Q

Stage 3 of decubitus ulcers?

A

Full-thickness skin loss, fat is visible. Bone, tendon, muscles are not exposed. Slough may be present but does not obscure the depth of tissue loss. May include undermining and tunneling.

Q

What to assess for when it comes to pressure ulcers?

A

Location, extent of tissue involvement, presence of undermining or tunneling, wound size in cm.

Width (side to side)
Depth (deepest part of the visible wound bed)

Q

Unstageable/unclassified pressure ulcers?

A

Full thickness tissue loss in which the base of the ulcer is covered by slough (yellow, tan, gray, green, or brown) and/or eschar (tan, brown, or black) in the wound bed.
Until enough slough or eschar is removed to expose the base of the wound, the true depth and therefore stage cannot be determined.

Q

What should be done with stable (dry, adherent, intact without erythema or fluctuance) eschar such as on the heels?

A

It should not be removed because it’s the body’s natural cover

Q

One-way staging as recommended by the WOCN Society?

A

Down-staging/reverse staging of ulcers is not appropriate.
Use the deepest stage and prefix this with the term “healing” or “healed”
If it reopens in the same anatomical site, it retains its original stage.

Q

What are the 3 components of partial-thickness wound repair?

A

Inflammatory response
Epithelial proliferation and migration
Proliferation and migration

18
Q

What are the 4 phases of full-thickness wound repair?

A

Hemostasis (fibrin)
Inflammatory response
Proliferative phase (epithelialization)
Maturation

19
Q

What are the types of dressings for pressure ulcers?

A

Transparent
Hydrocolloid
Negative-pressure wound therapy

20
Q

What are pathological influences on immobility?

A

Postural abnormalities, impaired muscle development, damage to the CNS, and musculoskeletal trauma

21
Q

What are therapeutic reasons for bed rest?

A

Decrease oxygen consumption, weakness, safety, rest a body part (like a fracture), reduce pain, severity of condition

22
Q

What are the levels of activity?

A

Complete bed rest, bed rest with bathroom privileges, bedrest with bedside commode, dangle on the side of bed, up to bedside chair, Out of bed with assistance, OOB ad lib

23
Q

What systemic effects does immobility have on the metabolic and cardiovascular systems?

A

Metabolic is endocrine, calcium absorption, and GI function, glucose intolerance, negative nitrogen balance
Cardiovascular is orthostatic hypotension, thrombus, postural hypertension, cardiac muscle atrophy

24
Q

What systemic effects does immobility have on urinary elimination and respiratory system?

A

Urinary elimination is urinary stasis and renal calculi

Respiratory is atelectasis, hypostatic pneumonia, nephritis

25
Q

What systemic effects does immobility have on the skeleton and integumentary system?

A

Skeleton is impaired calcium absorption, joint abnormalities
Integumentary is pressure ulcers and ischemia.

26
Q

What are examples of nursing diagnoses for the respiratory system related to immobility?

A

Ineffective airway clearance
Ineffective breathing pattern
Impaired gas exchange

27
Q

What are examples of nursing interventions for the respiratory system related to immobility?

A

Assess lung sounds, for decreased ability to cough, accumulated secretions, colored sputum, fever, shortness of breath changes in skin color, pulse ox.
TCDB every two hours
Suction oropharyngeal airway prn
Chest physiotherapy, provide hydration

28
Q

What are examples of nursing diagnoses for the cardiovascular system related to impaired mobility?

A

Risk for orthostatic hypotension
RF impaired tissue perfusion
RF decreased cardiac output

29
Q

What are nursing interventions for the cardio system related to impaired mobility?

A

Use anti embolism stockings
Raised and lower HOB several times. Raise HOB to fowler’s before getting out of bed.
Dangling and assisting client to stand
Observe for symptoms

30
Q

A blood clot that adheres to the wall of a blood vessel or organ
A clot or part of a clot that has broken off from the place where it was formed and has traveled to another organ

A

Thrombus
Thromboembolism

Blocks blood flow to the area beyond where it lodges, can be lethal if it travels to the heart, lungs, or brain

31
Q

An abnormal and possibly permanent condition characterized by fixation of the joint.

A

Joint contracture

32
Q

What are nursing interventions for the musculoskeletal system related to impaired mobility?

A

Passive and active range of motion/ROM
Continuous passive motion machine/CPM
Mobility aids such as canes, walkers, crutches

33
Q

How to do passive range of motion exercises/PROM?

A

Slow and smooth movements to the point of resistance, not past capacity. Repeat each movement five times. Stand on the side closest to the joint being exercised. Support distal and proximal joint.

34
Q

What are nursing interventions for the urinary system related to impaired mobility?

A

Assess intake and output. Turn frequently, OOB ASAP. Hydrate the patient. Proper positioning on the bedpan.

35
Q

What are nursing interventions for the GI system related to impaired mobility?

A

Hydration 1100 mL - 1400 mL a day minimum. Getting them out of bed, ROM. High fiber diet laxatives if needed (stool softeners don’t increase peristalsis). Frequent position changes.

36
Q

What are the psychosocial effects of immobility?

A

Emotional and behavioral responses. Hostility, giddiness, fear, anxiety, mood changes. Sensory alterations (disorientation). Altered sleep patterns. Changes in coping. Depression, sadness, rejection, isolation.

37
Q

What are nursing interventions for the psychosocial aspects related to immobility?

A

Activities, reading, reducing noise when working night shift to help the patients get better sleep.
Cluster activity to get things done at once, to give them periods of uninterrupted sleep.
Keep a routine.

38
Q

Develops when pressure on the skin is greater than pressure inside the small peripheral blood vessels supplying blood to the skin.

A

Tissue ischemia

39
Q

What are nursing interventions for the integumentary system related to immobility?

A

Repositioning minimum every two hours. Sit in chair only one hour uninterrupted. Moisturize skin but not too moist, use a barrier cream. Adequate hydration and diet. Relieve pressure.

40
Q

Patients need how much of fluids per day to help prevent renal calculi and urinary tract infection?

A

2000 and 3000 mL
