- The passage primarily focuses on...
Answer: an analysis of the benefits of telehealth contrasted with its associated challenges and limitations.
When you encounter reading comprehension questions asking what a passage "primarily focuses on," you need to identify the main organizational pattern and central theme that runs throughout the entire text.
This passage follows a balanced analytical structure: it begins by introducing telehealth, then systematically presents its advantages (geographic accessibility, efficiency for chronic care, reduced costs), followed by its challenges (digital divide, privacy concerns, examination limitations), and concludes with a future outlook combining both perspectives. The author dedicates roughly equal attention to benefits and drawbacks, creating a comprehensive analysis rather than advocating for one side.
Answer C correctly captures this balanced approach—the passage analyzes telehealth's benefits while contrasting them with challenges and limitations. This two-sided examination forms the backbone of the entire discussion.
Answer A is wrong because the passage contains no technical details about platform operations—it discusses telehealth conceptually, not mechanistically. Answer B is incorrect because while the passage mentions some comparative elements, it doesn't present systematic outcome data or research comparing telehealth versus traditional care effectiveness. Answer D is wrong because there's no historical timeline or development account—the passage mentions evolution briefly but focuses on current advantages and challenges.
For HESI reading questions about main focus, look for the organizational structure that dominates the passage. Balanced presentations of pros and cons, like this one, typically aim to analyze rather than explain technical details, compare specific data, or provide historical context. Identify what gets the most textual real estate and shapes the overall argument.
- A key point emphasized in the passage is that...
Answer: consistency in one's sleep-wake schedule is crucial for supporting the body's natural circadian rhythm.
When you encounter reading comprehension questions about health practices, focus on identifying the main principles the passage emphasizes rather than getting distracted by contradictory details in the answer choices.
The passage clearly states that maintaining "a consistent sleep-wake schedule, even on weekends" is essential "to regulate the body's internal clock, or circadian rhythm." This direct statement supports answer choice C, which correctly identifies consistency in sleep-wake schedules as crucial for supporting natural circadian rhythms.
Now let's examine why the other options are wrong. Choice A claims blue light enhances sleep quality, but the passage explicitly states that "exposure to bright light, particularly blue light from electronic screens, before bedtime can suppress the production of melatonin." Choice B suggests caffeine helps regulate sleep, when the passage actually recommends "avoiding stimulants like caffeine and nicotine late in the day." Choice D promotes a warm, brightly lit room for melatonin production, but the text specifies that the sleep environment "should be dark, quiet, and cool," and that bright light suppresses melatonin production.
Notice how choices A, B, and D all present the opposite of what the passage recommends—these are classic distractor patterns designed to test whether you're reading carefully.
For HESI reading questions, always return to the passage to verify claims made in answer choices. Don't rely on outside knowledge or assumptions. The correct answer will have direct textual support, while wrong answers often contradict the passage's explicit statements.
- What is the central idea the passage conveys about achieving good sleep?
Answer: Good sleep is primarily the result of a multifaceted approach involving consistent routines and a controlled environment.
When you encounter reading comprehension questions asking for the "central idea," you need to identify the main theme that ties together all the details in the passage, rather than focusing on individual components.
The passage presents sleep hygiene as a comprehensive approach involving multiple interconnected practices. Notice how it mentions "key components" (plural) and describes how various elements "work in concert" - consistent sleep schedules, environmental controls (dark, quiet, cool), managing light exposure, pre-sleep rituals, and avoiding stimulants. The phrase "multifaceted approach" in answer choice B directly captures this collaborative relationship between different sleep hygiene practices.
Let's examine why the other options miss the mark. Choice A incorrectly elevates one element (consistent bedtime) as the "single most important factor," but the passage treats all components as working together rather than ranking them. Choice C overemphasizes melatonin production as the primary determinant of sleep quality, when the passage mentions melatonin only as one factor affected by light exposure. Choice D focuses solely on the physical environment, ignoring the behavioral aspects like consistent schedules and pre-sleep routines that the passage emphasizes equally.
The correct answer is B because it recognizes that good sleep results from combining consistent routines with environmental controls - the holistic approach the passage advocates.
Study tip: On HESI reading questions about central ideas, look for language that signals how multiple concepts work together (words like "components," "in concert," "work together"). The central idea usually encompasses the relationship between all major points, not just one dominant factor.
- The passage as a whole is primarily concerned with...
