HESI A2 Practice Vocabulary
1. What does Dilute mean?
- A. To concentrate
- B. To make a liquid less concentrated
- C. To solidify
- D. To evaporate
Correct answer: B
Rationale: The correct definition of dilute is to make a liquid less concentrated. When a substance is diluted, it means it has been mixed with another substance to reduce its strength or concentration. Option A, 'To concentrate,' is the opposite of dilute. Option C, 'To solidify,' means to make or become hard or solid, which is unrelated to diluting a liquid. Option D, 'To evaporate,' means to change from a liquid to a vapor, also unrelated to diluting a liquid. Therefore, the correct answer is B.
2. What is the best description of aseptic?
- A. Infected
- B. Purified
- C. Contaminated
- D. Sterilized
Correct answer: B
Rationale: The correct answer is B: 'Purified.' Aseptic means free from contamination or purified. In medical and scientific contexts, aseptic techniques are used to prevent contamination and maintain sterility in environments or procedures. Choice A, 'Infected,' is incorrect as aseptic refers to being free from contamination, not being infected. Choice C, 'Contaminated,' is incorrect as aseptic means the opposite of contaminated. Choice D, 'Sterilized,' is incorrect as aseptic focuses on the absence of contamination rather than the process of sterilization.
3. If you are an assiduous worker, you are probably ____?
- A. Lazy
- B. Industrious
- C. Inconsistent
- D. Procrastinating
Correct answer: B
Rationale: The correct answer is B. If someone is described as assiduous, it means they are diligent, hardworking, and persistent in their efforts. This aligns with the trait of being 'Industrious.' Choices A, C, and D are incorrect because being lazy, inconsistent, or procrastinating are the opposite characteristics of someone who is assiduous.
4. A condition that is ongoing is ___________.
- A. rapid
- B. continuous
- C. partial
- D. complete
Correct answer: B
Rationale: A condition that is ongoing implies that it is happening or existing continuously without interruption. Therefore, the most suitable word to describe such a state is 'continuous.' Choice A, 'rapid,' means fast or quick, which does not convey the idea of ongoingness. Choice C, 'partial,' means incomplete or fragmentary, which is the opposite of ongoing. Choice D, 'complete,' means finished or whole, which also does not align with the concept of ongoing.
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.
