1. When people masticate, what do they use?

• A. Fingers
• B. Eyes and ears
• C. Gums and teeth
• D. Heels and toes

Correct answer: C

Rationale: When people masticate, they use their gums and teeth to chew and physically break down food into smaller pieces for easier digestion. The process of mastication is essential for proper digestion in the human body. Choices A, B, and D are incorrect as fingers, eyes, ears, heels, and toes are not involved in the process of chewing or mastication.

2. What is the crystalline compound that is a product of protein metabolism known as?

• A. uracil
• B. urine
• C. ureter
• D. urea

Correct answer: D

Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.

3. The physician started to perform the operation, but the patient was not yet completely _____ anesthesia.

• A. under
• B. within
• C. with
• D. over

Correct answer: A

Rationale: The correct answer is 'under' as it is commonly used to describe the state of being affected by anesthesia. The patient is 'under' anesthesia, not 'within,' 'with,' or 'over' it. 'Within' typically refers to being inside something, 'with' indicates being accompanied by something, and 'over' suggests being above or on top of something. Therefore, in the context of the sentence, 'under' is the most appropriate choice.

4. What is the best description for the abbreviation LDL?

• A. A group of denominations
• B. A type of lipoprotein
• C. Self-care mobility skills
• D. A certain digital value

Correct answer: B

Rationale: The correct answer is B: A type of lipoprotein. LDL stands for Low-density lipoprotein, which is a type of lipoprotein that carries cholesterol through the bloodstream. LDL is often referred to as 'bad' cholesterol because high levels of LDL can lead to plaque buildup in the arteries, increasing the risk of heart disease and stroke. Choices A, C, and D are incorrect as they do not accurately describe the abbreviation LDL.

5. What does the term 'viscous' mean?

• A. Thick and sticky
• B. Slimy
• C. Watery
• D. Dry

Correct answer: A

Rationale: The correct answer is A: 'Thick and sticky.' Viscous describes a substance that is thick and sticky, resisting flow easily. Choices B, C, and D are incorrect. 'Slimy' implies a slippery, gooey texture; 'Watery' describes a substance with a thin, fluid consistency; and 'Dry' indicates the absence of moisture.
