🩺
📒 The 1-minute cheat sheet
🩺 Signs
Asymmetric weight-bearing joints
Pain worse w/ activity, better rest
Stiffness < 30 min, crepitus
📌 Nodes
Heberden (DIP), Bouchard (PIP)
No systemic signs (vs RA)
🧪 Meds
Acetaminophen 1st, then NSAIDs
🎓 Teach
Weight loss ↓ joint stress
Heat for stiffness, low-impact exercise
Balance activity w/ rest periods
📚 Osteoarthritis — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Osteoarthritis is a non-inflammatory, degenerative joint disease in which articular cartilage breaks down from wear and tear, leading to bone-on-bone friction. It is the most common form of arthritis, typically asymmetric, and worsens with age, obesity, and joint overuse. It affects weight-bearing joints like the hips and knees most.
🔑
Key points
Understand these first
Joint pain worsens with activity and weight-bearing and is relieved by rest.
Morning stiffness is brief, usually lasting less than 30 minutes.
Joint involvement is typically asymmetric, affecting hips, knees, spine, and hands.
Heberden's nodes (distal finger joints) and Bouchard's nodes (proximal joints) are characteristic.
Crepitus, a grating sensation, is felt with joint movement.
Unlike rheumatoid arthritis, it lacks systemic symptoms such as fever and fatigue.
✅
Nursing priorities
What to do, in order
Encourage weight loss to reduce stress on weight-bearing joints.
Apply heat to relieve stiffness and promote low-impact exercise like swimming or walking.
Administer acetaminophen as first-line and NSAIDs as ordered for pain.
Balance activity with rest and teach joint protection and proper body mechanics.
Promote use of assistive devices such as canes and supportive footwear.
🚩
Red flags — report now
Escalate immediately
Sudden joint swelling, redness, warmth, and fever may indicate infection rather than osteoarthritis.
Report GI bleeding signs (black stools, abdominal pain) in patients taking long-term NSAIDs.
🧪
Labs & values
Numbers to know
ESR: 0 to 20 mm/hr (usually normal, unlike RA)
Rheumatoid factor: negative (helps distinguish from RA)
🗣️
Patient teaching
What patients must know
Lose excess weight and perform low-impact exercise to protect and strengthen joints.
Apply heat for stiffness, take acetaminophen as directed, and take NSAIDs with food.
Use assistive devices, supportive shoes, and good body mechanics, and rest painful joints.
❓ Osteoarthritis: NCLEX FAQs
What are the priority nursing interventions for Osteoarthritis?
Encourage weight loss to reduce stress on weight-bearing joints. Apply heat to relieve stiffness and promote low-impact exercise like swimming or walking. Administer acetaminophen as first-line and NSAIDs as ordered for pain. Balance activity with rest and teach joint protection and proper body mechanics.
What are the warning signs of Osteoarthritis a nurse must report?
Sudden joint swelling, redness, warmth, and fever may indicate infection rather than osteoarthritis. Report GI bleeding signs (black stools, abdominal pain) in patients taking long-term NSAIDs.
What do I need to know about Osteoarthritis for the NCLEX?
Joint pain worsens with activity and weight-bearing and is relieved by rest. Morning stiffness is brief, usually lasting less than 30 minutes. Joint involvement is typically asymmetric, affecting hips, knees, spine, and hands. Heberden's nodes (distal finger joints) and Bouchard's nodes (proximal joints) are characteristic.
What patient teaching is important for Osteoarthritis?
Lose excess weight and perform low-impact exercise to protect and strengthen joints. Apply heat for stiffness, take acetaminophen as directed, and take NSAIDs with food. Use assistive devices, supportive shoes, and good body mechanics, and rest painful joints.
