Quizlet Vocabulary HESI A2
1. The ETIOLOGY of the flu epidemic of 1918 remains unknown to this day.
- A. Pathology
- B. Transmission
- C. Etiology
- D. Mortality rate
Correct answer: C
Rationale: The term 'etiology' refers to the cause or origins of a disease. In this context, the question is asking for the underlying reason or cause of the flu epidemic of 1918. Therefore, the correct answer is C. 'Etiology.' Choice A, 'Pathology,' is incorrect as it refers to the study of diseases rather than the cause itself. Choice B, 'Transmission,' is incorrect as it relates to how a disease spreads rather than its cause. Choice D, 'Mortality rate,' is incorrect as it refers to the number of deaths caused by a disease rather than the cause of the disease itself.
2. Choose the meaning of the word 'mercurial' in the following sentence: 'Due to his mercurial temperament, Justin did not work well with others.'
- A. Continuous
- B. Unpredictable
- C. Mercenary
- D. Miraculous
Correct answer: B
Rationale: The word 'mercurial' in this sentence means unpredictable or prone to sudden changes in mood or behavior. Justin's temperament can be characterized as unpredictable, which is causing him to not work well with others. Choice A, 'Continuous,' does not align with the meaning of 'mercurial' as it implies a steady, uninterrupted flow. Choice C, 'Mercenary,' refers to being primarily motivated by money or reward, which is not the context here. Choice D, 'Miraculous,' means extraordinary or remarkable, which is not the intended meaning in this sentence.
3. Which word means to suggest, to hint, to express indirectly?
- A. Imply
- B. Infer
- C. Opinion
- D. Latter
Correct answer: A
Rationale: 'Imply' means to suggest or indicate something indirectly. In this context, 'Infer' (choice B) is incorrect as it means to deduce or conclude information based on evidence and reasoning, not to suggest. 'Opinion' (choice C) refers to a personal view or judgment, not the act of suggesting indirectly. 'Latter' (choice D) means the second of two things mentioned.
4. What does Endogenous mean?
- A. Produced outside the body
- B. Produced within the body
- C. Taken from an external source
- D. Linked to environmental factors
Correct answer: B
Rationale: The correct answer is B: 'Produced within the body.' Endogenous refers to substances or processes that originate or are produced within an organism or system. Choices A, C, and D are incorrect. Choice A, 'Produced outside the body,' is the opposite of endogenous. Choice C, 'Taken from an external source,' describes exogenous rather than endogenous. Choice D, 'Linked to environmental factors,' is not a direct definition of endogenous.
5. Select the meaning of the word 'reflex' in the sentence: 'The typical patellar reflex takes only 50 milliseconds between the initial tap and the leg extension.'
- A. Replication
- B. Convulsion
- C. Reaction
- D. Stretching
Correct answer: C
Rationale: In the context of the sentence, the word 'reflex' indicates a quick, automatic response by the body to a stimulus. The patellar reflex, also known as the knee-jerk reflex, involves the leg extending in response to a tap on the patellar tendon. Therefore, the word 'reaction' aligns closely with the nature of the patellar reflex in terms of a rapid and involuntary response. Choices A, B, and D are incorrect: 'Replication' does not capture the concept of a bodily response, 'convulsion' implies a sudden and uncontrollable movement which is not specific to the nature of the patellar reflex, and 'stretching' does not encompass the automatic and rapid nature of a reflex action.
