HESI A2 Practice Vocabulary

1. What does 'Occluded' mean?

A. Open
B. Closed or obstructed
C. Partially obstructed
D. Expanded

Correct answer: B

Rationale: The term 'Occluded' means something is closed or obstructed, not open as in choice A. It is more than just partially obstructed as in choice C. It does not mean expanded as in choice D. Therefore, the correct answer is B, 'Closed or obstructed.'

2. Choose the meaning of the word suppress in the following sentence: 'A single dose will suppress even the nastiest cough.'

A. Subdue
B. Cure
C. Restore
D. Affect

Correct answer: A

Rationale: In the sentence, the word 'suppress' is synonymous with the word 'subdue.' To suppress a cough means to reduce or restrain it, which aligns with the meaning of subdue. The other options are incorrect: 'Cure' implies completely eliminating the cough, 'Restore' means to bring back to a former condition, and 'Affect' is too general and does not capture the specific meaning of 'suppress' in this context.

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

A. About it
B. A
C. With
D. Made

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. What does Nebulous mean?

A. Clear
B. Vague
C. Distinct
D. Complex

Correct answer: B

Rationale: The correct answer is B: 'Vague.' Nebulous means something that is vague or unclear. Choices A, C, and D are incorrect because nebulous is the opposite of clear, distinct, and complex. Nebulous refers to something lacking definite form or limits, making it difficult to understand or perceive clearly.

5. Which sentence uses the correct form of the verb?

A. She has completed the project
B. She has completed the project
C. She has been completed the project
D. She has completed the project

Correct answer: B

Rationale: The correct answer is 'She has completed the project.' The sentence uses the present perfect tense with 'has completed,' which is the correct form of the verb. Choice A is incorrect due to the subject-verb agreement error ('She' requires 'has' instead of 'have'). Choice C is incorrect as it changes the meaning by using the passive voice 'has been completed' instead of the active voice. Choice D is incorrect as 'complete' should be 'completed' to match the present perfect tense.
