HESI A2 Vocabulary Practice Test

1. What is the meaning of Collusion?

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.

2. Choose the meaning of the word 'intramuscularly' in the following sentence: 'This vaccine must only be used intramuscularly and as a single-dose vial.'

Correct answer: B

Rationale: The word 'intramuscularly' in the sentence indicates that the vaccine should be used by injection directly into the muscles. This means the correct meaning is 'into muscles,' making option B the most suitable choice. Choices A, C, and D are incorrect because 'intramuscularly' specifically refers to administering something inside the muscle, not between muscles, without muscles, or on top of muscles.

3. A patient's weight is measured as 75 kilograms. What is their weight in pounds?

Correct answer: B

Rationale: Rationale: To convert kilograms to pounds, you can use the conversion factor 1 kilogram is approximately equal to 2.20462 pounds. Therefore, to convert 75 kilograms to pounds: 75 kilograms * 2.20462 pounds/kilogram ≈ 165.3475 pounds Rounded to the nearest whole number, the patient's weight of 75 kilograms is approximately 165 pounds. Among the given options, the closest weight in pounds to 165 is 150 pounds (option B).

4. Which structure in the ear is responsible for balance?

Correct answer: B

Rationale: The semicircular canals in the inner ear are responsible for maintaining balance by detecting changes in head position and movement. These structures contain fluid and hair cells that send signals to the brain regarding the body's orientation in space, helping us stay balanced and navigate our surroundings. The cochlea is responsible for hearing, the ossicles are involved in sound transmission, and the Eustachian tube helps equalize pressure in the middle ear, but they are not directly related to balance.

5. Which sentence uses the correct form of the verb?

Correct answer: B

Rationale: The correct answer is 'She has completed the project.' The sentence uses the present perfect tense with 'has completed,' which is the correct form of the verb. Choice A is incorrect due to the subject-verb agreement error ('She' requires 'has' instead of 'have'). Choice C is incorrect as it changes the meaning by using the passive voice 'has been completed' instead of the active voice. Choice D is incorrect as 'complete' should be 'completed' to match the present perfect tense.
