1. Is the loss of teeth or supporting periodontium often associated with poor food selection and limited chewing ability, and do the patients' masticatory efficiency and biting force decline with each tooth lost?

A. Both statements are true
B. Both statements are false
C. The first statement is true; the second is false
D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are indeed true. The loss of teeth or supporting periodontium frequently leads to poor food selection and limited chewing ability, as these conditions can make certain foods difficult to consume. Additionally, a patient's masticatory efficiency and biting force do decline with each tooth lost, as there are fewer teeth to distribute the force of the bite. Choices B, C, and D are incorrect because they suggest that one or both of these statements are false, which is not the case.

2. Which type of drug is most likely to cause unintentional weight gain?

A. Antiemetics
B. Sedatives
C. Corticosteroids
D. Antibiotics

Correct answer: C

Rationale: Corticosteroids are most likely to cause unintentional weight gain. They influence the metabolism and fat distribution in the body, leading to weight gain. On the other hand, antiemetics are drugs that are used to prevent nausea and vomiting, and they do not typically cause weight gain. Sedatives, while they can cause drowsiness and may lead to less physical activity, are not directly associated with weight gain. Lastly, antibiotics are used to fight bacteria and while they can cause temporary digestive issues, they do not typically result in long-term weight gain.

3. 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.

4. Which lipid contains 3 fatty acids?

A. cholesterol
B. phospholipid
C. saturated
D. triglyceride

Correct answer: D

Rationale: The correct answer is 'D. triglyceride.' Triglycerides are composed of one glycerol molecule and three fatty acids, making them the primary form of stored fat in the body. Cholesterol (A) is a different type of lipid, phospholipids (B) have two fatty acids, and 'saturated' (C) refers to the structure of fatty acids, not a specific lipid containing 3 fatty acids.
