1. Which type of lipid is solid at room temperature?

A. Cholesterol
B. Phospholipid
C. Saturated fat
D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.

2. In managing Type 2 diabetes, what is the most important dietary change?

A. Increase carbohydrate intake
B. Increase fiber intake
C. Increase protein intake
D. Reduce fat intake

Correct answer: B

Rationale: Increasing fiber intake can help regulate blood sugar levels in patients with Type 2 diabetes.

3. What best describes a task of the registered dietitian?

A. administering total parenteral nutrition
B. administering formula through feeding tubes
C. prescribing diet orders
D. conducting nutrition assessments

Correct answer: D

Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.

4. Is it a good idea for an athlete to eliminate all fat from his diet in order to stay lean?

A. yes, because dietary fat is stored easily in fat cells and can't be used for energy
B. no, because fats provide energy during prolonged exercise
C. yes, because fat is stored under the skin and causes the body to overheat
D. no, because excess fat is converted to glycogen and stored in the muscles

Correct answer: B

Rationale: Fat is an essential energy source during prolonged exercise, so eliminating it entirely from the diet is not advisable for athletes.
