1. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.

2. Diseases of the heart and blood vessels are collectively referred to as _____.

• A. Coronary artery disease
• B. Cardiovascular disease
• C. Coronary heart disease
• D. Coronary vessel disease

Correct answer: B

Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.

3. Which dietary recommendation is most appropriate for a patient with gout?

• A. Increase protein intake
• B. Reduce carbohydrate intake
• C. Avoid purine-rich foods
• D. Increase calcium intake

Correct answer: C

Rationale: The most appropriate dietary recommendation for a patient with gout is to avoid purine-rich foods. Purine-rich foods such as red meat and shellfish can lead to increased uric acid levels in the body, triggering gout flare-ups. Increasing protein intake (Choice A) is not recommended as some high-protein foods are also high in purines. Reducing carbohydrate intake (Choice B) and increasing calcium intake (Choice D) are not directly related to managing gout symptoms.

4. Which of the following foods should be avoided by patients experiencing xerostomia, except one? Which is the exception?

• A. Saltines
• B. Salsa
• C. Alcohol
• D. Dill pickles

Correct answer: D

Rationale: The correct answer is Dill pickles. Unlike the other choices, which can exacerbate xerostomia due to their dry or irritating nature, dill pickles, being tart and sour, can actually help stimulate saliva flow, which is beneficial for patients with xerostomia. Saltines, salsa, and alcohol are all known to contribute to dry mouth and should generally be avoided by individuals experiencing xerostomia.

5. Proteolytic enzymes are most likely to break down which food type?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.
