QuestionAnswer
what are the two layers of the skin? epidermis and dermis
what is the function of the skin? protection
what are the three pressure-related factors that contribute to pressure ulcer development? pressure intensity, pressure duration, and tissue tolerance
what is pressure intensity? the minimal amount of pressure required to collapse a capillary
what happens for tissue ischemia to occur? the pressure applied over a capillary exceeds the normal capillary pressure and the vessel is occluded for a prolonged period of time
what is hyperemia? redness
what is blanching hyperemia? if the area blanches(turns to lighter color) and the erythema returns when you remove your finger then the hyperemia is transient and is an attempt to over come the ischemia episode
what is probable if area does not blanch? if it doesnt blanch when pressure is applied then deep tissue damage is probable
what are the two considerations when it comes to pressure duration? low pressures over a long period of time cause tissue damage as well as high intensity pressure over a short period of time
what is tissue tolerance? the ability of tissue to endure pressure depends upon the integrity of the tissue and the supporting structures
what are some risk factors for pressure ulcer development? impaired sensory perception, impaired mobility, alteration in consciousness, shear, friction, moisture
what is shearing? the force exerted parallel to skin resulting from both gravity pushing down on the body and resistance
what is friction? the force of two surfaces moving across one another, such as mechanical force exerted when skin is dragged across a coarse surface such as bed linens
why does moisture affect pressure ulcers? the presence and duration of moisture on the skin increases the risk of ulcer formation
what are some intervention activities for pressure ulcers? document skin status daily, monitor redness closly, remove excessive moisture, apply protective barriers, turn every 1 to 2 hours, inspect skin over bony prominences, position pillows to evelvate pressure point off bed, keep linens dry clean and wrinkle f
what is stage one of a pressure ulcer? persistent red, blue, or purple tones; no open skin areas
what is stage two of a pressure ulcer? partial thickness skin loss; presents as an abrasion or blister
what is a stage three pressure ulcer? full-thickness skin loss with damage or necrosis of subcutaneous tissue; presents as deep crater
what is stage four pressure ulcer? full-thickness skil loss with extensive destruction, necrosis, or damage to muscle, bone or other structures
how are pressure ulcers categorized? they are staged, graded, according to the level of tissue damage involved
what is granulated tissue? red moist tissue composed of new blood vessels, the presence of which indicates progression toward healing
what is slough? soft yellow or white tissue
what is eschar? black or brown necrotic tissue which needs to be removed for healing; eschar has to be removed before staging
what is exudate? the amount, color, consistency, and color of wound drainage and is part of wound assessment
what is an acute wound? wound that proceeds through an orderly and timely reparative process that results in sustained restoration of anatomical and functional integrity; caused by trauma or a surgical incisison
what is a chronic wound? wound that fails to proceed through an orderly and timely process to produce anatomical and functional integrity; caused by vascular compromise, chronic inflammation, or repetitive insults to the tissue
what are the steps to wound healing? primary, secondary, and tertiary intention
what is primary intention? a clean surgical incision with little tissue loss will heal by primary intention
what is secondary intention? a wound involving loss of tissue such as a burn, pressure ulcer, or severe laceration heals by secondary intention; the wound is left open until it becomes filled by scar tissue
what is tertiary intention? wound left open for several days, the wound edges are approximated
what is partial thickness wound repair? causes the inflammatory response usually in first 24 hours, the epithelal cells begin to regenerate which is epithelial proliferation and migration, then reestablishment of the epidermal layers starts which is where the cells slowly reestablish normal thi
what is full-thickness wound repair? the steps are inflammatory, proliferative where the wound fills with granulation tissue and contraction occurs and resurfacing starts, and remodeling where collagen fibers undergo remodeling
what are complication with wound healing? hemorrhage, infection, dehiscence, evisceration, and fistula formation
what is hemorrhage? bleading from wound site, is normal during and immediatly after initial trauma
what is hemostasis? occurs withing several minutes unless large blood vessels are involved or the client has poor clotting function
what is a hematoma? is a localized collection of blood underneath the tissues it appears as swelling, change in color, sensation, or warmth or mass that often takes on a bluish discoloration
how do you know if you have wound infection? second most common nosicomial infection that is infected if purulent material drains from it
when does an infection arise? the fourth or fifth postoperative day
what are the signs of infection? fever, tenderness and pain at wound site, and elevated WBC count, the edges of wound appear inflamed drainage is odorous and purulent

what is tissue perfusion? the ability to perfuse the tissues with adequate amounts of oxygenated blood is critical to wound healing
why is infection a factor in wound healing and pressure ulcers? wound infection prolong the inflammatory phase, delays collagen synthesis, prevents epithelialization, and increase the production of proinflammatory cytokines that lead to additional tissue destruction
why is age a factor in wound healing and pressure ulcers? age affects all phases of wound healing; a decrease in the functioning of the macrophage leads to a delayed inflammatory response, delayed collagen synthesis, and slower epithelialization
what are pyschosocial impact of wounds? body image and social resources
what are some nonsurgical management of wounds? dressings, physical therapy, drug therapy, diet therapy, electrical stimulation, vacuum-assisted wound closure, and hyperbaric oxygen therapy
how do dressing help wounds? a proper dressing can speed healing by removing unwanted debris, protect exposed healthy tissue, and create a barrier between boy and environment
what is physical therapy for wounds? the use of daily whirlpool treatments along with dressing changes for debridement
what is drug therapy for wounds? clean, healthy granulation tissue has a blood supply and is capable of providing white blood cells and antibodies to the ulcer surface to combat infection

