Vocabulary for HESI A2

1. What does Redundancy mean?

A. Deficiency
B. Surplus
C. Delicate
D. Abundance

Correct answer: B

Rationale: Redundancy means having more than is needed, making 'Surplus' the correct choice. The term does not relate to 'Deficiency' (lack), 'Delicate' (fragile), or 'Abundance' (plenty). In the context of this question, Redundancy refers to an excess or surplus of something.

2. What does 'Cease' mean?

A. Start
B. Come to an end
C. Pause
D. Skip

Correct answer: B

Rationale: The correct answer is B: 'Come to an end.' Cease means to stop or come to an end. Choice A, 'Start,' is the opposite of what Cease means. Choice C, 'Pause,' implies a temporary stop, which is not the same as coming to an end. Choice D, 'Skip,' means to omit or bypass, which is different from the meaning of Cease.

3. Hypothetical is best defined as being ___________.

A. rigorous
B. short-term
C. assumed
D. convinced

Correct answer: C

Rationale: Hypothetical is best defined as being assumed because it describes something that is based on a theory or assumption rather than solid proof or certainty. Hypothetical situations are used to explore different possibilities or outcomes without being confirmed as true or existing. Choice A, 'rigorous,' does not accurately define hypothetical, as it refers to something that is extremely thorough, accurate, or carefully done. Choice B, 'short-term,' is unrelated to the definition of hypothetical. Choice D, 'convinced,' does not capture the essence of hypothetical, which is more about assumptions and possibilities rather than being convinced of something.

4. Choose the meaning of the word vent in the following sentence: 'A tube is used to vent the gases to the outside.'

A. Block
B. Trade
C. Emit
D. Inhale

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off. 'Trade' is incorrect as it refers to the exchange of goods or services. 'Inhale' is incorrect as it means to breathe in, which is the opposite of venting gases out.

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.
