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. A paroxysm is a sudden spasm. Another word for this might be ___________.

• A. convulsion
• B. symptom
• C. efficacy
• D. embolism

Correct answer: A

Rationale: The correct answer is A: "convulsion." A paroxysm is defined as a sudden spasm or convulsion. The word "convulsion" specifically refers to a violent and involuntary contraction or spasm of muscles, which aligns perfectly with the description of a paroxysm. On the other hand, choices B, C, and D are incorrect. "Symptom" (B) refers to a manifestation of a condition rather than a physical spasm. "Efficacy" (C) relates to effectiveness or success, not a sudden spasm. "Embolism" (D) refers to the obstruction of a blood vessel, which is unrelated to the concept of a sudden spasm. Therefore, convulsion is the most suitable synonym for a paroxysm in this context.

3. A body part that has atrophied has ______.

• A. Enlarged
• B. Withered
• C. Swollen
• D. Damaged

Correct answer: B

Rationale: The correct answer is 'Withered.' Atrophied means that a body part has wasted away or decreased in size. 'Enlarged' (Choice A) means to make or become larger, which is the opposite of atrophied. 'Swollen' (Choice C) means to become larger or rounder in size, usually due to fluid retention or inflammation, which is not the same as atrophied. 'Damaged' (Choice D) means harmed or injured, but it does not specifically refer to the wasting away or shrinking of a body part.

4. Precipitous is best defined as being ____?

• A. Slow
• B. Swift
• C. Gradual
• D. Delayed

Correct answer: B

Rationale: The correct answer is B: 'Swift.' Precipitous is used to describe something that is steep, sheer, or done suddenly and without careful consideration. For example, a precipitous drop in the stock market. 'Slow' (Choice A), 'Gradual' (Choice C), and 'Delayed' (Choice D) do not align with the meaning of precipitous and are therefore incorrect.

5. Select the meaning of the word 'PRN' in the sentence: 'The nurse gave the patient a PRN medication.'

• A. Pinpoint
• B. Relocate
• C. Eradicate
• D. Reduce

Correct answer: D

Rationale: 'PRN' is a medical abbreviation that stands for 'pro re nata,' meaning 'as needed.' In this context, the medication is given to reduce symptoms as they arise. Choice A, 'Pinpoint,' does not align with the meaning of 'PRN.' Choices B and C, 'Relocate' and 'Eradicate,' are unrelated to the concept of 'as needed' medications.
