Vocabulary HESI A2 Practice Test

1. What does instigate mean?

Correct answer: B

Rationale: The correct answer is B: 'Activate.' Instigate means to initiate or provoke a particular event or action. Choice A, 'Deactivate,' is incorrect as it means to make something inactive, which is the opposite of instigate. Choice C, 'Suppress,' is incorrect as it means to restrain or prevent something, not to initiate it. Choice D, 'Evaluate,' is incorrect as it means to assess or judge the value or quality of something, not to start or provoke it.

2. What is the primary function of the cardiovascular system?

Correct answer: A

Rationale: The correct answer is A: "To transport oxygen and nutrients." The primary function of the cardiovascular system is to transport oxygen, nutrients, and hormones to cells throughout the body and remove waste products. This system plays a crucial role in maintaining homeostasis by delivering essential substances to tissues and organs while eliminating metabolic waste. Choices B, C, and D are incorrect because although the cardiovascular system indirectly helps in removing waste products through circulation, its primary function is focused on transporting essential substances and not on regulating body temperature or fighting infections.

3. After taking several practice tests, Brian improved the results of his GRE test by 30%. Given that the first time he took the test Brian answered 150 questions correctly, how many questions did he answer correctly on the second test?

Correct answer: D

Rationale: If Brian answered 150 questions correctly on the first test, after improving his results by 30%, he would have answered (150 * 1.30) = 195 questions correctly on the second test. Therefore, the correct answer is 195, option D. Choices A, B, and C are incorrect as they do not account for the 30% improvement in the number of questions Brian answered correctly on the second test.

4. What is the primary function of the cardiovascular system?

Correct answer: A

Rationale: The correct answer is A: 'To transport oxygen and nutrients.' The primary function of the cardiovascular system is to transport oxygen, nutrients, and hormones to cells throughout the body and remove waste products. Choice B is incorrect because regulating body temperature is primarily the function of the body's thermoregulatory system, including sweat glands and blood vessels near the skin surface. Choice C is incorrect because while the cardiovascular system does help remove waste products through circulation, it is not its primary function. Choice D is incorrect as hormone production is mainly carried out by endocrine glands, not the cardiovascular system.

5. Subtract 32 divided by 8\9.

Correct answer: A

Rationale: 32 ÷ (8\9) is the same as 32 × (9\8) = 36.
