Guide to Geriatric Nursing: Common Challenges

Geriatric Nursing: Managing Complexity

Geriatric Nursing requires navigating the intersection of multiple chronic conditions, physiological decline, and psychosocial vulnerability. Unlike younger populations where the goal is often cure, geriatric care frequently prioritizes function, comfort, and quality of life. The presentation of illness in older adults is often atypical; for example, a urinary tract infection may manifest as confusion rather than fever. This guide outlines the core challenges in caring for the elderly, from medication safety to cognitive assessment, providing a framework for robust clinical practice.

The American Geriatrics Society (AGS) highlights that by 2030, older adults will account for 20% of the US population. Nurses must be proficient in the “Geriatric Giants”: Immobility, Instability, Incontinence, and Intellectual Impairment.

Polypharmacy and Medication Safety

Polypharmacy is the concurrent use of multiple medications. In the elderly, this creates a high risk for adverse drug events due to altered pharmacokinetics (reduced renal/hepatic clearance).

• The Prescribing Cascade: Treating the side effect of one drug with another drug (e.g., adding a diuretic for amlodipine-induced edema).
• Beers Criteria: A list of medications potentially inappropriate for older adults (e.g., Benzodiazepines, Anticholinergics) due to fall and delirium risk.
• Nursing Action: Perform medication reconciliation at every transition. Advocate for deprescribing unnecessary agents.

Falls and Mobility

Falls are the leading cause of fatal and non-fatal injuries in older adults. They are not a normal part of aging but a symptom of underlying frailty.

• Risk Factors: Orthostatic hypotension, sensory deficits (vision/hearing), muscle weakness (sarcopenia), and environmental hazards.
• Intervention: Implement fall precautions (bed alarms, non-slip socks). Encourage resistance training to improve balance. Review medications that cause dizziness.

Functional Assessment: ADLs vs. IADLs

Measuring independence is key to care planning. Nurses use specific tools to quantify functional status.

• Activities of Daily Living (ADLs): Basic self-care tasks (bathing, dressing, toileting, transferring, continence, feeding). Assessed using the Katz Index of Independence.
• Instrumental Activities of Daily Living (IADLs): Complex skills needed for independent living (managing finances, shopping, cooking, taking medications, using the telephone). Assessed using the Lawton Scale.

Cognitive Impairment: The 3 D’s

Distinguishing between Delirium, Dementia, and Depression is a critical nursing skill.

Delirium

Onset: Acute (hours to days).
Cause: Infection (UTI/Pneumonia), dehydration, medication toxicity.
Reversibility: Usually reversible if the underlying cause is treated.
Symptoms: Fluctuating attention, hallucinations, altered consciousness.

Dementia

Onset: Chronic and progressive (months to years).
Cause: Alzheimer’s, Vascular changes, Lewy Body.
Reversibility: Generally irreversible.
Symptoms: Memory loss, executive dysfunction, personality changes.

Depression

Onset: Variable, often coincides with life changes (loss).
Symptoms: Apathy, weight loss, sleep disturbance. Often mistaken for dementia (“Pseudodementia”).

Nutritional and Hydration Challenges

Malnutrition and dehydration are prevalent but often overlooked.

• Sarcopenia: Age-related loss of muscle mass. Adequate protein intake (1.2g/kg) is vital unless contraindicated by renal disease.
• Dehydration: Thirst drive diminishes with age. Monitor for orthostasis and acute kidney injury.
• Dysphagia: Swallowing difficulties increase aspiration risk. Screen all stroke and dementia patients.
• Assessment Tool: The Mini Nutritional Assessment (MNA) identifies those at risk of malnutrition.

Atypical Presentation of Illness

Physiological reserve decreases with age, altering the body’s response to stress.
Infection: May present without fever or leukocytosis. Look for confusion, falls, or anorexia.
Myocardial Infarction: “Silent” MI is common. Look for dyspnea, confusion, or fatigue rather than crushing chest pain.

Elder Mistreatment Screening

Vulnerable older adults are at risk for abuse, neglect, and exploitation.

• Physical/Sexual Abuse: Unexplained bruises, fractures, or infections.
• Neglect: Poor hygiene, dehydration, untreated bedsores.
• Financial Exploitation: Sudden changes in wills or bank accounts.
• Nursing Role: Nurses are mandatory reporters. Suspicions must be reported to Adult Protective Services (APS), regardless of proof.

Palliative Care Integration

Palliative care focuses on symptom management and quality of life for those with serious illness. It is appropriate at any age and any stage, not just end-of-life.
Advance Care Planning: Nurses play a key role in discussing code status (DNR/DNI) and goals of care before a crisis occurs.

Skin Integrity and Pressure Injuries

Aging skin is thinner, less elastic, and has reduced blood supply.
Risk: Immobility and incontinence increase the risk of pressure ulcers (decubitus ulcers).
Prevention: Reposition q2h, ensure adequate protein intake, and manage moisture.

Conclusion

Geriatric nursing is a specialized field requiring keen observational skills. By recognizing atypical presentations, managing polypharmacy, and distinguishing delirium from dementia, nurses preserve dignity and independence in older adults.
