What does acute confusion in an older hospitalized adult suggest until proven otherwise? -
(ANSWER)Delirium.
What is delirium? - (ANSWER)An acute, fluctuating change in attention, awareness, and cognition usually
caused by an underlying medical problem.
What is the onset of delirium? - (ANSWER)Sudden; hours to days.
What is the course of delirium? - (ANSWER)Fluctuating; often worse at night.
What is the priority nursing action for delirium? - (ANSWER)Identify and treat the underlying cause.
What are common causes of delirium in older adults? - (ANSWER)Infection, hypoxia, pain, constipation,
dehydration, urinary catheter, electrolyte imbalance, alcohol withdrawal, and medication toxicity.
What sensory aids help prevent delirium? - (ANSWER)Glasses, hearing aids, dentures, clocks, calendars,
and familiar items.
Why should unnecessary urinary catheters be avoided in older adults? - (ANSWER)They increase
infection risk and can contribute to delirium and immobility.
What medications can increase delirium risk? - (ANSWER)Sedatives, anticholinergics, some sleep aids,
opioids, benzodiazepines, and other CNS-altering medications.
What is dementia? - (ANSWER)A chronic, progressive decline in cognition and function.
What is the onset of dementia? - (ANSWER)Gradual.
What is a key early sign of dementia? - (ANSWER)Short-term memory impairment.

What is a key communication strategy for dementia? - (ANSWER)Use short, simple statements and allow
extra time for responses.
Should nurses argue with or correct false beliefs in dementia? - (ANSWER)No; validate feelings and
redirect instead.
What is a priority in dementia care? - (ANSWER)Maintain safety while preserving dignity and autonomy.
What should the nurse assess when a patient with dementia becomes agitated? - (ANSWER)Unmet
needs such as pain, hunger, thirst, toileting, fatigue, fear, or overstimulation.
Is depression a normal part of aging? - (ANSWER)No; depression is not expected aging.
What must nurses assess in older adults with depression? - (ANSWER)Suicidal ideation and safety risk.
What interventions help older adults with depression? - (ANSWER)Therapeutic communication, social
interaction, routine, sleep hygiene, daytime exercise, CBT referral, and purpose-building activities.
What aging skin changes increase injury risk? - (ANSWER)Thinner skin, decreased collagen, decreased
subcutaneous fat, and decreased elasticity.
What aging vision changes increase fall risk? - (ANSWER)Decreased visual acuity, smaller pupils, impaired
color vision, and need for more light.
What aging hearing change is common? - (ANSWER)Difficulty hearing high-pitched sounds.
What cardiovascular changes occur with aging? - (ANSWER)Decreased cardiac output, stiffer valves,
thicker cardiac walls, and decreased coronary blood flow.

What GI changes occur with aging? - (ANSWER)Decreased motility, slower digestion, taste changes, and
decreased liver capacity.
What renal changes occur with aging? - (ANSWER)Decreased GFR, decreased renal blood flow, smaller
kidneys, and incomplete bladder emptying.
Why are older adults at higher medication toxicity risk? - (ANSWER)Renal and hepatic clearance
decrease with aging.
What musculoskeletal changes occur with aging? - (ANSWER)Decreased bone density, decreased muscle
mass, decreased height, spinal curvature, and impaired balance.
What respiratory changes occur with aging? - (ANSWER)Decreased ventilation, decreased lung elasticity,
and reduced tolerance for low oxygen states.
What immune changes occur with aging? - (ANSWER)Reduced lymphocyte function and decreased
immune surveillance.
What is the #1 cause of injury and injury-related death in adults 65+? - (ANSWER)Falls.
What should fall prevention include for older adults? - (ANSWER)Assess mobility, remove hazards,
ensure sensory aids, review medications, use assistive devices, and encourage safe activity.
What is anemia? - (ANSWER)A decrease in RBCs, hemoglobin, or hematocrit that reduces oxygen-
carrying capacity.
What are the three broad types of anemia from the lecture? - (ANSWER)Hypoproliferative, blood loss,
and hemolytic anemia.
