HESI A2 Practice Test Vocabulary

1. What is the term for the word part placed before a word to change its meaning?

A. Prefix
B. Affix
C. Suffix
D. Vocab

Correct answer: A

Rationale: The correct answer is 'Prefix.' A prefix is a word part that is placed before a root word to modify its meaning. In this case, a prefix changes the meaning of the root word. Choice B, 'Affix,' is a broader term that includes prefixes, suffixes, and infixes. Choice C, 'Suffix,' is a word part placed after a root word to modify its meaning, not before. Choice D, 'Vocab,' is unrelated to the word part placed before a word.

2. What is another word for toxin?

A. Impurity
B. Element
C. Remedy
D. Poison

Correct answer: D

Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.

3. What is another word for deluge?

A. Earthquake
B. Dimness
C. Downpour
D. Chasm

Correct answer: C

Rationale: A "deluge" is a sudden and heavy rainfall or flood, so the word that is most closely related in meaning to "deluge" is "downpour," which also refers to a heavy and sustained rainfall. The other choices, "earthquake," "dimness," and "chasm," do not relate to a flooding or heavy rainfall situation.

4. A tuberculin skin test should be read within 24 hours of administration.

A. of
B. before
C. after
D. during

Correct answer: A

Rationale: The correct preposition to use after 'within 24 hours' in this context is 'of.' Therefore, the tuberculin skin test should be read within 24 hours of administration. The other choices ('before,' 'after,' 'during') do not correctly convey the relationship between the timing of reading the test and the administration.

5. The car that he had seen at the Ford dealer was the one that he finally decided to _____.

A. buy
B. rent
C. lease
D. sell

Correct answer: A

Rationale: The correct answer is 'buy' because it is the appropriate verb for purchasing a car. In this context, the person saw a car at the Ford dealer and decided to buy it, indicating ownership. Choices B, C, and D are incorrect because 'rent,' 'lease,' and 'sell' do not fit the context of deciding to acquire a car for ownership. Renting and leasing involve temporary possession, while selling involves transferring ownership to another party.
