Transcript of Concept of Illness
Is a personal state in which the person feels unhealthy
Physical, emotional, intellectual, social, developmental or spiritual functioning is diminished or impaired compared with previous experience
Illness is not synonymous with disease
Disease is an alteration in body functions resulting in reduction of capacities or a shortening of the normal life span
Heredity
Behavioral factors
Environmental factors
1. Symptom Experience
Transition stage
The person believes something is wrong
Experiences some symptoms (physical, cognitive, emotional)
2. Assumption of Sick Role
Acceptance of the illness
Seeks advice, support for decision to give up some activities
3. Medical Care Contact
Seeks advice of health professionals for the following reasons:
Validation of real illness
Explanation of symptoms
Reassurance or prediction of outcome
4. Dependent Patient Role
Becomes dependent to health professionals
Accepts/rejects health professional’s suggestions
Becomes more passive and accepting
May regress to an earlier behavioral stage
One is not held responsible for his condition
One is excused from social roles
One is obliged to get well as soon as possible
One is obliged to seek for competent help
Is any situation, habit, social orenvironmental condition, physiologicalpsychological condition, developmental orintellectual condition, or spiritual or othervariable that increases the vulnerability of anindividual or group to an illness or accident
The presence of risk factors does not meanthat a disease will develop
Genetic and physiological factors
Age
Environment
Lifestyle
The goal of risk factor identification is tomerely assist clients in visualizing thoseareas in their life that can be modified oreven eliminated to promote wellness andprevent illness
Purposes of Inflammation are:
To localize tissue injury
To protect tissue from injury
To prepare tissue for repair
INFLAMMANTS
TISSUE INJURY
1. VASCULAR RESPONSE Transitory vasoconstriction followed immediately by
vasodilation (histamine, bradykinin, prostaglandin E
1. Physical2. Mechanical3. Chemical4. Microbial5. Electrical
INCREASED CAPILLARY PERMEABILITY
HYPEREMIA:Redness (rubor)Heat (calor)
FLUID/ CELLULAR EXUDATION
EXUDATESEdema (tumor)
Pain (dolor)Compression of nerve endings byedema fluidsInjury to nerve endingsRelease of bradykinin
Impaired function
Promote rest to enhance recovery
Reduce swelling
Position: elevate the affected body part to promote venous return
Heat and cold application: cold for first 72 hours; heat after 72 hours
Relieve pain
Increase excretion of microorganism by adequate hydration
Provide adequate nutrition: high caloric, high protein with vitamin A and C rich foods
Administer medication as ordered:
Analgesic/antipyretic: aspirin, acetaminophen, paracetamol, mefenamic acid
Anti-inflammatory: NSAIDs
N – no alcohol
S – Side effect is “BIRTH”
A – aspirin sensitivity – do not give
I – inhibits prostaglandins
D – do take with food
S – stop 5 to 7 days before surgery
Surgery
Incision and drainage: to remove inflammatory exudates to promote healing process
Debridement: to remove necrotic tissue
Surgical and mechanical debridement
Mechanical debridement is performed using the wet-to-dry dressing method
The reparative process begins atapproximately the same time as the injuryand is interwoven with inflammation
Healing proceeds after the inflammatorydebris has been removed
May occur by regeneration or replacement
REGENERATION
Labile cells multiply constantly to replace worn out cells (epithilial cells of the skin and the GI tract)
Permanent cells (neurons) may have permanent destruction, but axons may regenerate
Stable cells have a latent ability to regenerate, if they are damaged or destroyed, they are able to regenerate (kidney, liver, pancreas)
REPLACEMENT
Primary intention healing – wound is clean and dry and the edges are approximated, as in a surgical wound, with little scar and heals in a week
Secondary intention healing – the wound or defect is larger and gaping and has necrotic or dead material, the repair time is longer, the scarring is greater, with loss of specialized function
Hypertrophy
o Increase in cell size leading to increase in organ size
o The stimulus is increased workload
o Leg muscles of runners
o Arm muscles in tennis players
o Cardiac muscles in person with hypertension
Atrophy
o shrinkage in size of cell, leading to decrease in organ size
o Stimuli are decrease in use, blood supply, nutrition, hormonal, stimulation, innervations
o Extremity immobilized in cast, secondary sex organs in aging person
Hyperplasia
o Increase in number of new cells
o Stimulus is hormonal influence
o Breast changes of a girl in puberty or pregnant woman, regeneration of liver cells, new RBCs in blood loss
Dysplasia
o Change in the appearance of cells after they have been subjected to chronic irritation
o Stimulus is reproduction of cells with resulting alteration of their size and shape
o Alterations in epithelial cells of the skin
Metaplasia
o Transformation of highly specialized cell to less specialized cell
o Serves as a protective function because less specialized cells are more resistant to stress
o Ciliated columnar epithelium lining the bronchi of smokers is replaced by squamous epithelium
