Lesson Objectives

Differentiate osteoarthritis (OA), rheumatoid arthritis (RA), and gout by cause, findings, and priority nursing care.
Explain how each disrupts normal joint physiology and why the classic symptoms occur.
Justify treatments—acetaminophen/NSAIDs (OA), DMARDs/biologics (RA), colchicine/NSAIDs + allopurinol (gout)—and the reasoning behind each.
Teach the key self-management: joint protection/weight loss (OA), medication adherence (RA), and low-purine diet (gout).
Interpret relevant labs (RF, anti-CCP, ESR/CRP, uric acid) and use the NCSBN Clinical Judgment model.

Why This Matters

Prevalence: joint disorders are extremely common—osteoarthritis is the most common form of arthritis (millions of older adults), rheumatoid arthritis is a leading autoimmune cause of disability (more common in women), and gout is a common, painful crystal arthritis (rising with diet/obesity). Nurses see these across primary care, med-surg, and rehab.

Patient safety: these disorders cause chronic pain, deformity, disability, and reduced function/quality of life; RA and gout can also affect other organs (RA → lungs/heart/eyes; chronic gout → kidney stones/damage). Their medications carry important risks (NSAID GI/renal effects, DMARD immunosuppression).

NCLEX importance: heavily tested on OA vs. RA differences, gout (uric acid, acute vs. chronic treatment, allopurinol timing, low-purine diet), DMARD/methotrexate safety, and joint-protection teaching. Builds on the A&P of joints/cartilage and the immune-disorder lesson (RA).

Why nurses encounter it constantly: nurses manage pain and mobility, teach medications and joint protection, support joint-replacement and DMARD therapy, and coach diet (gout)—daily med-surg and community nursing.

Connecting to prior lessons From A&P, recall that cartilage cushions joints and synovial fluid lubricates them. From assessment, recall checking joint pain, swelling, deformity, ROM, and morning stiffness. These disorders are the joint damaged three different ways: cartilage wears out (OA), the immune system attacks it (RA), or crystals deposit in it (gout).

Disease Overview

Disorder	Core problem & meaning
Osteoarthritis (OA)	Degenerative "wear-and-tear" loss of cartilage in weight-bearing joints (knees, hips, spine) and hands → pain worse with use, brief morning stiffness, and bony nodes. Not a systemic/inflammatory disease (localized).
Rheumatoid arthritis (RA)	Autoimmune, systemic inflammation of the synovium, attacking joints symmetrically (small joints of hands/wrists/feet) → morning stiffness >1 hour, fatigue/fever, and deformities; flares and remissions.
Gout	Uric acid crystals deposit in joints (from high uric acid) → sudden, severe attacks (classically the big toe—podagra) that are red, hot, swollen; chronic disease forms tophi and can damage kidneys.

Analogy — three ways a hinge fails

Picture a joint as a door hinge. In osteoarthritis, the hinge is worn out from years of use—the cushioning wears away and it grinds (worse the more you use it). In rheumatoid arthritis, the body's own "repair crew" turns saboteur and attacks the hinge on both doors at once (symmetric, systemic inflammation → deformity). In gout, sharp crystals (uric acid) get into the hinge and cause a sudden, fiery attack (often the big toe). Same joint pain—three totally different causes and fixes.

What They Look Like

OA hand · RA hand · gout (big toe) OSTEOARTHRITIS Bony nodes (Heberden/Bouchard), asymmetric; worse with use RHEUMATOID Symmetric swollen small joints, deformity (swan-neck/ulnar drift) GOUT (big toe) Uric acid crystals → red, hot, swollen big toe (podagra); tophi later

OA = bony nodes (Heberden/Bouchard), asymmetric, weight-bearing joints, worse with use. RA = symmetric swollen small joints with deformity and systemic symptoms. Gout = a sudden, red, hot, swollen joint (classically the big toe) from uric acid crystals.

