Category 1
The most common site of initial gout attack is:
A. Knee
B. Wrist
C. First metatarsophalangeal joint
D. Shoulder
First metatarsophalangeal joint
(Big toe joint)
A hot, swollen joint with limited passive range of motion should be treated as:
A. Degenerative disease
B. Infectious process
C. Autoimmune flare
D. Neuropathic pain
Infectious process
Why: Hot joint + pain with passive ROM = septic arthritis until proven otherwise.
Primary EMS priority in suspected septic arthritis?
A. Splinting
B. Ice
C. Rapid transport and sepsis monitoring
D. Encourage ambulation
Rapid transport and sepsis monitoring
Why: Septic arthritis can progress to systemic sepsis.
EMS role: IV access, monitor perfusion, early transport.
Which symptom is most concerning for spinal cord compression?
A. Local tenderness
B. Radiating pain
C. Urinary retention
D. Pain with movement
Urinary retention
Why: Suggests spinal cord or cauda equina compression
Which lab abnormality is associated with gout?
A. Elevated glucose
B. Elevated uric acid
C. Elevated potassium
D. Elevated calcium
Elevated uric acid
Why: Hyperuricemia leads to urate crystal deposition in gout.
Gout is caused by:
A. Autoimmune synovial destruction
B. Degenerative cartilage loss
C. Uric acid crystal deposition
D. Bacterial invasion
Uric acid crystal deposition
Why: Monosodium urate crystals deposit in joints → intense inflammatory response.
Ankylosing spondylitis increases risk for:
A. Rib fractures
B. Cervical spine fractures
C. Hip dislocation
D. Pelvic instability
Cervical spine fractures
Why: Ankylosing spondylitis causes rigid, brittle spine (“bamboo spine”) → prone to fracture with minor trauma.
Osteoarthritis primarily affects:
A. Synovial membrane
B. Cartilage
C. Bone marrow
D. Ligaments
Cartilage
Why: OA primarily affects articular cartilage → joint space narrowing → osteophytes
Which medication class contributes significantly to osteoporosis?
A. Beta blockers
B. Corticosteroids
C. ACE inhibitors
D. SSRIs
Corticosteroids
Why: Chronic steroid use inhibits osteoblast activity → accelerated bone loss → osteoporosis.
Which finding would make septic arthritis more likely than osteoarthritis?
A. Chronic stiffness
B. Pain worse at end of day
C. Fever and acute onset
D. Crepitus
Fever and acute onset
Why: Septic arthritis = infection of synovial membrane → systemic signs (fever, tachycardia).
OA does not produce systemic symptoms.
A 72-year-old male complains of severe lower back pain that began suddenly while watching TV. He denies trauma. He describes the pain as “deep” and “tearing.”
Assessment:
What condition must you suspect FIRST?
A. Lumbar strain
B. Herniated disc
C. Spinal metastasis
D. Abdominal aortic aneurysm rupture
Abdominal aortic aneurysm rupture
AAA rupture → retroperitoneal hemorrhage → hypovolemic shock.
Key clues:
Musculoskeletal causes do NOT cause shock.
A 76-year-old female with chronic knee pain reports gradual worsening over years. Pain worsens with activity and improves with rest. No systemic symptoms.
Most likely diagnosis?
A. Rheumatoid arthritis
B. Septic arthritis
C. Osteoarthritis
D. Gout
Osteoarthritis
Why: Degenerative cartilage breakdown → pain worse with use, improves with rest.
Not RA: RA is inflammatory and often symmetric with prolonged morning stiffness
A 56-year-old female with severe rheumatoid arthritis presents after minor MVC with neck pain and bilateral hand tingling.
Why is this patient at high risk for spinal cord injury?
A. Bone spurs compress nerves
B. Ligamentous instability at C1-C2
C. Vertebral osteoporosis
D. Muscle atrophy
Ligamentous instability at C1-C2
RA causes:
Even minor trauma may cause:
In elderly patients, minimal trauma can cause fractures due to:
A. Increased bone density
B. Cartilage overgrowth
C. Decreased bone mineral density
D. Ligament hypertrophy
Decreased bone mineral density
Why: Osteoporosis weakens structural integrity → fractures with minimal trauma.
Which finding requires immediate transport in a back pain patient?
A. Pain with movement
B. Age over 65
C. History of malignancy with neurologic deficit
D. Chronic stiffness
History of malignancy with neurologic deficit
Why: Suggests metastatic spinal cord compression → immediate transport required.
