1. Each of the following is a form of vitamin K, except one. Which is the exception?

• A. Phylloquinone
• B. Tocopherol
• C. Menaquinone
• D. Menadione

Correct answer: B

Rationale: Tocopherol, Choice B, is not a form of vitamin K; it is another name for vitamin E. Phylloquinone (Choice A), menaquinone (Choice C), and menadione (Choice D) are all forms of vitamin K. Phylloquinone is vitamin K1 found in green plants, menaquinone is vitamin K2 produced in the large intestine and found in animal tissues, and menadione is a synthetic form of vitamin K. Therefore, Choice B is the correct answer because it does not belong to the vitamin K group, unlike the other options.

2. What dietary factor raises triglyceride levels?

• A. high refined carbohydrate intake
• B. low soluble fiber intake
• C. high iron intake
• D. low fat intake

Correct answer: A

Rationale: The correct answer is A: high refined carbohydrate intake. High intake of refined carbohydrates, such as sugars and white flour, can lead to elevated triglyceride levels, increasing the risk of cardiovascular disease. Choice B, low soluble fiber intake, is incorrect because soluble fiber actually helps lower triglyceride levels. Choice C, high iron intake, is incorrect as iron intake is not directly linked to raising triglyceride levels. Choice D, low fat intake, is also incorrect as not all fats raise triglyceride levels; it depends on the type of fat consumed.

3. What is the medical term for a persistent, abnormal distortion of taste?

• A. Anosmia
• B. Dysgeusia
• C. Xerostomia
• D. Hypogeusia

Correct answer: B

Rationale: The correct answer is Dysgeusia, which is a persistent and abnormal distortion of the sense of taste. This condition can be triggered by various factors such as medications or certain diseases. Anosmia, choice A, refers to the loss of the sense of smell, not taste. Xerostomia, choice C, is the medical term for dry mouth, which is not specifically related to a distortion of taste. Hypogeusia, choice D, refers to a reduced ability to taste things, which is not the same as a distortion of the sense of taste.

4. What is the function of the gallbladder?

• A. to store bile
• B. to produce bile
• C. to digest bile
• D. to modify bile to a liquid form

Correct answer: A

Rationale: The correct answer is A: "to store bile." The gallbladder acts as a reservoir for bile produced by the liver. It releases bile into the small intestine to aid in the digestion of fats. Choice B is incorrect because the liver produces bile, not the gallbladder. Choice C is incorrect as the gallbladder does not digest bile but stores and releases it for digestion. Choice D is incorrect because bile is already in liquid form; the gallbladder does not modify it to a liquid state.

5. Which of the following is a normal change observed in an elderly individual?

• A. Enhanced sense of taste
• B. Increased appetite
• C. Frequent urination
• D. Lens thinning

Correct answer: C

Rationale: The correct answer is C, frequent urination. As people age, they may experience physiological changes that can lead to an increased frequency of urination. This is due to a decrease in bladder capacity and increased bladder irritability, which are normal age-related changes. On the contrary, the sense of taste (Choice A) and appetite (Choice B) often decrease with age, not increase. As for Choice D, the lens of the eye actually thickens with age, not thins, leading to conditions like presbyopia. Therefore, Choices A, B, and D are incorrect.
