Gerontology questions hinge on one principle: confusion is never normal aging. Work through these 10 practice questions on delirium versus dementia versus depression, the Beers criteria, normal aging changes, falls, and elder abuse, each with a full rationale.
Older Adult Care: The 3 D's, Beers Criteria & Normal Aging
The single most tested principle in older-adult care is that confusion is NOT a normal part of aging. New-onset acute confusion is delirium until proven otherwise, and delirium is a medical emergency: it is acute and sudden in onset, fluctuates, alters attention and level of consciousness, and is usually reversible once you find and fix the cause (infection such as a UTI, medications, hypoxia, dehydration, electrolyte imbalance, or uncontrolled pain). Contrast this with dementia, which is gradual, progressive, chronic, and generally irreversible, and with depression (pseudodementia), which is mood-related and can mimic dementia. Remember too that older adults present atypically: a serious infection may show up as new confusion, a fall, or a decline in function rather than a fever.
Know the difference between normal age-related changes and pathology. Expected changes include thinner skin with decreased turgor, reduced renal and hepatic clearance (so drugs need dose adjustment and clear more slowly), decreased thirst sensation (dehydration risk), presbyopia, presbycusis with high-frequency hearing loss, slowed reaction time, reduced immune response, decreased gastric motility, and bone-density loss. Because of altered pharmacokinetics, older adults are highly medication-sensitive: apply the Beers Criteria and start low, go slow. High-risk potentially inappropriate drugs include benzodiazepines, anticholinergics, first-generation antihistamines like diphenhydramine, and chronic NSAIDs, which raise the risk of falls, confusion, and bleeding.
Round out your review with safety and function. Falls are the leading cause of injury in older adults, so assess risk and prevent it (low bed, lighting, clear path, mobility aids). Recognize elder abuse and neglect and remember nurses are mandated reporters. Assess ADLs and IADLs (Katz/Lawton) to promote maximal independence. Adapt communication for sensory loss: face the client, ensure good lighting, minimize background noise, use lower-pitched tones, and allow extra time. Promote health with age-appropriate immunizations (influenza, pneumococcal, zoster/shingles, RSV) and immobility/pressure-injury prevention.
Gerontology & Older Adult NCLEX Practice Questions
Question 1 · The Three D's / Delirium
An 82-year-old woman who was alert and oriented at baseline is brought to the emergency department by her daughter, who reports that over the past two days her mother has become confused, is picking at the bed linens, and is drowsy one moment and agitated the next. Her temperature is 99.0 F (37.2 C). Which interpretation should guide the nurse's next actions?
- A This is an expected change of aging, and the nurse should simply reorient the client and reassure the family
- B This most likely represents delirium, and the nurse should assess for an underlying cause such as infection
- C This indicates dementia, and the nurse should discuss long-term memory-care placement with the daughter
- D This is depression, and the nurse should request a psychiatric consult before any further workup
Show answer & rationale
Correct answer: B
Acute, fluctuating confusion with altered attention and level of consciousness that develops over hours to days is the classic picture of delirium, which is a medical emergency. The nurse should treat it as delirium until proven otherwise and look for a reversible cause; in older adults a urinary tract infection is one of the most common triggers, along with medications, hypoxia, dehydration, electrolyte imbalance, and pain. Note the atypical presentation: this client has only a low-grade temperature, yet older adults frequently show infection as new confusion, falls, or functional decline rather than a high fever. Calling this an expected change of aging is wrong and dangerous, because confusion is never a normal part of aging and reorientation alone would miss a treatable, potentially life-threatening cause. Labeling it dementia is incorrect because dementia has a gradual, progressive, chronic course over months to years, not a sudden onset with fluctuating consciousness; jumping to placement is premature. Depression (pseudodementia) is mood-related and can mimic cognitive decline, but it does not typically cause this acute fluctuating attention/consciousness picture, and a psychiatric consult would delay urgent medical evaluation. Clinical pearl: remember that delirium is Acute, Attention-impaired, and often reversible, whereas dementia is a slow Decline. New acute confusion in an older adult means rule out infection first.
Question 2 · Delirium vs Dementia (SATA)
A nurse is comparing delirium and dementia during a staff education session. Which findings are characteristic of delirium rather than dementia? Select all that apply.
