Vocabulary HESI A2 Practice Test

1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. Choose the meaning of the word projected in the following sentence: 'Treatment is projected to last three months or more.'

A. Protruded
B. Guaranteed
C. Estimated
D. Alleged

Correct answer: C

Rationale: In this context, 'projected' is used to indicate an estimation or prediction of the duration of the treatment. Therefore, it aligns closest in meaning to 'estimated.' Choice A, 'Protruded,' means to extend beyond or above a surface, which does not fit the context of the sentence. Choice B, 'Guaranteed,' means to provide assurance, which is not the intended meaning in the sentence. Choice D, 'Alleged,' means to claim without proof, which is not the correct interpretation in this context.

3. What is the meaning of Hygiene?

A. General cleanliness and good health practices
B. Measures contributing to cleanliness and good health
C. A measure of dietary health
D. A type of infection

Correct answer: B

Rationale: The correct answer is B: 'Measures contributing to cleanliness and good health.' Hygiene encompasses practices that promote cleanliness and overall good health, such as washing hands, maintaining personal hygiene, and keeping the surroundings clean. Choice A has been revised to 'General cleanliness and good health practices' to better reflect the concept of hygiene. Hygiene goes beyond just cleanliness to include specific measures for maintaining health. Choice C is incorrect as hygiene is not specifically related to dietary health; it is more about cleanliness and health practices. Choice D is incorrect as hygiene is not a type of infection; it is about preventing infections through proper practices.

4. Which phrase correctly completes the sentence? She went to the party ___ her dislike for the host.

A. Despite of
B. Even though
C. Although
D. In spite of

Correct answer: D

Rationale: The correct phrase to complete the sentence is 'In spite of.' This phrase is used to indicate that an action is taken despite a particular circumstance or feeling. In this case, she went to the party in spite of her dislike for the host, meaning she attended the party regardless of her negative feelings towards the host. Choice A, 'Despite of,' is incorrect as the correct phrase is 'Despite,' without the preposition 'of.' Choice B, 'Even though,' is not the best fit in this context as it does not express the contrast between attending the party and disliking the host as effectively as 'In spite of.' Choice C, 'Although,' is also not the most suitable choice as it is used to introduce a contrast, but 'In spite of' provides a stronger emphasis on the contradiction between attending the party and disliking the host.

5. The US __________ most of its silicone chips from Japan and China to stay competitive in the tech market.

A. Deports
B. Exports
C. Reports
D. Imports

Correct answer: D

Rationale: The US imports most of its silicone chips from Japan and China, indicating that the silicone chips are being brought into the US from these countries. 'Imports' refers to the act of bringing goods or services into one country from another, which accurately describes the scenario described in the question. The other choices are incorrect: 'Deports' means expelling individuals from a country, 'Exports' mean sending goods to another country, and 'Reports' mean providing information or data.
