Skin Integrity Objectives Flashcards by Hannah Mcnece

A patient has a pressure injury on the coccyx measuring 5 cm by 3 cm that is covered with eschar. How should the nurse classify this wound?

A. Stage 2 pressure injury
B. Stage 3 pressure injury
C. Stage 4 pressure injury
D. Unstageable pressure injury

Answer: D.) Unstageable pressure injury
Rationale: Eschar is a black, leathery covering made up of necrotic tissue. An ulcer covered in eschar cannot be classified using a staging method because it is impossible to determine the depth

A patient is recovering from a ruptured appendix. Because the surgeon did not surgically close the wound, the nurse knows the wound will heal by:

A. Primary intention
B. Secondary intention
C.Tertiary intention
D. Approximation

Answer: A.) Secondary Intention
Rationale: Secondary intention healing occurs when a wound is left open, and it heals from the inner layer to the surface by filling in with beefy, red granulation tissue.

Age factor that affects skin integrity for the older adults include what

Sebaceous and sweat gland activity decreases resulting in drier skin

Xerosis

Lose lean body mass and the subcutaneous tissue layer thins

the dermal layer loses elasticity due to changes in collagen fibers

these changes make the skin prone to breakdown and prolong wound healing - which is why an older persons skin takes twice as long as a younger adult

Pressure ulcers are directly caused by which condition at the site? A. Compromised blood flow B. Edema C. Shearing forces D. Inadequate venous return

Answer: A. Compromised blood flow Rationale: Pressure ulcers are caused by unrelieved pressure that compromises blood flow to an area, resulting in ischemia (inadequate blood supply) in the underlying tissue.

Scars are only _____% as strong as original tissue

Stage 2 pressure ulcers do not involve

sloughing or bruising

What are some nursing interventions you can do to minimize pressure injuries

monitoring sites of bony promises (turn client ) Managing moisture (changing when they are wet applying moisture barriers) Dressings (to keep site dry and away from infection or worsening) Minimize pressures (by turning client regularly )

What are the advantages/risks of dry heat treatment and how is it applied?

may be applied with electric heating pads, disposable hot packs, or hot water bags. Electric heating pads have the advantage of providing a constant temperature, but the risk of burns is high. Aquathermia pads may also be used for dry heat application. Disposable hot packs and hot water bags or bottles are also available

