Vocabulary HESI A2 Practice Test

1. What does Labile mean?

A. Stable
B. Changing rapidly and often
C. Unchanging
D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

2. As the leader of a group, the charge nurse is open to new ideas and thoughts of the group. The charge nurse encourages the group to participate in making decisions. This type of leadership is called:

A. Laissez-faire
B. Autocratic
C. Democratic
D. Direct

Correct answer: C

Rationale: The correct answer is 'Democratic.' A 'Democratic' leadership style involves the leader being open to new ideas and thoughts from the group and encourages group participation in decision-making. This style promotes collaboration, communication, and inclusivity in decision-making processes. 'Laissez-faire' leadership is characterized by a hands-off approach with minimal guidance or direction. 'Autocratic' leadership is where the leader makes decisions without much input from the group. 'Direct' leadership is not a widely recognized leadership style in this context.

3. What sentence should replace the following incorrect sentence? 'This door to remain unlocked during business hours.'

A. This business must have the door unlocked at all times.
B. This door to remain unclosed while open.
C. This sentence is corrected as written.
D. This door will remain unlocked when the business is open.

Correct answer: D

Rationale: The original sentence is incorrect due to awkward phrasing. Choice D, 'This door will remain unlocked when the business is open,' provides a clear and concise correction, specifying that the door should be unlocked only when the business is open. Choices A and B do not address the timing aspect of unlocking the door, making them incorrect. Choice C is incorrect as the original sentence needs a revision to clarify the intended meaning.

4. Which muscle in the shoulder is the deltoid?

A. dendrite
B. delphic
C. deltoid
D. dentate

Correct answer: C

Rationale: The deltoid muscle is located in the shoulder area. It is a rounded, triangular muscle that covers the shoulder joint and is responsible for lifting the arm and providing shoulder stability. The other options provided, dendrite, delphic, and dentate, are not muscles in the shoulder region.

5. Everyone thought that was the __________ test of the whole course.

A. Most easiest
B. Most easy
C. Easiest
D. Easy

Correct answer: C

Rationale: The correct answer is C: 'Easiest.' The word 'easiest' is the correct superlative form of 'easy,' which is used to compare one item against others in terms of degree. 'Most easiest' and 'most easy' are grammatically incorrect. Choice D, 'Easy,' is incorrect as it is not a superlative form and does not convey a comparison of the test against others in the course.
