HESI A2 Practice Vocabulary
1. What does 'Parameter' mean?
- A. A constant variable
- B. A characteristic or constant factor
- C. A measurable limit
- D. A calculated risk
Correct answer: B
Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.
2. Choose the meaning of the word 'exposure' in the following sentence: 'People with weakened immune systems should avoid exposure to flu.'
- A. Disclosure
- B. Pretense
- C. Contact
- D. Display
Correct answer: C
Rationale: In this sentence, the word 'exposure' is used to refer to coming in contact with the flu virus. Therefore, in this context, the meaning of 'exposure' is related to 'contact.' Choices A, B, and D are incorrect. 'Disclosure' means revealing information, 'pretense' means pretending, and 'display' means to show or exhibit, none of which captures the intended meaning of 'exposure' in the sentence provided.
3. Medicine that is given in inhalant form is ___________.
- A. dissolved
- B. injected
- C. taken orally
- D. breathed in
Correct answer: D
Rationale: Medicine that is given in inhalant form is intended to be breathed in, typically through the mouth or nose. This allows the medication to reach the lungs directly and be absorbed into the bloodstream quickly. Examples of medications given in inhalant form include inhalers used for conditions like asthma and nebulizers for respiratory treatments. Choices A, B, and C are incorrect because medicine in inhalant form is not dissolved, injected, or taken orally; instead, it is inhaled to reach the lungs.
4. What does it mean if a patient is lethargic?
- A. Active
- B. Exhausted
- C. Confused
- D. Restless
Correct answer: B
Rationale: Lethargic means feeling exhausted or sluggish. Being lethargic is the opposite of being active (choice A), confused (choice C), or restless (choice D). When a patient is lethargic, they lack energy and may appear tired or sluggish.
5. Another word for UNDER OBSERVATION is?
- A. Cognition
- B. Isolation
- C. Surveillance
- D. Assessment
Correct answer: C
Rationale: Another word for UNDER OBSERVATION is surveillance. Surveillance refers to the close observation of a person, group, or place, especially in a secret or discreet manner. It involves monitoring and watching over someone or something closely for a specific purpose. Therefore, the word 'surveillance' is the most suitable synonym for under observation in this context. Choice A, 'Cognition,' refers to the mental process of acquiring knowledge and understanding through thoughts, experience, and the senses; it is not synonymous with under observation. Choice B, 'Isolation,' means the process or fact of isolating or being isolated, which does not convey the idea of close monitoring. Choice D, 'Assessment,' involves evaluating or judging the nature, ability, or quality of something, which is different from the act of observing closely.