Pathophysiology

Normal physiology: cartilage cushions the joint, synovial fluid lubricates it, and the immune system leaves the joint alone; uric acid (a waste product) is cleared by the kidneys. ↓ What goes wrong: OA = cartilage wears down (age, overuse, obesity) → bone rubs on bone. RA = the immune system attacks the synovium (autoimmune inflammation). Gout = too much uric acid forms crystals that deposit in joints. ↓ How symptoms appear: OA → joint pain worse with activity, brief (<30 min) morning stiffness, crepitus, and bony nodes. RA → symmetric joint pain/swelling, morning stiffness >1 hour, fatigue/fever, and deformities. Gout → sudden severe pain, redness, heat, and swelling (often the big toe). ↓ How it progresses: OA → progressive joint damage/disability (may need joint replacement). RA → joint destruction/deformity and systemic organ involvement. Gout → recurrent attacks, tophi, and kidney stones/damage. Treatment slows or controls each. NCLEX Clinical Pearl — OA vs. RA in one breath OA = wear-and-tear, ASYMMETRIC, weight-bearing joints, brief morning stiffness (<30 min), worse with USE, NO systemic symptoms. RA = autoimmune, SYMMETRIC small joints, morning stiffness >1 HOUR, systemic (fatigue/fever), better with movement. Gout = uric acid crystals, sudden red/hot/swollen joint (big toe). This contrast is the most tested idea in the topic.

Risk Factors

Non-modifiable	Modifiable	Preventable / reducible
OA: older age, female, genetics, prior joint injury RA: female, family history, genetics Gout: male, family history, age	OA: obesity, joint overuse/injury RA: smoking Gout: high-purine diet (red/organ meat, shellfish), alcohol (esp. beer), obesity, dehydration, some diuretics	OA: weight management, joint protection, exercise RA: smoking cessation, early treatment Gout: low-purine diet, limit alcohol, hydration, maintain healthy weight, uric-acid-lowering therapy

High-risk populations: older/obese adults and those with joint injury (OA); women and smokers (RA); and men with high-purine diets, alcohol use, obesity, or on certain diuretics (gout). Weight and diet/alcohol are big modifiable factors for OA and gout respectively.

Signs & Symptoms

Category	Findings & WHY they occur
Osteoarthritis	Joint pain worse with activity/end of day, brief morning stiffness (<30 min), crepitus, decreased ROM, and bony nodes (Heberden's at DIP, Bouchard's at PIP)—cartilage loss in weight-bearing/hand joints; asymmetric, no systemic symptoms.
Rheumatoid arthritis	Symmetric joint pain/swelling/warmth (hands, wrists, feet), morning stiffness >1 hour, fatigue, low-grade fever, and deformities (swan-neck, ulnar deviation)—systemic autoimmune inflammation; flares/remissions.
Gout (acute)	Sudden, severe joint pain (often the big toe—podagra), redness, heat, swelling, and extreme tenderness—uric acid crystals trigger intense inflammation (often at night).
Gout (chronic)	Tophi (urate deposits under the skin), recurrent attacks, and possible kidney stones—long-standing high uric acid.
Emergency/urgent findings	A hot, swollen, acutely painful joint with fever—rule out septic (infected) joint (a true emergency, distinct from gout). Signs of NSAID complications (GI bleed) or DMARD infection.

Why a hot, swollen joint with fever must be evaluated Gout can look like an infected joint—but a septic (infected) joint is an emergency that can destroy the joint quickly. A single hot, red, swollen, extremely painful joint with fever should be evaluated (joint aspiration) to distinguish gout (uric acid crystals) from infection (bacteria)—don't assume it's "just gout." Notify the provider.

Nursing Assessment

Subjective: joint pain (which joints, symmetric?, timing—worse with use or after rest?, morning stiffness duration), swelling, fatigue/fever (RA), sudden severe attacks (gout), diet/alcohol, and functional/ADL limits.

Objective: joints (swelling, warmth, redness, deformity, nodes/tophi, symmetry), ROM, gait, and functional status; vital signs (fever with RA flare or septic joint). Correlate with RF/anti-CCP, ESR/CRP, and uric acid.

Priority / focused finding	Why it matters / action
Hot, red, swollen joint + fever	Rule out septic joint—notify, aspiration; also acute gout.
Symmetric swollen small joints + >1 hr stiffness	RA—assess systemic involvement, support DMARD care.
Asymmetric weight-bearing joint pain worse with use	OA—joint protection, pain/function support.
Sudden severe big-toe pain	Acute gout—treat the attack; don't start allopurinol now.
Signs of med complications (GI bleed, infection)	NSAID/DMARD safety—monitor and report.

Red flags — notify / act now A hot, swollen joint with fever (possible septic joint), GI bleeding (NSAID complication—dark stools, hematemesis), and signs of infection in a client on DMARDs/biologics/steroids. Notify the provider promptly.

