ATI Reading Comprehension Practice Test 2 — Questions and Answers
Question 1: A passage states: 'Nosocomial infections affect approximately 1.7 million patients annually in the United States, resulting in 99,000 deaths per year.' Based on this information, which conclusion is most accurate?
- Most hospital patients will develop nosocomial infections
- Nosocomial infections are a significant cause of morbidity and mortality (Correct answer)
- Hospitals are unsafe places for patients
- All nosocomial infections are preventable
Correct answer: Nosocomial infections are a significant cause of morbidity and mortality
The statistics support that nosocomial infections are a significant cause of morbidity (1.7M affected) and mortality (99,000 deaths), without overgeneralizing beyond the data.
Effective reading comprehension requires drawing conclusions that are directly supported by the text without overextending the evidence. The passage provides specific statistics about incidence and mortality, which directly support the conclusion about significance. Saying 'most patients' overgeneralizes (1.7M out of ~35M annual hospitalizations is about 5%). Calling hospitals 'unsafe' is an emotional interpretation not supported by the data. Claiming all infections are preventable adds information not present in the passage.
Question 2: Read the following: 'The hypothalamus regulates body temperature through a negative feedback mechanism. When body temperature rises above the set point, vasodilation and sweating are triggered. When it falls below, vasoconstriction and shivering occur.' What is the author's primary purpose?
- To argue that the hypothalamus is the most important brain structure
- To explain the mechanism of temperature regulation (Correct answer)
- To describe symptoms of hypothermia
- To compare the hypothalamus to a thermostat
Correct answer: To explain the mechanism of temperature regulation
The passage objectively explains how the hypothalamus regulates temperature through negative feedback, without making arguments or comparisons.
Identifying the author's purpose is a fundamental reading comprehension skill. This passage uses factual, explanatory language to describe a physiological mechanism — how the hypothalamus maintains homeostatic body temperature through negative feedback. The author is not arguing for the hypothalamus's importance (no evaluative language), not describing hypothermia symptoms specifically, and not making a thermostat comparison (even though the analogy would be apt). The purpose is purely explanatory, as indicated by the cause-and-effect structure.
Question 3: A passage describes a research study: 'Participants who received the experimental drug showed a 40% reduction in symptoms compared to the placebo group. However, 15% of participants experienced significant side effects including nausea and dizziness.' Which statement represents an inference from this passage?
- The drug reduced symptoms by 40%
- Some participants experienced nausea
- Healthcare providers would need to weigh the benefits against the side effect risks (Correct answer)
- Fifteen percent of participants had side effects
Correct answer: Healthcare providers would need to weigh the benefits against the side effect risks
An inference goes beyond what is explicitly stated. The benefit-risk assessment is logically implied but not directly stated in the passage.
Reading comprehension distinguishes between explicit information and inferences. Options A, B, and D are all explicitly stated in the passage. Option C represents an inference — a logical conclusion drawn from the presented facts but not directly stated. The passage presents both efficacy data (40% symptom reduction) and safety data (15% side effects), which logically implies that prescribers would need to perform a risk-benefit analysis. Making valid inferences from text is a higher-order comprehension skill tested on the HESI.
Question 4: In a passage about wound healing: 'The inflammatory phase, lasting 1-6 days, involves vascular response and cellular defense. Subsequently, the proliferative phase spans days 3-21, characterized by granulation tissue formation. Finally, the maturation phase may continue for up to 2 years.' What organizational pattern does this passage use?
- Compare and contrast
- Cause and effect
- Chronological/sequential order (Correct answer)
- Problem and solution
Correct answer: Chronological/sequential order
The passage organizes information in time-based sequential order, using temporal markers like 'subsequently' and 'finally' to describe phases in order.
Recognizing organizational patterns is essential for reading comprehension. This passage uses chronological/sequential order, clearly indicated by: time-based phase descriptions (days 1-6, days 3-21, up to 2 years), sequential transition words ('subsequently,' 'finally'), and the logical progression from one healing phase to the next. Compare-and-contrast patterns use words like 'however' or 'similarly.' Cause-and-effect uses 'because' or 'therefore.' Problem-solution presents a problem followed by resolution. The temporal framework here is unmistakably sequential.
Question 5: A passage reads: 'While antibiotics have saved countless lives since their discovery, their overuse has led to the emergence of antibiotic-resistant bacteria such as MRSA. Public health experts warn that without significant changes in prescribing practices, we may enter a post-antibiotic era.' The tone of this passage is best described as:
- Optimistic and encouraging
- Cautionary and concerned (Correct answer)
- Hostile and accusatory
- Neutral and indifferent
Correct answer: Cautionary and concerned
The passage acknowledges benefits but emphasizes risks with warning language ('warn,' 'post-antibiotic era'), creating a cautionary and concerned tone.
Tone analysis requires examining word choice, sentence structure, and overall message. The passage begins by acknowledging a positive ('saved countless lives') but pivots to concern ('overuse,' 'antibiotic-resistant,' 'warn,' 'post-antibiotic era'). The word 'warn' explicitly signals concern. The hypothetical 'post-antibiotic era' implies serious consequences. This is not hostile (no blame or accusatory language), not optimistic (the trajectory described is negative), and not neutral (the language carries clear emotional weight). The balanced-but-concerned approach is cautionary.
Question 6: Based on a passage: 'Nurse practitioners (NPs) have prescriptive authority in all 50 states, though scope of practice varies. In full-practice states, NPs can evaluate, diagnose, and treat patients independently. In restricted-practice states, NPs must maintain a collaborative agreement with a physician.' What is the main idea of this passage?
- Nurse practitioners should have full practice authority everywhere
- Physician collaboration improves patient outcomes
- NP prescriptive authority exists nationwide but practice scope varies by state (Correct answer)
- Full-practice states have better healthcare than restricted-practice states
Correct answer: NP prescriptive authority exists nationwide but practice scope varies by state
The main idea summarizes the central point: NPs have prescriptive authority everywhere, but the scope of independent practice varies by state regulation.
Identifying the main idea requires distinguishing the central message from supporting details and unsupported opinions. The passage presents two key facts: universal prescriptive authority and variable scope of practice. Option C accurately synthesizes these points. Option A adds an advocacy position not stated. Option B introduces a claim about outcomes not mentioned. Option D makes a quality comparison not supported by the passage. The main idea must reflect what the passage actually states, not what the reader might infer or believe.
