Vocabulary HESI A2 Practice Test

1. What does Labile mean?

A. Stable
B. Changing rapidly and often
C. Unchanging
D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

2. What is the definition of the word ENVIRONMENT?

A. the major ideas of the quality of life
B. the assistance found outside the family
C. the elements inside and outside of a person
D. the positive and negative aspects of a home

Correct answer: C

Rationale: The word 'environment' refers to the surroundings or conditions in which a person, animal, or plant lives or operates. It encompasses the elements both inside and outside of an individual, including physical, biological, social, and cultural factors. Option C, which mentions the elements inside and outside of a person, is the most accurate description of the word 'environment.' Choices A, B, and D do not capture the comprehensive nature of the term 'environment' and are therefore incorrect.

3. The voice box may be called the ______

A. Pharynx
B. Larynx
C. Trachea
D. Esophagus

Correct answer: B

Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.

4. The patient made a ritualistic arranging of the food on his plate. Which word best describes the patient's repetitive behavior?

A. Formal
B. Ritualistic
C. Formalizing
D. Ritual

Correct answer: B

Rationale: The correct answer is 'Ritualistic.' This adjective describes actions performed in a habitual or ceremonial manner, which aligns with the context of the patient's repeated arrangement of food. 'Formal' (choice A) does not capture the repetitive nature of the behavior. 'Formalizing' (choice C) refers to the process of making something formal rather than describing repetitive behavior. 'Ritual' (choice D) is a noun and does not best describe the patient's behavior in this context.

5. Select the meaning of the following phrase. 'A system of procedures to follow.'

A. Regimen
B. Regime
C. Testament
D. Treatment

Correct answer: A

Rationale: The correct answer is 'Regimen.' 'Regimen' refers to a prescribed set of procedures or a routine, especially related to health. Choice B, 'Regime,' typically refers to a system of government or a ruling period. Choice C, 'Testament,' means a person's will or a statement of belief. Choice D, 'Treatment,' is a medical care given to a patient.
