Free CWS Exam Questions That Helps Candidates Pass

Comprehensive and Detailed Explanation:

Re-epithelialization is accomplished by keratinocytes that proliferate at the wound margins and from residual epidermal appendages, then migrate across a moist, viable bed until they meet and restore continuity of the epidermis. Neutrophils clear debris early. Myofibroblasts contribute to contraction but do not re-form the epidermis. Platelet activity belongs to hemostasis. Clinical observation of advancing epithelial edges is a key indicator that the proliferative phase is progressing and that moisture balance and bed preparation are adequate.

Comprehensive and Detailed Explanation:

An ABI in the 0.5–0.8 range indicates moderate peripheral artery disease. In the absence of rest pain or tissue loss at the digits, modified compression is often feasible and local wound care can proceed with careful monitoring for ischemic symptoms. Critical ischemia is typically associated with lower pressures plus rest pain or gangrene. A normal ABI is ≥0.9. The reduced ABI confirms an arterial component, so the wound is mixed rather than pure venous. Accurate stratification protects the patient from both under-treatment of venous hypertension and over-compression of an ischemic limb.
