Question

A large bookcase falls upon an elderly man in his home. His left leg is pinned and he cannot move for 2 days until his neighbor finds him. He is hospitalized with massive trauma to his left leg, with resultant rhabdomyolysis (rhabdomyo means striated muscle tissue; lysis means "break down"). His pulses in that foot are unpalpable and the foot is pale and cool. Eventually his foot must be amputated.

Which mini-concept map, showing one event leading to the next, best fits with the scenario above?
a. Massive mechanical trauma to leg distal arterial flow blocked ischemia to foot infarction of foot tissue amputation.
b. Rhabdomyolysis damage to striated cells spreads to arteries proximal to the trauma
ischemia infection amputation.
c. Mechanical trauma interrupt cell membrane functions such as Na/K pump solute imbalance leg edema amputation.
d. Cool foot tissues become too cold to conduct metabolic pathway functions cells become dormant distal arterial flow increases pathologically amputation.

Answer 1

The mini-concept map that best fits with the scenario is: 'Massive mechanical trauma to leg → distal arterial flow blocked → ischemia to foot → infarction of foot tissue → amputation.'

Step-by-step explanation:

In this scenario, the best mini-concept map that fits is option A, which is: 'Massive mechanical trauma to leg → distal arterial flow blocked → ischemia to foot → infarction of foot tissue → amputation.'