Diagnostic Tests

Test	Purpose / why ordered	Findings, prep & nursing considerations
X-ray	Assess joint damage	OA: joint space narrowing, osteophytes (bone spurs). RA: erosions/deformity. Painless.
Joint aspiration (arthrocentesis)	Analyze synovial fluid (gout vs. infection vs. RA)	Gout: uric acid (urate) crystals. Septic joint: bacteria/pus. Sterile technique; monitor site.
Serologic tests (RA) — RF, anti-CCP, ANA	Support RA diagnosis	RF and anti-CCP positive in RA (anti-CCP is specific).
Serum uric acid (gout)	Assess/monitor gout	Often elevated (but can be normal during an acute attack); trend to guide therapy.
Inflammatory markers (ESR, CRP)	Assess inflammation/disease activity	Elevated in RA (and infection); track flares/response.

Patient teaching — testing Explain that joint aspiration both relieves pressure and identifies the cause (crystals = gout; bacteria = infection), and that RF/anti-CCP support an RA diagnosis. For gout, note that uric acid may be normal during an acute attack, so diagnosis relies on the clinical picture and crystals.

Laboratory Tests

Lab	Normal range	Significance & trend
Serum uric acid (gout)	~3.5–7.2 mg/dL	Elevated (hyperuricemia) in gout; monitor to guide urate-lowering therapy (goal <6). May be normal during an acute flare.
RF & anti-CCP (RA)	Negative	Positive supports RA; anti-CCP is specific and predicts more erosive disease.
ESR & CRP	Low	Elevated with active inflammation (RA, infection); track disease activity/flares.
CBC, LFTs, renal function (on therapy)	Normal	Monitor for methotrexate/DMARD toxicity (bone marrow, liver) and NSAID renal effects.
ANA	Negative	Can be positive in RA/other autoimmune disease.

NCLEX pearl — each disorder has its lab Gout → uric acid (and urate crystals on aspiration). RA → RF/anti-CCP + ESR/CRP. OA → mostly a clinical/X-ray diagnosis (labs are usually normal). On methotrexate, monitor CBC and liver function.

Medications

Osteoarthritis

Class / drug	Mechanism, use & key nursing/NCLEX points
Acetaminophen	First-line for OA pain (safer for many older adults). Watch total daily dose (hepatotoxicity)—teach the max and to avoid combining acetaminophen products.
NSAIDs — ibuprofen, naproxen; topical NSAIDs	Reduce pain/inflammation. GI bleeding and renal/cardiovascular risks—take with food, use lowest dose; caution in older adults/renal disease. Topical NSAIDs for localized OA.
Intra-articular corticosteroid injections	Reduce localized joint inflammation/pain (temporary relief).
(Surgery)	Severe OA → joint replacement (see fractures/trauma lesson).

Rheumatoid arthritis

Class / drug	Mechanism, use & key nursing/NCLEX points
DMARDs — methotrexate (first-line), hydroxychloroquine, sulfasalazine	Slow disease progression/joint destruction. Methotrexate: teratogen (Black Box), monitor CBC and liver function, give folic acid, avoid alcohol, infection risk; hydroxychloroquine → eye exams.
Biologics — etanercept, adalimumab (TNF inhibitors), etc.	Target immune signals for moderate–severe RA. Screen for latent TB before starting; high infection risk; avoid live vaccines.
Corticosteroids — prednisone	Control flares (fast anti-inflammatory). Short-term; taper; watch infection/glucose/bone loss.
NSAIDs	Symptom relief (don't slow disease)—use with DMARDs.

Gout

Drug	Why given & nursing
Acute attack: NSAIDs, colchicine, or corticosteroids	Stop the acute inflammation. Colchicine works best early; causes GI upset/diarrhea. Do NOT start urate-lowering therapy during an acute attack (can worsen/prolong it).
Prevention (chronic): allopurinol, febuxostat (xanthine oxidase inhibitors); probenecid	Lower uric acid to prevent attacks—started when NOT in an acute flare. Increase fluids (prevent stones); allopurinol → rash (report—rare severe reaction). Continue even when symptom-free.

