What protective mechanisms are impaired or deficient in the abraded areas? Assuming that bacteria are penetrating the dermis in these areas, what remaining skin defenses might act to prevent further bacterial invasion? What benefit is conferred by suturing the lacerations? Mrs. X's cyanotic skin may hint at what additional problem and impairment of what body systems or functions?
