HESI A2 Vocabulary Practice Test
1. The eye drops were intended to _____ the pupils for the eye exam.
- A. dilate
- B. constrict
- C. enlarge
- D. decrease
Correct answer: A
Rationale: The correct answer is 'dilate.' Eye drops are used to dilate the pupils, meaning to widen or enlarge them, which is necessary for an eye exam to allow more light to enter the eye. 'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.
2. She was so mad at her boyfriend, she _____ on him when he called.
- A. hung up
- B. picked
- C. held
- D. held on
Correct answer: A
Rationale: The correct answer is 'A: hung up.' In this context, 'hung up' is the correct phrasal verb to indicate ending a phone call abruptly. The phrase 'hung up' means to abruptly end a phone call. The other choices do not fit the context. 'Picked' implies selecting something, 'held' means to grasp or support something, and 'held on' implies maintaining a grip or connection rather than ending the call.
3. If a patient's condition is deteriorating, he is ______.
- A. Improving
- B. Getting worse
- C. Stabilizing
- D. Reversing
Correct answer: B
Rationale: The correct answer is 'B: Getting worse.' When a patient's condition is deteriorating, it means that their health is declining or worsening. Choices A, C, and D are incorrect because improving, stabilizing, and reversing all indicate positive changes or holding steady, which are the opposite of deteriorating.
4. What does Endogenous mean?
- A. Produced outside the body
- B. Produced within the body
- C. Taken from an external source
- D. Linked to environmental factors
Correct answer: B
Rationale: The correct answer is B: 'Produced within the body.' Endogenous refers to substances or processes that originate or are produced within an organism or system. Choices A, C, and D are incorrect. Choice A, 'Produced outside the body,' is the opposite of endogenous. Choice C, 'Taken from an external source,' describes exogenous rather than endogenous. Choice D, 'Linked to environmental factors,' is not a direct definition of endogenous.
5. What does Ominous mean?
- A. Insignificant
- B. Significantly important and dangerous
- C. Trivial
- D. Harmless
Correct answer: B
Rationale: Ominous means giving the impression that something bad or unpleasant is going to happen; threatening; inauspicious. This choice is correct as it accurately reflects the meaning of the term 'Ominous.' Choices A, C, and D are incorrect because they all suggest a lack of importance, danger, or threat, which is opposite to the actual meaning of 'Ominous.'
