HESI A2 Vocabulary Practice Test

1. What does Vacuous mean?

Correct answer: A

Rationale: The correct answer is A: 'Empty.' Vacuous means lacking intelligence, empty-headed, or devoid of substance. Choice B, 'Full,' is incorrect as it is the opposite of vacuous. Choice C, 'Dense,' means closely compacted or stupid, not vacuous. Choice D, 'Bright,' means giving out or reflecting a lot of light, not vacuous.

2. _____ are very ancient people.

Correct answer: A

Rationale: The correct answer is 'Chinese.' In the context of ancient civilizations, 'Chinese' is appropriately used to refer to a very ancient culture like the Shang dynasty (c. 1600–1046 BC) or the Zhou dynasty (1046–256 BC). The other choices ('The Greeks,' 'Romans,' and 'Egyptians') are also ancient civilizations, but they are not the best fit in the given sentence as they do not match the description of 'very ancient people.' The Greeks, Romans, and Egyptians are ancient too, but 'very ancient people' specifically points towards Chinese civilization during its early periods. Therefore, 'Chinese' is the most suitable option.

3. Which word in the sentence needs to be corrected for proper grammar?

Correct answer: B

Rationale: The word 'A' should be corrected to 'an' in the sentence. The sentence should read, 'The nurse made an error with the medication, so the doctor made notes about it in the patient's file.' The article 'an' is used before a noun beginning with a vowel sound, like 'error' in this case. Choices A, C, and D are grammatically correct in the sentence and do not need to be altered.

4. If a patient’s condition is upgraded, he is ___________.

Correct answer: B

Rationale: When a patient's condition is upgraded, it means that there has been an improvement in their medical status. This change usually indicates that the patient's health is improving or that they are responding well to treatment. Option A, 'getting worse,' is incorrect as an upgrade signifies a positive change. Option C, 'released from the hospital,' does not directly relate to an upgrade in the patient's condition. Option D, 'approved for surgery,' is unrelated to the patient's current medical status and the concept of an upgrade.

5. What does Labile mean?

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).
