HESI A2 Vocabulary Practice Test
1. Choose the meaning of the word 'distended' in the following sentence: 'The patient's distended veins were a cause for worry.'
- A. Bleeding
- B. Enlarged
- C. Pressure
- D. Minuscule
Correct answer: B
Rationale: The term 'distended' means swollen or enlarged. In this context, when the patient's veins are described as distended, it implies that they are expanded or swollen beyond their normal size, which can be a cause for worry due to potential health implications. Choice A ('Bleeding') is incorrect as 'distended' does not refer to bleeding but rather to being swollen. Choice C ('Pressure') is incorrect as 'distended' does not directly imply pressure but rather enlargement. Choice D ('Minuscule') is incorrect as 'distended' means the opposite of minuscule, indicating something enlarged or swollen.
2. What is a mass of tissue formed in the ovary known as?
- A. corpus delicti
- B. corpus luteum
- C. corpus striatum
- D. corpus callosum
Correct answer: B
Rationale: A mass of tissue formed in the ovary is known as the corpus luteum. The corpus luteum is a temporary endocrine structure involved in the production of progesterone, which is essential for preparing and maintaining the uterus for pregnancy. Choices A, C, and D are incorrect. Corpus delicti refers to the body of a crime, corpus striatum is a part of the brain, and corpus callosum is a structure that connects the two hemispheres of the brain.
3. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'
- A. Add water to
- B. Reduce by half
- C. Warm up
- D. Decontaminate
Correct answer: A
Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.
4. After robbing the bank, _____.
- A. the thief fled
- B. he escaped
- C. they hid
- D. they fled
Correct answer: A
Rationale: After robbing the bank, 'the thief fled' is the correct choice as it logically follows the action of robbing a bank. The singular pronoun 'he' in choice B is not appropriate as 'the thief' is singular. Choices C and D use 'they,' which is a plural pronoun and does not agree with 'the thief,' making them grammatically incorrect.
5. Select the meaning of the underlined word in the following sentence. The night nursing staff is accountable for those records.
- A. Receptive
- B. Notorious
- C. Responsible
- D. Preoccupied with
Correct answer: C
Rationale: In this context, the word 'accountable' means responsible. The night nursing staff is responsible for those records, meaning they are the ones who are answerable and expected to ensure proper care and maintenance of the records. Choice A, 'Receptive,' does not fit the context as it means willing to listen or accept information. Choice B, 'Notorious,' means famous or well-known, usually for something negative, which is not the intended meaning here. Choice D, 'Preoccupied with,' means to be engrossed or absorbed in something, which does not convey the meaning of being responsible as intended in the sentence.
