A 68-year-old client with osteoarthritis of the knees is being assessed by the nurse during a routine clinic visit. Which assessment finding would be most characteristic of osteoarthritis?

Joint stiffness worsening with activity and improving with rest is characteristic of osteoarthritis due to mechanical wear, distinguishing it from inflammatory arthritis where stiffness improves with movement.

Core Nursing Explanation Key Concept Analysis: This question tests your ability to differentiate the clinical presentation of Osteoarthritis (OA) from other forms of arthritis, particularly Rheumatoid Arthritis (RA). OA is a degenerative joint disease caused by the breakdown of articular cartilage. The key pathophysiology is mechanical wear and tear, not systemic inflammation. This fundamental difference dictates the pattern of symptoms.

Answer Rationale: Key Point! In OA, joint pain and stiffness are directly related to use and weight-bearing. Cartilage loss and bone-on-bone friction cause symptoms that worsen with activity (as the joint is used) and improve with rest (when the mechanical stress is removed). This is the hallmark "mechanical" pain pattern of OA, making option ④ the most characteristic finding.

Distractor Analysis:
Watch out for confusion! Option ①, "Morning stiffness lasting more than 2 hours," is a classic sign of Rheumatoid Arthritis (RA). Inflammatory mediators accumulate in the joint during periods of inactivity, causing prolonged stiffness upon waking. OA stiffness is typically brief (

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in an orthopedic clinic. Mr. Johnson, a 68-year-old retired teacher with a history of OA in both knees, comes for a follow-up. He reports his knee pain is now worse, especially after his daily walk in the park, but feels better when he sits down to read. He denies fever or fatigue.

Nursing Intervention Strategy: 1. Assessment: Perform a focused musculoskeletal assessment. Inspect knees for bony enlargement, palpate for tenderness and crepitus (grating sensation), and assess active/passive range of motion (ROM). Use a pain scale to quantify his pain. Ask specifically: "How long does the stiffness last when you first get up in the morning?" 2. Nursing Diagnosis: Chronic Pain related to degenerative joint changes. Impaired Physical Mobility related to pain and stiffness. 3. Planning & Implementation: • Education on Activity Modification: Teach pacing – alternate walking with rest periods. Recommend low-impact exercises (swimming, stationary cycling) to maintain strength without excessive joint stress. • Pain Management: Reinforce proper use of prescribed analgesics (e.g., take acetaminophen before planned activity). Demonstrate application of warm compresses for morning stiffness or cold packs after activity to reduce inflammation. • Weight Management: Discuss the impact of weight on knee joints. Even a small amount of weight loss can significantly reduce pain. Provide dietary resources if needed. 4. Evaluation: Mr. Johnson will report decreased pain with activity modification and effective use of pain management strategies, and demonstrate safe exercise techniques.

Patient Safety and Precautions: Caution against overuse of NSAIDs (like ibuprofen) in older adults due to risks of GI bleeding and renal impairment. Assess fall risk due to pain and possible instability. Educate on using assistive devices (cane) correctly to reduce knee load. Nursing Procedure & Medication Flow • Joint Assessment Procedure: Inspect (deformity, swelling), Palpate (warmth, tenderness, crepitus), Move (active ROM, then passive ROM), Measure (joint circumference if swollen). • Medication Education for OA: Acetaminophen: Max dose typically 3000-4000 mg/day. Warn about hidden sources in cold medicines. NSAIDs: Take with food/milk. Monitor for black, tarry stools (sign of GI bleed). Topical analgesics (capsaicin): Wash hands after application; transient burning sensation is common. A Word from Your Senior Nurse "In the clinic, you'll see many older adults with knee or hip pain. The moment they tell you 'It hurts when I walk but gets better when I sit,' your nursing brain should light up with 'Osteoarthritis.' Your role goes beyond assessment. It's about empowering them. Teaching them how to pace their activities, manage their weight, and use medications safely can dramatically improve their quality of life. Remember, for the NCLEX and for real life, the story the patient tells you about their pain pattern is one of your most powerful diagnostic tools. Listen closely!"
