HESI A2 Vocabulary 2023
1. 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.
2. Another word for the gonads might be the ___________.
- A. sperm
- B. vagina
- C. testes
- D. pelvis
Correct answer: C
Rationale: Another word for the gonads would be the testes in males and ovaries in females. The gonads are the primary reproductive organs that produce gametes (sperm in males and eggs in females) and sex hormones. The term 'testes' specifically refers to the male gonads, while 'ovaries' would refer to the female gonads. Therefore, 'testes' is the correct answer as it directly relates to the male gonads, making choices A, B, and D incorrect.
3. What is another word for EXPEDITE?
- A. Transfer
- B. Rush
- C. Cancel

'Transfer' (choice A) means to move from one place to another, 'Cancel' (choice C) means to call off, and 'Hold' (choice D) means to keep or detain. Therefore, 'Rush' is the most appropriate synonym for expedite in this context.

Rationale: The correct answer is C: 'Gradual.' In the context provided, 'insidious' describes a disease that develops slowly and harmfully over time, without being easily noticed. Choices A, B, and D are incorrect. 'Sudden' (choice A) means something happening quickly or unexpectedly, 'Suffer' (choice B) means to experience pain or hardship, and 'Graduate' (choice D) means to successfully complete a process or course of study, none of which capture the intended meaning of 'insidious' in this context.