A 64-year-old male presents with a swollen, painful left knee. He reports gradual onset over 3 days. He has diabetes. Today he feels weak and feverish.
Assessment:
What is your MOST concerning diagnosis?
A. Gout
B. Osteoarthritis flare
C. Septic arthritis
D. Cellulitis
Septic arthritis
Septic arthritis occurs when bacteria invade the synovial space → rapid inflammation → cartilage destruction → possible bacteremia.
Risk factors:
Key clues:
Passive ROM pain strongly suggests intra-articular pathology.
An 82-year-old male with osteoporosis develops acute lumbar pain after coughing.
Most likely cause?
A. Disc herniation
B. Compression fracture
C. Muscle spasm
D. Renal colic
Compression fracture
Why: Osteoporosis decreases bone mineral density → minimal stress (coughing) causes vertebral collapse.
Disc herniation usually produces radicular symptoms.
You respond to a 75-year-old female with severe right hip pain. She denies falling but reports she “twisted wrong” while getting out of bed. She has a history of rheumatoid arthritis and has been on long-term prednisone therapy.
Assessment:
What is the MOST likely cause of her presentation?
A. Hip dislocation
B. Muscular strain
C. Pathologic hip fracture
D. Sciatic nerve impingement
Pathologic hip fracture
Chronic corticosteroid use:
RA also contributes to bone weakening.
A “low-mechanism” injury causing:
Is classic for proximal femur (hip) fracture, even without a fall.
A 42-year-old male presents with years of back stiffness that improves with activity and worsens with rest. Progressive loss of spinal flexibility noted.
Which disorder best explains this presentation?
A. Osteoarthritis
B. Ankylosing spondylitis
C. Lumbar strain
D. Degenerative disc disease
Ankylosing spondylitis:
A 70-year-old male with sudden back pain, hypotension, and tachycardia should raise concern for:
A. Lumbar strain
B. Spinal stenosis
C. Abdominal aortic aneurysm
D. Sciatica
Abdominal aortic aneurysm
Why: Back pain + hypotension + tachycardia = vascular emergency.
A 68-year-old female with history of breast cancer presents with:
What serious etiology must be suspected?
A. Lumbar strain
B. Sciatica
C. Spinal metastasis
D. Osteoarthritis
Spinal metastasis
Red flags here:
Septic arthritis involves bacterial invasion of the synovial membrane → rapid inflammation → joint destruction → sepsis risk.
A 73-year-old female taking alendronate (Fosamax) "Osteoporosis medication" reports chest pain and painful swallowing after taking her medication while lying down.
What complication is most likely?
A. Myocardial infarction
B. Esophageal ulceration
C. Pulmonary embolism
D. Rib fracture
Esophageal ulceration
Bisphosphonates:
An 80-year-old male with osteoporosis and chronic steroid use develops sudden thoracic back pain after lifting groceries. No trauma.
Vitals stable. Pain increases with movement. No neuro deficits.
What pathologic process is most consistent?
A. Disc herniation
B. Vertebral compression fracture
C. Muscular strain
D. Spinal infection
Vertebral Compression Fraction.
Compression fractures commonly occur in:
A 59-year-old male presents with sudden severe pain in the first metatarsophalangeal joint. It is red, hot, and exquisitely tender. He drank alcohol last night.
Temp 99.5°F.
What is the most likely pathophysiologic process?
A. Bacterial soft tissue infection
B. Uric acid crystal deposition
C. Degenerative cartilage breakdown
D. Autoimmune synovial attack
Uric acid crystal deposition.
Gout results from:
Classic features:
You are dispatched for a 66-year-old male complaining of worsening lower back pain for one week. He reports the pain now radiates down both legs. Today he noticed difficulty urinating and feels "numb" in his inner thighs.
What is the most likely diagnosis?
A. Lumbar muscle strain
B. Sciatica
C. Cauda equina syndrome
D. Osteoarthritis
Cauda equina syndrome
Cauda equina syndrome occurs when the nerve roots below the spinal cord (L2–S5) become compressed, commonly from:
Compression of these nerve roots leads to:
The “saddle anesthesia” is the critical clue here.
Key Red Flags in This Scenario
Bilateral symptoms (not unilateral)
Urinary retention
Perineal numbness
Progressive neurologic deficit
These findings indicate neurologic emergency, not routine back pain.
Why the Other Answers Are Wrong
A. Lumbar muscle strain
B. Sciatica
D. Osteoarthritis
