wound

a break in the continuity of an external or internal surface caused by physical means

incision

a clean cut caused by a cutting instrument

abscess

a collection of pus in a cavity surrounded by inflamed tissue

what occurs during the inflammatory phase of wound healing?

a fibrin network forms, resulting in a blood clot that "plugs" up the opening of the wound and stops the flow of blood - eventually becomes a scab

colopscope

a lighted instrument with a binocular magnifying lens used to examine the vagina and cervix

furuncle

a localized staphylococcal infection that originates deep within a hair follicle; also known as a boil

serosanguineous

has an opening placed right over the operative site; it covers a wide area of skin around the operative site, leaving only the operative site exposed.

what is the purpose of performing a cervical punch biopsy?

helps physician determine the type of abnormal tissue present on the cervix so that the physician can determine the best form of treatment

what is the difference in function between mosquito hemostatic forceps and standard hemostatic forceps?

hemostatic have serrated tips, ratchets, ring handles and box locks; mosquito forceps have small, fine tips and are more smaller and delicate.

list reasons for the removal of a sebaceous cyst

if they become infected; to relieve discomfort in an area that is easily irritated (armpit)

infiltration~ produces a loss of sensation in an area to prevent patient from feeling pain during the surgery

why should the MA be careful when applying an elastic bandage

it is easy to apply it too tightly and impede circulation

what is the purpose of adding epinephrine to a local anesthetic?

it prolongs the local effect of the anesthetic; decreases the rate of absorption

what is the purpose of using gauze packing or rubber Penrose drain after incising a localized infection?

keeps the edges of the tissues apart; this facilitates drainage of the exudate

larger than normal mole with an irregular color and shape; center is raised and darkened; they are more likely than ordinary moles to develop into malignant melanoma

what are the disadvantages of skin closure tape?

less precise in bringing wound edges together; difficulty adhering to skin (palms, feet, hairy areas)

list the post-op instructions that may be relayed to the patient after a cervical punch biopsy

minimum cramping/ bleeding may occur for about 1 week (call if it lasts longer); thick, dark-colored vaginal discharge may occur; don't douche, use tampons, have intercourse for 1 week after (cervix needs time to heal); contact dr. if anything is wrong

list the post-op instructions that must be relayed to the patient after cervical cryosurgery

normal activities can be performed that day; on first day, a clear watery discharge occurs ( for 2-4 weeks); use pads not tampons for discharge; don't douche, use tampons, have sex

list 4 guidelines to follow when applying a bandage

observe medical asepsis; area is clean and dry; don't apply bandage over an open wound (first apply a dressing); ensure joints and bone prominences are padded correctly to avoid irritation

what is an ingrown toenail?

occurs when the edge of the toenail grows deeply into the nail groove and penetrates the surrounding skin, resulting in pain and discomfort

list 2 reasons for performing a colposcopy?

performed after abnormal pap test results and to evaluate a vaginal or cervical lesions observed during a pelvic exam

where do sebaceous cysts most frequently occur? where do they not occur?

scalp, face, neck, ears, back and genital area; don't occur~ palms of hands and soles of feet (no oil glands)

what are the most common methods used to remove moles?

shave excision, surgical excision, and laser surgery

list 5 examples of materials used for nonabsorbable sutures

what is the purpose of preparing the patient's skin before MOS?

skin contains abundance of microorganisms; a wound infection could develop

small, painless benign growths that project from the skin from a small narrow stalk (peduncle)~ found where skin creases; eyelids, neck, armpits, chest and groin

list 2 advantages of using surgical skin staples to approximate a wound

stapling is a faster method of closure; trauma to the tissue is reduced because the tissue doesn't have to be handled as much

what is a swaged needle? list advantages of using a swaged needle.

suture and needle are one continuous unit; suture material doesn't slip off needle; tissue trauma is reduced because there's only one strand being pulled through

absorbable suture

approximation

the process of bringing two parts, such as tissue, together through the use of sutures or other means

biopsy

the surgical removal and examination of tissue from the living body

cryosurgery

the therapeutic use of freezing temperatures to destroy abnormal tissue

what occurs during the proliferative phase of wound healing?

the wound is rebuilt with new connective tissue (granulation tissue)- fills the wound and protects the surface of the wound

what types of wounds are tissue adhesives most commonly used to close?

they are best suited to close a small superficial lacerations; incisions of face, torso, limbs.

what is the purpose of serrations found on some instruments

they are saw like teeth that grasp tissue and prevent it from slipping out of the jaws of the instrument

how do tissue adhesives work?

they form a strong transparent flexible bond across the top of the skin that binds the skin edges together

why are sutures inserted in the head and neck generally removed sooner than other sutures?

they have a good blood supply; the sutures don't need to be there as long as other areas because they heal more rapidly

what is a sebaceous cyst and what causes it to form?

thin, closed sac located just under the skin; it forms when the outlet of a sebaceous (oil) gland becomes obstructed

list 3 causes of an ingrown toenail

tight shoes/ trauma, improper nail trimming, or infection can cause an ingrown toenail

what is the purpose of wound closure?

to approximate (bring together) the edges of the wound and hold them in place until enough healing has taken place

contaminate

to cause a sterile object or surface to become unsterile

what is the purpose of inflammation?

to destroy invading microorganisms and remove damaged tissue debris from the area

what is the function of an exudate?

to flush foreign debris and dead tissue from the wound and to provide a moist environment to assist in wound healing

what are the functions of a sterile dressing?

to protect the wound from contamination and trauma; to absorb drainage, and restrict motion, which may interfere with proper wound healing

what is the appearance of granulation tissue?

translucent red and dark; soft and moist to touch; bumpy/granular in appearance; painless.