Answer: defining sleep hygiene and outlining its principal components.
When you encounter reading comprehension questions asking what a passage is "primarily concerned with," you need to identify the main purpose or central focus of the entire text, not just specific details mentioned within it.
This passage opens by defining sleep hygiene as "a set of behavioral and environmental practices that are intended to promote better quality sleep," then systematically outlines the key components: maintaining consistent sleep schedules, creating proper sleep environments, avoiding blue light exposure, establishing pre-sleep rituals, and avoiding stimulants. The structure moves from definition to explanation of principal elements, making the primary concern clear.
Looking at the incorrect choices: Choice A is wrong because the passage doesn't compare medical treatments for insomnia at all—it focuses on behavioral practices, not medical interventions. Choice B incorrectly narrows the focus to hormonal mechanisms; while melatonin is mentioned, it's just one component supporting the broader discussion of sleep hygiene practices. Choice D mischaracterizes the passage's tone and purpose—there are no warnings about public health dangers from sleep deprivation. The passage maintains an educational, informative tone about promoting good sleep rather than warning about consequences of poor sleep.
Choice C correctly captures the passage's dual purpose: it both defines what sleep hygiene means and systematically explains its main components (schedule consistency, environment control, light exposure management, and pre-sleep routines).
For HESI reading questions, always distinguish between the main purpose and supporting details. Ask yourself: "What is this entire passage trying to accomplish?" rather than focusing on individual facts mentioned along the way.
- According to the passage, what is a key point regarding the role of a healthcare provider in the placebo effect?
Answer: A provider's conviction and the psychosocial context they create can significantly influence the strength of the effect.
When you encounter questions about the placebo effect on the HESI, focus on understanding it as a genuine mind-body phenomenon rather than just "fake" medicine. The passage emphasizes that placebo effects produce real physiological changes through psychological mechanisms.
The correct answer is B because the passage directly states that "when a trusted healthcare provider administers a treatment with conviction, it can create a powerful expectancy that initiates the body's own healing processes." The text also emphasizes "the importance of the psychosocial context of the therapeutic encounter," showing that the provider's approach and the overall treatment environment significantly influence the placebo effect's strength.
Choice A is too extreme—while provider skepticism might weaken the effect, the passage doesn't suggest it can "completely nullify" it. Choice C misrepresents the mechanism entirely; the passage shows the effect stems from expectation and belief, not necessarily deception. The provider doesn't need to lie—they just need to create positive expectations. Choice D contradicts the passage's clear emphasis on the provider's role and the "psychosocial context," suggesting external factors don't matter when the text explicitly argues they do.
For HESI questions about healthcare concepts, pay attention to nuanced relationships rather than black-and-white thinking. The placebo effect illustrates how psychological and social factors genuinely impact physical health outcomes—a key principle in holistic nursing care that frequently appears on the exam.
- Based on the passage, which statement best summarizes the key relationship between CKD progression and patient management?
Answer: Early detection through screening is crucial because CKD is initially asymptomatic, and timely management can slow disease progression before irreversible damage occurs.
Choice B correctly identifies the key relationship described in the passage: early CKD stages are asymptomatic, making screening important for at-risk populations, and management focuses on slowing progression. The passage emphasizes that early detection allows for interventions that can slow disease advancement. Choice A is incorrect because the passage states management focuses on slowing progression, not just preparing for end-stage treatment. Choice C is wrong because Stage 5 represents kidney failure requiring dialysis/transplant, not the optimal time for management. Choice D misrepresents the passage's emphasis on slowing progression rather than just treating symptoms.
- The passage is primarily concerned with...
Answer: explaining the nature, mechanism, and significance of the placebo effect.
When you encounter reading comprehension questions asking what a passage is "primarily concerned with," you're being tested on your ability to identify the main purpose and overall focus of the text, not just supporting details.
This passage systematically explores the placebo effect from multiple angles. It begins by defining what the placebo effect is, then explains that it produces real physiological changes (not just imagination), describes the underlying mechanism (patient expectation and belief), and concludes by discussing its broader significance in understanding mind-body connections in medicine. The author takes you through a complete examination of this phenomenon.
Looking at the wrong answers: Choice A is incorrect because the passage never mentions ethical guidelines or research protocols. Choice B misses the mark entirely—the passage doesn't criticize modern medicine or pharmaceutical treatments at all. Choice D is wrong because the passage doesn't provide instructions for patients to self-administer placebo effects; it simply explains how the effect works scientifically.
