Quizlet Vocabulary HESI A2

1. What does 'Excess' mean?

A. Less than what is needed or usual
B. More than what is needed or usual
C. Equal to the amount needed
D. Below average

Correct answer: B

Rationale: The correct answer is B: 'More than what is needed or usual.' Excess refers to an amount that surpasses what is required or typical. Choice A is incorrect because 'less than what is needed or usual' is the opposite of excess. Choice C is incorrect as 'equal to the amount needed' does not imply excess. Choice D is incorrect as 'below average' does not capture the essence of excess.

2. 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.

3. Which phrase correctly completes the sentence? 'As we celebrated the start of the evening festivities, our glasses ___ and a toast was made by our host.'

A. Were risen
B. Were rose
C. Were raised
D. Arose

Correct answer: C

Rationale: The correct answer is 'Were raised.' This phrase is the correct passive form, indicating the action of lifting the glasses during the toast. Choices A, B, and D are incorrect because 'were risen' is not grammatically correct, 'were rose' is not the appropriate verb form, and 'arose' does not convey the action of lifting the glasses as required in the sentence.

4. When a body part has atrophied, it has ____?

A. Enlarged
B. Withered
C. Swollen
D. Damaged

Correct answer: B

Rationale: The correct answer is B: 'Withered.' When a body part atrophies, it shrinks or wastes away. This term is associated with a decrease in muscle mass or tissue due to various reasons like lack of use or injury. Choices A, C, and D are incorrect because atrophy does not refer to enlargement, swelling, or damage, but rather to wasting away or shrinking.

5. What is the best description for the abbreviation CDC?

A. An online social network
B. A test for postgraduate students
C. A well-known pharmaceutical
D. A public health association

Correct answer: D

Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.
