1. Which enzyme is most essential for hydrolyzing large protein molecules?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

2. Uric acid kidney stones are most commonly associated with what condition?

• A. diabetes
• B. hypercalcemia
• C. gout
• D. diarrhea

Correct answer: C

Rationale: Gout is a condition characterized by high levels of uric acid, which can lead to the formation of uric acid kidney stones due to the crystallization of uric acid in the kidneys.

3. People with only one arm or hand may benefit from using a ____ when eating?

• A. dish with suction cups
• B. rocker knife
• C. utensil holder
• D. flexible straw

Correct answer: B

Rationale: A rocker knife is specifically designed for individuals with limited use of one hand or arm, allowing them to cut food easily. This makes it a suitable option for people with only one arm or hand. Choice A, a dish with suction cups, may not directly aid in cutting food with one hand. Choice C, an utensil holder, is not typically used for cutting food. Choice D, a flexible straw, is more related to drinking liquids and not specifically designed to assist in cutting food one-handed.

4. A patient with an ileostomy is suffering from frequent diarrhea. The clinician should advise the patient to increase his intake of what food to thicken stool output?

• A. celery
• B. salad greens
• C. potatoes
• D. dried beans and peas

Correct answer: C

Rationale: Potatoes are starchy and can help thicken stool output, making them beneficial for patients with an ileostomy experiencing diarrhea.

5. Low levels of high-density lipoproteins (HDL) are?

• A. associated with being underweight
• B. more prevalent in males
• C. highly predictive of CHD risk
• D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.