Safety — the gout timing rule & DMARD/NSAID risks Treat the acute gout attack first (NSAIDs/colchicine/steroids); start allopurinol only after the attack resolves (starting it during a flare can worsen it), and don't stop it once started (continue for prevention). Methotrexate = teratogen, monitor CBC/LFTs, give folic acid. NSAIDs = GI bleed/renal risk. Biologics = TB screen/infection risk. NCLEX testing points OA → acetaminophen (first-line), NSAIDs, weight loss/exercise, joint replacement. RA → DMARDs (methotrexate—labs/folic acid), biologics (TB screen), steroids for flares. Gout → acute: colchicine/NSAIDs/steroids; prevention: allopurinol (not during a flare) + low-purine diet + fluids.

Nursing Interventions

Priority	Intervention & WHY
Pain & comfort	Give analgesics/anti-inflammatories as ordered; use heat for stiffness (OA) and cold for acute inflammation (RA flare/gout); rest inflamed joints—reduce pain and inflammation.
Preserve joint function/mobility	Balance rest and gentle exercise/ROM, use assistive devices, and teach joint protection (proper body mechanics, avoid overuse)—maintain function and prevent deformity.
Medication safety	Monitor NSAID GI/renal effects, methotrexate labs (CBC/LFTs), infection on DMARDs/biologics, and gout medication timing—prevent complications.
Nutrition (gout)	Teach a low-purine diet (limit red/organ meats, shellfish), limit alcohol, increase fluids, and manage weight—lower uric acid and prevent attacks/stones.
Weight management (OA)	Support weight loss to reduce joint load and low-impact exercise—slow OA progression.
Safety	Fall prevention (limited mobility), infection prevention (immunosuppressants), and monitoring for med side effects.
Patient education	Medication adherence, joint protection, diet, exercise, and warning signs—self-management preserves function.
Interdisciplinary	Rheumatology, PT/OT (exercise/assistive devices/joint protection), dietitian (gout), pharmacy, and orthopedics (joint replacement).

Why heat and cold are used differently Heat relaxes muscles and eases stiffness—helpful for OA and morning stiffness in RA. Cold constricts vessels and reduces acute inflammation and swelling—helpful during an RA flare or an acute gout attack. Matching the therapy to the problem (stiff vs. inflamed) is why the nurse chooses one over the other.

Potential Complications

Complication	Early signs	Nursing response
Joint deformity/disability (RA, OA)	Progressive deformity, loss of function	DMARDs/joint protection/PT; assistive devices; possible surgery.
Septic joint (mimics gout)	Hot, swollen, painful joint + fever	Urgent aspiration/antibiotics; distinguish from gout.
Kidney stones/damage (gout)	Flank pain, hematuria, high uric acid	Hydration, urate-lowering therapy, monitor renal function.
NSAID GI bleed / renal injury	Dark stools, abdominal pain, rising creatinine	Hold NSAID, notify provider, monitor H&H/renal.
DMARD/biologic infection or toxicity	Fever/infection, abnormal CBC/LFTs	Monitor labs, infection precautions, notify provider.
Systemic RA involvement	Lung, cardiac, eye, or vascular symptoms	Monitor and refer; manage systemic disease.

Patient Education

Disease process: explain whether the joint problem is wear-and-tear (OA), autoimmune (RA), or crystal-related (gout)—it drives the plan. OA: lose weight, do low-impact exercise (walking, swimming), use joint protection and assistive devices, apply heat for stiffness, and take acetaminophen/NSAIDs as directed (know acetaminophen limits). RA: take DMARDs consistently even when feeling well (they prevent joint destruction), get lab monitoring, prevent infection (avoid live vaccines on biologics), balance rest and gentle exercise, use heat/cold appropriately, and don't stop steroids abruptly. Gout: follow a low-purine diet (limit red meat, organ meats, and shellfish), limit alcohol (especially beer), drink plenty of fluids (prevent stones), maintain a healthy weight, take acute-attack medications early, and continue allopurinol for prevention (started only between attacks—don't stop it). General: pace activities, protect joints, and manage weight. Follow-up: rheumatology, lab monitoring, and provider visits. Warning signs / when to seek emergency care: a hot, swollen joint with fever (possible infection), GI bleeding (dark/bloody stools) on NSAIDs, signs of infection on immunosuppressants, or a severe medication rash—seek care.

