HESI A2 Reading Comprehension
1. What is the meaning of the word 'shifts' as used in the third paragraph?
- A. Alterations
- B. Stints
- C. Removals
- D. Transfers
Correct answer: A
Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.
2. What is the meaning of the word 'abstain' as used in the last paragraph?
- A. Dishonor
- B. Go without
- C. Connect to
- D. Liberate
Correct answer: B
Rationale: In the context of the passage, 'abstain' means to refrain from or go without. The passage discusses the challenges of treating individuals with both eating disorders and substance abuse issues. It mentions that while treatment for addiction involves abstinence, it is not possible to completely abstain from food. This highlights the meaning of 'abstain' as 'go without' in this context. The other choices are incorrect: 'Dishonor' does not relate to abstain, 'Connect to' is not synonymous with abstain, and 'Liberate' does not align with the context of the passage.
3. All of the following are mentioned in the passage as potential risks from inadequate sleep EXCEPT ___________.
- A. Cancer
- B. Obesity

Rationale: Cancer is not mentioned as a risk associated with inadequate sleep in the passage.
4. Sleeping apparently helps with everything EXCEPT ___________.
