1. Which enzyme is most essential for the digestion of triglycerides found in butterfat?

Correct answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.

2. The PACU nurse will maintain postoperative T and A client in what position?

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. Which animal-derived food contains the most significant level of carbohydrates?

Correct answer: C

Rationale: Milk contains the most significant level of carbohydrates among animal-derived foods. Milk and milk products supply significant quantities of carbohydrate in the form of lactose. Eggs, beef, and poultry are not significant sources of carbohydrates compared to milk. In cheese making, lactose is removed as a by-product, reducing the carbohydrate content further.

4. Furosemide (Lasix) is a drug used to _____.

Correct answer: D

Rationale: Furosemide is a diuretic that helps mobilize fluids by increasing urine output, often used to treat conditions like edema and heart failure.

5. Each statement is true of water-soluble vitamins, except one. Which is it?

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.
