NURS 334- Inflammation Review
Questions and Correct Answers
Inflammation ✅An immunologic defense against tissue injury, infection, or allergy.
Inflammation = protection
Inflammation always occurs with infection, but inflammation can also occur in the
absence of infection.
Latin word "Inflammare" - to set on fire
Function of inflammatory response function ✅Restitution of normal, functioning cells
after injury.
Fibrous repair when restitution of functioning cells is impossible. The fibrous tissue may
not function the same.
Types of injuries leading to inflammation ✅Mechanical Injury: cut, stab
Thermal Injury: heat, cold
Electrical Injury: electricity
Chemical Injury: corrosive substance. Acid/base
Radiation Injury: exposure to ionizing radiation (chemo)
Biological Assault: food safety, contaminants
Steps in acute inflammatory response ✅Tissue injury and the release of chemical
mediators
Vasodilation and increased blood flow
Swelling and retraction of activated endothelial cells
Increased vascular permeability and leakage of fluid out of the vessel
Movement of immune response cells (leukocytes) (clotting factors)to the site of injury
(thrombosis)
Exudate formation
Movement of glucose and oxygen to the site needing repair
Consequences of an excessive of ineffective inflammatory response ✅Local tissue
damage from compression
Development of chronic inflammation
Systemic pathology:
Atherosclerosis
Chronic renal disease
Neurologic disorders
Autoimmune disease
Risk factors ✅Very old - immune system becomes less able to respond to foreign
pathogens, result in a stronger inflammatory response
, Very young- immature immune system may be unable to control a minor pathogen and
infection may become severe
Uninsured/underinsured- increased risk as may not have access to sufficient or early
care and may result in more severe injury or chronic inflammation
Systemic manifestations ✅Neutrophilia/Leukocytosis
Fever
Malaise
Loss of appetite
Fatigue
Increased plasma proteins
Laboratory tests ✅CBC
WBC with differential
CRP- c reactive protein, inflammation
ESR
Serologic tests to detect specific antibodies or viruses
Radiographic studies ✅MRI
CAT
PET scans
Colonoscopy: bowel inflammation
Primary prevention ✅Reducing risk for injury and infection
Maintain good hygiene
Properly using safety equipment
Properly storing and preparing food
Secondary prevention ✅no specific screening are performed for the general population
for inflammation.
RICE ✅Rest, ice, compression, elevation (RICE)
Most helpful after sprain, strain, or trauma
Helps minimize swelling
Most beneficial for the first 24 to 48 hours after injury
