Quizlet Vocabulary HESI A2

1. What does Depth mean?

A. The thickness of an object
B. Downward measurement from a surface
C. The length of a surface
D. The area between two points

Correct answer: B

Rationale: Depth refers to the distance or downward measurement from a surface. It is not the thickness of an object (Choice A), as thickness is the measure of how thick or thin an object is, not necessarily related to depth. Additionally, it is not the length of a surface (Choice C) because length typically refers to the longest dimension of an object rather than its depth. Finally, it is not the area between two points (Choice D) because area is a measure of the space within a boundary defined by points, while depth specifically refers to the vertical distance below a surface.

2. What does Exposure mean?

A. Protection from external elements
B. Contact
C. Absorption
D. Isolation

Correct answer: B

Rationale: Exposure refers to coming into contact with external elements. Choice A is incorrect as exposure does not imply protection but rather contact. Choice C, absorption, refers to the process of soaking up or taking in something. Choice D, isolation, means being separated or kept apart from others, which is not synonymous with exposure.

3. What does Milieu mean?

A. A person's background
B. The environmental condition or setting
C. A person's history
D. The chemical composition

Correct answer: B

Rationale: The correct answer is B: 'The environmental condition or setting.' Milieu refers to the surroundings or environment in which a person lives or operates. Choice A ('A person's background') is incorrect as it refers more to someone's personal history rather than the external environment. Choice C ('A person's history') is also incorrect as it specifically relates to an individual's past events and experiences. Choice D ('The chemical composition') is unrelated to the meaning of milieu, which pertains to the physical or social setting.

4. What is another word for ADHERE?

A. Remain intact
B. Loosen
C. Hold fast
D. Position next to

Correct answer: C

Rationale: The correct answer is 'C: Hold fast.' ADHERE means to stay firmly attached or stick to something. 'Remain intact' (A) implies staying whole or undamaged, 'Loosen' (B) means to make less tight or firm, and 'Position next to' (D) refers to being placed adjacent to something, which do not accurately capture the meaning of ADHERE.

5. The abbreviation DTs on a patient’s chart stands for ___________.

A. deep tendon reflex
B. descending thorax
C. delirium tremens
D. dextrose in water

Correct answer: C

Rationale: The abbreviation DTs on a patient's chart stands for delirium tremens, which is a severe form of alcohol withdrawal. Symptoms of delirium tremens include confusion, hallucinations, severe agitation, seizures, and autonomic instability. This condition requires prompt medical treatment to prevent serious complications. Choices A, B, and D are incorrect. Deep tendon reflex (A) refers to the reflex response elicited by tapping a tendon with a reflex hammer, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for various medical purposes but is not represented by the abbreviation DTs.
