KROK 1 2015 – Question 154 · KROK (Medicine) · Pathophysiology
A 25-year-old patient complains of increasing pain in his leg muscles occurring during walking and forcing him to make frequent stops. Objectively: skin of legs is pale, no hair-covering, toenails are with trophic changes, no pulsation of pedal arteries. The most probable cause of these changes is:
- A. Embolism
- B. Ischemia
- C. Arterial hyperemia
- D. Venous hyperemia
- E. -
Hint
Think about how the blood supply of working muscle must rise with exercise, and what pale, hairless skin and absent pedal pulses say about the arterial inflow.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
