HESI A2

Vocabulary for HESI A2

1. What does the word BILATERAL mean?

A. 2-sided
B. Straight
C. Symmetrical
D. On one side

Correct answer: A

Rationale: The word 'bilateral' means having or relating to two sides. It is often used to describe something that occurs on both sides, such as bilateral symmetry in which an object is symmetrical on two sides. Choice B, 'Straight,' does not capture the meaning of bilateral. Choice C, 'Symmetrical,' while related, does not specifically convey the idea of something pertaining to two sides. Choice D, 'On one side,' is the opposite of what bilateral means.

2. An inability to be lucid in the early morning means the person is unable to behave in which way?

A. Coherent
B. Speculative
C. Furtive
D. Animated

Correct answer: A

Rationale: An inability to be lucid in the early morning means the person is unable to behave in a coherent way. Lucidity refers to clarity of thought and coherence in one's behavior or speech. If someone is not lucid, they may be confused, disoriented, or unable to express themselves clearly. Therefore, the correct choice is A. Coherent. Choices B, C, and D are incorrect because being unable to be lucid does not necessarily mean the person is behaving in a speculative, furtive, or animated way.

3. Identify the incomplete sentence.

A. While they were sleeping.
B. The dog slept.
C. The sun rises in the east.
D. They went home.

Correct answer: A

Rationale: The correct answer is A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.

4. What is the process of digestion?

A. Production of enzymes
B. The mechanical and chemical breakdown of food
C. Absorption of nutrients in the blood
D. Movement of enzymes

Correct answer: B

Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.

5. Which sentence correctly uses the word 'affect'?

A. The medication had no effect on the patient's symptoms
B. The noise did not affect his sleep
C. The bright light will affect your eyes
D. The cold weather did not affect her mood

Correct answer: B

Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.
