Chronic Conditions Common in Older Adults: Cardiovascular, Respiratory, and Musculoskeletal

Chronic Conditions Common in Older Adults: Cardiovascular, Respiratory, and Musculoskeletal

Older adults frequently live with multiple chronic conditions at once. As an LPN, your role is to monitor, report, and support—working within your scope of practice while keeping the registered nurse (RN) and care team informed. This lesson covers heart failure, COPD, osteoporosis, and osteoarthritis, with special attention to how these conditions look differently in older adults.

Why Older Adults Present Differently

Aging changes how the body responds to illness. Blunted immune response, decreased physiologic reserve, polypharmacy, and changes in pain perception all contribute to atypical presentations. A classic example: an older adult having a myocardial infarction (MI) may not report crushing chest pain. Instead, the first signs may be sudden confusion, extreme fatigue, nausea, or shortness of breath. Similarly, a urinary tract infection in an elder may present as confusion before any urinary symptoms appear. Always think broadly when assessing an older adult with a new or worsening change in mental status.

Heart Failure

Pathophysiology (brief review): Heart failure occurs when the heart cannot pump enough blood to meet the body's demands. In older adults, hypertension and coronary artery disease are common underlying causes. Both systolic dysfunction (reduced ejection fraction) and diastolic dysfunction (stiff, non-compliant ventricle) occur with aging.

Atypical presentations in elders: Older adults may not report classic dyspnea on exertion. Instead, watch for increased fatigue, anorexia, confusion, nocturia, and a dry, persistent cough (especially with ACE inhibitor use). Bilateral ankle edema and sudden weight gain (fluid retention) are important objective findings.

Nursing priorities:

• Weigh patient daily at the same time, in the same clothing; report a weight gain of 2–3 pounds in 24 hours or more than 5 pounds in a week to the RN.
• Monitor fluid intake and output; assess breath sounds for crackles (rales).
• Position patient in semi-Fowler's or high-Fowler's to reduce cardiac workload and ease breathing.
• Administer medications as ordered (diuretics, ACE inhibitors, beta-blockers) and monitor for side effects such as electrolyte imbalance.
• Priority reportable signs: sudden increase in dyspnea, new or worsening crackles, oxygen saturation below the facility threshold, or acute confusion.

Chronic Obstructive Pulmonary Disease (COPD)

Pathophysiology (brief review): COPD includes emphysema and chronic bronchitis, causing airflow obstruction that is not fully reversible. Air trapping leads to a barrel chest appearance over time. Hypoxemia and hypercapnia are ongoing concerns.

Atypical presentations in elders: Older adults may have gradually reduced activity to accommodate dyspnea, masking how severe their disease has become. Exacerbations may present as increased confusion, decreased appetite, or simply "not acting right" before obvious respiratory distress appears.

Nursing priorities:

• Monitor respiratory rate, depth, effort, and oxygen saturation continuously during exacerbations.
• Administer supplemental oxygen as ordered—use caution in patients with known CO2 retention; follow the prescribed flow rate carefully.
• Encourage pursed-lip breathing and sitting in a tripod position to maximize lung expansion.
• Administer bronchodilators and corticosteroids as ordered; teach proper inhaler technique.
• Priority reportable signs: respiratory rate above or below the established parameters, accessory muscle use, cyanosis, confusion, SpO2 dropping below ordered parameters.

Osteoporosis

Pathophysiology (brief review): Osteoporosis is a systemic disease characterized by low bone mass and deterioration of bone tissue, increasing fracture risk. Postmenopausal women and older men are most affected. The spine, hip, and wrist are common fracture sites.

Atypical presentations in elders: Vertebral compression fractures often occur with minimal or no trauma and may be discovered incidentally. Back pain may be the only complaint, or the patient may report losing height or notice a kyphotic posture developing.

Nursing priorities:

• Implement fall prevention measures: bed in lowest position, call light within reach, non-skid footwear, clear pathways.
• Assist with ambulation and encourage weight-bearing activity as tolerated and ordered.
• Ensure dietary calcium and vitamin D intake as directed; administer bisphosphonates or other prescribed medications correctly (bisphosphonates require specific administration instructions—typically taken with a full glass of water, patient remains upright for at least 30 minutes).
• Priority reportable signs: new fall, acute back pain, sudden loss of mobility, suspected fracture, or any sign of deformity.

Osteoarthritis

Pathophysiology (brief review): Osteoarthritis (OA) is the progressive breakdown of articular cartilage, most commonly affecting knees, hips, hands, and the spine. It is the most common form of arthritis in older adults.

Atypical presentations in elders: Pain may be under-reported because elders normalize it as "just aging." Functional decline (difficulty rising from a chair, reduced grip strength) may be the first observable concern rather than a pain complaint.

Nursing priorities:

• Assess pain using an appropriate scale; ask about stiffness (typically worst in the morning but brief—lasting less than 30 minutes, unlike rheumatoid arthritis).
• Encourage gentle range-of-motion (ROM) exercises and activity as tolerated.
• Apply heat or cold therapy as ordered to affected joints.
• Administer analgesics as ordered; monitor older adults carefully for NSAID side effects (GI bleeding, renal effects, cardiovascular risk).
• Assist with assistive devices (walkers, canes, splints) and collaborate with physical and occupational therapy.
• Priority reportable signs: sudden severe joint pain, signs of joint infection (warmth, redness, fever), acute loss of joint function, or signs of GI bleeding in patients on NSAIDs.

Scope of Practice Reminder

As an LPN, you observe, document, and report findings to the RN. You do not independently make medical diagnoses or change care plans, but your timely, accurate assessment can prevent serious harm. When in doubt about whether a finding is urgent, report it—it is always better to communicate early.
