HESI A2 Practice Test Vocabulary
1. What is the term for the word part placed before a word to change its meaning?
- A. Prefix
- B. Affix
- C. Suffix
- D. Vocab
Correct answer: A
Rationale: The correct answer is 'Prefix.' A prefix is a word part that is placed before a root word to modify its meaning. In this case, a prefix changes the meaning of the root word. Choice B, 'Affix,' is a broader term that includes prefixes, suffixes, and infixes. Choice C, 'Suffix,' is a word part placed after a root word to modify its meaning, not before. Choice D, 'Vocab,' is unrelated to the word part placed before a word.
2. What is the best description of the word 'suppress'?
- A. stop
- B. push up
- C. release
- D. strain
Correct answer: A
Rationale: The correct answer is A: 'stop.' 'Suppress' means to stop or hold back something. Choice B, 'push up,' is incorrect as it does not accurately reflect the meaning of 'suppress.' Choice C, 'release,' is incorrect as it is the opposite of 'suppress.' Choice D, 'strain,' is also incorrect as it does not capture the meaning of 'suppress.'
3. Select the word that means 'a violent seizure.'
- A. revelation
- B. nutrient
- C. contraption
- D. paroxysm
Correct answer: D
Rationale: 'Paroxysm' is the correct answer as it refers to a sudden, violent seizure or outburst. The other choices are incorrect because 'revelation' means a surprising and previously unknown fact, 'nutrient' refers to a substance that provides nourishment, and 'contraption' means a machine or device that is strange or unnecessarily complicated.
4. What does the term 'residual' refer to in the following sentence? The nurse was asked to record the residual urine in the patient's bladder.
- A. Measurement
- B. What is left
- C. Total volume
- D. Color and clarity
Correct answer: B
Rationale: The term 'residual' refers to what is left after the main part has been taken or used. In this context, 'residual urine' specifically means the urine that remains in the bladder after urination. Choices A, C, and D do not accurately capture the meaning of 'residual' in this sentence. 'Measurement' (A) is too general, 'Total volume' (C) does not specifically pertain to what remains, and 'Color and clarity' (D) is unrelated to the concept of what is left.
5. Select the meaning of the word 'undulate' in the sentence: 'Each shiver made his muscles undulate beneath his skin.'
- A. Ripple
- B. Shake
- C. Flatten
- D. Unknot
Correct answer: A
Rationale: In this context, 'undulate' means to move in a smooth, wave-like motion. An undulation of muscles is a subtle, continuous rippling or rolling movement, making 'ripple' the most appropriate synonym in this sentence. 'Shake' (Choice B) is incorrect as it implies a more abrupt and irregular movement. 'Flatten' (Choice C) and 'Unknot' (Choice D) are unrelated to the smooth, wave-like motion described in the sentence.