Choice C correctly captures the passage's comprehensive approach: explaining the nature (what it is), mechanism (how expectation triggers physiological responses), and significance (importance for understanding therapeutic relationships and mind-body medicine).
For HESI reading questions, always distinguish between the main purpose and supporting details. Wrong answers often focus on narrow aspects mentioned in the passage or introduce topics not discussed at all. The correct answer should encompass the passage's overall goal and primary focus, not just one paragraph or example.
- What is the central idea presented about the placebo effect?
Answer: It is a demonstrable physiological response influenced by psychological factors like expectation and belief.
When you encounter questions about medical concepts like the placebo effect, focus on identifying what the passage emphasizes as the main point rather than getting distracted by secondary details mentioned briefly.
The passage clearly establishes that the placebo effect is a legitimate, measurable phenomenon with real physiological consequences. The text provides concrete evidence: brain imaging studies show placebos trigger endogenous opioid release and affect brain areas linked to pain and reward. This demonstrates it's not "just in the patient's head" but involves actual biological processes. The passage emphasizes that these physical responses are driven by psychological factors—specifically patient expectation and belief in treatment efficacy, especially when administered by trusted healthcare providers. Answer B captures this central theme perfectly.
Looking at the incorrect options: Answer A misrepresents the passage, which states placebos are "often viewed as a nuisance" but doesn't claim researchers have eliminated them—in fact, the passage suggests they're important to understand. Answer C contradicts the text entirely; nothing suggests the placebo effect is rare or unpredictable. Answer D completely misses the point and introduces the concept of fraud, which isn't mentioned or implied anywhere in the passage.
For HESI reading comprehension questions, always identify the author's main argument or emphasis. Look for phrases like "highlights," "underscores," or "the primary mechanism" that signal what the author considers most important. Don't be misled by minor points mentioned only briefly—focus on what receives the most explanation and support.
- What is the best summary of the passage on cellular senescence?
Answer: Cellular senescence is a biological defense against cancer that also has the negative consequence of promoting age-related diseases.
When you encounter reading comprehension questions about complex biological processes, focus on identifying the main theme and balanced perspective the author presents, rather than getting caught up in specific details.
The passage presents cellular senescence as a double-edged sword. Initially described as "a crucial anti-cancer mechanism" that prevents damaged cells from becoming malignant, the text then reveals "a darker side" where accumulated senescent cells secrete inflammatory proteins (SASP) that contribute to age-related diseases. The author maintains this balanced view throughout, acknowledging both the protective and harmful aspects of the process.
Choice B correctly captures this dual nature, recognizing cellular senescence as both a cancer defense mechanism and a contributor to age-related diseases. This mirrors the passage's structure and tone.
Choice A is too extreme, calling senescence "wholly detrimental" and suggesting it "must be eliminated," which ignores the anti-cancer benefits discussed in the passage. Choice C contains a fundamental error—it describes senescence as "cell death," when the passage explicitly states senescent cells "do not die" but instead stop dividing. Choice D misrepresents the primary role, suggesting the main purpose is secreting inflammatory proteins, when SASP is actually described as a consequence, not the primary function.
For HESI reading questions, watch for passages that present scientific concepts with both positive and negative aspects. The correct answer often reflects this nuanced balance rather than taking an extreme position. Always verify that your chosen answer aligns with the passage's overall tone and key factual details.
- What is the key point made in the passage regarding the future of telehealth?
Answer: It will likely be integrated with traditional care in a hybrid approach to balance its strengths and weaknesses.
When you encounter reading comprehension questions about healthcare trends or policy, focus on identifying the author's main conclusions rather than getting distracted by supporting details or examples.
The passage explicitly states in its final sentence that "the future of telehealth likely involves a hybrid model, integrating virtual services with traditional in-person care to maximize benefits while mitigating risks." This directly supports answer choice C, which accurately captures the author's prediction that telehealth will be combined with traditional care methods to balance strengths and weaknesses.
Let's examine why the other options miss the mark. Choice A incorrectly suggests telehealth will be replaced by AI diagnostic tools, but the passage doesn't mention artificial intelligence at all. Choice B claims telehealth will become the sole healthcare delivery method, which contradicts the passage's emphasis on integration rather than replacement. Choice D restricts telehealth's future to only remote rural areas, but the passage discusses broader applications including chronic disease management and routine follow-ups for various patient populations.
