HESI A2
Vocabulary for HESI A2
1. What does Incidence mean?
- A. Occurrence
- B. Disappearance
- C. Growth
- D. Repetition
Correct answer: A
Rationale: The correct answer is A: 'Occurrence.' Incidence refers to the frequency or occurrence of something happening. Choice B, 'Disappearance,' is incorrect as it means vanishing or ceasing to exist. Choice C, 'Growth,' is incorrect as it refers to an increase in size, number, or development. Choice D, 'Repetition,' is incorrect as it means the action of repeating something that has already been said or written.
2. 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.
3. What is another word for AEGIS?
- A. Relationship
- B. Respectability
- C. Ramifications
- D. Responsibility
Correct answer: B
Rationale: AEGIS is synonymous with protection, sponsorship, or support. Respectability aligns with this notion as it relates to being socially acceptable or esteemed, which can be seen as a form of protection or favorable regard. 'Relationship' (Choice A) does not capture the protective or supportive aspect of AEGIS. 'Ramifications' (Choice C) and 'Responsibility' (Choice D) are not synonyms for AEGIS. They do not convey the sense of protection or support associated with it.
4. What is the definition of adverse?
- A. Desirable
- B. Undesired, possibly harmful
- C. Beneficial
- D. Neutral
Correct answer: B
Rationale: The term 'adverse' is used to describe something that is unfavorable, unwanted, or potentially harmful. This makes choice B, 'Undesired, possibly harmful,' the correct definition. Choices A, C, and D are incorrect because they describe positive (desirable, beneficial) or neutral characteristics, which are the opposite of what 'adverse' means.
5. What is the outer bone in the lower leg called?
- A. fascia
- B. fibrous
- C. filial
- D. fibula
Correct answer: D
Rationale: The outer bone in the lower leg is called the fibula, not fascia, fibrous, or filial. The fibula is a slender bone that runs alongside the larger tibia in the lower leg. While it provides stability and support to leg muscles, its main function is not weight-bearing like the tibia. Therefore, the correct answer is the fibula.
