HESI A2 Practice Test Vocabulary
1. An apartment is advertised as being furnished. What does the sentence mean?
- A. It is equipped with articles
- B. It has just been repainted
- C. The first month’s rent must be paid in advance
- D. The utility bills are included in the rental cost
Correct answer: A
Rationale: The correct answer is A: 'It is equipped with articles.' In real estate terms, when an apartment is advertised as 'furnished', it means that the apartment comes equipped with furniture and other necessary items. This choice directly reflects the meaning of a furnished apartment. The other choices are incorrect because being furnished does not imply that the apartment has just been repainted (B), requires the first month’s rent to be paid in advance (C), or includes utility bills in the rental cost (D).
2. What is the meaning of Collusion?
- A. Cooperation
- B. Conspiracy
- C. Separation
- D. Rejection
Correct answer: B
Rationale: The correct answer is B: 'Conspiracy.' Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. Choice A, 'Cooperation,' is incorrect as collusion implies a deceptive or dishonest agreement, not a genuine cooperation. Choice C, 'Separation,' is incorrect as it denotes the opposite of collusion, which involves working together secretly. Choice D, 'Rejection,' is unrelated to collusion, which involves secret cooperation for deceptive purposes.
3. Select the word that makes the following sentence grammatically correct. It is important that one is able to self-motivate and work by ___________.
- A. oneself
- B. oneselves
- C. hisself
- D. themselves
Correct answer: A
Rationale: The word 'oneself' is a reflexive pronoun that refers back to the subject of the sentence, allowing the sentence to be grammatically correct. Options B and C, 'oneselves' and 'hisself,' are not standard English words. Option D, 'themselves,' is a plural pronoun and does not agree with the singular noun 'one' in the sentence.
4. Which of the following is true of Glycolysis?
- A. It requires the absence of Oxygen
- B. It occurs in the presence of Oxygen
- C. It is the final step of fermentation
- D. It is the final step of anaerobic respiration
Correct answer: B
Rationale: Glycolysis is the first step in cellular respiration and can occur in both aerobic (presence of oxygen) and anaerobic (absence of oxygen) conditions. In aerobic respiration, glycolysis takes place in the presence of oxygen and continues with the Krebs cycle and the electron transport chain. So, glycolysis does not require the absence of oxygen but can occur in its presence as part of the overall process of aerobic respiration. Choice A is incorrect because glycolysis can occur in the presence of oxygen. Choice C is incorrect because glycolysis is not the final step of fermentation; it is the initial step. Choice D is incorrect because glycolysis is not the final step of anaerobic respiration; it is the first step, followed by further processes to complete anaerobic respiration.
5. Cobalt-60 has a half-life of 5 years. If you start with 20 g of cobalt-60, how much is left after 10 years?
- A. 15 g
- B. 10 g
- C. 5 g
- D. 2.5 g
Correct answer: C
Rationale: Cobalt-60's half-life of 5 years means that after 5 years, half of the initial amount remains. Therefore, after 10 years, a quarter (half of a half) of the initial amount will remain. Starting with 20 g, after 10 years, 5 g of cobalt-60 will be left. Choice A (15 g) is incorrect because it assumes a linear decrease, not considering the exponential decay characteristic of radioactive substances. Choice B (10 g) is incorrect as it overlooks that after 10 years, more decay has occurred. Choice D (2.5 g) is incorrect as it represents only an eighth of the initial amount after 10 years, not a quarter.
