Aging Process and Human Development

Aging on the Excel Testing Human Needs Outline

New Hampshire's LNA competency knowledge test, administered by Excel Testing, includes Human Needs content that covers the aging process. LNAs care for older adults daily in nursing homes, assisted living, hospitals, and home health. Exam success—and safe practice—depends on one clinical judgment skill: separating normal aging from abnormal change that signals disease.

Normal aging is gradual and expected. Disease is new, sudden, progressive beyond baseline, or functionally disabling. Treating normal aging as illness leads to over-medicalizing residents. Treating illness as "just old age" delays life-saving care. Your role is to observe carefully, adapt care for expected changes, and report unexpected changes to the nurse.

Normal vs Abnormal Aging

Examples of normal aging

• Gradual decrease in near vision (presbyopia) and need for brighter light
• Mild high-frequency hearing loss
• Thinner, drier, more fragile skin with slower healing
• Decreased muscle mass and joint flexibility; slower gait
• Slightly lower maximum heart rate and less efficient circulation with activity
• Occasional forgetfulness of names or where items were placed, with intact orientation

Examples that are NOT normal aging

• Sudden confusion, delirium, or a new inability to recognize familiar people
• New urinary or fecal incontinence without a known chronic pattern
• Unexplained weight loss, fever, or night sweats
• New chest pain, sudden one-sided weakness, or slurred speech
• Severe depression with withdrawal from all usual activities
• A pressure injury, new bruise pattern, or unexplained skin breakdown

If you are unsure whether a change is normal, report it. LNAs do not diagnose, but they are the nurse's primary early-warning system.

Sensory Changes

Aging often dulls vision, hearing, taste, and smell. Care adaptations matter more than "talking louder at everyone":

• Vision: Provide adequate lighting, reduce glare, keep pathways clear, and announce yourself. Place call lights, water, and personal items within the visual field the resident actually uses.
• Hearing: Face the resident, speak clearly at a moderate pace, reduce background TV noise, and rephrase rather than shout. Confirm understanding of care instructions.
• Taste and smell: Appetite may fall; offer preferred foods within diet orders, report refusal patterns, and watch for unnoticed spoiled food if smell is impaired.
• Touch: Some older adults feel temperature extremes less accurately—always check bath water yourself and use facility temperature guidelines.

Never assume sensory loss equals cognitive impairment. A resident who does not answer may simply not have heard you.

Skin Changes

Aging skin has less fat, oil, and elasticity. Capillaries are fragile, so bruising occurs easily. Implications for LNA care:

• Handle gently during transfers; avoid dragging across sheets.
• Keep skin clean and dry; moisturize per care plan; report redness over bony prominences immediately.
• Reposition bedbound residents on the schedule in the care plan (commonly at least every two hours unless ordered otherwise).
• Protect from tape trauma and friction; report new tears, rashes, or open areas the same shift.

Thin skin is a normal aging change. A stageable pressure injury is not—report it as a clinical finding, not as an inevitable consequence of age.

Musculoskeletal Changes

Muscle mass and bone density decline with age (sarcopenia and osteopenia/osteoporosis risk). Joints stiffen and balance reactions slow. LNAs support function by:

• Encouraging safe mobility and resting as needed without forcing marathon walks
• Using gait belts and assistive devices listed on the care plan
• Performing range-of-motion exercises only as trained and assigned
• Allowing extra time for dressing and transfers to protect dignity and prevent falls
• Reporting new weakness, inability to bear weight, or sudden joint deformity after a fall

Slower movement can be normal. Acute inability to walk that was present yesterday is not.

Cardiovascular and Circulation Changes

The aging heart and vessels are less elastic. Blood pressure patterns may change, orthostatic hypotension becomes more common, and extremities may cool more easily. LNA implications:

• Rise residents slowly from lying to sitting to standing; pause and ask about dizziness.
• Report edema, sudden shortness of breath, chest pain, cyanosis, or cold mottled limbs.
• Support activity tolerance without pushing past care-plan limits.
• Keep residents warm with appropriate clothing and blankets while watching for overheating.

Fatigue after activity can be expected. Crushing chest pain or sudden dyspnea at rest is an emergency report.

Psychosocial Development in Later Life

Human development continues into older adulthood. Erikson's later-life theme of integrity versus despair appears on many nursing-assistant curricula: residents review their lives and seek meaning, or they struggle with regret and isolation. Common psychosocial stressors include retirement, loss of spouse or friends, role changes, relocation to a facility, and declining independence.

Supportive LNA actions:

• Use the resident's preferred name and honor routines that preserve identity.
• Encourage participation in activities the resident values.
• Listen without dismissing grief as unimportant.
• Protect privacy during emotional conversations.
• Report statements of hopelessness, self-harm, or sudden personality change to the nurse.

Loneliness can accompany aging. Clinical depression and suicidal ideation do not equal normal aging and must be escalated.

Do Not Treat Normal Aging as Disease

A high-yield exam trap is the option that medicalizes an expected change—for example, insisting every older adult with dry skin has a serious disease, or conversely claiming sudden confusion is "normal for old people." Correct thinking:

Age with respect. Adapt care for expected changes. Escalate unexpected changes. That triad is what Excel Testing's aging-process items are built to measure.