what are the components of the GI tract? mouth, esophagus, stomach, small intestines, large intestines, anus, defication
what happens in the mouth? the teeth masticate food breaking it down into a size suitable for swallowing; saliva produced by salivary glands in mouth dilute and soften food in the mouth for easier swallowing
what happens in the esophagus? the bolus of food travels down the esophagus and is pushed along by peristalsis which propels food through the length of the GI tract
what are the tasks of the stomach? storing swallowed food and liquid, mixing of food liquid and digestive juices, and emptying contents into the small intestine
what is secreted and produced in the stomach? hydrochloric acid, mucus, the enzyme pepsin, and the intrinsic factor

what is the main activity in the small intestine? absorb most of the nutrients and electrolytes
what is the primary function of the large intestine? bowel elimination
what happens in the rectum? bacteria convert fecal matter into its final form
how does age affect bowel elimination? infant has smaller stomach and less secretion of digestive enzymes, older adults have a decrease in peristalsis and esophageal emptying slows
how does diet affect bowel elimination? regular daily food intake regulates peristalsis fiber helps elimination and gas producing foods stimulate peristalsis
how does fulid intake affect bowel elimination? inadequate fluid intake affect the character of feces; reducing fluid intake slows passage of food through the intesting and results in hardened stool
how does physical activity affect bowel elimination? promotes peristalsis
what psycological factors affect bowel elimination? emotional stress makes digestion accelerate and peristalsis increase; ulcerative colitis ibs, and certain gastric and duodenal ulcers and chron's disease are associated with stress
how does pain affect bowel elimination? client suppress urge to deficate to avoid pain and thus develops constipation
how does surgery and anesthesia affect bowel elimination? general anesthesia agents used during surgery cause temporary cessation of peristalsis and any surgery that involves direct manipulation of bowel can stop peristalsis
what is a paralytic ileus? temporary stop of peristalsis usually about 24 to 48 hours
how does diagnostic tests affect bowel elimination? exams involveing visualization of GI often requires a perscribed bowel prepartion to ensure bowel is empty
what is constipation? symptom not disease; the signs are infrequent bowel movements, difficulty passing stool, excessive straining, inability to deficate at will, and hard feces
what is a fecal impaction? results from unrelieved constipation is a collection of hardened feces wedged in the rectum that a person cannot expel
what do you do if there is an impaction? digitally remove the impaction
what is diarrhea? an increase in the number of stools and the passage of liquid, unformed feces
what increases diarrhea? antibiotics, food allergies, surgeries or diagnostic testing of lower gi tract, clostridium difficile
what is fecal incontinence? the inability to control passage of feces and gas from anus
what is a hemorrhoid? dilated, engorged veins in the lining of the rectum that are either enternal or external; if the underlying vein is hardened there is a purplish discoloration(thrombosis)
what is a mechanical obstruction? the bowel is physically obstructed by disorders outside the intestine(adhesion or hernia) or by blockages in the lumen of the intestine(tumors,inflammation,strictures,or impactions)
what is a nonmechanical obstruction? know as a paralytic or adynamic ileus; peristalsis is decreased or absent resulting in slowing of the movement or backup of contents
what is common in mechanical and nonmechanical obstruction? contents accumulate at and above the area of obstruction
what is metabolic alkalosis? an obstruction high in the small intestine causes a loss of gatric hydrochloride
what happens when the obstruction is below the duodenum and above large bowel? loss of both acids and bases so that acid-base imbalance is usually not compromised
what is metabolic acidosis? obstruction at the end of the small intestine and lower in the intestinal tract causes loss of alkaline fluids
what is a strangulated obstruction? obstruction with compromised blood flow; the risk for peritonitis is greatly increased. bacteria without blood supply can from an endotoxin and release into the peritoneal or systemic circulation results in septic shock
what happens when there is a strangulated obstruction? bacterial peritonitis can result, the bacteria will lie stagnant in the obstructed intestine, this can cause a problem if blood flow to intestine is compromised
what is the etiology of mechanical obstruction? adhesions, tumors, hernias, fecal impaction, strictures from chron's disease or radiation, intussusception(telescoping a segment of intestine within itself), volvulus(twisting of intestine), fibrosis from endometriosis, and vascular disorders
what is the etiology of nonmechanical obstruction? paralytic ileus, caused by an imbalance associated with decreased peristalsis from trauma, effect of toxin on autonomic intestinal control, can be caused by handling intestine in surgery
