#1
Which of the following is a key component of the inflammatory phase in wound healing?
Hemostasis
ExplanationInitial stage involving blood vessel constriction to stop bleeding.
#2
What is the primary function of platelets in the wound healing process?
Blood clotting
ExplanationFormation of a clot to prevent excessive bleeding.
#3
Which type of dressing is often used in wounds with moderate to heavy exudate?
Foam
ExplanationAbsorbs excess fluid while maintaining a moist environment.
#4
What is the purpose of using antimicrobial agents in wound care?
To prevent infection
ExplanationKills or inhibits the growth of microorganisms to reduce infection risk.
#5
Which vitamin is essential for collagen synthesis and plays a crucial role in wound healing?
Vitamin C
ExplanationRequired for collagen production and tissue repair.
#6
Which phase of wound healing is characterized by scar maturation and remodeling of collagen fibers?
Maturation phase
ExplanationFinal stage where scar tissue matures and becomes stronger.
#7
Which type of wound closure involves bringing the wound edges together using stitches or staples?
Primary intention
ExplanationDirect closure to promote faster healing and minimal scarring.
#8
What is the optimal moisture level for wound healing?
Moist environment
ExplanationKeeps the wound bed hydrated, facilitating cell migration and proliferation.
#9
Which of the following factors can impair the wound healing process?
Smoking
ExplanationDecreases blood flow and impairs oxygen delivery to tissues.
#10
What is the role of fibroblasts in wound healing?
Collagen synthesis
ExplanationProduces collagen, the main structural protein in connective tissue.
#11
What is the primary function of a hydrogel dressing in wound care?
Maintain moisture
ExplanationKeeps the wound moist, promoting a conducive environment for healing.
#12
Which type of wound closure is associated with delayed healing and increased risk of infection?
Secondary intention
ExplanationHealing by granulation tissue formation, often slower with higher infection risk.
#13
Which growth factor plays a crucial role in stimulating cell proliferation and angiogenesis during wound healing?
Platelet-Derived Growth Factor (PDGF)
ExplanationStimulates cell growth and new blood vessel formation.
#14
Which phase of wound healing involves the restoration of tissue strength and function?
Remodeling phase
ExplanationFinal stage where collagen is remodeled and tissue strength is regained.
#15
In wound care, what does the term 'debridement' refer to?
Removal of dead tissue
ExplanationCleansing of the wound from necrotic or infected tissue.
#16
In wound assessment, what does the term 'granulation tissue' refer to?
New blood vessels and fibroblasts
ExplanationPink/red tissue containing blood vessels and fibroblasts in the wound bed.
#17
Which factor is crucial for proper wound healing but often compromised in individuals with diabetes?
Angiogenesis
ExplanationFormation of new blood vessels, impaired in diabetic patients.
#18
What is the primary goal of negative pressure wound therapy (NPWT) in wound care?
Enhance tissue perfusion
ExplanationImproves blood flow and promotes tissue growth through controlled suction.