- A Gradual, progressive decline in memory over months to years
- B Frequently triggered by infection, medications, dehydration, or hypoxia
- C Acute, sudden onset over hours to days
- D Impaired ability to sustain or shift attention
- E Fluctuating level of consciousness and attention
- F Often reversible once the underlying cause is treated
Show answer & rationale
Correct answer: B, C, D, E, F
Delirium is defined by an acute, sudden onset over hours to days, so that finding is correct. It characteristically produces a fluctuating level of consciousness and attention, waxing and waning through the day, which is also correct. Delirium is usually reversible when the precipitant is identified and treated, distinguishing it from the generally irreversible course of dementia, so that option belongs. It is frequently triggered by infection (classically a UTI in older adults), medications, dehydration, electrolyte imbalance, hypoxia, and pain, so that option is correct. Impaired attention, the inability to sustain or shift focus, is a core diagnostic feature of delirium and is included. The one option that does not fit delirium is gradual, progressive decline in memory over months to years, which describes dementia, a chronic and generally irreversible process; that is why it is excluded. Clinical pearl: think of delirium as a smoke alarm, an urgent signal that something acute (often infection) is wrong and can be fixed, whereas dementia is a slow structural decline. When an older adult with known dementia suddenly gets acutely worse, suspect superimposed delirium and search for a cause rather than attributing the change to their baseline dementia. Attention is the single best bedside discriminator: delirious clients cannot hold attention, while early-dementia clients often can.
Question 3 · Normal Aging vs Pathology
During a wellness visit, a 74-year-old man asks the nurse which changes are a normal, expected part of getting older. Which finding should the nurse identify as an expected age-related change rather than a sign of disease?
- A New-onset confusion and disorientation
- B Chest pressure that occurs with exertion
- C Loss of bladder control (urinary incontinence)
- D Reduced high-frequency hearing (presbycusis)
Show answer & rationale
Correct answer: D
Presbycusis, a gradual, symmetric loss of high-frequency hearing, is a normal age-related change caused by degeneration of cochlear hair cells; identifying it as expected is correct. This is why older adults often struggle to hear consonants and high-pitched voices and do better with lower-pitched speech. New-onset confusion and disorientation is not a normal part of aging and should prompt evaluation for delirium (often infection) or other pathology, so it is incorrect to call it expected. Chest pressure with exertion suggests angina and possible coronary artery disease; it is a pathologic symptom requiring assessment, never a normal aging change. Urinary incontinence is common in older adults but is not normal; it is a treatable condition with many causes (infection, medications, prolapse, overactive bladder, mobility limits) and should be assessed rather than dismissed as aging. Clinical pearl: keep a clear mental list of what truly is normal aging, thinner skin with decreased turgor, presbyopia and presbycusis, reduced renal and hepatic clearance, decreased thirst, slowed reaction time, reduced immune response, decreased gastric motility, and bone-density loss, and treat everything else (confusion, chest pain, incontinence, falls) as a symptom to investigate. Normalizing pathology delays care; over-medicalizing normal aging causes needless worry. Knowing the boundary is high-yield on the NCLEX.
Question 4 · Normal Aging Changes (SATA)
A nurse is teaching a group of older adults about expected physiologic changes of aging. Which changes should the nurse describe as normal and expected? Select all that apply.
- A Decreased sensation of thirst, increasing dehydration risk
- B Confusion and memory loss severe enough to interfere with daily life
- C Slowed reaction time
- D Thinner skin with decreased skin turgor
- E Reduced renal and hepatic function that slows drug clearance
- F Presbyopia (difficulty focusing on near objects)
Show answer & rationale
Correct answer: A, C, D, E, F
Thinner skin with decreased turgor is a normal age-related change due to loss of dermal elasticity and subcutaneous tissue, so it is correct (and it also means skin turgor is a less reliable hydration marker in older adults). Reduced renal and hepatic function is expected with aging and slows drug clearance, which is exactly why medications often need lower doses and longer intervals, start low and go slow, so that option belongs. Decreased thirst sensation is a normal change that raises dehydration risk, making it correct and clinically important for teaching fluid intake. Presbyopia, the age-related decline in near focusing from a stiffer lens, is normal and included. Slowed reaction time is an expected neurologic change and is correct; it contributes to fall risk and driving concerns but is not disease. The option that must be excluded is confusion and memory loss severe enough to interfere with daily life: cognition-impairing confusion is never normal aging. Mild slowing of processing speed can occur, but functional confusion signals delirium, dementia, or another disorder and requires evaluation. Clinical pearl: nearly every organ system slows with age, but the brain's core function, clear thinking, should stay intact. When you see confusion in an older-adult stem, do not accept it as aging; look for a cause.
