DPT Clinical Reasoning & Decision Making 5 — Questions and Answers
Question 1: A PT is selecting between two equally evidence-supported interventions for a patient. The patient strongly prefers one based on personal experience. Using shared decision-making, the PT should:
- Integrate the patient's preference alongside evidence and clinical expertise to collaboratively choose the intervention (Correct answer)
- Override the preference and select the intervention the PT deems superior
- Defer entirely to the patient without providing clinical guidance
- Randomize the choice because both have equal evidence
Correct answer: Integrate the patient's preference alongside evidence and clinical expertise to collaboratively choose the intervention
Shared decision-making integrates best evidence, clinical expertise, and patient values/preferences to reach a mutually agreed-upon plan.
Question 2: A PT notes that a patient's pain increases with lumbar extension and decreases with flexion. This directional preference finding is MOST consistent with which clinical reasoning approach?
- McKenzie Mechanical Diagnosis and Therapy (MDT) classification for centralization and directional preference (Correct answer)
- Myofascial release targeting thoracolumbar fascia
- Neural mobilization for lumbar nerve root impingement
- Stabilization-based reasoning for segmental instability
Correct answer: McKenzie Mechanical Diagnosis and Therapy (MDT) classification for centralization and directional preference
Directional preference with symptom centralization or abolition is the hallmark finding used in McKenzie MDT classification and treatment matching.
Question 3: A PT evaluates a 35-year-old runner with plantar heel pain. Reasoning reveals pain is worst with first steps in the morning and eases with walking. This pattern MOST supports which clinical reasoning conclusion?
- Plantar fasciitis based on characteristic morning stiffness and warm-up phenomenon (Correct answer)
- Calcaneal stress fracture requiring immediate imaging referral
- Tarsal tunnel syndrome based on neural tension signs
- Achilles tendinopathy based on midsubstance tendon pain
Correct answer: Plantar fasciitis based on characteristic morning stiffness and warm-up phenomenon
Morning stiffness that improves with activity is the classic presentation of plantar fasciitis, reflecting tissue creep and inflammatory response to initial loading.
Question 4: In clinical reasoning, what does 'epistemic humility' require a PT to do when encountering an unfamiliar patient presentation?
- Acknowledge the limits of their knowledge and seek consultation or additional resources rather than assuming diagnostic certainty (Correct answer)
- Confidently proceed with the most common diagnosis to avoid treatment delays
- Refer all unfamiliar cases to other disciplines without performing an examination
- Document uncertainty and defer all decision-making to the physician
Correct answer: Acknowledge the limits of their knowledge and seek consultation or additional resources rather than assuming diagnostic certainty
Epistemic humility means recognizing knowledge limitations and actively seeking information or consultation to avoid diagnostic error.
Question 5: A PT is evaluating a patient referred for shoulder impingement. During cervical screening, the Spurling's test reproduces the patient's shoulder symptoms. What clinical reasoning action is MOST appropriate?
- Revise the working hypothesis to include cervical radiculopathy as a contributing or alternative diagnosis (Correct answer)
- Confirm shoulder impingement and proceed with rotator cuff strengthening
- Dismiss the cervical finding as unrelated to the shoulder complaint
- Discharge and refer back to the physician for cervical assessment
Correct answer: Revise the working hypothesis to include cervical radiculopathy as a contributing or alternative diagnosis
A positive Spurling's test reproducing shoulder symptoms shifts the hypothesis toward cervical radiculopathy as a driver of apparent shoulder pain.
Question 6: A PT is determining whether to progress a patient's loading program after ACL reconstruction. Which clinical criterion BEST supports progression from phase 2 to phase 3 (return-to-sport phase)?
- Limb symmetry index ≥90% on quadriceps strength testing and absence of pain or effusion with current activities (Correct answer)
- Completion of six weeks post-surgery regardless of functional testing results
- Patient self-report of readiness without objective performance testing
- Achieving 120° of knee flexion as the sole criterion for advancement
Correct answer: Limb symmetry index ≥90% on quadriceps strength testing and absence of pain or effusion with current activities
Evidence-based ACL progression requires objective criteria including limb symmetry index ≥90% and symptom-free performance to minimize re-tear risk.
Question 7: A PT who routinely prescribes the same protocol for all patients with a given diagnosis WITHOUT individualizing based on examination findings BEST represents which cognitive error?
- Prototyping or routine reasoning bias leading to failure to individualize care (Correct answer)
- Evidence-based practice applied consistently across a patient population
- Efficient use of standardized clinical guidelines
- Appropriate pattern recognition reducing unnecessary examination time
Correct answer: Prototyping or routine reasoning bias leading to failure to individualize care
Applying a fixed protocol without individual examination data is a cognitive bias that ignores patient-specific impairments and leads to suboptimal outcomes.
