Vocabulary for HESI A2
1. What does Constrict mean?
- A. To expand
- B. To draw together
- C. To freeze
- D. To dissolve
Correct answer: B
Rationale: The correct answer is B: 'To draw together.' Constrict means to narrow or squeeze, making something smaller or tighter. This is the opposite of expanding (choice A), freezing (choice C), and dissolving (choice D), which do not involve the action of drawing together or becoming smaller.
2. Identify the correct sentence structure.
- A. The cat sleeping on the mat
- B. The cat is sleeping on the mat
- C. The mat that the cat is sleeping on
- D. Sleeping on the mat is the cat
Correct answer: B
Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.
3. What is a diagnostic test?
- A. One that locates a cure
- B. One that looks for a cause
- C. One that examines the skin
- D. One that is performed on doctors
Correct answer: B
Rationale: A diagnostic test is a medical test or procedure performed to identify the cause of a health problem, disease, or condition. It helps healthcare providers make accurate diagnoses and determine appropriate treatments for patients. Choice A is incorrect because a diagnostic test does not locate a cure but rather aims to identify the cause of a health issue. Choice C is incorrect as a diagnostic test is not specifically for examining the skin but can involve various types of tests on different parts of the body. Choice D is incorrect as a diagnostic test is not performed on doctors but on patients to diagnose their health conditions.
4. 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.
5. To critique something is to ___________.
- A. appraise it
- B. condemn it
- C. extol it
- D. berate it
Correct answer: B
Rationale: To critique something means to evaluate and judge it, often pointing out its faults or shortcomings. Condemning something implies expressing strong disapproval or criticism of it, which aligns closely with the concept of critiquing. 'Appraise' means to assess the value or quality of something, which is not necessarily negative. 'Extol' means to praise highly, which is the opposite of critiquing. 'Berate' means to scold or criticize someone angrily, which is not the same as objectively evaluating something as in critiquing. Therefore, 'condemn it' is the most suitable choice among the given options.
