HESI A2 Practice Test Vocabulary

1. Which sentence uses 'etc.' grammatically correct?

A. The list included diseases such as flu, measles, etc.
B. The list included flu, measles, etc., and other items.
C. The list included flu, measles, etc., diseases, and other items.
D. The list included, flu, etc., measles, diseases, and other items.

Correct answer: A

Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.

2. The rain will CEASE at sundown.

A. Decrease
B. Begin
C. Stop
D. Increase

Correct answer: C

Rationale: The word 'cease' means to stop or come to an end. In the given sentence, it is implied that the rain will stop at sundown, not decrease, begin, or increase. Therefore, the correct option is 'Stop.' 'Decrease' means to become smaller or less, which doesn't fit the context. 'Begin' means to start, which is the opposite of what is stated. 'Increase' means to become or make greater in amount, which is also contrary to the statement.

3. Identify the incomplete sentence.

A. While they were sleeping.
B. The dog slept.
C. The sun rises in the east.
D. They went home.

Correct answer: A

Rationale: The correct answer is A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.

4. Another word for ASSURED is?

A. Confirmed the truth of
B. Sympathized with
C. Denied the truth of
D. Made known to

Correct answer: A

Rationale: The word 'assured' means to have made certain or confident of something. 'Confirmed' is a synonym that aligns with this meaning. Therefore, the correct answer is A, 'Confirmed the truth of.' Choice B, 'Sympathized with,' does not have a similar meaning to 'assured.' Choice C, 'Denied the truth of,' is the opposite in meaning to 'assured.' Choice D, 'Made known to,' does not convey the same sense of certainty as 'assured.'

5. What is the best description for the abbreviation CDC?

A. An online social network
B. A test for postgraduate students
C. A well-known pharmaceutical
D. A public health association

Correct answer: D

Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.
