Vocabulary HESI A2 Practice Test

1. If a nurse is CIRCUMSPECT with patient records, what is she doing?

A. Acting carelessly
B. Guarded
C. Reckless
D. Neglecting

Correct answer: B

Rationale: The correct answer is B: 'Guarded.' Circumspect means to be cautious or guarded. In this context, being circumspect with patient records implies being careful and cautious in handling them, maintaining confidentiality and privacy. Choices A, C, and D are incorrect because circumspect does not mean acting carelessly, reckless, or neglecting; instead, it suggests being watchful and discreet.

2. Which part of the brain is responsible for regulating breathing and heart rate?

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

Correct answer: B

Rationale: The correct answer is the Medulla oblongata. This structure, located in the brainstem, plays a crucial role in regulating essential functions such as breathing, heart rate, and blood pressure. It serves as a control center for autonomic functions necessary for maintaining life. The Cerebrum (Choice A) is mainly responsible for higher brain functions such as thinking and voluntary movements, not for regulating basic physiological processes like breathing and heart rate. The Cerebellum (Choice C) is involved in coordination, balance, and muscle control, but not in regulating breathing and heart rate. The Hypothalamus (Choice D) plays a role in regulating body temperature, hunger, and thirst, but it is not primarily responsible for controlling breathing and heart rate.

3. What is the function of amylase?

A. Breaking down starch
B. Digesting fat
C. Breaking down protein
D. Absorbing water

Correct answer: A

Rationale: The correct answer is A: Breaking down starch. Amylase is an enzyme that specifically functions to break down starch into smaller sugar molecules such as maltose and glucose. This process is essential for the digestion and absorption of carbohydrates in the body. Choices B, C, and D are incorrect because amylase does not digest fat, break down protein, or absorb water; its primary function lies in starch digestion.

4. What action describes what a cat, who is clearly scared of a Rottweiler, will do when the dog enters the room?

A. Cower
B. Engender
C. Enhance
D. Replicate

Correct answer: A

Rationale: When a cat cowers, it means the cat is crouching down or trying to make itself look smaller in fear or apprehension of something, in this case, the Rottweiler. Hence, the word 'cower' accurately describes what the cat would do when faced with a Rottweiler entering the room. The other choices are incorrect: 'Engender' means to cause or give rise to, 'Enhance' means to improve or increase the quality or value of something, and 'Replicate' means to duplicate or reproduce something.

5. Which word correctly completes the sentence? 'The men and women of the graduating class ___ their caps in the air.'

A. Thorough
B. Through
C. Threw
D. Throwing

Correct answer: C

Rationale: The correct answer is 'C: Threw.' In this sentence, we need the past tense form of the verb 'throw' to show the action that occurred. Therefore, 'threw' is the correct choice. 'Thorough' (choice A) means complete or exhaustive, which doesn't fit the context of the sentence. 'Through' (choice B) is a preposition or an adverb, not the correct verb form. 'Throwing' (choice D) is the present participle form and does not match the past tense needed in the sentence.
