found in plant-based foods. This vitamin helps convert iron into a form that is more easily absorbed in the intestines. Choices A, B, and D are incorrect because fiber, Vitamin A, and oxalates can actually inhibit the absorption of iron. Fiber can bind to iron and reduce its absorption, Vitamin A does not directly enhance iron absorption, and oxalates found in some foods like spinach and rhubarb can also hinder iron absorption.
2. Sugar alcohols have anticariogenic properties and can protect the teeth by decreasing demineralization, enhancing remineralization, or increasing salivary flow, even in the presence of a fermentable carbohydrate. Name 3 sugar alcohols.
- A. Sorbitol
- B. Mannitol
- C. Xylitol
- D. Erythritol
Correct answer: D
Rationale: Sugar alcohols such as sorbitol, mannitol, and xylitol are commonly used in sugar-free products and have properties that help protect teeth from caries by promoting remineralization and increasing salivary flow. Erythritol is another common sugar alcohol used as a sweetener in various products, but it was not listed in the question.
3. Each of the following is a fat-soluble vitamin except for one. Which is the exception?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin K
Correct answer: B
Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.
4. Digestible carbs are absorbed as ___ through the small intestinal wall and are delivered to the liver, which releases ___ into the bloodstream.
- A. glucose
- B. monosaccharides
- C. galactose
- D. disaccharides
Correct answer: B
Rationale: Digestible carbohydrates are absorbed as monosaccharides (simple sugars) like glucose, which the liver can release into the bloodstream for energy.
5. Of the following neurotransmitters, which demonstrates inhibitory action, helps control mood and sleep, and inhibits pain pathways?
- A. Serotonin
- B. Enkephalin
- C. Norepinephrine
- D. Acetylcholine
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
