1. Which term describes the amino acids that are synthesized by the body?

Correct answer: B

Rationale: The correct answer is B: nonessential amino acids. Nonessential amino acids can be synthesized by the body, so they do not need to be obtained through the diet. Essential amino acids, choice A, must be obtained from the diet because the body cannot produce them. Choices C and D, complete and incomplete amino acids respectively, do not accurately describe the classification of amino acids based on synthesis by the body.

2. The type of protein-energy malnutrition that results in edema, hypoalbuminemia, skin lesions, and fatty liver is:

Correct answer: C

Rationale: The correct answer is C, kwashiorkor. Kwashiorkor is a type of protein-energy malnutrition characterized by edema, hypoalbuminemia, skin lesions, and fatty liver. Edema is a key feature of kwashiorkor due to hypoalbuminemia, which leads to decreased oncotic pressure. Marasmus (choice B) is a form of severe malnutrition characterized by energy deficiency without significant protein deficiency, resulting in severe wasting. Cachexia (choice A) is a syndrome characterized by weight loss, muscle atrophy, fatigue, weakness, and loss of appetite in someone who is not actively trying to lose weight. Sarcopenia (choice D) is the age-related loss of muscle mass and function.

3. Cholecystokinin (CCK) is produced in the:

Correct answer: A

Rationale: Cholecystokinin (CCK) is produced in the duodenum, not the stomach, pancreas, or liver. It is released in response to the presence of food in the duodenum, where it plays a crucial role in regulating digestive processes by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Therefore, the correct answer is the duodenum (Choice A). Choices B, C, and D are incorrect because CCK is not produced in the stomach, pancreas, or liver.

4. In which individual does negative nitrogen balance occur?

Correct answer: D

Rationale: Negative nitrogen balance occurs when the body loses more nitrogen than it gains. This imbalance is often seen in conditions like anorexia in older adults, where insufficient protein intake leads to muscle breakdown and negative nitrogen balance. Choices A, B, and C do not typically lead to negative nitrogen balance as seen in anorexia in older adults.

5. Why is it important to understand standard serving sizes of foods?

Correct answer: C

Rationale: The correct answer is C. Understanding serving sizes is crucial because most people have difficulty estimating the amount of food they eat. It helps individuals accurately track their intake, which is essential for maintaining a healthy diet and avoiding overeating. Choice A is incorrect because the question focuses on portion sizes rather than specific nutrients. Choice B is incorrect as it presents an unsupported claim about serving sizes decreasing. Choice D is incorrect as weighing food portions is not always necessary to check serving sizes; understanding standard serving sizes allows for a more practical approach to portion control.
