1. A common comorbidity in patients with Chronic Kidney Disease (CKD) is:

• A. Liver disease
• B. Malnutrition
• C. Acute renal failure
• D. Difficulty breathing

Correct answer: B

Rationale: Malnutrition is a common comorbidity in patients with Chronic Kidney Disease (CKD). This is mainly due to factors such as dietary restrictions, poor appetite, and the body's increased nutritional needs as it struggles to deal with the disease. Liver disease (Choice A) is not typically associated directly with CKD, although both conditions may coexist in some patients. Acute renal failure (Choice C) is not a comorbidity but a severe and potentially lethal progression of CKD. Difficulty breathing (Choice D) is not a comorbidity but can be a symptom of severe kidney disease or other underlying conditions. However, malnutrition is more commonly observed in CKD patients compared to difficulty breathing.

2. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

3. How many calories does one pound of fat equal?

• A. 1500 calories
• B. 2500 calories
• C. 3500 calories
• D. 5000 calories

Correct answer: C

Rationale: One pound of body fat is equivalent to approximately 3500 calories. This is a generally accepted caloric value used in nutrition and weight management. It's important to note that this is an estimation and individual variations may occur. Choice A (1500 calories), Choice B (2500 calories), and Choice D (5000 calories) are incorrect because they do not match the generally accepted caloric value of 3500 calories for one pound of body fat.

4. Thiamin

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: A

Rationale: Thiamin, or Vitamin B1, plays a crucial role in energy metabolism and the proper functioning of the nervous system.

5. Select all that apply. Which of the following are true about protein digestion?

• A. the end products of protein digestion are amino acids
• B. protein/polypeptides are digested in the large intestine by trypsin
• C. A, D
• D. protein/polypeptides are digested in the stomach by pepsin

Correct answer: C

Rationale: Protein digestion begins in the stomach with the enzyme pepsin, which breaks down proteins into smaller polypeptides. The end products of protein digestion are amino acids.
