DPT Clinical Reasoning & Decision Making 2 — Questions and Answers
Question 1: A 58-year-old patient with chronic low back pain presents with new-onset saddle anesthesia and urinary retention. What is the MOST appropriate immediate action?
- Refer immediately to emergency services for suspected cauda equina syndrome (Correct answer)
- Order lumbar MRI and follow up in 48 hours
- Begin lumbar traction and reassess in one week
- Apply TENS and schedule physical therapy three times per week
Correct answer: Refer immediately to emergency services for suspected cauda equina syndrome
Saddle anesthesia with urinary retention are red flags for cauda equina syndrome, a surgical emergency requiring immediate referral.
Question 2: During clinical reasoning, which framework helps a PT prioritize impairments that are MOST likely to be contributing to a patient's activity limitations?
- International Classification of Functioning (ICF) model
- Nagi disablement model
- Hypothetico-deductive reasoning model (Correct answer)
- Cognitive continuum theory
Correct answer: Hypothetico-deductive reasoning model
The hypothetico-deductive model guides clinicians to generate and test hypotheses about which impairments most directly drive functional limitations.
Question 3: A patient recovering from a total knee arthroplasty plateaus at 95° knee flexion at week 6. What reasoning process should the PT use FIRST?
- Identify potential contributing factors such as pain, swelling, or scar tissue before changing treatment (Correct answer)
- Immediately escalate to aggressive joint mobilization grade IV
- Discharge the patient because progress has stalled
- Refer back to the surgeon without further assessment
Correct answer: Identify potential contributing factors such as pain, swelling, or scar tissue before changing treatment
Identifying contributing factors (pain, edema, soft tissue restriction) guides targeted intervention rather than blindly escalating intensity.
Question 4: Which reasoning strategy is BEST demonstrated when a PT considers the possibility of cardiac pathology in a patient presenting with left shoulder and arm pain during exercise?
- Pattern recognition with red flag screening (Correct answer)
- Procedural reasoning for exercise selection
- Narrative reasoning for patient values
- Collaborative reasoning with the patient
Correct answer: Pattern recognition with red flag screening
Recognizing the pattern of referred cardiac pain and screening for red flags reflects pattern recognition combined with safety screening.
Question 5: A PT is treating a patient post-stroke with aphasia. The patient appears uncomfortable but cannot verbally communicate pain. What clinical reasoning approach is MOST appropriate?
- Use behavioral pain scales and observe nonverbal cues to assess pain (Correct answer)
- Assume no pain since the patient is not reporting it verbally
- Withhold pain assessment until the patient can communicate verbally
- Ask the caregiver to confirm pain level without directly observing the patient
Correct answer: Use behavioral pain scales and observe nonverbal cues to assess pain
Behavioral pain scales (e.g., PAINAD) and nonverbal observation are validated methods for assessing pain in patients with communication impairments.
Question 6: A PT identifies that a patient has fear-avoidance beliefs strongly contributing to chronic low back disability. Which reasoning domain does this BEST represent?
- Psychosocial reasoning addressing yellow flags (Correct answer)
- Biomedical reasoning addressing structural pathology
- Ethical reasoning about patient autonomy
- Prognostic reasoning about tissue healing
Correct answer: Psychosocial reasoning addressing yellow flags
Fear-avoidance beliefs are yellow flags (psychosocial barriers) that require psychosocial reasoning and targeted behavioral interventions.
Question 7: When applying clinical prediction rules (CPRs), what is the MOST important consideration for a PT using one in clinical practice?
- Validate that the CPR was derived and validated in a population similar to the current patient (Correct answer)
- Apply the CPR regardless of the patient population since all CPRs are universally applicable
- Use CPRs only for surgical referral decisions
- Ignore CPRs since clinical intuition is superior to statistical models
Correct answer: Validate that the CPR was derived and validated in a population similar to the current patient
CPRs should only be applied when the patient matches the derivation and validation population to ensure predictive accuracy.
