HESI A2 Practice Vocabulary

1. What does 'Parameter' mean?

A. A constant variable
B. A characteristic or constant factor
C. A measurable limit
D. A calculated risk

Correct answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.

2. Use the VERB correctly.

A. A pitchfork and a halter were left on the concrete floor.
B. There is a pig, sheep, and horse in the red trailer.
C. Here are the cages for the 2 rabbits and 2 chickens.
D. Sherri and her cousin were at the County fair this year.

Correct answer: D

Rationale: Choice D, 'Sherri and her cousin were at the County fair this year,' is the correct answer. 'Sherri and her cousin' is a compound subject, requiring the plural verb 'were' for proper subject-verb agreement. Choices A, B, and C contain subject-verb agreement errors. In Choice A, 'A pitchfork and a halter' is a compound subject and should be followed by the plural verb 'were.' In Choice B, 'a pig, sheep, and horse' is a list of items that should take the plural verb 'are.' Lastly, in Choice C, 'Here are' should be used instead of 'Here is' to match the plural subject 'the cages for the 2 rabbits and 2 chickens.'

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, 'Industrious.' Assiduous means showing great care and perseverance in your work, which aligns with being industrious. Choice A, 'Lazy,' is incorrect as it is the opposite of assiduous. Choice C, 'Inconsistent,' does not directly relate to being assiduous, and choice D, 'Procrastinating,' suggests delaying tasks which is contrary to being assiduous.

4. To alleviate a symptom is to ___________.

A. relieve it
B. diagnose it
C. suffer from it
D. manage it

Correct answer: A

Rationale: The correct answer is A: 'relieve it.' To alleviate a symptom means to reduce or improve it, thus providing relief or easing of the discomfort or issue being experienced. Choice B, 'diagnose it,' is incorrect as diagnosing a symptom involves identifying or determining its cause, not relieving it. Choice C, 'suffer from it,' is incorrect as it refers to experiencing the symptom, not alleviating it. Choice D, 'manage it,' is incorrect as managing a symptom involves controlling or handling it, not necessarily reducing or relieving it.

5. 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.