The key insight is that the author presents telehealth as having both significant advantages (geographic accessibility, efficiency) and notable limitations (digital divide, privacy concerns, physical examination constraints). The logical conclusion is a balanced approach that leverages telehealth's strengths while using traditional care to address its weaknesses.
For HESI reading questions, always look for the author's explicit conclusions, especially in the final sentences of passages. Authors often save their main points for the end, making careful attention to concluding statements essential for identifying correct answers.
- Which of the following sentences best summarizes the passage on the placebo effect?
Answer: The placebo effect is a mind-body phenomenon where belief can trigger real physiological changes, affecting both research and clinical practice.
When you encounter reading comprehension questions asking for the main idea or summary, focus on identifying the passage's central theme and key supporting points rather than getting caught up in specific details.
The passage presents the placebo effect as a legitimate mind-body phenomenon with measurable physiological impacts. The author emphasizes that placebo effects produce "real physiological or psychological improvement" through mechanisms like endogenous opioid release and brain modulation. The key message is that patient belief and expectation can trigger actual healing processes, highlighting the important connection between psychological and physical aspects of medicine.
Answer B correctly captures this central theme by identifying the placebo effect as a "mind-body phenomenon where belief can trigger real physiological changes." It also acknowledges the broader implications for both research and clinical practice mentioned in the passage.
Answer A is wrong because it contradicts the passage's emphasis that placebo effects are "not merely imagined" and involve real physiological changes. Answer C misrepresents the passage by suggesting placebos prove conventional medicine is unnecessary—the passage never makes this claim and actually positions placebos within the context of legitimate medical practice. Answer D is too narrow, focusing only on endogenous opioids and pain treatment when the passage describes broader applications including "physiological or psychological improvement" beyond just pain conditions.
For HESI reading questions, always look for answer choices that capture the passage's main point without overstating, understating, or distorting the author's message. Avoid answers that focus on minor details while missing the bigger picture.
- The passage is primarily concerned with which aspect of the gut microbiome?
Answer: The symbiotic role of the microbiome in human physiology and its susceptibility to imbalance.
When you encounter reading comprehension questions asking what a passage is "primarily concerned with," you need to identify the main theme that runs throughout the entire text, not just isolated details or examples.
This passage presents the gut microbiome as a complex ecosystem that maintains a beneficial partnership with humans through multiple functions: digesting carbohydrates, producing vitamins, training the immune system, and even communicating with the brain. Crucially, the passage emphasizes that this relationship can be disrupted by various factors, leading to disease. The central theme is this dual nature - both the beneficial symbiotic relationship and its vulnerability to imbalance.
Answer choice A focuses only on specific bacterial species, but the passage discusses the microbiome broadly without detailing particular species. Answer choice C suggests the passage covers historical discovery and medical impact, yet there's no mention of when the microbiome was discovered or its historical significance to medicine. Answer choice D implies the passage describes research methods, but while the text mentions "recent research," it doesn't explain how scientists actually study these interactions.
Answer choice B correctly captures the passage's dual focus: the symbiotic benefits the microbiome provides (digestion, vitamin production, immune training, gut-brain communication) and how this delicate system can be disrupted (by diet, stress, antibiotics), leading to dysbiosis and chronic disease.
For HESI reading questions, always look for the thread that connects all paragraphs rather than getting distracted by specific examples or supporting details. The main idea usually encompasses both the primary concept and any significant complications or contrasts presented.
- Based on the passage, what represents the most fundamental shift in thinking that modern patient safety approaches require from traditional healthcare perspectives?
Answer: Transitioning from blaming individual providers for errors toward analyzing and improving the systems and processes that contribute to error occurrence.
Choice C correctly identifies the fundamental paradigm shift described in the passage: moving from viewing errors as individual failures to recognizing them as system failures. The passage explicitly states that "errors typically result from system failures rather than individual incompetence or negligence" and emphasizes systems approaches. Choice A discusses population health, which isn't the focus of the patient safety content presented. Choice B describes proactive versus reactive approaches, which is one strategy but not the fundamental shift in thinking described. Choice D addresses care settings rather than the conceptual shift from individual blame to systems thinking that the passage emphasizes as central to modern patient safety.
- Which sentence best summarizes the main idea of the second paragraph?
Answer: Despite its advantages, telehealth faces significant hurdles related to equity, security, and clinical practice.
