Unit One Flashcards
Two types of body temperature
Core temperature and surface temperature
Hyperthermia
More heat produced than lost Etiology: -Viral infections -Bacterial infections -Tissue breakdown
Hypothermia
More heat lost than produced Etiology: -Impairment of hypothalamus -heat loss greater than heat production -excessive loss of body heat
Thermoregulation
There are more cold receptors than warm receptors
Pyrexia
Body temp is above typical range
Hyper pyrexia
Very elevated body temp (above 105)
Afebrile
Patient does not have a fever
Hypothermia
Core body temperature is below limit of normal temp
Data
- Wellness behaviors
- illness/ signs and symptoms
- strengths and weaknesses
- risk factors
Two types of data
Subjective and objective
Sources of data
Secondary and Primary
Primary Data
Comes from pt
Secondary Data
Comes from support people, client records, healthcare professionals, literature
Types of assessment
Initial
Problem
Emergent
Ongoing
Initial Assessment
Establishes baseline data; problem identification
Problem focused assessment
Determine status of a previously identified problem
Emergent Assessment
During a crisis
Ongoing Assessment
Occurs sometimes after initial assessment; comparison of initial and current data
Methods of Assessment
Inspection
Palpating
Percussion
Auscultation
Method of Assessment should be done in IPPA order unless
You are assessing the abdomen
Profusion
The process of the cardiovascular system providing a continuous supply of oxygenated blood to every cell in the body
What to look at when do ing a Perfusion assessment
Skin color Temp Abnormal pulsation Edema Capillary refill Blood pressure
Evidence based practice (EBP)
- An integration of best evidence available, nursing expertise, and the values and preferences of the individual.
- Serves to bridge the gap between best available evidence and the most appropriate nursing care.
Barriers to EBP
- Work schedule demands
- Client preferences
- Access to technology
- Limited knowledge
- Lack of support from manager
- Lack of access to continuing education
- Attitude of individual nurses
- Resistance to change
Effects of EBR on nursing
Promotes best practice Credibility of nursing as a profession Accountability of nursing practice Cost effective nursing care Generate knowledge, and use current problems
Developing EBP
Step 1: develop a clinical question
Step 2: Retrieve the evidence
Step 3: Evaluate evidence
Step 4: Apply the evidence
Collaboration
Two or more people working towards a common goal by combining skill, knowledge, and resources
Healthy people initiative
Initiatives to make our population as a whole better
Maslow’s Hierarchy of Needs
Physical, Safety, Love and Belongingness, Self Esteem, Self Actualization
Inflammation
The body’s response to help reduce the effects of what the body views as harmful.
Purposes of inflammation
Protection
Encourages healing
Preventative
What is inflammation?
An adaptive response that brings fluid, dissolved substances, and blood cells into that interstitial tissue.
Non-specific
Neutralizes invader, destroyed tissue is removed, and healing begins
Debridement
Debridement
Preparation for wound healing
5 cardinal signs of inflammation
Heat Redness Swelling Pain Loss of fune
How many stages of inflammation are there?
Three
Stage one of inflammation
Vascular and cellular response:
Can cause edema and pain
Vessels constrict and become permeable and fluid leaks out inter interstitial tissue
It’s swollen
Stage two of inflammation
Exudate production:
Helps to dilute any toxins
May have drainage (puss)
Healing is starting to take place
Stage three
Reparative Phase:
Regeneration of the tissue
Things start to return to normal
I’d regeneration is not possible you may end up with fibrous tissue
Inflammation can be _________.
Acute or Chronic
Chronic Inflammation
Lasts longer periods of time
I.E. Lupus
Acute Inflammation
Up to 10 days before duration before symptoms subside and repair starts
I.e. bee sting
ESR
Erythrocytes Sedimentation Rate:
Tells provider that there is inflammation somewhere n the body
CRP
C-reactive Protein; measures how much infection there is
WBC
White blood cell count: its going to tell you that infection is present that is causing the inflammation by how high the WBC is.
What interventions are there for Inflammation?
Immobilization Antipyretic Antibiotics Healthy diet Instruct patient to take all medications Change dressings as needed Surgery
Pharmacological interventions for inflammation:
Anti-inflammatory drugs
Corticosteroids for severe inflammation
Chain of infection
Infectious agent>Reservoir>Portal of Exit>Means of Transmission>Portal of Entry>Susceptible Host (repeat)
Where can the chain of infection be broken?
At means of Transmission
How can the chain of infection be broken?
Standard precautions, vaccinations, sterilization, instrument management, hand hygiene
Infectious Agents
Bacteria, fungi, viruses, Protozoa
Reservoirs
People, environment
Portal of exit:
Excretions secretions, skin, droplets
Means of Transmission
Direct contact, ingestion, airborne
Portal of Entry:
Mucus membrane, GI Tract, Respiratory, Broken Skin
Susceptible Host:
Unvaccinated people, immunosuppressant, diabetes, Surgery, burns, cardiopulmonary
What increases the risk for infection?
Age Heredity Stressors Nutrition Cancer Treatments Cancer treatments Medications Anti-inflammatory meds Antibiotics Diseases
Diagnostic tests for Infection?
WBC Procalcitonin (CTpr; Asepsis) C&S Serological Testing X-rays Ultrasounds Lumbar puncture
Antibiotic Peak/Trough
Used to test for infection
Verifies medication is in therapeutic range at all times
Peak
Highest level of a drug in your system; drawn shortly after medicine is given
Trough
Drawn shortly before the next does; measures the lowest level of a drug
Infection is caused by:
An organism
I.e. Bacteria, fungus, etc
Inflammation is _________.
Just the body’s response
Infection leads to ________.
Inflammation
Inflammation and Infection can both be __________ and ___________.
Localized and systemic
Localized
In one area of the body
Redness swelling heat
I.e. Bee sting, ant bite, pink eye.
Systemic
Wide spread throughout the body
Most Common Systemic infection in the hospital:
Sepsis
Nosocomial infections
Hospital acquired infections (HAI)
Does not originate from the patients original diagnosis
Nosocomial infections become evident ____________ hours after hospitalization.
48
Nosocomial Infections lead to
Increased hospital stays
Increased healthcare costs
Decreased reimbursement from insurance
