HESI A2 Vocabulary Quiz

1. What is a diagnostic test?

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.

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.'

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. Which part of the sentence contains a typographical error?

Correct answer: D

Rationale: The correct answer is D. The phrase 'Went form' contains a typographical error. It should be 'went from' to indicate the change in condition correctly. Choice A 'To a,' choice B 'Very strong,' and choice C 'Being' are grammatically correct and do not contain any typographical errors in the given sentence.

4. What does contrite mean?

Correct answer: B

Rationale: The correct answer is B: 'Regretful.' Contrite means feeling regret or remorse. Choice A, 'Guilty,' does not fully capture the meaning of contrite as it implies a judgement of culpability rather than a feeling of remorse. Choice C, 'Shameful,' is incorrect as it focuses on the emotion of shame rather than regret. Choice D, 'Pleased,' is the opposite of what contrite means, as it signifies satisfaction or happiness, which is contradictory to feeling regretful or remorseful.

5. Which sentence uses the word 'present' as an adjective?

Correct answer: B

Rationale: The sentence 'She was present at the meeting' uses 'present' as an adjective. In this context, 'present' describes her state of being at the meeting. The other choices use 'present' as a verb (to give), a noun (a gift), and a verb (to show), making them incorrect in the context of looking for the adjective use of 'present'.
