HESI A2 Practice Vocabulary
1. What does Dilute mean?
- A. To concentrate
- B. To make a liquid less concentrated
- C. To solidify
- D. To evaporate
Correct answer: B
Rationale: The correct definition of dilute is to make a liquid less concentrated. When a substance is diluted, it means it has been mixed with another substance to reduce its strength or concentration. Option A, 'To concentrate,' is the opposite of dilute. Option C, 'To solidify,' means to make or become hard or solid, which is unrelated to diluting a liquid. Option D, 'To evaporate,' means to change from a liquid to a vapor, also unrelated to diluting a liquid. Therefore, the correct answer is B.
2. What does the term 'bilingual' mean in the sentence: 'Being bilingual is an advantage for a nurse'?
- A. Able to speak more than one language
- B. Able to use either hand
- C. Not squeamish about blood
- D. Can remember everything
Correct answer: A
Rationale: The correct answer is A: 'Able to speak more than one language.' In the context provided, 'bilingual' refers to the ability to speak two languages. This is advantageous for a nurse who may need to communicate with patients from diverse linguistic backgrounds. Choices B, C, and D are incorrect because they do not align with the meaning of 'bilingual' as the ability to speak multiple languages.
3. What does 'Deficit' mean?
- A. An excess of something
- B. A deficiency or lack of something
- C. An abundance of something
- D. A stable amount
Correct answer: B
Rationale: The correct answer is B: 'A deficiency or lack of something.' The term 'deficit' refers to a shortage or inadequacy of something. Choice A is incorrect because a surplus means an excess, which is the opposite of a deficit. Choice C is incorrect as an abundance signifies a large quantity or more than enough of something. Choice D is incorrect as a stable amount does not convey the concept of a deficit.
4. Identify the sentence with a misplaced modifier.
- A. The child found a dollar walking to school
- B. Walking to school, the child found a dollar
- C. The teacher found a note after class
- D. After class, the teacher found a note
Correct answer: A
Rationale: The correct answer is A because the phrase 'walking to school' seems to modify 'a dollar,' which is illogical. The intended meaning is that the child found the dollar while walking to school. In sentence B, the modifier is correctly placed at the beginning of the sentence, indicating that the child found the dollar while walking to school. Choices C and D do not contain any misplaced modifiers.
5. Which sentence correctly uses the word 'affect'?
- A. The medication had no effect on the patient's symptoms
- B. The noise did not affect his sleep
- C. The bright light will affect your eyes
- D. The cold weather did not affect her mood
Correct answer: B
Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.
