Vocabulary HESI A2 Practice Test

1. What does the word UBIQUITOUS mean?

A. Widespread
B. Miniscule
C. Invalid
D. Unit

Correct answer: A

Rationale: The word UBIQUITOUS means something that is found everywhere or is very common. Therefore, the correct meaning for ubiquitous is 'widespread'. 'Miniscule' means very small, 'invalid' means not valid or acceptable, and 'unit' refers to a single entity or component, making them incorrect choices in the context of the word ubiquitous.

2. Select the meaning of the underlined word in the following sentence. In children with high fevers, the use of aspirin is contraindicated.

A. Banned
B. Inadvisable
C. Anticipated
D. Expedient

Correct answer: B

Rationale: The word 'contraindicated' means not recommended or inadvisable in this context. It suggests that using aspirin for children with high fevers is not a good idea or is not suitable. The other options (A. Banned, C. Anticipated, D. Expedient) do not accurately convey the meaning of the word 'contraindicated' in this sentence. 'Banned' implies a prohibition, 'Anticipated' means expected, and 'Expedient' means convenient or practical, none of which capture the intended meaning of 'contraindicated.'

3. In medicine, to be resistant is to be ___________.

A. unwilling
B. unaffected by
C. opposed to
D. accepting of

Correct answer: B

Rationale: In medicine, when a microorganism or pathogen is described as resistant, it means that it is not affected by the drug or treatment being used against it. Resistance can develop due to various factors, making the pathogen no longer susceptible to the effects of the treatment. Therefore, the correct answer is 'unaffected by.' The other choices are incorrect: 'unwilling' and 'opposed to' do not accurately describe the concept of resistance in medicine, and 'accepting of' is the opposite of what resistance represents in this context.

4. Which of the following is the plural form of the noun 'stimulus'?

A. Stimulus
B. Stimuli
C. Stimulis
D. Stimula

Correct answer: B

Rationale: The correct answer is 'Stimuli.' When forming the plural of 'stimulus,' the correct form is 'stimuli.' Choice A, 'Stimulus,' is the singular form, not the plural. Choice C, 'Stimulis,' is an incorrect spelling. Choice D, 'Stimula,' is also an incorrect form for the plural of 'stimulus.' Therefore, 'Stimuli' is the only correct plural form.

5. John Kennedy was a senator before he _____ President in 1960.

A. was elected
B. became
C. was made
D. become

Correct answer: A

Rationale: The correct answer is 'was elected.' This choice is the most appropriate as it correctly indicates the action of being chosen through a voting process in the past. In this context, 'was elected' is the right verb form to show that John Kennedy became President in 1960 after winning an election. The other choices are incorrect: 'became' is a simple past verb form that doesn't convey the electoral process, 'was made' implies a passive action rather than an active election, and 'become' is not the correct past tense form needed in this sentence.
