Vocabulary HESI A2

1. 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.

2. What does the word Quarantine mean?

A. Isolation
B. Confinement away from the general population
C. Treatment
D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

3. What does bifurcate mean?

A. Fold twice
B. Flower biannually
C. Divide in two forks
D. Pierce two openings

Correct answer: C

Rationale: Bifurcate means to divide into two forks or branches. It comes from the Latin word "bi" meaning two and "furca" meaning fork. So, when something bifurcates, it splits into two separate paths or divisions. Choice A, "Fold twice," is incorrect as bifurcate doesn't involve folding. Choice B, "Flower biannually," is unrelated to the meaning of bifurcate. Choice D, "Pierce two openings," is also incorrect as it does not capture the true essence of bifurcate, which is about dividing into two forks or branches.

4. Select the meaning of the word 'holistic' in the sentence: 'Dr. Grant ignored Mary's particular symptoms, instead administering a holistic treatment.'

A. insensitive
B. ignorant
C. specialized
D. concerned with the whole

Correct answer: D

Rationale: In this context, 'holistic' means concerned with the whole person, considering physical, mental, and social factors, rather than just addressing specific symptoms. Therefore, the correct answer is D. Choices A, B, and C are incorrect because 'holistic' does not mean insensitive, ignorant, or specialized in this context.

5. Select the meaning of the underlined word in the following sentence. Quick action kept the disease from permeating the general population.

A. Conquering
B. Wounding
C. Deterring
D. Infiltrating

Correct answer: D

Rationale: In this context, the word 'permeating' indicates the process of spreading throughout or penetrating into. 'Infiltrating' is the most appropriate synonym for this meaning, as it captures the idea of the disease spreading into the general population. 'Conquering' (Choice A) means to overcome or defeat, which is not the meaning in this context. 'Wounding' (Choice B) means to cause injury, which is not relevant to the sentence. 'Deterring' (Choice C) means to discourage or prevent, which does not fit the context of the disease spreading.
