Reading Comprehension HESI A2 Practice Test

1. What conclusion is suggested by this study from Germany?

A. So far, acupuncture does not have much credibility as a treatment option.
B. Acupuncture can relieve women of all menstrual discomfort.
C. NSAIDs are generally more effective than acupuncture for treating cramps.
D. Acupuncture is a reasonable treatment choice for cramps.

Correct answer: D

Rationale: The study indicates that acupuncture is a reasonable treatment option for menstrual cramps, supported by the positive outcomes reported by participants in the study. The wording in option D directly aligns with the conclusion drawn from the findings, making it the correct answer.

2. Which statement is not listed as a detail within the passage?

A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
B. The signal has a characteristic record called the electrocardiogram.
C. The 'wave of excitation' starts at the SA node.
D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.

Correct answer: A

Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.

3. What is the meaning of the word 'phenomenon' in the second paragraph?

A. Something that is lifeless to the senses
B. Something that is nonchalant
C. Something that is significant but unusual
D. Something that is chemical in origin

Correct answer: C

Rationale: In the context of the second paragraph, 'phenomenon' refers to something significant and unusual, specifically describing the scientific phenomenon known as the Doppler Effect. This effect explains the change in frequency of sound waves when a source of sound and the observer are in relative motion. Choices A, B, and D are incorrect because they do not accurately reflect the meaning of 'phenomenon' in this context. 'Lifeless to the senses,' 'nonchalant,' and 'chemical in origin' do not align with the description of the Doppler Effect, which is a notable and uncommon scientific occurrence.

4. What is the meaning of the word 'composed' in the first paragraph?

A. To consist of
B. To be uniquely discovered
C. To be set apart
D. To be surprised

Correct answer: A

Rationale: In the context provided, 'composed' means to consist of. The paragraph explains that a drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is A. Choice B, 'To be uniquely discovered,' is incorrect as it does not relate to the composition of a drop of water. Choice C, 'To be set apart,' and Choice D, 'To be surprised,' are also incorrect as they do not convey the meaning of 'composed' as it is used in this paragraph.
