1. What is a device?

A. An idea or concept
B. A tool or piece of equipment
C. A small part of a larger structure
D. An accessory for fashion

Correct answer: B

Rationale: A device is defined as a tool or piece of equipment designed to serve a specific purpose. It is used to perform a particular function or task. An idea or concept (Choice A) may lead to the creation of a device, but they are not devices themselves. Choice C, referring to a small part of a larger structure, does not encompass the general definition of a device which implies standalone functionality. Choice D, an accessory for fashion, is entirely unrelated to the usual understanding of a device, which focuses on functionality rather than aesthetics.

2. A truculent patient is ______

A. Friendly
B. Argumentative
C. Cooperative
D. Passive

Correct answer: B

Rationale: A truculent patient is characterized by being argumentative or hostile. This type of patient tends to be confrontational and uncooperative, often displaying aggressive behavior. Choice A, 'Friendly,' is incorrect as truculent patients are not known for their friendliness. Choice C, 'Cooperative,' is also incorrect as truculent patients are the opposite of cooperative. Choice D, 'Passive,' is incorrect because truculent patients are not passive but rather assertive and combative.

3. What is another word for PRECAUTION?

A. Rule
B. Routine procedure
C. Preventive measure
D. Habit

Correct answer: C

Rationale: The correct answer is 'C: Preventive measure.' A precaution is a preventive action taken to avoid harm or danger. 'Rule' (A) and 'Habit' (D) do not capture the essence of being cautious to prevent something negative. 'Routine procedure' (B) is related to a regular way of doing things, but it does not specifically imply taking action to prevent harm.

4. HPV is likely to involve the ___________.

A. skull and spine
B. mucous membranes
C. kidneys
D. heart

Correct answer: B

Rationale: HPV, which stands for Human Papillomavirus, is a virus that commonly affects the skin and mucous membranes. It primarily targets the genital area but can also infect the mouth and throat through oral-genital contact. Therefore, the most likely involvement of HPV is with the mucous membranes, making option B the correct choice. Choices A, C, and D are incorrect because HPV does not typically affect the skull, spine, kidneys, or heart.

5. 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.
