HESI A2 Vocabulary Practice Test

1. What does 'Contract' mean?

A. To expand
B. To draw together
C. To elongate
D. To dissolve

Correct answer: B

Rationale: The correct answer is B: 'To draw together.' Contract means to reduce in size or draw together. Choices A, C, and D are incorrect because they suggest actions opposite to what contracting means. A: 'To expand,' C: 'To elongate,' and D: 'To dissolve' all indicate actions that involve increasing in size or breaking apart, which are the opposite of what contracting means.

2. Which part of the brain is responsible for controlling balance and coordination?

A. Cerebellum
B. Cerebrum
C. Brainstem
D. Medulla oblongata

Correct answer: A

Rationale: The cerebellum is the correct answer. It is responsible for controlling balance, coordination, and fine motor movements. The cerebrum is mainly associated with higher brain functions such as thinking and decision-making, not specifically balance and coordination. The brainstem is responsible for basic life functions like breathing and heartbeat, while the medulla oblongata is involved in regulating autonomic functions like breathing, heart rate, and blood pressure. Therefore, the cerebellum stands out as the key brain region for maintaining physical control and movement.

3. What is the meaning of 'Exemplary'?

A. Disappointing
B. Praiseworthy
C. Ordinary
D. Unacceptable

Correct answer: B

Rationale: The correct answer is B: 'Praiseworthy.' Exemplary is used to describe something that is commendable, outstanding, or worthy of praise. Therefore, the meaning of 'Exemplary' is praiseworthy, not disappointing, ordinary, or unacceptable. Choice A is incorrect because 'Disappointing' is the opposite of 'Exemplary.' Choice C is incorrect as 'Ordinary' does not reflect the exceptional nature of 'Exemplary.' Choice D is incorrect as 'Unacceptable' is the opposite meaning of 'Exemplary.'

4. Throughout this passage, the word suit means?

A. A set of clothing.
B. A group of cards in a deck.
C. A legal case.
D. A formal request.

Correct answer: B

Rationale: The correct answer is B. In the passage, the word 'suit' refers to one of the four groups of cards in a deck of playing cards. The passage explains how the suits of cards, such as spades, hearts, diamonds, and clubs, are used in the game of Bridge. Choice A, 'A set of clothing,' is incorrect as it does not relate to the context of playing cards. Choice C, 'A legal case,' and Choice D, 'A formal request,' are also incorrect as they have no relevance to the discussion of card games in the passage.

5. 72 chromosomes undergo meiosis. How many chromosomes will be in each gamete?

A. 18
B. 36
C. 72
D. 144

Correct answer: A

Rationale: During meiosis, the number of chromosomes is halved in each gamete. Since 72 chromosomes undergo meiosis, each gamete will contain half of that number, which is 36 chromosomes. Therefore, the correct answer is 18 chromosomes in each gamete. Choice B (36 chromosomes) is incorrect because it represents the total number of chromosomes that undergo meiosis, not the number in each gamete. Choice C (72 chromosomes) is incorrect as it represents the initial number of chromosomes, not the number in each gamete after meiosis. Choice D (144 chromosomes) is incorrect as it doubles the initial number of chromosomes, which is not the outcome of meiosis.