When you encounter a passage with multiple paragraphs on the HESI, you need to identify the specific focus of each paragraph rather than the overall theme. The second paragraph of this telehealth passage shifts from discussing benefits to examining drawbacks and limitations.
The correct answer is C because the second paragraph systematically presents three major categories of telehealth challenges: equity issues (the "digital divide" affecting those without internet access or tech skills), security concerns (patient privacy and data protection), and clinical limitations (difficulty performing remote physical exams that can delay diagnosis). The paragraph structure moves from acknowledging benefits exist to introducing these "significant challenges" with specific examples in each category.
Answer A is too narrow because it focuses only on geographic access, ignoring the multiple challenges discussed. The paragraph mentions rural patients as one benefit in the first paragraph, not as the main limitation being addressed. Answer B incorrectly reduces the problems to just technical and connectivity issues, missing the broader equity, security, and clinical practice concerns. Answer D misrepresents the passage by suggesting clinician resistance is the main issue, when the paragraph actually describes objective limitations of remote physical examination rather than provider attitudes.
For HESI reading comprehension questions, pay close attention to paragraph transitions and topic sentences. When a paragraph begins with "Despite these benefits, significant challenges remain," you know the main idea will focus on those challenges, not the benefits mentioned earlier.
- What is the primary challenge in pain management that underlies most other assessment and treatment difficulties described in the passage?
Answer: The subjective nature of pain creates inherent assessment challenges that affect treatment decisions, especially in vulnerable populations.
Choice C identifies the fundamental challenge described in the passage: pain is "fundamentally a subjective experience that cannot be directly measured," which creates assessment difficulties, especially in populations unable to communicate effectively. This subjectivity underlies many other challenges mentioned. Choice A is incorrect because the passage doesn't suggest that distinguishing pain types is the primary difficulty. Choice B misrepresents the passage, which describes multiple available non-pharmacological options. Choice D overstates the impact of opioid concerns and incorrectly suggests effective options have been eliminated rather than that multimodal approaches are emphasized.
- According to the passage, what represents the greatest gap in addressing medication non-adherence in clinical practice?
Answer: Healthcare providers' inability to accurately identify which patients are non-adherent, combined with the need for individualized intervention approaches.
Choice B correctly identifies the key gap described in the passage: providers correctly identify non-adherent patients only 10-40% of the time, and successful interventions must be individualized rather than generic. This represents a fundamental disconnect between detection and appropriate response. Choice A is incorrect because the passage mentions electronic reminders and other technological solutions as available interventions. Choice C addresses standardization not specifically discussed in the passage. Choice D misrepresents the content, as the passage describes multiple known barriers and various evidence-based interventions, suggesting the issue isn't lack of research but rather implementation and individualization.
- According to the passage, what is a key point regarding the microbiome's relationship with the human body?
Answer: It is a cooperative, symbiotic relationship that provides mutual benefits for the host and microbes.
When you encounter questions about microorganisms and human health, focus on understanding the nature of biological relationships. The passage describes how trillions of microorganisms interact with the human body, particularly emphasizing their active role in health maintenance.
The correct answer is C because the passage explicitly states that the microbiome "engages in a symbiotic relationship with its host that is crucial for health." The text provides clear evidence of mutual benefits: microorganisms help digest complex carbohydrates, produce essential vitamins, and support immune system function, while they receive nutrients and habitat from the human host. This cooperation benefits both parties, defining a true symbiotic relationship.
Answer A incorrectly suggests parasitism, where only microorganisms would benefit while harming the host. However, the passage emphasizes how microbes provide essential services like vitamin production and immune training. Answer B mischaracterizes the relationship as purely competitive, ignoring the passage's emphasis on cooperation and the microbiome's role in "training and modulating" rather than battling the immune system. Answer D contradicts the passage's central theme by suggesting microbes are "passive inhabitants with little effect," when the text clearly states they are "not merely passive" and actively contribute to digestion, vitamin production, and immune function.
Remember that HESI questions about biological relationships often test whether you can distinguish between different types of interactions (symbiotic, parasitic, competitive, neutral). Focus on identifying evidence of mutual benefit versus harm when analyzing host-microorganism relationships.
- Which of the following statements best summarizes the main idea of the passage?
Answer: The microbiome is a complex internal ecosystem that is essential for various aspects of human health, including digestion, immunity, and mental well-being, but it is vulnerable to disruption.