Clinical Judgment (NCSBN Model)

Recognize cues: a 55-year-old man wakes at night with sudden, severe pain, redness, heat, and swelling of the right great toe; he can't bear even a bedsheet on it. He recently had a large steak dinner and several beers. Serum uric acid is elevated; aspiration shows urate crystals.
Analyze cues: sudden severe monoarticular (big toe) pain + redness/heat/swelling + high uric acid + urate crystals + dietary/alcohol trigger = acute gout (podagra). (Rule out a septic joint if fever/uncertain.)
Prioritize hypotheses: relieve the acute attack and prevent recurrence—pain and inflammation control are the priority.
Generate solutions: give acute-attack medication (NSAID, colchicine, or corticosteroid), rest/elevate/apply cold to the joint, increase fluids, and do NOT start allopurinol during the attack; teach low-purine diet and alcohol limits; plan urate-lowering therapy after the flare.
Take action: treat the attack, comfort measures, hydration, and teaching.
Evaluate outcomes: is the pain/inflammation resolving? Then start/continue allopurinol between attacks, reinforce diet, alcohol limits, fluids, and adherence to prevent recurrent attacks and kidney stones.

Clinical Connections — commonly confused

	Osteoarthritis	Rheumatoid Arthritis	Gout
Cause	Wear-and-tear cartilage loss	Autoimmune, systemic inflammation	Uric acid crystals
Pattern	Asymmetric, weight-bearing/hand joints	Symmetric, small joints (hands/wrists/feet)	Sudden, often big toe (monoarticular)
Stiffness/pain	Brief AM stiffness (<30 min); worse with use	AM stiffness >1 hour; systemic (fatigue/fever)	Sudden severe attack; red/hot/swollen
Diagnostics	X-ray (narrowing/osteophytes); normal labs	RF/anti-CCP, ESR/CRP	Uric acid; urate crystals on aspiration
Treatment	Acetaminophen/NSAIDs, weight loss, replacement	DMARDs, biologics, steroids	Acute: colchicine/NSAIDs/steroids; prevent: allopurinol + low-purine diet

Key confusion: OA = asymmetric, brief stiffness, worse with use, no systemic symptoms; RA = symmetric, >1 hr stiffness, systemic; gout = sudden crystal attack. Also distinguish acute gout from a septic joint (infection + fever).

NCLEX High-Yield Review

What the NCLEX Wants You to Know

OA = asymmetric, brief AM stiffness, worse with use, no systemic signs
RA = symmetric small joints, AM stiffness >1 hr, systemic; DMARDs slow it
Gout = uric acid crystals, big toe; low-purine diet + fluids
Allopurinol prevents gout — NOT started during an acute attack
Methotrexate: monitor CBC/LFTs, give folic acid, teratogen

Frequently tested findings: OA nodes/asymmetry, RA symmetry + prolonged stiffness + systemic signs, and gout's sudden red/hot big toe. Common distractors: starting allopurinol during a flare, confusing OA and RA stiffness patterns, high-purine foods for gout, and stopping DMARDs when symptom-free. Priority interventions: acute gout/RA flare pain relief, joint protection, medication safety, and diet (gout). Expected vs unexpected: chronic joint pain/stiffness is expected; a hot joint with fever (septic), GI bleed (NSAID), or infection (DMARD) are urgent. Patient teaching: weight loss/exercise (OA), DMARD adherence (RA), low-purine diet/fluids/allopurinol timing (gout), heat vs. cold. Safety: NSAID GI/renal risk, methotrexate labs/folic acid, TB screen before biologics, allopurinol timing. Delegation: RN assesses, interprets labs, and gives DMARDs/teaching; UAP can assist with ADLs, apply heat/cold (per plan), help with ambulation, and report—not assess or medicate. Frequently tested meds: acetaminophen, NSAIDs, methotrexate, biologics, colchicine, allopurinol. Critical labs: uric acid, RF/anti-CCP, ESR/CRP, CBC/LFTs. Most common mistakes: allopurinol during a flare, confusing OA/RA, and high-purine gout diet.

Memory Aids

OA vs. RA "A" words: "RA = Autoimmune, AM stiffness >1 hr, All symmetric"; OA = Asymmetric, Aging/wear, brief stiffness.
OA nodes: "Heberden's = Distal (top, DIP); Bouchard's = Between/PIP." (Bouchard's = closer to the Body.)
Gout "big toe = podagra" — sudden red/hot/swollen; from uric acid crystals.
Gout diet "avoid the 3 P's + booze": Purine-rich meats/organ, Plenty of alcohol, and dehydration — drink Plenty of water.
Allopurinol "A for Always (prevention), not Acute": lowers uric acid long-term—don't start it during an attack.
Heat vs. cold: "Heat for stiff (OA/AM), Cold for hot (inflamed flare/gout)."

