Vocabulary HESI A2 Practice Test

1. What does it mean if a theory is obsolete?

A. Advanced
B. Outdated
C. Useful
D. Innovative

Correct answer: B

Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice. Choice A, 'Advanced,' is incorrect as it implies progression rather than obsolescence. Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated. Choice D, 'Innovative,' is incorrect as it suggests newness and originality, which are opposite to being obsolete.

2. What is the term for the lower surface of a structure?

A. Inferior
B. Transverse
C. Dorsal

Rationale: The correct answer is 'Ventral' because it specifically refers to the lower surface of a structure. 'Inferior' means below in position, 'Transverse' means situated across something, and 'Dorsal' refers to the upper side or back of a structure, making them incorrect in the context of the lower surface of a structure.

3. What does Distended mean?

4. 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.

5. Which of the following sentences is written in the passive voice?

A. The homework was completed by the student
B. The student completed the homework
C. The teacher is grading the papers
D. The store opens at 9 AM

Correct answer: A

Rationale: The correct answer is A: 'The homework was completed by the student.' This sentence is in the passive voice because the subject (homework) is being acted upon by the student. In passive voice constructions, the subject receives the action rather than performing it. Choices B, C, and D are in active voice where the subject performs the action. In choice B, 'The student completed the homework,' the subject (student) is the one performing the action of completing the homework.
