WGU D345 Comprehensive Study Guide: Dr Cole
Remediation for OA | 2026 Update with complete
solutions
1. Dr. Cole’s remediation plan for osteoarthritis emphasizes which
foundational intervention as the first-line treatment according to the WGU
D345 curriculum?
a) Patient education and self-management including weight loss and
low-impact exercise
Rationale: WiseMan Stuvia notes that Dr. Cole prioritizes non-
pharmacological measures; education empowers adherence to weight loss
(reduces joint load) and exercise (improves synovial fluid circulation).
2. In Dr. Cole’s OA remediation algorithm, which medication is recommended
for mild-to-moderate pain after acetaminophen failure?
c) Oral NSAIDs such as ibuprofen or naproxen
Rationale: Based on WiseMan Stuvia highlights, NSAIDs reduce
inflammation and pain but require GI and renal risk assessment;
acetaminophen is first-line due to safety profile.
3. According to Dr. Cole’s lecture on osteoarthritis pathophysiology, which
cytokine is primarily responsible for cartilage degradation in OA?
b) Interleukin-1 (IL-1)
Rationale: WiseMan Stuvia emphasizes IL-1 stimulates matrix
metalloproteinases (MMPs) that break down collagen and proteoglycans in
articular cartilage.

Remediation for OA | 2026 Update with complete

solutions

  1. Dr. Cole’s remediation plan for osteoarthritis emphasizes which foundational intervention as the first-line treatment according to the WGU D345 curriculum? a) Patient education and self-management including weight loss and low-impact exercise Rationale: WiseMan Stuvia notes that Dr. Cole prioritizes non- pharmacological measures; education empowers adherence to weight loss (reduces joint load) and exercise (improves synovial fluid circulation).
  2. In Dr. Cole’s OA remediation algorithm, which medication is recommended for mild-to-moderate pain after acetaminophen failure? c) Oral NSAIDs such as ibuprofen or naproxen Rationale: Based on WiseMan Stuvia highlights, NSAIDs reduce inflammation and pain but require GI and renal risk assessment; acetaminophen is first-line due to safety profile.
  3. According to Dr. Cole’s lecture on osteoarthritis pathophysiology, which cytokine is primarily responsible for cartilage degradation in OA? b) Interleukin-1 (IL-1) Rationale: WiseMan Stuvia emphasizes IL-1 stimulates matrix metalloproteinases (MMPs) that break down collagen and proteoglycans in articular cartilage.
  1. A patient with knee OA asks Dr. Cole about glucosamine. Which response aligns with the WGU D345 evidence-based remediation guide? d) “Evidence is mixed but some patients report modest pain relief; it is generally safe.” Rationale: WiseMan Stuvia notes that guidelines do not strongly recommend glucosamine due to inconsistent trial results, but it may be tried with patient supervision.
  2. Dr. Cole’s OA teaching plan states that which clinical finding differentiates osteoarthritis from rheumatoid arthritis? a) Heberden’s nodes and bony enlargement Rationale: WiseMan Stuvia identifies Heberden’s (DIP) and Bouchard’s (PIP) nodes as osteoarthritic bony overgrowth, versus rheumatoid’s soft tissue swelling and synovitis.
  3. In the WGU D345 remediation module, Dr. Cole recommends which type of exercise as most beneficial for hip OA? c) Low-impact aerobic and strengthening exercises like walking and water therapy Rationale: WiseMan Stuvia highlights that water therapy reduces joint stress while providing resistance; strengthening stabilizes the hip joint.
  4. According to Dr. Cole, what is the maximum safe daily dose of acetaminophen for an otherwise healthy older adult with OA? b) 3000 mg per day Rationale: WiseMan Stuvia states that recent guidelines lower the limit to

Rationale: WiseMan Stuvia clarifies that steroids reduce acute inflammation but do not slow disease progression; repeated use may accelerate cartilage loss.

