Exam 1: Infection Control/Culture/SDOH Flashcards
What is a Healthcare associated infection (HAI’s)?
nosocomial infection, not reimbursable
What are types of HAI’s?
CAUTI (catheter associated UTI)
CLABSI (central line blood stream infection)
SSI (Surgical Site Infection)
VAE (Ventilator Associated Events)
MRSA, VRE, C-diff
Describe the Chain of Infection
Infectious Agent
Reservoir -> think hands for worker
Portal of Exit -> mode of coming out to infect other
Mode of Transmission
Portal of Entry (broken skin, invasive device)
Susceptible host -> immunocompromised (ADD PIC FROM SLIDE)
What makes a host susceptible to infection?
Breaks in skin (pressure ulcers, wounds)
Invasive devices (Foley)
Statis of body fluids (CHF)
Poor nutrition
Stress/Hyperglycemia
Chronic Conditions (DM, HTN, Cancer)
Drug Therapy (Steroids, chemo)
What is the #1 way we prevent the spread of infection?
hand hygiene
What is the difference between a local and systemic infection?
Local – Wound on body part or area - (abscess if left axilla)
Systemic – multiple body systems (Sepsis)
What is the difference between a chronic and acute infection?
Acute – short term ( < 3 months) *UTI, viral pharyngitis, cellulitis
Chronic – long term ( > 3 months) *Hepatitis C, H. Pylori
What is the purpose of antibiotic stewardship?
Creates drug resistant bacteria – hard to treat
What are the signs and symptoms of an infection?
Fever
Chills/Shivers/Rigors
Increased pulse, RR
Inflammatory symptoms
Pain
Purulent DrainageEnlarged lymph nodes
GI symptoms
Increased WBC
Erythrocyte sedimentary rate (ESR)
Lactate level (0.3 -2.6)
+ UA with culture and sensitivity
+ Diagnostic imagine (CXR, CT, MRI)
What is the treatment for an infection?
Rest
Comfort Measures
Ambulation & Positioning
Respiratory Interventions
Nutrition and Hydration
Immunizations
Antimicrobial Therapy
Describe standard precautions.
the minimum infection prevention practices that apply to all patient care, regardless of suspected or confirmed infection status of the patient, in any setting where health care is delivered
What are transmission based precautions?
the second tier of basic infection control and are to be used in addition to Standard Precautions for patients who may be infected or colonized with certain infectious agents for which additional precautions are needed to prevent infection transmission
Describe contact precautions
Requires Gown and Gloves
Direct transmission – care and handling of body fluids (foleys, drains)
Indirect transmission – transfer of infection through contaminated objects (hands, pens, stethoscopes, etc.)
Prevents the healthcare worker from being infected
Prevents spread to other patients, family, staff
C. diff, MRSA
Describe droplet precautions
-Must wear surgical mask w/in 3 feet
-Disease transported by large droplets
-Example: Influenza A
Describe airborne precautions
Private, negative airflow room
N95 Mask
Disease is transported by small droplets over long distances
Example: TB
What is the procedure for donning and doffing PPE?
Don:
1. Hand hygiene
2. Gown
3. Mask
4. Eye protection
5. Hand hygiene and gloves
Doff:
1. Gown and gloves
Exit the room
2. Hand hygiene
3. Remove Face shield and mask
4. Hand hygiene
gloves
face shield
gown
mask
