HESI A2 Practice Vocabulary

1. What is the process of digestion?

Correct answer: B

Rationale: The correct answer is B: The mechanical and chemical breakdown of food. Digestion involves breaking down food mechanically and chemically into smaller components for absorption by the body. This process occurs in the digestive system, preparing nutrients for absorption in the intestines. Choices A, C, and D are incorrect because digestion is not solely about the production of enzymes, absorption of nutrients in the blood, or movement of enzymes; it primarily involves breaking down food for nutrient absorption.

2. Did the interns contravene the doctor's orders?

Correct answer: B

Rationale: The correct answer is 'B: Disregard.' Contravene means to violate or disregard rules or orders. In this context, the question is asking whether the interns went against or disobeyed the doctor's orders. Choices 'A: Follow,' 'C: Exceed,' and 'D: Respect' do not align with the meaning of contravene in this context. Following, exceeding, or respecting the doctor's orders would mean the interns did not contravene them.

3. The development of the disease was 'insidious'. What does insidious mean in this context?

Correct answer: A

Rationale: In this context, 'insidious' means progressing slowly but having harmful effects. This matches the meaning of 'gradual,' making it the correct answer. 'Momentous' means significant or important, which is not the meaning conveyed by 'insidious.' 'Sudden' means abrupt or unexpected, opposite to the slow progression indicated by 'insidious.' 'Innocuous' means harmless, which is the opposite of the harmful effects associated with an insidious disease.

4. What is the best description for the abbreviation CDC?

Correct answer: D

Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.

5. Which phrase best completes the sentence: 'Despite _____, he managed to complete the race.'

Correct answer: A

Rationale: The correct answer is 'A: his injury.' In the context of completing a race, an injury would be a significant obstacle to overcome. While choices B, C, and D could also pose challenges, an injury is the most severe hindrance that would make completing a race particularly difficult. His condition, pain, or fatigue may affect performance, but they are not as directly impactful as an injury in this scenario.
