What is the mechanism on a clamp that interlocks to keep the instrument closed?
Ratchet
Which type of scalpel is curved outward, and is used for growth removals?
Convex
Which type of scalpel is pointed inward and is used for delicate tissue?
Concave
Two-pronged instrument for grasping or holding body tissue, foreign bodies, or surgical materials?
Forceps
Instruments used to hold back the edges of a wound or incision to expose the operative area?
Retractors
Long-handled instruments with a metal loop on one end used for scrapping the inside of a cavity.
Inner side of the loop is sharp to scrape, outer edge is dull to protect against unwanted tissue damage. Can also be smooth on the inner and outer edges to allow scrapping without cutting tissue)
Curette
5 major steps when pouring a sterile solution?
1. Sanitize hands
2. Read the label- verify correct solution and verify expo date.
3. Palm the label of the bottle.
4. Pour solution.
5. Replace the cap on the bottle.
How many times would you check the label before pouring a solution? And when would you do this?
3 times, same as medications. Once when removing solution from storage, once when the bottle is opened, and once again when putting the solution away.
What produces unconsciousness by depressing the central nervous system (CNS)
General anesthetics
4 attributes the healing process depends on?
1. General state of patient's health.
2. Good nutrition.
3. Adequate blood supply w/ normal clotting.
4. Use of proper aseptic technique during surgery and dressing changes.
Does the healing process depend partly on how far the injury is away from the heart?
No.
Type of wound that is jagged, irregular break or tear of tissue, usually caused by blunt trauma?
Laceration
A superficial wound; skin scrape?
Abrasion
Type of healing that occurs when a clean surgical wound is closed and heals with minimal scarring and no infection?
"Primary" first intention healing
Type of healing that occurs when a large wound is not closed and heals from the bottom up; a large amount of scarring occurs.
"Secondary" second intention healing
Type of healing that occurs when the wound is left open because of infection or debris. Typically requires debridement and may be sutured.
"Tertiary" delayed primary intention healing
Material term used for suturing, although often used with synthetics nowadays.
Catgut
Catgut sutures are used in what kind of tissue?
Tissue that heals rapidly and when absorption of suture material is desired.
T/F: Untreated materials for suturing such as nylon, silk, stainless steel, and polypropylene absorb into the tisse?
False
What does a physician base his suture size selection on when closing a wound?
Amount of healing time required
Site of the wound
Strength of suture needed to close it
Surgical 1 silk is what in diameter?
Thickest and largest
What type of needle cuts tissues?
Sharp point (cutting) needle
What type of needle separates tissues?
Round pointed (tapered) needle
Wound closures that are long, narrow adhesive strips that are used to close small wound areas instead of sutures?
Skin closures
T/F: skin closures are stronger than sutures?
False
Why would you cut the sutures at skin level when removing sutures?
Suture material has been exposed to contamination during the healing process, this prevents it from being pulled through the skin.
Why use dressing forceps to lift the suture straight upward, toward the suture line during suture removals?
Pulling straight up prevents tugging against the tissue, and minimized the possibility of reopening the suture line.