Case Study — from admission to discharge

Admission. Ms. Delacroix, 62, presents with symmetric pain, swelling, and warmth in both hands and wrists, plus morning stiffness lasting about 2 hours, fatigue, and a low-grade fever. Labs: positive RF and anti-CCP, elevated ESR/CRP. She is diagnosed with rheumatoid arthritis and started on methotrexate.

Step 1–2: Recognize & analyze cues

Cues: symmetric small-joint involvement, prolonged morning stiffness (>1 hr), systemic symptoms (fatigue/fever), and positive RF/anti-CCP + high ESR/CRP = rheumatoid arthritis (autoimmune, systemic). Risk: joint destruction/deformity and med side effects.

Step 3–4: Prioritize & plan

Priority: control inflammation/slow disease and manage pain/function safely. Plan: start methotrexate (with folic acid), monitor CBC/LFTs, teach infection prevention, balance rest and gentle exercise, use heat/cold appropriately, and manage pain.

Step 5: Take action

The nurse gives/teaches methotrexate (labs, folic acid, avoid alcohol, teratogen precautions, infection prevention), teaches joint protection and energy conservation, and coordinates PT/OT and rheumatology follow-up.

Step 6: Evaluate & discharge

Symptoms improve on therapy. Discharge teaching: take DMARDs consistently even when feeling well, keep lab monitoring, prevent infection (avoid live vaccines on biologics), balance activity and rest, use heat/cold, and seek care for signs of infection, a hot swollen joint, or severe side effects.

NCLEX Practice Questions

1. Which finding is most characteristic of rheumatoid arthritis rather than osteoarthritis?

Symmetric small-joint involvement with morning stiffness lasting more than an hour
Asymmetric knee pain that worsens with activity
Bony nodes on the fingers without systemic symptoms
Sudden severe pain in the great toe

Rationale

Answer: 1. RA is symmetric, involves small joints, and causes morning stiffness >1 hour with systemic symptoms. Asymmetric activity-worsened knee pain (2) and bony nodes without systemic signs (3) describe OA; sudden great-toe pain (4) is gout.

2. A client with gout is started on allopurinol. Which statement indicates correct understanding?

"I'll take it only when I have an acute attack."
"I should stop drinking fluids while on this drug."
"This medicine lowers my uric acid to prevent future attacks, and I take it regularly, not during a flare."
"I can eat organ meats and shellfish freely now."

Rationale

Answer: 3. Allopurinol lowers uric acid to prevent attacks and is taken regularly (not started during an acute flare). It's not PRN (1), fluids should be increased (2), and a low-purine diet (limit organ meats/shellfish) is still needed (4).

3. A client with osteoarthritis asks how to reduce joint pain. Which teaching is appropriate?

Perform high-impact running daily
Lose weight and do low-impact exercise such as swimming or walking
Keep the joints completely immobile at all times
Take methotrexate to slow the disease

Rationale

Answer: 2. Weight loss and low-impact exercise reduce joint load and maintain function in OA. High-impact running (1) stresses joints, complete immobility (3) worsens stiffness/function, and methotrexate (4) is for RA, not OA.

4. A client presents with a sudden, red, hot, swollen great toe and cannot tolerate a sheet touching it. Which finding would confirm gout?

Positive rheumatoid factor
Joint-space narrowing on X-ray
Symmetric hand involvement
Uric acid crystals in the joint fluid

Rationale

Answer: 4. Uric acid (urate) crystals in synovial fluid confirm gout. RF (1) supports RA, joint-space narrowing (2) suggests OA, and symmetric hand involvement (3) is RA.

5. A client with rheumatoid arthritis is taking methotrexate. Which teaching is essential?

Methotrexate provides immediate pain relief within hours
Alcohol use is encouraged to reduce side effects
Regular blood tests are needed to monitor the blood counts and liver, and pregnancy must be avoided
Live vaccines are recommended while taking it

Rationale

Answer: 3. Methotrexate requires CBC and liver monitoring, is a teratogen (avoid pregnancy), and includes folic acid. It works slowly (1), alcohol increases liver toxicity (2), and live vaccines are avoided during immunosuppression (4).