what are the six categories of the braden scale

``` sensory perception moisture activity mobility nutrition friction shear ```

What are the two distinct layers of the skin

Epidermis and the Dermis

What does cold treatment (cooling baths, cold compresses, or dry cooling) do to the body

The application of moist or dry cold causes vasoconstriction and decreases capillary permeability. It produces local anesthesia, reduces cell metabolism, increases blood viscosity, and decreases muscle tension. It also slows bacterial growth

What does the dermis layer of the skin consists of ?

thinner second layer contains blood and lymphatic vessels, nerves, bases of hair follicles, and subcutaneous and sweat glands provides strength and elasticity to the skin and is generously supplied with blood vessels

What does the epidermis layer consist of?

It is the thick outer layer Consists of stratified squamous epithelial tissue composed of keratinized (dead) cells and contains melanin

What does the integumentary system consist of?

Skin Subcutaneous layer Hair Nails Sweat glands Sebaceous glands

what does the maturation phase consist of and how long does it last?

final phase of healing occurs after proliferation or granulation phase. continues after the wound has closed, the initial collagen fibers are broken down and remodeled into an organized structure (scar tissue)

What does the subcutaneous layer consist of

connective and adipose tissue

What factor affecting skin integrity is being described below: excessive exposure leads to maceration increasing the likelihood of skin breakdown Inconvenience and fever are the most common sources

Moisture

what happens in a brisk hemorrhage?

blood often pools underneath the client as the dressing becomes saturated

what happens in the Proliferation or granulation phase and how long does it last?

these phase occurs from days 5 to 21 Cells develop to fill the wound and resurface the skin. Fibroblasts go to the wound and form collagen adding strength to the healing wound. new blood and lymph vessels form around the edge of the wound forming granulation tissue and seal the wound over

what is a closed wound

exists when there are no breaks in the skin. Contusions (bruises) or tissue swelling from fractures are common closed wounds

what is a full - thickness wound

extends into the subcutaneous tissue and beyond | penetrating is also sometimes added to indicate that the wound involves an organ

what is a hemmorrhage?

profuse or rapid loss of blood. Hemostasis (or cessation of bleeding) usually occurs within minutes of the injury.

what is a internal hemmorrhage?

could be collection of blood under the skin and forms a hematoma because the blood cannot escape, large enough and it can cause pressure on surrounding tissue or impede blood flow. which causes swelling of the affected area, pain and changes in vital signs

what is a open wound

occurs when there is a break in the skin or mucus membranes

what is a partial- thickness wound

extends through the epidermis but not through the dermis

what is a superficial wound ?

involves only the epidermal layer of skin. The injury is usually the result of friction, shearing, or burning

What is caused by unrelieved pressure that compromises blood flow to an area resulting in ischemia in tissue

pressure ulcers

What is colonization

bacteria begin to increase in number but cause no harm.

What is contamination of a wound

refers to the presence of microorganisms in the wound | all chronic wounds are considered contaminated

What is critical colonization

bacteria begin to overwhelm the bodys defense. May be detected in subtle signs, such as increase in drainage

what is directly caused by compromised blood flow

pressure ulcers

what is Hemostasis in the inflammatory phase ?

at the time of injury, tissue and capillaries are destroyed, causing blood and plasma to leak into the wound. Area vessels constrict to limit blood loss, platelets for a clot

What is infection

Microorganisms are causing harm by releasing toxins, invading body tissues, and increasing the metabolic demand of the tissue. Infection of the skin makes it more vulnerable to breakdown and impedes healing of open wounds . If not stopped bacteria can enter the systemic circulation

What is inflammation in the inflammatory phase?

characterized by edema, erythema, pain, temperature elevation, and migration of white blood cells into the wound tissues. macrophages engulf bacteria and clear debris. plasma proteins and fibrin form a scab on the wound surface to seal it

What is melanin? and its function?

a pigment that gives the skin color | Functions: protects against UV rays, together with circulating blood

what is the function of the subcutaneous layer of skin?

provides insulation, protection, and calories in case of starvation

What is the length of healing time for a acute wound ?

expected to be short duration. In a healthy person these wounds heal very quickly with no complications

what is the length of healing time for a chronic wound?

exceed the expected length of recovery because healing has been interrupted or stalled due to infection, continued trauma ischemia, or edema. Unless the wound is properly diagnosed and the underlying disease process is treated these wounds can linger for months to years

What is the primary goal of the nurse caring for a patient with an open wound? A. The client will finish their antibiotics. B. The wound will remain free of infection. C. The client will increase caloric intake. D. The wound will heal without scarring

Answer: B.)The wound will remain free of infection Rationale: Wounds healing by secondary intention are more prone to infection, therefore the primary goal is to prevent infection.

What is the purpose of moist heat treatment and how is it applied?

Adding moisture to heat amplifies the intensity of the treatment. Moist heat can be applied in several forms, depending on the skin condition: a washcloth or towel compress, a gauze compress, or soaks and baths.

what nutrient is being described below: low levels predispose patients to skin breakdown and inhibits wound healing aide in providing fuel for wound healing and maintaining a waterproof barrier

Cholesterol

What nutrient is being described below: | Vital to the formation and maintenance of collagen

Vitamin C Zinc Copper

What nutrient is being described below: when inadequate, the body uses proteins for energy (catabolism); they are then unavailable for building and maintenance functions (anabolism) When prolonged, the person experiences weight loss, loss of subcutaneous tissue, and muscle atrophy. As a result, padding between the skin and the bones decreases, predisposing the skin to pressure injury.

Caloric intake

What nutrient is being described below: maintains the skin repairs minor defects preserves intravascular volume As levels decrease minor defects cannot be repaired, fluid leaks from the compartment of dependent areas and edema develops

Protein

What nutrient is being described below: | when deficient skin os prone to injury especially when exposed to pressure, shearing, friction, and moisture

Hydration

What nutrients are essential to the integrity of the skin

