HESI A2

Vocabulary HESI A2 Practice Test

1. What does 'expand' mean?

A. To decrease in size
B. To increase in size or amount
C. To spread out
D. To eliminate

Correct answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

2. Choose the meaning of the word projected in the following sentence: 'Treatment is projected to last three months or more.'

A. Protruded
B. Guaranteed
C. Estimated
D. Alleged

Correct answer: C

Rationale: In this context, 'projected' is used to indicate an estimation or prediction of the duration of the treatment. Therefore, it aligns closest in meaning to 'estimated.' Choice A, 'Protruded,' means to extend beyond or above a surface, which does not fit the context of the sentence. Choice B, 'Guaranteed,' means to provide assurance, which is not the intended meaning in the sentence. Choice D, 'Alleged,' means to claim without proof, which is not the correct interpretation in this context.

3. What is the meaning of Diameter?

A. The width of a structure
B. The distance across the center of an object
C. The height of an object
D. The radius of a circle

Correct answer: B

Rationale: The correct answer is B. Diameter is defined as the distance across the center of an object, typically a circle. Choice A is incorrect because width refers to the measurement of something from side to side, not necessarily through the center. Choice C is incorrect because height is a measurement from top to bottom, not across the center. Choice D is incorrect because the radius of a circle is the distance from the center to any point on the circle's circumference, not the distance across the center.

4. Select the meaning of the underlined word in the following sentence. At this point, we are providing mainly palliative care.

A. Scientific
B. Surgical
C. Soothing
D. Serious

Correct answer: C

Rationale: In the context of the sentence, 'palliative care' refers to care that is focused on providing relief from the symptoms and stress of a serious illness. It is not aimed at curing the illness but rather at providing comfort and improving quality of life. Therefore, the meaning of 'palliative' in this context is to soothe or alleviate suffering, making 'soothing' the correct choice. The other options, 'scientific,' 'surgical,' and 'serious,' do not capture the essence of palliative care, which is centered around providing comfort and relief rather than focusing on scientific or surgical interventions or emphasizing seriousness.

5. 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.
