Total questions: 75
Worksheet time: 38mins
Which of the following best describes primary intention in wound healing?
Wound is made surgically with little tissue loss and skin edges are close together.
Wound is left open to heal naturally with significant tissue loss.
Wound is infected and requires antibiotics for healing.
Wound is closed with staples after a long delay.
What is a characteristic result of primary intention wound healing?
Significant scarring
Minimal scarring
No scarring at all
Excessive bleeding
During which phase of healing does primary intention begin?
Proliferative phase
Maturation phase
Inflammatory phase
Remodeling phase
Why are skin edges close together in primary intention wound healing?
To allow for more tissue loss
To promote minimal scarring and faster healing
To increase the risk of infection
To delay the healing process
What is a characteristic of secondary intention wound healing?
Healing occurs when skin edges are not close together or when pus has formed.
Healing occurs when skin edges are tightly closed.
Healing occurs without the formation of granulation tissue.
Healing occurs only in the absence of infection.
During secondary intention wound healing, what does the surgeon do if the wound has purulent exudates?
Provides a means for its release via drainage system or by packing the wound.
Covers the wound with a sterile bandage only.
Applies antibiotics directly to the wound surface.
Closes the wound with sutures immediately.
Which of the following best describes what happens to necrotized tissue during secondary intention wound healing?
It decomposes and escapes.
It is absorbed into the bloodstream.
It forms a hard scab over the wound.
It remains in the wound and delays healing.
Why is scarring generally greater in wounds that heal by secondary intention?
Because the amount of granulation tissue required depends on the size of the wound.
Because the wound is always infected.
Because the wound is closed with sutures.
Because the wound is exposed to air.
Explain why the cavity of a wound healing by secondary intention begins to fill with granulation tissue, and discuss the implications for wound size and scarring.
Granulation tissue fills the cavity to replace lost tissue, and larger wounds require more granulation tissue, leading to greater scarring.
Granulation tissue prevents infection, and smaller wounds heal faster with less scarring.
Granulation tissue forms only in the presence of pus, and scarring is unrelated to wound size.
Granulation tissue is unnecessary for healing, and scarring is always minimal.
What is the basic process of healing in all wounds?
It is the same in all wounds.
It differs greatly between wounds.
It only occurs in minor wounds.
It is unique to each individual.
Which of the following is true about wounds healing by secondary intention compared to primary intention?
They require less time to close.

They do not form granulation tissue.
Which characteristic is more prominent in wounds healing by secondary intention?
Less granulation tissue is formed.

The wound edges are closer together.

Hypertrophic scars do not expand beyond the wound, while keloids do.
Neither hypertrophic scars nor keloids expand beyond the wound.
