#1
Which type of wound involves tearing of the skin and underlying tissues?
Laceration
ExplanationLaceration involves tearing of skin and underlying tissues.
#2
What is the primary purpose of the inflammatory phase in wound healing?
Remove debris and bacteria
ExplanationThe inflammatory phase removes debris and bacteria from the wound site.
#3
Which type of wound healing occurs when the wound edges are brought together with minimal tissue loss?
Primary intention
ExplanationPrimary intention healing occurs when wound edges are closely approximated with minimal tissue loss.
#4
Which type of collagen is primarily responsible for providing tensile strength to the wound during the maturation phase of healing?
Collagen Type I
ExplanationCollagen Type I provides tensile strength to the wound during the maturation phase.
#5
Which phase of wound healing involves the removal of necrotic tissue and debris from the wound?
Inflammatory phase
ExplanationThe inflammatory phase involves the removal of necrotic tissue and debris from the wound.
#6
What is the primary function of platelets in the wound healing process?
Form a temporary seal
ExplanationPlatelets form a temporary seal to stop bleeding and initiate clotting.
#7
During which phase of wound healing does angiogenesis occur?
Proliferative phase
ExplanationAngiogenesis occurs during the proliferative phase.
#8
Which type of wound is characterized by a clean and straight cut?
Incision
ExplanationAn incision is characterized by a clean and straight cut.
#9
What is the role of fibroblasts in the wound healing process?
Produce collagen
ExplanationFibroblasts produce collagen during wound healing.
#10
During the maturation phase of wound healing, what happens to the collagen fibers?
They become more organized and cross-linked
ExplanationCollagen fibers become more organized and cross-linked during the maturation phase.
#11
What is a keloid in the context of wound healing?
Excessive scar tissue
ExplanationA keloid is an overgrowth of scar tissue.
#12
Which vitamin is essential for collagen synthesis during wound healing?
Vitamin C
ExplanationVitamin C is essential for collagen synthesis.
#13
In which phase of wound healing does the wound contract and reduce in size?
Maturation phase
ExplanationThe wound contracts and reduces in size during the maturation phase.
#14
What is the primary function of myofibroblasts in wound healing?
Produce collagen
ExplanationMyofibroblasts produce collagen and contract the wound.
#15
Which growth factor plays a crucial role in promoting cell migration and tissue repair during wound healing?
Platelet-derived growth factor (PDGF)
ExplanationPDGF plays a crucial role in promoting cell migration and tissue repair.
