Multiple Choice Quiz Questions On Wound Healing
Do you know about the wound-healing process? If yes, check out this multiple-choice quiz on wound healing and assess your knowledge. When you accidentally cut yourself shaving or drop a glass and nick yourself trying to clean it up, you may be surprised by how fast the cut seems to quell the bleeding without you having to do much to help that process. What is actually going on here? It is due to wound healing, which simply means healing of the skin. Take this quiz to learn more about this process.
Questions and Answers

What is one vasoactive substance involved with the coagulation phase of tissue repair that causes vasoconstriction and vasodilation?
- A.
Prokinin
- B.
Histamine
- C.
Bradykinin
- D.
Serotonin
Correct Answer
D. SerotoninExplanation
Serotonin is a vasoactive substance involved in the coagulation phase of tissue repair that causes both vasoconstriction and vasodilation. It is released from platelets and acts on blood vessels to constrict them, reducing blood flow and preventing excessive bleeding. However, serotonin can also cause vasodilation in certain tissues, allowing increased blood flow to promote healing and repair. This dual action of serotonin makes it an important player in the regulation of blood vessel diameter during tissue repair.Rate this question:

Name the 4 phases of tissue repair according to Bailey’s.
- A.
Inflammatory, coagulation, fibroplasia, remodeling
- B.
Coagulation, inflammatory, fibroplasia, remodeling
- C.
Coagulation, inflammatory, remodeling, fibroplasia
- D.
Inflammatory, coagulation, remodeling, fibroplasia
Correct Answer
B. Coagulation, inflammatory, fibroplasia, remodelingExplanation
The correct answer is Coagulation, inflammatory, fibroplasia, and remodeling. This sequence of phases represents the process of tissue repair, according to Bailey's. The coagulation phase involves the formation of a blood clot to control bleeding. The inflammatory phase involves the recruitment of immune cells and the release of inflammatory mediators to remove debris and prevent infection. The fibroplasia phase involves the production of new collagen and the formation of granulation tissue. The remodeling phase involves the reorganization and maturation of the new tissue to restore its strength and function.Rate this question:

During the fibroplasia phase, fibroblasts migrate into the wound after how many hours?
- A.
12-24
- B.
24-48
- C.
48-72
- D.
1 week
Correct Answer
C. 48-72Explanation
During the fibroplasia phase, fibroblasts migrate into the wound after 48-72 hours. This phase is characterized by the migration and proliferation of fibroblasts, which are responsible for producing collagen and other extracellular matrix components. Fibroblasts play a crucial role in wound healing by forming a connective tissue matrix that helps to close the wound and promote tissue repair. The migration of fibroblasts typically occurs within the first few days after injury, which is why the correct answer is 48-72 hours.Rate this question:

The role of collagen is
- A.
Cell adhesion
- B.
Locomotion
- C.
Expansion and contraction
- D.
Strength and support
Correct Answer
D. Strength and supportExplanation
Collagen is a protein that provides strength and support to various tissues in the body. It forms a structural framework for cells, organs, and tissues, giving them stability and integrity. Collagen helps in maintaining the shape and structure of tissues, such as skin, tendons, ligaments, and bones. It also contributes to the elasticity and flexibility of these tissues. Therefore, the role of collagen is primarily to provide strength and support to the body.Rate this question:

What is the maximum strength of a scar versus the unwounded skin?
- A.
60%
- B.
80%
- C.
25%
- D.
90%
Correct Answer
B. 80%Explanation
The maximum strength of a scar is 80% compared to unwounded skin. This means that scars are generally weaker and less durable than normal skin, as they only possess 80% of the strength of unwounded skin.Rate this question:

Rate the level of contraction from most to least
- A.
STSG-FTSG-Flap
- B.
Flap-STSG-FTSG
- C.
Flap-FTSG-STSG
- D.
FTSG-Flap-STSG
Correct Answer
A. STSG-FTSG-FlapExplanation
The correct answer is STSG-FTSG-Flap. This order represents the level of contraction from most to least. STSG (Split-thickness skin graft) involves removing the top layers of skin and placing it on a wound, resulting in the highest level of contraction. FTSG (Full-thickness skin graft) involves removing all layers of skin and placing it on a wound, resulting in less contraction compared to STSG. Flap involves transferring tissue from one area of the body to another, resulting in the least amount of contraction.Rate this question:

Intact dermis contains how much Type I collagen and how much Type IIIcollagen?
- A.
50%/50%
- B.
60%/40%
- C.
80%/20%
- D.
25%/75%
Correct Answer
C. 80%/20%Explanation
The correct answer is 80%/20%. The dermis is composed mainly of collagen, with type I collagen being the most abundant and type III collagen being present in smaller amounts. In intact dermis, approximately 80% of the collagen is type I collagen, while only around 20% is type III collagen.Rate this question:

What is needed for collagen synthesis?
- A.
Vitamin C
- B.
Supplements
- C.
Proteins
- D.
All of the above
Correct Answer
A. Vitamin CExplanation
Vitamin C is needed for collagen synthesis. Collagen is a protein that helps in maintaining the structure and elasticity of various tissues in the body. Vitamin C plays a crucial role in the synthesis of collagen by acting as a cofactor for the enzymes involved in collagen production. Without sufficient vitamin C, the body is unable to produce collagen effectively, leading to various health issues such as weakened connective tissues, impaired wound healing, and increased susceptibility to infections. Therefore, vitamin C is essential for collagen synthesis.Rate this question:

The optimal time to operate on irradiated tissue is
- A.
Between 6 weeks and 6 months
- B.
Between 3 weeks and 3 months
- C.
Between 6 months and 1 year
- D.
Between 4 weeks and 6 months
Correct Answer
B. Between 3 weeks and 3 monthsExplanation
The optimal time to operate on irradiated tissue is between 3 weeks and 3 months. This is because during this time frame, the tissue has had enough time to heal and recover from the effects of radiation, but it is not too long that the tissue becomes too fibrotic and difficult to operate on. Operating within this window allows for the best chances of successful surgery and optimal outcomes for the patient.Rate this question:

A patient on chronic prednisone therapy for rheumatoid arthritis, administration of what agent may mitigate the detrimental effects on wound healing?
- A.
Vitamin C
- B.
Vitamin E
- C.
Vitamin A
- D.
Zinc
Correct Answer
C. Vitamin AExplanation
Vitamin A may mitigate the detrimental effects of chronic prednisone therapy on wound healing. Vitamin A is known to play a crucial role in the process of wound healing by promoting cell growth, collagen synthesis, and immune function. Chronic prednisone therapy can impair wound healing due to its immunosuppressive effects. Therefore, supplementing with vitamin A can help counteract these effects and improve wound healing in patients on prednisone therapy for rheumatoid arthritis.Rate this question:
