1. Amy is a 68-year-old patient who has rheumatoid arthritis affecting her hands and feet. Which substance has been shown to reduce joint tenderness and improve mobility in some people with this type of arthritis?
- A. Alfalfa Tea
- B. Cod Liver Oil
- C. Lecithin
- D. Fish Oil
Correct answer: D
Rationale: Fish oil has been identified as a substance that can help reduce joint tenderness and improve mobility in individuals with rheumatoid arthritis, as it is rich in omega-3 fatty acids. Omega-3 fatty acids have anti-inflammatory properties that can help alleviate the symptoms of rheumatoid arthritis. On the other hand, while Alfalfa Tea, Cod Liver Oil, and Lecithin have various health benefits, there isn't substantial evidence to suggest that they can improve conditions associated with rheumatoid arthritis.
2. Which enzyme is produced by the parotid gland?
- A. Salivary amylase
- B. Sucrase
- C. Maltase
- D. Lactase
Correct answer: A
Rationale: The correct answer is A, Salivary amylase. Salivary amylase is an enzyme produced by the parotid gland that initiates starch digestion in the mouth. It helps break down starch into maltose, a simpler sugar. Choices B, C, and D are incorrect because sucrase, maltase, and lactase are enzymes involved in the digestion of disaccharides like sucrose, maltose, and lactose, respectively, in the small intestine, not in the saliva.
3. People with phenylketonuria should avoid foods made with which nonnutritive sweetener?
- A. acesulfame-K
- B. aspartame
- C. saccharin
- D. sucralose
Correct answer: B
Rationale: People with phenylketonuria should avoid aspartame because it contains phenylalanine, which they cannot metabolize. Acesulfame-K, saccharin, and sucralose do not contain phenylalanine and are safe for individuals with phenylketonuria. Therefore, the correct answer is B. Acesulfame-K, saccharin, and sucralose are incorrect choices because they do not pose a risk for individuals with phenylketonuria due to the absence of phenylalanine in their composition.
4. By the age of three, which age-appropriate food skill can a child typically perform?
- A. Using utensils and a napkin
- B. Spearing food with a fork
- C. Measuring liquids
- D. Displaying proper table manners
Correct answer: B
Rationale: By the age of three, a child typically develops the motor skills needed to spear food with a fork. This is a critical milestone in self-feeding as it shows progress in fine motor coordination. Choice 'A' is incorrect because using utensils and a napkin properly is a skill that may take longer to develop and refine. Choice 'C' is not correct as measuring liquids requires a higher level of motor skills and understanding of quantities that a three-year-old child might not possess. Choice 'D' is also incorrect as the proper display of table manners is a complex skill that is typically learned over a longer period and involves social and cultural norms.
5. Which type of fatty acid has carbon atoms connected by two or more double bonds?
- A. Saturated fatty acids
- B. Monounsaturated fatty acids
- C. Trans fatty acids
- D. Polyunsaturated fatty acids
Correct answer: D
Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.
