Modalities: Three Clinical Reasoning Checks
These are original short teaching scenarios. Think through the safest next step before revealing the reasoning. They are not scored, and nothing is saved.
Case 1: Heat after an acute ankle injury
A person presents shortly after twisting an ankle. It is swollen and weight bearing is difficult. They ask for a hot pack before any examination.
- A. Use heat because it improves comfort
- B. Check trauma/red flags, neurovascular status and tissue condition before selecting any thermal agent
- C. Apply intense cold for the longest available time
Reveal the best next step
Best answer: B. Safety assessment comes before agent preference. Fracture risk, swelling, skin and circulation, sensation and other signs must be considered. A heat or cold pack does not replace an appropriate injury evaluation.
Case 2: Stimulation and an implanted cardiac device
A patient asks about using home TENS for pain and mentions an implanted cardiac electronic device. They do not know the device type or restrictions.
- A. Provide one universal safe electrode placement
- B. Ignore the implant if the current feels mild
- C. Hold unsupervised use and obtain device-specific guidance through the treating team
Reveal the best next step
Best answer: C. Electromagnetic and current interactions depend on the specific implant and application. The patient needs device-related guidance and clinical screening; a generic assurance is unsafe.
Case 3: Compression and new calf swelling
A person develops new painful swelling in one calf and asks for a tighter compression garment before exercise.
- A. Screen urgently for vascular/systemic concerns and arrange appropriate medical evaluation
- B. Tighten the wrap because swelling is always fluid overload
- C. Add BFR exercise first to stimulate the circulation
Reveal the best next step
Best answer: A. Acute unilateral swelling can indicate serious pathology. Establishing cause and medical safety is more important than choosing compression or BFR.