Question 5 · Beers Criteria / Polypharmacy
A nurse is reviewing the medication list of a 78-year-old woman who reports two recent falls and daytime grogginess. Which medication on her list should the nurse flag as potentially inappropriate for an older adult according to the Beers Criteria?
- A Acetaminophen for osteoarthritis pain
- B Lisinopril for hypertension
- C Diphenhydramine taken nightly for sleep
- D Vitamin D supplement for bone health
Show answer & rationale
Correct answer: C
Diphenhydramine is a first-generation antihistamine with strong anticholinergic and sedating effects and is a classic Beers Criteria potentially inappropriate medication for older adults; flagging it is correct. Its anticholinergic burden and sedation raise the risk of confusion, urinary retention, dry mouth, blurred vision, and, critically for this client, falls and daytime grogginess. It is best avoided for sleep in older adults, who are more sensitive to these effects because of reduced clearance and a more permeable blood-brain barrier. Acetaminophen is actually the preferred first-line analgesic for osteoarthritis in older adults because it avoids NSAID-related bleeding and renal risks, so it is not the drug to flag. Lisinopril is an appropriate, guideline-supported antihypertensive and is not a Beers concern at usual dosing. Vitamin D is commonly prescribed for older adults to support bone health; unlike the anticholinergic, it is not a potentially inappropriate medication on the Beers list. Clinical pearl: memorize the high-risk Beers categories that cause falls, confusion, and bleeding, benzodiazepines, anticholinergics (including oxybutynin and many OTC sleep and cold aids), first-generation antihistamines like diphenhydramine, and chronic NSAIDs. When a stem pairs an older adult with new falls, sedation, or confusion, scan the med list first; a recently added anticholinergic or sedative is frequently the culprit, and deprescribing is the intervention.
Question 6 · Beers / Polypharmacy (SATA)
A nurse is performing medication reconciliation for an 80-year-old client. Which medications should the nurse recognize as high-risk in older adults because they increase the risk of falls, confusion, or bleeding? Select all that apply.
- A Acetaminophen
- B Oxybutynin
- C Lisinopril
- D Lorazepam
- E Chronic daily ibuprofen
- F Diphenhydramine
Show answer & rationale
Correct answer: B, D, E, F
Lorazepam is a benzodiazepine; benzodiazepines are Beers-flagged in older adults because they cause sedation, cognitive impairment, and falls, and older adults metabolize them more slowly, so it is correct. Diphenhydramine is a first-generation, highly anticholinergic antihistamine that causes confusion, sedation, and fall risk and should generally be avoided, so it belongs. Chronic daily ibuprofen is a long-term NSAID, which raises the risk of GI bleeding, acute kidney injury, and fluid retention/heart failure in older adults, making it high-risk and correct. Oxybutynin is a strongly anticholinergic bladder antispasmodic that adds to confusion, constipation, urinary retention, and fall risk, so it is included. Acetaminophen is excluded because it is the preferred, safer analgesic for older adults and does not carry these fall/confusion/bleeding risks at recommended doses. Lisinopril is excluded because an ACE inhibitor for hypertension is appropriate and not a Beers-based fall/confusion/bleeding hazard at usual dosing (though the nurse still monitors for orthostasis and potassium). Clinical pearl: anticholinergic burden is cumulative, several mild anticholinergics together (a sleep aid, a bladder drug, an antihistamine) can push an older adult into delirium and falls. Reconcile every med, count the anticholinergic and sedative load, and advocate to deprescribe. Start low, go slow, and question every new symptom as a possible drug effect.