6. SATA. Which findings are consistent with osteoarthritis? Select all that apply.

Asymmetric joint involvement
Pain that worsens with activity and improves with rest
Morning stiffness lasting more than 2 hours with fever
Heberden's and Bouchard's nodes on the fingers
Crepitus and decreased range of motion

Rationale

Answers: 1, 2, 4, 5. OA is asymmetric, worse with use, and causes bony nodes, crepitus, and reduced ROM. Prolonged morning stiffness >2 hours with fever (3) points to RA (systemic/inflammatory), not OA.

7. SATA. Which teaching points are appropriate for a client with gout? Select all that apply.

Limit red meat, organ meats, and shellfish
Drink plenty of fluids
Limit alcohol, especially beer
Start allopurinol during an acute flare
Maintain a healthy weight

Rationale

Answers: 1, 2, 3, 5. Low-purine diet, fluids, limiting alcohol, and weight management lower uric acid/attacks. Starting allopurinol during an acute flare (4) can worsen it—urate-lowering therapy is started between attacks.

8. Priority. A nurse is caring for four clients. Which client should the nurse assess first?

A client with a hot, swollen, extremely painful joint and a fever of 39 °C
A client with OA requesting a heating pad
A client with gout asking about diet
A client with RA requesting a PT referral

Rationale

Answer: 1. A hot, swollen, painful joint with a high fever suggests a septic (infected) joint—an emergency that can destroy the joint quickly and must be assessed first. The others are stable/routine.

9. Delegation. Which task can the RN appropriately delegate to unlicensed assistive personnel (UAP) for a client with a joint disorder?

Assessing joints for swelling and deformity
Teaching a low-purine diet
Interpreting the uric acid level
Applying a warm compress and assisting with ambulation per the plan of care

Rationale

Answer: 4. Applying a warm compress (per the plan) and assisting with ambulation are within UAP scope. Assessment (1), teaching (2), and interpreting labs (3) require the licensed nurse.

10. NGN Case Study. A 68-year-old woman reports gradual, activity-related pain in both knees and her right hip that improves with rest, with brief (about 20-minute) morning stiffness. Exam shows bony enlargement of the finger joints (Heberden's nodes), crepitus, and decreased ROM; labs (RF, ESR) are normal. X-ray shows joint-space narrowing and osteophytes.

a) What is happening and which cues support it?
b) What are the priority nursing actions and key teaching?

Model answer

a) What's happening: osteoarthritis. Supporting cues: activity-related joint pain relieved by rest, brief (<30 min) morning stiffness, Heberden's nodes, crepitus, decreased ROM, normal labs, and X-ray showing joint-space narrowing and osteophytes (degenerative, not inflammatory).

b) Priority actions/teaching: 1) pain/function management—acetaminophen (first-line) ± NSAIDs (with GI/renal caution), heat for stiffness, and joint protection. 2) Weight loss and low-impact exercise (walking/swimming), assistive devices, and energy conservation. 3) Discuss joint replacement for severe disease. Key teaching: pace activities, protect joints, maintain a healthy weight, and know medication limits (acetaminophen dose). Evaluate: improved pain/function, maintained mobility, and safe medication use.

Key Takeaways

Osteoarthritis = wear-and-tear cartilage loss: asymmetric, weight-bearing joints, brief morning stiffness (<30 min), worse with use, no systemic symptoms; bony nodes (Heberden's/Bouchard's). Treat with acetaminophen/NSAIDs, weight loss, exercise, joint replacement.
Rheumatoid arthritis = autoimmune, systemic: symmetric small joints, morning stiffness >1 hour, fatigue/fever, deformities; RF/anti-CCP positive. DMARDs (methotrexate—labs/folic acid) slow it; biologics (TB screen); steroids for flares.
Gout = uric acid crystals: sudden red/hot/swollen joint (big toe/podagra). Acute: colchicine/NSAIDs/steroids; prevention: allopurinol (started between attacks, not during) + low-purine diet + fluids.
Don't start allopurinol during an acute attack—and don't stop it once started.
Use heat for stiffness (OA/AM) and cold for acute inflammation (RA flare/gout).
Rule out a septic joint (hot joint + fever) from gout; watch NSAID GI/renal effects and DMARD infection/labs.
Each has its lab: gout → uric acid, RA → RF/anti-CCP/ESR/CRP, OA → clinical/X-ray (normal labs).