  1. Which radiographic finding is considered the earliest sign of OA according to Dr. Cole’s remediation materials? c) Joint space narrowing Rationale: WiseMan Stuvia emphasizes that loss of cartilage appears as asymmetric joint space narrowing on weight-bearing views before osteophytes form.
  2. Dr. Cole’s OA management algorithm for the D345 exam recommends referral for total joint arthroplasty when which condition is met? d) Severe pain and functional limitation despite optimal non-surgical treatment for ≥6 months Rationale: WiseMan Stuvia notes that surgery is reserved for end-stage OA with failure of conservative care; timing balances risks and benefits.
  3. According to Dr. Cole, which patient characteristic is a contraindication for using duloxetine in OA pain management? a) Uncontrolled narrow-angle glaucoma Rationale: WiseMan Stuvia highlights that duloxetine (SNRI) can increase intraocular pressure; also avoid with MAOIs or heavy alcohol use.
  4. In the WGU D345 remediation, Dr. Cole identifies which comorbidity as most likely to worsen OA progression?

b) Obesity Rationale: WiseMan Stuvia indicates obesity increases mechanical load and systemic inflammatory mediators (adipokines) that accelerate cartilage breakdown.

  1. What is the primary non-pharmacologic intervention Dr. Cole recommends for first-line management of hand OA? b) Splinting and adaptive equipment to reduce joint stress Rationale: Hand OA benefits from resting splints for flare-ups and ergonomic tools to preserve joint alignment during daily tasks.
  2. According to Dr. Cole, which gait abnormality is most common in patients with advanced knee OA? c) Antalgic gait with shortened stance phase on the affected side Rationale: Patients avoid weight-bearing on painful knee, leading to a limp and reduced stance time on the OA side.
  3. Dr. Cole’s remediation guide states that which laboratory finding is typically normal in primary OA? a) Rheumatoid factor and anti-CCP Rationale: OA is non-inflammatory; normal RF and anti-CCP help distinguish from rheumatoid arthritis.
  4. In the D345 curriculum, Dr. Cole recommends which baseline test before starting long-term NSAID therapy? d) Serum creatinine and complete blood count
  1. In the WGU D345 study guide, Dr. Cole states that which vitamin deficiency may be associated with OA progression? b) Vitamin D Rationale: Low vitamin D impairs bone remodeling and may accelerate cartilage loss; supplementation is reasonable but not proven to halt OA.
  2. Dr. Cole’s algorithm for OA management suggests adding which medication for patients with refractory pain and contraindications to NSAIDs? c) Tramadol Rationale: Tramadol is a weak opioid with serotonin/norepinephrine reuptake inhibition; used short-term for severe OA pain when other options fail.
  3. According to Dr. Cole, which joint is most commonly affected by primary OA? a) Knees Rationale: Knee OA is most prevalent due to weight-bearing load and ligamentous anatomy; hips and hands follow.
  4. Dr. Cole teaches that “morning stiffness” in OA typically lasts less than how many minutes? b) 30 minutes Rationale: OA stiffness is brief (<30 min) and improves with movement; prolonged stiffness suggests inflammatory arthritis.
  1. In the D345 remediation, which injection is contraindicated in a patient with septic arthritis risk? d) Intra-articular corticosteroid Rationale: Steroid injection into an infected joint can worsen infection; absolute contraindication if septic arthritis suspected.
  2. Dr. Cole recommends which assistive device for a patient with unilateral knee OA to reduce joint load? c) Contralateral cane (held in opposite hand) Rationale: Holding a cane in the hand opposite the painful knee reduces adduction moment and joint load by up to 30%.
  3. According to Dr. Cole, which surgical procedure is the definitive treatment for end-stage knee OA? a) Total knee arthroplasty Rationale: Total knee replacement is the gold standard for end-stage OA when conservative measures fail; unicompartmental or osteotomy are alternatives.
  4. Dr. Cole’s remediation notes that which occupation is a risk factor for developing hip OA? b) Farming with heavy lifting Rationale: Repetitive heavy lifting and prolonged squatting increase cumulative joint stress, raising OA risk in hips and knees.
  5. In the WGU D345 comprehensive guide, which pain pattern suggests concomitant OA and neuropathic pain?

Rationale: COL2A1 mutations affect type II collagen in cartilage, leading to early-onset OA; other genes also contribute but less defined.