Question 7 · Falls Prevention
A nurse is planning care to reduce fall risk for a 79-year-old hospitalized client who needs to use the bathroom frequently at night. Which intervention is the most appropriate and safest fall-prevention measure?
- A Keep the bed in the low position with a clear, well-lit path to the bathroom
- B Keep all four side rails up at all times to keep the client in bed
- C Apply a vest restraint at night so the client cannot get up unassisted
- D Place the client on strict bed rest to eliminate the chance of falling
Show answer & rationale
Correct answer: A
Keeping the bed in the low position with a clear, well-lit, uncluttered path to the bathroom directly targets the leading causes of falls, environmental hazards, poor lighting, and a long or obstructed route, and is the correct, least-restrictive intervention. Adding a call light within reach, nonskid footwear, and toileting rounds further reduces risk. Raising all four side rails is considered a restraint; it can prompt the client to climb over the rail, causing a fall from a greater height with more serious injury, so it is unsafe. A vest restraint is also a restraint and paradoxically increases risk of injury, agitation, delirium, deconditioning, and even death; restraints are a last resort and do not prevent falls. Strict bed rest causes immobility harms, deconditioning, pressure injuries, venous thromboembolism, and worsened deconditioning that increases fall risk over time, so it is inappropriate and not least-restrictive. Clinical pearl: falls are the leading cause of injury in older adults, and the best strategy is proactive, least-restrictive prevention, low bed, call light in reach, adequate lighting, mobility aids nearby, scheduled toileting, and reviewing high-risk (Beers) medications, rather than physically confining the client. Meeting the client's needs (like toileting) prevents more falls than restricting movement ever will.
Question 8 · Elder Abuse
A home-health nurse notices that a 76-year-old client has multiple bruises in various stages of healing. The client is thin, appears fearful, and the caregiver answers all questions on the client's behalf and refuses to leave the room. What is the nurse's most appropriate action?
- A Document the findings and reassess at the next scheduled visit
- B Privately confront the caregiver about the suspicious bruising
- C Report the suspected elder abuse per state reporting laws
- D Advise the client to move out of the home immediately
Show answer & rationale
Correct answer: C
The cluster of findings, bruises in various stages of healing, apparent malnutrition, fearfulness, and a controlling caregiver who answers for the client and blocks private conversation, are classic red flags for elder abuse and neglect. Nurses are mandated reporters, so reporting the suspicion through the appropriate channel (such as Adult Protective Services per state law) is the correct action; the nurse does not need to prove abuse, only to have a reasonable suspicion. Documenting and waiting until the next visit is unsafe because it leaves the client in a potentially dangerous situation and delays protection. Confronting the caregiver is inappropriate and can escalate the risk to the client and compromise any investigation; safe assessment includes trying to interview the client alone, but confrontation is not the nurse's role. Telling the client to move out immediately is not realistic, may not be possible or safe, and oversteps the client's autonomy and the appropriate investigative process. Clinical pearl: you are a mandated reporter, when in doubt, report. Also try to assess the older adult privately, because a caregiver who insists on answering for a competent client and prevents alone-time is itself a warning sign. Objective, factual documentation (photographs per policy, exact wording, body-map of injuries) supports the report and protects the client.
Question 9 · Sensory / Communication Adaptation
A nurse is preparing to give discharge teaching to an older adult who has presbycusis. Which communication technique will best help the client understand the instructions?
- A Face the client and speak slowly in a lower-pitched voice
- B Stand behind the client and speak directly into the better ear
- C Communicate only through written notes to avoid confusion
- D Speak in a higher-pitched, louder voice from across the room
Show answer & rationale
Correct answer: A
Presbycusis causes loss of high-frequency hearing, so older adults hear low-pitched sounds better than high-pitched ones. Facing the client (which allows lip-reading and use of visual cues) and speaking slowly in a lower-pitched, clear voice is the correct, evidence-based approach; reducing background noise, good lighting, and allowing extra time further improve comprehension. Speaking in a higher-pitched, louder voice is counterproductive because raising the pitch moves the voice into the exact frequency range the client cannot hear, and shouting distorts speech and words; volume alone from across the room does not help. Standing behind the client removes visual cues and lip-reading and prevents the client from knowing they are being addressed, so it worsens communication. Communicating only through written notes wrongly assumes the client cannot hear at all, may not match the client's literacy or vision, and is not the best first-line technique for presbycusis; verbal communication with sensory adaptations plus supportive written material is preferred. Clinical pearl: for presbycusis, lower the pitch, do not just raise the volume; face the client in good light; cut background noise; and confirm understanding with teach-back. Ensure any hearing aids are in place and working. Small environmental and technique changes dramatically improve safety and adherence for hearing-impaired older adults.
