Vocabulary for HESI A2
1. This medication works by inhibiting the action of a certain enzyme. What does inhibiting mean?
- A. Blocking
- B. Hindering
- C. Energizing
- D. Blocking improvement
Correct answer: B
Rationale: The correct answer is 'B: Hindering.' Inhibiting means to hinder or slow down a process. Choices A and D are similar and imply a complete stop of the process rather than just slowing it down. Choice C, 'Energizing,' is the opposite of inhibiting, as it means to provide energy or stimulate rather than hinder.
2. What does it mean if something is distended?
- A. Shrunken
- B. Swollen
- C. Narrow
- D. Flattened
Correct answer: B
Rationale: When something is described as distended, it means that it is swollen or expanded, not shrunken, narrow, or flattened. In a medical context, distention often refers to an abnormal swelling or enlargement of an organ or structure. 'Shrunken' is incorrect as it means reduced in size, 'narrow' is incorrect as it means not wide, and 'flattened' is incorrect as it means pressed or squeezed flat.
3. Which word is NOT USED CORRECTLY? It sure isn't going to rain during the next playoff.
- A. Ain't
- B. During
- C. Sure
- D. Playoff
Correct answer: A
Rationale: The correct answer is A. 'Ain't' is not grammatically correct in formal writing or speech; it should be 'isn't.' 'Ain't' is considered slang and is not appropriate for formal contexts. The other choices ('During,' 'Sure,' 'Playoff') are used correctly in the sentence.
4. He tried to remember the names of all the people who were there that night.
- A. Whom
- B. That
- C. Which
- D. Whose
Correct answer: B
Rationale: The word 'that' is the correct relative pronoun to use in this context to refer to the people who were present that night. 'Whom' is used for objects of a verb or preposition, 'which' is used for things, and 'whose' is a possessive pronoun.
5. When people masticate, what do they use?
- A. Fingers
- B. Eyes and ears
- C. Gums and teeth
- D. Heels and toes
Correct answer: C
Rationale: When people masticate, they use their gums and teeth to chew and physically break down food into smaller pieces for easier digestion. The process of mastication is essential for proper digestion in the human body. Choices A, B, and D are incorrect as fingers, eyes, ears, heels, and toes are not involved in the process of chewing or mastication.
