NSG 122 Exam 2 Questions with Verified
Correct Answers
components of the infection cycle** drag and drop test hint**
- infectious agent (virus, bacteria, fungus)
- reservoir (habitat of organism, ex: nose)
- portal of exit (how organism escapes, ex: resp tract)
- means of transmission (ex: direct contact, airborne)
- portal of entry (point where organism enters new host)
- susceptible host (person with weakened immune system)
common portals of exit
- respiratory tract
- GI tract
- GU tract
- breaks in skin
- blood and tissue
stages of infection** drag and drop test hint**
- pre-exposure stage
- incubation period (no signs/symptoms)
- prodromal stage (early non-specific signs/symptoms, most infectious stage)
- full stage of illness (specific signs/symptoms of disease)
- convalescent period (recovery)
factors affecting host susceptibility
,- age
- intact/broken skin
- gender
- stress
- race
- genetics
- general health status
- immune status
- chronic diseases
5 moments for hand hygiene (WHO)** test hint**
1. Before touching a patient
2. Before a clean or aseptic procedure
3. After body fluid exposure risk
4. After touching a patient
5. After touching patient surroundings
When to use soap and water for hand hygiene
- visibly soiled hands
- contact with C. Diff
- before eating
- after using the bathroom
- before assisting with surgical procedure
when to use alcohol based hand sanitizer
- before/after patient contact
- after contact with body fluids if hands not visibly soiled
, - after removing gloves
- after contact with items in patient's environment
- before donning sterile gloves
when to use gloves
- changing bed linens
- contact with C. Diff patients
Procedures requiring sterile technique
- insertion and care of indwelling urinary catheter
- surgical intervention & invasive procedures
- sterile dressing change
- preparing and injecting medicine
risk factors for vancomycin-resistant enterococci (VRE)
- compromised immune system
- recent surgery
- invasive devices
- prolonged antibiotic use
- prolonged hospitalization
types of isolation** test hint**
- contact (gown and gloves, ex: VRE, MRSA)
- droplet (surgical mask, ex: bacterial pneumonia)
- airborne (N95 mask, negative pressure airflow, ex: Covid, TB)
sterile field rules
