1. What is Diffusion?

• A. Movement of materials from low concentration to high concentration
• B. Movement of materials from high concentration to low concentration
• C. Absorption of nutrients
• D. Breaking of materials

Correct answer: B

Rationale: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and continues until equilibrium is reached. Choice A is incorrect because diffusion occurs down the concentration gradient, from high to low concentration, not from low to high concentration. Choice C is incorrect as it refers to the uptake of substances by cells, not the general process of diffusion. Choice D is incorrect as it does not accurately describe the process of diffusion; diffusion involves the movement of substances, not the breaking of materials.

2. What does concave mean?

• A. Rounded inward
• B. Rounded outward
• C. Straight
• D. Flat

Correct answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

3. 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.

4. What does it mean if a patient is lethargic?

• A. Active
• B. Exhausted
• C. Confused
• D. Restless

Correct answer: B

Rationale: Lethargic means feeling exhausted or sluggish. Being lethargic is the opposite of being active (choice A), confused (choice C), or restless (choice D). When a patient is lethargic, they lack energy and may appear tired or sluggish.

5. An alarm that is strident is ___________.

• A. shrill
• B. muted
• C. constant
• D. resonant

Correct answer: A

Rationale: A strident alarm is loud, harsh, and piercing. The word 'shrill' specifically denotes a high-pitched and piercing sound, which aligns well with the characteristics of a strident alarm. Therefore, 'shrill' is the most suitable answer in this context. Choices B, C, and D are incorrect because a strident alarm is not quiet (muted), unchanging (constant), or deep and full (resonant), but rather loud and harsh.
