chapter 11: inflammation and wound healing

inflammatory response

is sequential reaction to cell injury
-it neutralized and dilutes the inflammatory agent, removes necrotic materials, and establishes an environment
suitable for healing and repair.

'inflammation is always present w infection, but infection is not always present w inflammation

...

infection

involves invasion of tissues or cells by microorganisms such as bacteria,fungi, and viruses.

infection can also be caused by ________

-heat, radiation, trauma, chemicals, allergens, and autoimmune reaction.

inflammatory response can be divided into______

vascular response,cellular response, formation of exudate, and healing

vascular response

...

cellular response

-neutrophils and monocytes move from circulation to the site of injury.

chemotaxis

is directional is the migration of WBCs to the site of injury, resulting in an accumulation of neutrophils and monocytes at the site.

neutrophils

are the first leukocytes to arrive at the injury site (usually within 6-12 hrs.
- they phagocytize (engulf) bacteria, other foreign material and damaged cells.
-short life span of (24-48hrs) dead neutrophils accumulate.

Pus

-mixture of dead neutrophils, digested bacteria, and other cell debris accumulates as a creamy substance.

Elevated WBC

#NAME?

bands

-immature neutrophils released by the bone marrow into the circulation. (because of the demand)

segmented neutrophils

mature neutrophils

shift to left

the finding of increased number of band neutrophils in circulation.
-commonly found in pts w acute bacterial infections

monocytes

-second type of phagocytic cells that migrate from circulating blood.
-they usually arrive at the site within 3-7 days after the onset of inflammation.
-monocytes transform into macrophages when entering tissue spaces.

macrophages

assist in phagocytosis of the inflammatory debris.
-cleaning of the area before healing can begin.
-have long life span. they can multiply and may stay in the damaged tissues for weeks.

histamine

-stored in granules of basophils, mast cells, platelets
-causes vasodilation and increased capillary permeability

local manifestations of inflammation

Redness-hyperemia from vasodilation
heat- (calor) increased metabolism at the inflammatory site
pain- (dolor) changed in pH. nerve stimulation by chemicals
(e.g histamine,prostaglandings) pressure from fluid exudate
swelling-(tumor) fluid shift to interst

systemic manifestations of inflammation

-increased WBC count w shift to left,malaise, nausea, and anorexia, increased pulse and resp rate and fever.

acute inflammation

the healing that occurs in 2 to 3 weeks and usually leaves no residual drainage .
-neutrophils are predominant cell type at the site

subacute inflammation

has the features of the acute process but lasts longer.
-ex: infective endocarditis is a smoldering infection w acute features but lasts longer up to weeks or months

chronic inflammation

lasts for weeks, months or even years. the injurious agent persists or repeatedly injures tissue.
-predominant cell types are macrophages or lymphocytes.
ex; rheumatoid arthritis and osteomyelitis.
- the prolongation of inflammation may be the result of a

adequate nutrition

-is essential so that the body has necessary factors to promote healing when injury occurs.
-high fluid intake is needed to replace fluid loss from perspiration.

vital signs (acute care) inflammation

-taking corticosteroids or receiving chemotherapy the manifestations of inflammation may be masked.
-early symptoms of inflammation may be malaise or "just not feeling well"
-with infection the temperature may rise, and pulse and resp rate may increase.

vitals signs (fever) moderate fevers

-(up to 103F) usually produce few problems in most pts.
if pts is very young or very old it is extremely uncomfortable
-the use of antipyretics should be considered.
-FEVER w immunosuppressed patient should be treated immediately w antibiotic therapy beca

A nurse is teaching a patient how to promote healing following abdominal surgery. What should be included in the teaching (select all that apply.)?
A. Take the antibiotic until the wound feels better.
B. Take the analgesic every day to promote adequate re

answer: C and D
rationale=Fluid is needed to replace fluid from insensible loss and from exudates as well as the increased metabolic rate. Protein corrects the negative nitrogen balance that results from the increased metabolic rate and that needed for sy

A patient arrives in the emergency department reporting fever for 24 hours and lower right quadrant abdominal pain. After laboratory studies are performed, what does the nurse determine indicates the patient has a bacterial infection?
A. Increased platele

answer: C
rationale=The finding of an increased number of band neutrophils in circulation is called a shift to the left, which is commonly found in patients with acute bacterial infections. Platelets increase with tissue damage through the inflammatory pr

A patient had abdominal surgery last week and returns to the clinic for follow-up. The nurse assesses thick, white, malodorous drainage. How should the nurse document this drainage?
A. Serous
B. Purulent
C. Fibrinous
D. Catarrhal

answer: B
rationale= Purulent drainage consists of white blood cells, microorganisms, and other debris that signal an infection. Serous drainage is a thin, watery, clear or yellowish drainage frequently seen with broken blisters. Fibrinous drainage occurs

A patient has been provided with a compression dressing in an attempt to facilitate rapid healing of an ankle sprain. What is a priority nursing assessment?
A. Frequent examination of the character and quantity of exudate
B. Monitoring for signs and sympt

A patient is ordered to receive acetaminophen 650 mg per rectum every 6 hours as needed for fever greater than 102�F. Which parameter would the nurse monitor, other than temperature, if the patient requires this medication?
A. Pain level
B. Intake and out

answer: B
rationale=
Because fever can lead to excessive perspiration and evaporation of body fluid via the skin, the nurse should monitor the patient's overall intake and output to be sure that the patient remains in proper fluid balance. Pain, oxygen sa

A patient is postoperative after a breast reduction and arrives for a follow-up appointment at the clinic. The nurse assesses excess soft pink tissue from the surgical incision site. What complication of wound healing does the nurse recognize this to be?

Answer: D
rationale=Excess granulation tissue, the excess soft pink tissue on the wound, is what this complication of wound healing is called. Adhesions are bands of scar tissue that form between or around organs. Wound contraction, which is a normal part

A patient with pneumonia has a fever of 103�F. What nursing actions will assist in managing the patient's febrile state?
A. Administer aspirin on a scheduled basis around the clock.
B. Provide acetaminophen every 4 hours to maintain consistent blood level

answer:B
rationale= Antipyretics should be given around the clock to prevent acute swings in temperature. ASA would not be the drug of choice because of its antiplatelet action and accompanying risk of bleeding. When treating fever, drug interventions are

After performing an otoscopic examination on a client who reports a decrease in hearing acuity, the primary healthcare provider diagnoses the condition as otitis media. Which assessment finding supports the diagnosis?

answer:redness of the eardrum
Many conditions are associated with a decrease in hearing acuity. One such condition is otitis media. This condition is diagnosed by redness of the eardrum observed during the otoscopic examination.

what are steroids used for?

answer: are used for their antiinflammatory, vasoconstrictive, and antipruritic effects.
-Steroids increase the incidence of infections because they are antiinflammatory agents and mask symptoms of infection.
-Steroids increase fluid retention because the

A client has a history of gastroesophageal reflux disease (GERD). Why should the nurse also monitor the client for clinical manifestations of heart disease?

answer: Esophageal pain may imitate the symptoms of a heart attack.
rationale=Symptoms associated with myocardial infarction may be interpreted by a client as esophageal reflux and therefore ignored.
- Laboratory workups help differentiate these two diagn

Allergic contact dermatitis

is a manifestation of delayed hypersensitivity in which absorbed agents act as antigens.
Sensitization occurs after one or more exposures, and lesions may appear 2 to 7 days after contact with allergens.
