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. Which sentence is grammatically correct?

A. Somebody left their jacket on the train
B. Somebody left his or her jacket on the train
C. His jacket was left on the train
D. His or her jacket was left on the train

Correct answer: B

Rationale: The sentence 'Somebody left his or her jacket on the train.' is grammatically correct and respects gender neutrality. 'Somebody' is singular, so the pronoun 'their' in choice A is incorrect. Choice C changes the subject from 'somebody' to 'his,' making it grammatically incorrect. Choice D is grammatically correct, but it is less concise and more awkward than choice B, which smoothly combines 'his' and 'her' for gender-neutral language.

3. The development of the disease was INSIDIOUS.

A. Momentous
B. Sudden
C. Innocuous
D. Gradual

Correct answer: D

Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.

4. What does 'Fatal' mean?

A. Resulting in injury
B. Resulting in death
C. Dangerous
D. Treatable

Correct answer: B

Rationale: The correct answer is B: 'Resulting in death.' The term 'Fatal' specifically means resulting in death. Choices A, C, and D are incorrect because 'Fatal' does not refer to resulting in injury, being dangerous, or being treatable.

5. Choose the meaning of the word 'distended' in the following sentence: 'The patient's distended veins were a cause for worry.'

A. Bleeding
B. Enlarged
C. Pressure
D. Minuscule

Correct answer: B

Rationale: The term 'distended' means swollen or enlarged. In this context, when the patient's veins are described as distended, it implies that they are expanded or swollen beyond their normal size, which can be a cause for worry due to potential health implications. Choice A ('Bleeding') is incorrect as 'distended' does not refer to bleeding but rather to being swollen. Choice C ('Pressure') is incorrect as 'distended' does not directly imply pressure but rather enlargement. Choice D ('Minuscule') is incorrect as 'distended' means the opposite of minuscule, indicating something enlarged or swollen.