``` protein cholesterol calories fluid vitamin C minerals ```

What type drain is described a flexible, flat latex tube that is placed in the wound bed but usually not sutured into place. A clip or pin may be attached to the drain at the insertion site to keep it from slipping into the wound

penrose

What type of drain is described The provider may order a device to be “placed to suction.” This means you will compress the device to create suction and facilitate removal of drainage

Jackson-Pratt or Hemovac

what type of healing is being described : occurs when a wound involves minimal or no tissue loss, and edges are clean, little scaring is expected (hairline) A surgical incision heals this way

primary (first) intention healing

what type of healing is being described below : involves extensive tissue loss that prevents clean edge closing, or the wound should not be closed because of infection --- which makes the wounds heal from the inner layer to the surface with beefy red granulation these wounds develop more scar tissue

secondary intention healing

What type of healing is being described below: occurs when two surfaces are sutured by brining the two inner sides of granulation tissue together these wounds require strict aseptic technique for wound dressings

Tertiary intention healing

What type of healing is being described? occurs when a wound affects only the epidermis and dermis. No scar forms (means you cannot tell that the skin was ever harmed)

Regenerative/Epithelial Healing

what type of pressure injury is described An area of skin that is intact but persistently discolored. It might be purplish or deep red, painful, or boggy, or have a blister. Pain and temperature change often come before skin color changes.

Deep tissue pressure injury

What type of pressure injury is described below Involves full-thickness skin loss. The base of the wound is obscured by slough or eschar.

Unstageable Pressure Injury

What type of wound complication is being described below Rupture of one or more layers of a wound. Most likely to occur in the inflammatory phase of healing, before large amounts of collagen have been deposited in the wound to strengthen it. The most common causes are poor nutritional status, inadequate closure of the muscles, wound infection, or increased tension on the suture line (coughing, lifting an object). Usually associated with abdominal wounds. Patients often report feeling a “pop” or tear, especially with sudden straining from coughing, vomiting, or changing positions in bed.

Dehiscence

what type of wound complication is being described below: Microorganisms can be introduced to a wound during an injury, during surgery, or after surgery. Suspect if a wound fails to heal. Localized swelling, redness, heat, pain, fever foul-smelling or purulent drainage, or a change in the color of the drainage may also indicate In a contaminated or traumatic wound, the symptoms are likely to occur within 2 to 3 days. In a clean surgical wound, you will usually not see signs and symptoms until the fourth or fifth postoperative day.

Infection

What wound complication is being described : An abnormal passage connecting two body cavities or a cavity and the skin. often result from infection or debris left in the wound. An abscess forms, which breaks down surrounding tissue and creates the abnormal passageway.

Fistula

what wound complication is being described total separation of the layers of a wound with internal viscera protruding through the incision. This rare complication is a surgical emergency. Immediately cover the wound with sterile towels or dressings soaked in sterile saline solution to prevent the organs from drying out and becoming contaminated with environmental bacteria.

Evisceration you would not but a binder on the incision

When is the epidermis completed replaced ?

every 3-4 weeks

where do you normal see an external hemorrhage in a hospital setting

bloody drainage on dressings and in wound draining devices

Why are clients at risk for impaired skin integrity when they have a decreased sensation

they are less able to sense when thier skin is in harm, EX. they get a cut and are unaware they put their hand on a burner and they cannot feel it and end up with burns

why are clients with impaired cognitive ability at risk for skin impairment like alzheimers, deminta, etc.

they are not aware of the need to reposition, can be subtle and difficult to recognize

Why does the subcutaneous layer vary in thickness in different body sites?
