HESI A2 Practice Test Vocabulary
1. A paroxysm is a sudden spasm. Another word for this might be
- A. Symptom
- B. Convulsion
- C. Efficacy
- D. Embolism
Correct answer: B
Rationale: The correct answer is B, 'Convulsion.' A paroxysm and a convulsion both refer to sudden, involuntary spasms. This makes 'Convulsion' the most suitable synonym. 'Symptom' (Choice A) refers to an indication of a condition but not a spasm. 'Efficacy' (Choice C) refers to the ability to produce a desired or intended result, unrelated to spasms. 'Embolism' (Choice D) refers to an obstruction in a blood vessel, not a sudden spasm.
2. Which adjective best completes the sentence?
- A. More greater
- B. Great
- C. Best
- D. More greatest
Correct answer: C
Rationale: 'Best' is the correct choice because it conveys the highest quality or degree in comparison, which is appropriate in this context. The sentence is discussing the opinion of coffee experts about a particular coffee blend, indicating that it is the most superior among the options. Choices A, B, and D are grammatically incorrect or redundant. 'More greater' is incorrect due to the redundant use of 'more' and 'greater.' 'Great' is a comparative form that does not fit the superlative context required. 'More greatest' is incorrect due to the unnecessary use of 'more' alongside 'greatest,' which is already a superlative form.
3. Another word for AFFECT is?
- A. Reduce
- B. Contaminate
- C. Eliminate
- D. Influence
Correct answer: D
Rationale: Correct answer: Another word for AFFECT is INFLUENCE. Affect and influence are synonymous when used in the context of producing an effect on something or someone. Choice A, 'Reduce,' is incorrect as it means to make something smaller or lessen its quantity. Choice B, 'Contaminate,' is incorrect as it means to make something impure or harmful. Choice C, 'Eliminate,' is incorrect as it means to completely remove or get rid of something.
4. Which word describes a screen or filter?
- A. Permeable
- B. Incendiary
- C. Exuding
- D. Resilient
Correct answer: A
Rationale: The word 'permeable' refers to a material or surface that allows liquids, gases, or substances to pass through it, while screening or filtering out impurities. This makes it an appropriate descriptor for a screen or filter, which function by allowing certain elements to pass through while retaining others. Choices B, C, and D are incorrect: 'Incendiary' means causing fires, 'Exuding' means giving off or releasing, and 'Resilient' means able to withstand or recover from difficult conditions.
5. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'
- A. Add water to
- B. Reduce by half
- C. Warm up
- D. Decontaminate
Correct answer: A
Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.