When you encounter reading comprehension questions asking for the "main idea," you need to identify the central theme that encompasses all the key points discussed, not just focus on specific details or examples.
This passage presents the microbiome as a complex, beneficial ecosystem that performs multiple essential functions but is also fragile. The author systematically covers three main aspects: the microbiome's beneficial roles (digestion, vitamin production, immune system support), emerging discoveries (gut-brain connection), and vulnerability to disruption (diet, stress, antibiotics leading to dysbiosis and disease). Answer choice B captures all these elements by emphasizing the microbiome's complexity, its essential role across multiple health domains, and its susceptibility to disruption.
Answer choice A is too narrow because it focuses primarily on antibiotic disruption and chronic diseases, missing the broader discussion of beneficial functions and multiple disruptive factors. Answer choice C incorrectly elevates the gut-brain axis as the "most important discovery" and makes an unsupported claim about direct control of mental health, when the passage only suggests a communication relationship. Answer choice D severely understates the microbiome's importance by limiting it to just digestion and vitamin production, completely ignoring the immune system effects, mental health connections, and vulnerability issues.
For HESI reading questions, remember that main idea answers should be comprehensive without being too broad or too narrow. Look for choices that capture the passage's full scope while avoiding extreme language or unsupported claims that go beyond what the author actually states.
- According to the passage, what is the most significant implication of the universal precautions approach to health literacy?
Answer: It acknowledges that health literacy challenges are widespread enough to warrant clear communication practices for all patients rather than targeting specific populations.
When you encounter questions about health literacy approaches, focus on understanding the underlying philosophy and practical implications of different strategies rather than getting caught up in implementation details.
The universal precautions approach to health literacy operates on a simple but powerful principle: since health literacy challenges are so widespread (affecting 36% of adults according to the passage), it's more effective to use clear communication practices with everyone rather than trying to identify and single out patients with limited literacy. This approach recognizes that health information can be complex for anyone, regardless of education level, especially during stressful medical situations.
Choice A correctly captures this core concept—the approach acknowledges the widespread nature of health literacy challenges and responds by implementing clear communication universally. Choice B misrepresents the approach by suggesting it eliminates individual assessment entirely, when in reality it simply establishes a baseline of clear communication while still allowing for personalized care. Choice C incorrectly focuses on cost and technology requirements, which aren't mentioned as defining features of this approach in the passage. Choice D distorts the concept by suggesting it assumes patient incapability rather than recognizing that clear communication benefits everyone.
The key insight is that universal precautions isn't about "dumbing down" information—it's about making communication accessible without stigmatizing anyone. Remember that HESI questions about health literacy often test whether you understand patient-centered approaches that maintain dignity while improving comprehension. Look for answer choices that emphasize inclusive, respectful strategies rather than those that segregate or oversimplify patient care.
- Which statement best summarizes the concept of sleep hygiene as described in the passage?
Answer: It is a collection of habits and environmental adjustments that reinforce the body's natural sleep-wake cycle.
When you encounter reading comprehension questions about health concepts, focus on identifying the main idea and distinguishing it from specific details or common misconceptions.
The passage clearly defines sleep hygiene as "behavioral and environmental practices that are intended to promote better quality sleep" and emphasizes how these practices "work in concert to reinforce natural sleep patterns." The key insight is that sleep hygiene involves multiple coordinated strategies—consistent sleep schedules, optimal environment, pre-sleep rituals, and avoiding stimulants—all designed to support your body's circadian rhythm.
Answer C correctly captures this comprehensive approach by describing sleep hygiene as "a collection of habits and environmental adjustments that reinforce the body's natural sleep-wake cycle." This aligns perfectly with the passage's emphasis on supporting natural sleep patterns through various coordinated practices.
Answer A misinterprets the term "hygiene" literally. The passage explicitly states sleep hygiene "is not about cleanliness" but rather about behavioral practices.
Answer B incorrectly characterizes sleep hygiene as a "strict medical regimen" for "severe sleep disorders." The passage presents it as general wellness practices anyone can implement, not medical treatment.
Answer D focuses too narrowly on just one component—avoiding electronic devices. While the passage mentions blue light from screens, this is only one element among many practices that constitute sleep hygiene.
Study tip: On HESI reading questions, watch for answers that are either too narrow (focusing on one detail) or based on literal interpretations of terms when the passage provides a different definition.
