1. 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.

2. Select the meaning of the underlined word in the following sentence. Apply the gel on the gingival margin around the selected teeth using the blunt-tipped applicator included in the package.

• A. Edge
• B. Grease
• C. Incisor
• D. Cavity

Correct answer: A

Rationale: In this context, the word 'margin' refers to the border or edge of the gums around the teeth. The gel is supposed to be applied on the gingival margin, which means on the edge or border of the gums near the selected teeth. Choice B, 'Grease,' is incorrect as it does not relate to the application of gel on the gums. Choice C, 'Incisor,' refers to a type of tooth and is unrelated to the context of applying gel on the gingival margin. Choice D, 'Cavity,' is also unrelated as it refers to a decayed area in a tooth and not the border of the gums.

3. What does 'Impaired' mean?

• A. Increased capability
• B. Diminished or lacking usual quality
• C. Hyperactive
• D. Stronger than usual

Correct answer: B

Rationale: The term 'Impaired' means diminished or lacking usual quality. This choice is correct as it accurately reflects the meaning of the word. Choices A, C, and D are incorrect. Choice A, 'Increased capability,' is the opposite of impaired. Choice C, 'Hyperactive,' refers to excessive activity rather than a lack of usual quality. Choice D, 'Stronger than usual,' does not capture the meaning of impaired.

4. What is a nit?

• A. abscess
• B. parasite
• C. bandage
• D. infection

Correct answer: B

Rationale: A nit is a kind of parasite, specifically the egg of a louse. Nits are typically found attached to hair close to the scalp and are commonly associated with head lice infestations. Choice A, 'abscess,' is incorrect as an abscess is a collection of pus caused by an infection. Choice C, 'bandage,' is incorrect as it is a material used for covering wounds. Choice D, 'infection,' is incorrect as it refers to the invasion and multiplication of microorganisms in body tissues.

5. If tubes distend, they ___________.

• A. flex
• B. stretch
• C. solidify
• D. collapse

Correct answer: B

Rationale: When tubes distend, they expand or become enlarged, which typically results in stretching rather than flexing, solidifying, or collapsing. Distending tubes imply an increase in size or volume, indicating a stretching or expansion effect. Therefore, the correct answer is 'stretch.' Choice A, 'flex,' is incorrect as flexing refers to bending or curling, not expanding. Choice C, 'solidify,' is incorrect as solidifying refers to becoming solid, which is not related to the expansion of tubes. Choice D, 'collapse,' is incorrect as collapsing refers to falling in or giving way, which is the opposite effect of distending.
