Vocabulary HESI A2 Practice Test

1. The development of the disease was INSIDIOUS.

Correct answer: D

Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.

2. Choose the meaning of the word 'quarantine' in the following sentence: 'The patients are under quarantine until further notice.'

Correct answer: D

Rationale: In this sentence, the word 'quarantine' is used to convey the idea that the patients are isolated or separated from the general population. Quarantine is often implemented to prevent the spread of diseases or infections, and in this context, it implies confinement or isolation to ensure the safety of others. The other choices are incorrect because 'A' refers to specialized medical attention, 'B' refers to a specific medical treatment, and 'C' implies being held against one's will in a rehab facility, none of which capture the meaning of 'quarantine' as used in the sentence provided.

3. What does Lateral mean?

Correct answer: D

Rationale: The correct answer is D: 'On the side.' Lateral means situated on the side or away from the midline. Choices A, B, and C are incorrect because lateral specifically refers to a position that is situated away from the midline, not near it, at the top of the body, or on the side.

4. Which phrase should be moved to improve sentence clarity? 'He opened the door slowly, trying not to wake the baby.'

Correct answer: A

Rationale: Placing 'trying not to wake the baby' at the beginning as in option A clarifies the purpose of the action right away, improving the sentence's flow.

5. What does 'External' refer to?

Correct answer: B

Rationale: The term 'External' refers to something that is located outside the body. In this context, it specifically denotes a position or location that is beyond the confines of the body's boundaries. Choice A is incorrect as 'External' means outside, not inside. Choice C is incorrect as it confuses the internal exposure with external positioning. Choice D is incorrect as 'External' does not necessarily mean near the skin, but rather outside the body.
