Vocabulary HESI A2 Practice Test
1. The development of the disease was INSIDIOUS.
- A. Momentous
- B. Sudden
- C. Innocuous
- D. Gradual
Correct answer: D
Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.
2. Stanton runs 2 miles twice a week and 3 miles once a week. If he runs every week, how many miles does he run in a year?
- A. 185
- B. 260
- C. 330
- D. 364
Correct answer: D
Rationale: To calculate how many miles Stanton runs in a year, we first find out how many miles he runs in a week. Running 2 miles twice a week is 2 x 2 = 4 miles, and running 3 miles once a week is an additional 3 miles. Therefore, in a week, Stanton runs a total of 4 + 3 = 7 miles. To find out how many miles he runs in a year, we multiply the weekly total by the number of weeks in a year (52): 7 miles/week x 52 weeks = 364 miles. Therefore, Stanton runs 364 miles in a year. Choice A (185) is incorrect as it does not account for the total weekly distance correctly. Choice B (260) is incorrect as it miscalculates the total miles run in a year. Choice C (330) is incorrect as it does not calculate the correct total distance covered by Stanton in a year.
3. 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.
4. Which of the following is not true about antibiotics?
- A. They can interfere with the bacteria's ability to survive
- B. They can affect how bacteria multiply
- C. They can cause more bacteria to grow
- D. They only work on bacteria
Correct answer: C
Rationale: The correct answer is C. Antibiotics do not cause more bacteria to grow. They work by interfering with the bacteria's ability to survive, affecting how they multiply, or killing the bacteria cells. Antibiotics specifically target bacteria, so they do not promote the growth of more bacteria. Choices A, B, and D are true statements about antibiotics as they accurately describe how antibiotics work and their specific action on bacteria.
5. Which of the following statements is a fact?
- A. Nurses should watch for jaundice in newborns.
- B. Untreated jaundice may cause brain damage.
- C. Phototherapy blankets are a valuable invention.
- D. Avoid neonatal units that lack phototherapy.
Correct answer: B
Rationale: The correct answer is B: 'Untreated jaundice may cause brain damage.' This statement is a fact supported by the passage. Neonatal jaundice, if left untreated, can lead to brain damage due to excess bilirubin levels in the blood. Choice A is not a fact but a general guideline for nurses. Choice C is an opinion as it describes phototherapy blankets as valuable without citing a specific fact. Choice D is not a fact but a recommendation, advising to avoid neonatal units lacking phototherapy.