Question 10 · Functional Assessment (ADLs/IADLs)
A nurse is assessing an older adult's functional status and wants to document an instrumental activity of daily living (IADL). Which activity should the nurse document as an IADL?
- A Eating a meal independently
- B Transferring from the bed to a chair
- C Grooming and combing hair
- D Managing medications and finances
Show answer & rationale
Correct answer: D
Instrumental activities of daily living (IADLs), assessed with tools such as the Lawton scale, are the more complex tasks needed to live independently in the community, including managing medications, handling finances, shopping, meal preparation, housekeeping, using transportation, and using the telephone. Managing medications and finances is therefore correctly classified as an IADL. Eating, transferring from bed to chair, and grooming are basic activities of daily living (ADLs), the fundamental self-care tasks captured by the Katz index (bathing, dressing, toileting, transferring, continence, and feeding). These are not IADLs, so they are incorrect choices here. Distinguishing the two matters clinically: IADLs typically decline before basic ADLs, so a new inability to manage medications or money can be an early sign of cognitive decline or functional loss and should prompt further assessment, including safety planning. Clinical pearl: remember ADLs are survival self-care (feed, bathe, dress, toilet, transfer, continence), while IADLs are independence tasks (shopping, housekeeping, accounting/finances, food prep, transportation, and telephone/technology, plus medication management). Assessing both guides the level of support a client needs, informs discharge planning and referrals (home health, meal services), and helps the nurse promote maximal independence and safety rather than doing too much for the client.

Gerontology & Older Adult FAQ
How do I tell the difference between delirium and dementia on the NCLEX?
Focus on onset and course. Delirium is acute and sudden (hours to days), fluctuates, impairs attention and level of consciousness, and is usually reversible once you treat the cause, common causes are infection (especially UTI), medications, dehydration, hypoxia, electrolyte imbalance, and pain. Dementia is gradual, progressive, chronic, and generally irreversible, with slowly declining memory over months to years. On the exam, treat any new acute confusion in an older adult as delirium and a medical emergency: look for a cause first. The best bedside clue is attention, delirious clients cannot sustain attention, while early-dementia clients often can.
Is confusion a normal part of aging?
No. This is one of the most important teaching points in gerontology. Cognition-impairing confusion is never a normal age-related change. Normal aging includes thinner skin, presbyopia and presbycusis (high-frequency hearing loss), reduced renal and hepatic clearance, decreased thirst, slowed reaction time, reduced immune response, decreased gastric motility, and bone-density loss, but clear thinking should remain intact. New confusion signals a problem such as delirium (often infection), medication effects, dehydration, or dementia and always requires evaluation rather than being dismissed as aging.
What are the Beers Criteria and which drugs are high-risk in older adults?
The Beers Criteria is a list of potentially inappropriate medications for older adults. High-risk categories that increase falls, confusion, and bleeding include benzodiazepines (like lorazepam), anticholinergics (like oxybutynin), first-generation antihistamines (like diphenhydramine, often in OTC sleep and cold aids), and chronic NSAIDs (like daily ibuprofen). Older adults are more sensitive because of reduced drug clearance, so the rule is start low and go slow, reconcile medications at every visit, and watch for cumulative anticholinergic burden. When an older adult has new falls, sedation, or confusion, review the medication list first.
Why do older adults with a serious infection sometimes not have a fever?
Older adults often present atypically. Because of reduced immune response and a blunted fever response, a serious infection may show up as new confusion (delirium), a fall, decreased appetite, or a drop in functional ability instead of a high temperature. A urinary tract infection classically causes sudden confusion in an older adult. On the NCLEX, do not wait for a fever to suspect infection, treat new confusion, falls, or functional decline as possible signs of a serious underlying problem and assess for a cause.