  1. A patient with knee OA and hypertension asks Dr. Cole about safe pain management. Which medication is preferred? c) Topical diclofenac Rationale: Topical NSAIDs have minimal systemic absorption and do not raise blood pressure, unlike oral NSAIDs or COX-2 inhibitors.
  2. Dr. Cole’s teaching plan for OA includes which recommendation regarding braces? a) Unloader knee brace for medial compartment OA Rationale: Unloader braces shift weight away from the affected compartment, reducing pain and improving function in unicompartmental OA.
  3. According to Dr. Cole, which supplement has the strongest evidence for slowing OA progression? b) No supplement has proven disease-modifying effects Rationale: Current guidelines indicate that no supplement (glucosamine, chondroitin, etc.) definitively slows structural progression of OA.
  4. Dr. Cole states that which comorbidity most increases the risk of NSAID-related acute kidney injury? d) Chronic kidney disease stage 3 or higher Rationale: Pre-existing CKD reduces renal reserve, making patients highly

susceptible to NSAID-induced prerenal injury and acute interstitial nephritis.

  1. In the WGU D345 remediation, Dr. Cole describes “osteophytes” as which radiographic feature? c) Bony outgrowths at joint margins Rationale: Osteophytes form as a reparative response to cartilage damage and joint instability, a key diagnostic criterion for OA.
  2. A patient with hand OA asks about acupuncture. According to Dr. Cole, what is the evidence? b) Small to moderate benefit for pain relief with low risk Rationale: Meta-analyses show acupuncture modestly reduces OA pain compared to sham, but effects may be placebo-influenced.
  3. Dr. Cole’s algorithm for OA recommends restarting acetaminophen at what interval for round-the-clock pain? a) Every 4–6 hours as needed, not to exceed 3000 mg/day Rationale: Acetaminophen has a short half-life; scheduled dosing may be needed for constant pain, but maximum daily dose is strict.
  4. According to Dr. Cole, which finding on history is most suggestive of OA rather than RA? c) Pain that improves with rest and worsens with activity Rationale: OA pain is mechanical; RA pain is inflammatory, with morning stiffness >1 hour and improvement with activity.

Rationale: PRP studies show modest benefit but lack standardization; not covered by insurance; considered experimental.

  1. According to Dr. Cole, which gait training cue reduces knee OA pain during walking? a) “Walk with shorter, quicker steps” Rationale: Shortening stride reduces knee adduction moment and joint loading, decreasing pain in medial compartment OA.
  2. Dr. Cole states that which laboratory test may be elevated in OA due to cartilage breakdown? d) C-telopeptide of type II collagen (CTX-II) Rationale: CTX-II is a biomarker of cartilage degradation, elevated in OA, but not used clinically for diagnosis.
  3. In the WGU D345 curriculum, Dr. Cole identifies which type of shoe as beneficial for knee OA? c) Low-heeled, flexible-soled walking shoes Rationale: Low heels and flexible soles reduce knee torque compared to high heels or overly stiff rocker-bottom shoes.
  4. According to Dr. Cole, which is the most common adverse effect of oral NSAIDs requiring monitoring? b) Dyspepsia and gastrointestinal bleeding Rationale: Dyspepsia occurs in up to 20% of users; serious GI bleeding risk increases with age, dose, and duration.
  1. Dr. Cole’s remediation recommends which treatment for OA-related sleep disturbance? a) Amitriptyline at low bedtime doses Rationale: Low-dose tricyclics improve sleep quality and modulate pain; start 10–25 mg at bedtime, monitor for anticholinergic effects.
  2. A patient with bilateral hip OA asks about cane use. Which instruction is correct? d) Use two canes or a walker if both hips are symptomatic Rationale: One cane in opposite hand is for unilateral disease; bilateral symptoms require bilateral support to prevent gait asymmetry.
  3. According to Dr. Cole, which dietary pattern is anti-inflammatory and may benefit OA? c) Mediterranean diet Rationale: Mediterranean diet (olive oil, fish, nuts, fruits, vegetables) reduces inflammatory markers; may improve OA symptoms.
  4. Dr. Cole’s D345 study guide states that which finding on history suggests secondary OA? b) Prior knee fracture or meniscectomy Rationale: Secondary OA results from previous joint injury, congenital deformity, or metabolic disease; primary OA has no clear cause.
  5. In the remediation, Dr. Cole notes that which pain descriptor is atypical for OA? d) “My joint feels hot and red”

b) Pain diary with activity correlation Rationale: Tracking pain patterns helps identify aggravating activities and guides pacing strategies for daily living.

  1. In the WGU D345 guide, Dr. Cole states that which class of medication may accelerate OA progression? a) Fluoroquinolone antibiotics Rationale: Fluoroquinolones can cause tendinopathy and cartilage damage, especially in weight-bearing joints; use cautiously in OA patients.
  2. According to Dr. Cole, which is the strongest modifiable risk factor for knee OA? c) Obesity Rationale: Obesity increases both mechanical load and systemic inflammation; weight loss is the single most effective modifiable intervention.
  3. Dr. Cole’s algorithm for OA recommends referral to physical therapy for which primary reason? b) To teach quadriceps strengthening and gait retraining Rationale: Quadriceps weakness is common in knee OA; strengthening improves stability and reduces joint load.
  4. A patient with hand OA asks about paraffin wax therapy. According to Dr. Cole, what is its benefit? d) Temporary relief of stiffness and pain

Rationale: Paraffin wax provides superficial heat, temporarily reducing stiffness and pain; no long-term disease modification.

  1. Dr. Cole teaches that which radiographic finding is associated with OA severity? a) Subchondral cysts Rationale: Subchondral cysts form from synovial fluid intrusion into bone; correlate with more advanced OA.
  2. In the D345 remediation, which patient is at highest risk for NSAID- induced GI bleeding? c) Age >65 with prior ulcer history and taking aspirin Rationale: Multiple risk factors (age, prior ulcer, aspirin, anticoagulants) exponentially increase GI bleed risk.
  3. According to Dr. Cole, what is the mechanism of duloxetine in OA pain? b) Inhibition of serotonin and norepinephrine reuptake in the CNS Rationale: Duloxetine enhances descending inhibitory pain pathways in the brain and spinal cord, reducing pain perception.
  4. Dr. Cole’s comprehensive study guide lists which finding as an indication for joint aspiration? d) Sudden onset of a hot, swollen joint Rationale: Acute monoarthritis requires aspiration to rule out septic arthritis or crystal arthropathy (gout, pseudogout).

d) Heat before activity, ice after activity Rationale: Heat increases blood flow and reduces stiffness for warm-up; ice reduces post-activity inflammation and pain.

  1. A patient with OA asks if running worsens knee OA. What does Dr. Cole advise? b) Recreational running does not increase OA risk in healthy knees Rationale: Moderate running does not cause OA; elite or high-mileage running with prior injury may increase risk.
  2. According to Dr. Cole, which finding differentiates OA pseudogout from OA alone? c) Acute swelling with chondrocalcinosis on X-ray Rationale: Pseudogout (calcium pyrophosphate deposition) causes acute flares and linear calcification in cartilage on X-ray.
  3. Dr. Cole’s remediation for D345 states that which biomarker predicts rapid OA progression? a) High serum levels of matrix metalloproteinase-3 (MMP-3) Rationale: Elevated MMP-3 indicates active cartilage breakdown; associated with faster joint space narrowing.
  4. In the comprehensive study guide, Dr. Cole recommends which type of shoe for hip OA? d) Low-heeled shoes with firm heel counter Rationale: Firm heel counter stabilizes the calcaneus, reducing proximal joint torque and hip pain during gait.
  1. According to Dr. Cole, which is a contraindication to total hip arthroplasty? b) Active systemic infection or osteomyelitis Rationale: Active infection poses high risk of prosthetic joint infection; surgery delayed until infection cleared.
  2. Dr. Cole’s algorithm for OA includes which tricyclic antidepressant for chronic pain? c) Nortriptyline Rationale: Nortriptyline has fewer anticholinergic side effects than amitriptyline; started at 10–25 mg at bedtime.
  3. A patient with OA and depression may have improved pain control with which medication class? a) SNRIs (duloxetine or venlafaxine) Rationale: SNRIs treat both depression and chronic OA pain through central pain modulation.
  4. According to Dr. Cole, what is the most accurate statement regarding glucosamine and chondroitin? d) No consistent evidence that they rebuild cartilage Rationale: Large trials show no structural benefit; mild symptom relief possible but not disease modification.
  5. Dr. Cole’s remediation for D345 lists which physical finding in hip OA? b) Decreased internal rotation and flexion
