What personal protective equipment (PPE) is essential when entering the room of a suspected COVID-19 patient?
Surgical mask
Gloves
Face shield
Shoe covers
Surgical masks filter respiratory droplets, which are the primary transmission route for COVID-19, and are required for droplet precautions. Gloves and face shields protect other routes but do not replace masks for inhalation protection. Shoe covers are not relevant for droplet-based transmission.
How long should you wash your hands with soap and water to effectively remove pathogens?
5 seconds
40 seconds
1 minute
At least 20 seconds
Washing for at least 20 seconds ensures removal of pathogens from all hand surfaces. Shorter durations are less effective at breaking down oils and microbes. While longer washing can further reduce microbes, 20 seconds is the minimum recommended.
When should single-use gloves be disposed of in patient care?
After every hour of use
After each patient encounter
At the end of the shift
Only when visibly soiled
Single-use gloves must be discarded after each patient encounter to prevent cross-contamination between patients. Reusing gloves beyond one patient increases infection risk. They should also be changed if torn or heavily soiled.
What is the proper way to cover a cough to reduce droplet spread?
Cough into the hands
Cough into a tissue then shake it out
Do not cover the mouth
Cough into the elbow
Coughing into the elbow prevents respiratory droplets from contaminating hands and surfaces. Using hands or shaking a tissue can spread pathogens via touch. Proper respiratory etiquette reduces droplet transmission.
What is the primary transmission route of COVID-19?
Bloodborne
Vector-borne
Respiratory droplets
Foodborne
COVID-19 spreads mainly through respiratory droplets expelled when infected individuals cough, sneeze, or speak. Bloodborne, vector-borne, and foodborne routes are not significant for SARS-CoV-2. Recognizing droplet transmission informs control strategies.
In which order should PPE be donned to maximize protection?
Gown, gloves, mask, goggles, hand hygiene
Hand hygiene, gloves, gown, mask, goggles
Mask, goggles, gown, gloves, hand hygiene
Hand hygiene, gown, mask/respirator, goggles/face shield, gloves
Donning PPE in the order of hand hygiene, gown, mask or respirator, eye protection, and then gloves ensures each piece is applied over clean hands and provides proper sealing. Incorrect sequences can compromise the barrier effect of PPE. This order minimizes contamination risk.
According to WHO's 'Five Moments for Hand Hygiene', which is the first moment?
After touching patient surroundings
Before touching a patient
Before an aseptic task
After body fluid exposure risk
The first moment for hand hygiene is before touching a patient to prevent transferring pathogens from healthcare workers to patients. It is one of the five critical times identified by WHO. Other moments occur later in the care sequence.
Which isolation precautions are recommended for routine care of a patient with suspected COVID-19?
Standard precautions only
Contact and droplet precautions with eye protection
Enteric precautions
Airborne precautions without eye protection
Contact and droplet precautions with eye protection block transmission via respiratory droplets and contaminated surfaces. Standard precautions alone do not address droplet spread, and airborne without eye protection ignores mucous membrane risk. Enteric precautions are for gastrointestinal pathogens.
After performing an aerosol-generating procedure on a COVID-19 patient, which mask should be used?
Cloth mask
Surgical mask
N95 respirator or equivalent
No mask required
Aerosol-generating procedures can create fine particles that remain airborne; N95 respirators filter at least 95% of these particles. Surgical and cloth masks are not sufficient for aerosols, and not wearing a mask poses high risk. Proper respiratory protection is critical.
What does fomite transmission refer to in the context of COVID-19?
Direct person-to-person contact
Transmission through mosquitoes
Airborne spread of droplets
Indirect transfer via contaminated surfaces or objects
Fomite transmission involves acquiring the virus by touching contaminated objects and then touching mucous membranes. It differs from airborne, vector-borne, and direct contact routes. Disinfection of surfaces reduces fomite-mediated spread.
What is the correct technique for removing a soiled disposable gown?
Rip gown off from the front
Untie fasteners and pull away rolling inside-out
Slide off from shoulders without touching outside
Shake to remove debris before removal
Removing a gown by untying fasteners and rolling it inside-out prevents contact with the contaminated exterior surfaces. Ripping or shaking spreads contaminants, and sliding without proper technique can transfer pathogens. Proper removal protects healthcare workers and the environment.
Which of the following is NOT one of WHO's 'Five Moments for Hand Hygiene'?
After using the restroom
After body fluid exposure risk
After touching patient surroundings
Before patient contact
WHO's Five Moments include before touching a patient, before aseptic procedures, after body fluid exposure, after touching a patient, and after touching patient surroundings. Hand hygiene after using the restroom is important but not one of these five clinical moments.
What minimum physical distance is recommended to reduce droplet transmission of COVID-19?
2 feet
6 feet (2 meters)
No distancing required
10 feet
Maintaining at least 6 feet (2 meters) distance reduces the chance that respiratory droplets reach another person. Shorter distances increase exposure risk. Proper distancing complements mask use and other control measures.
Which environmental factor increases the risk of aerosol transmission indoors?
Poor ventilation
Bright lighting
Cold temperature
High humidity
Poorly ventilated spaces allow aerosol particles to accumulate, increasing transmission risk. High humidity, lighting, and temperature have less direct impact on aerosol persistence. Adequate ventilation disperses and dilutes airborne particles.
How should a used disposable surgical mask from a COVID-19 patient room be discarded?
Placed in a recycling bin
In a regular trash bin
Left on the patient bedrail
In a designated biohazard waste container
Used masks potentially carry infectious material and must be discarded as regulated medical waste in biohazard containers. Regular trash or recycling bins are inappropriate and increase contamination risk. Proper disposal limits environmental and exposure hazards.
What is the minimum required air changes per hour (ACH) for an airborne infection isolation room?
12 ACH
2 ACH
6 ACH
20 ACH
Airborne infection isolation rooms should have at least 12 air changes per hour to quickly remove airborne contaminants. Lower ACH values do not adequately dilute or remove pathogens. While higher rates further reduce risk, 12 ACH is the minimum standard.
When transporting a confirmed COVID-19 patient through the facility, which precautions are recommended?
Patient in open bed without mask; staff wear N95 respirator only
Patient wears a surgical mask; staff wear N95 respirator, gown, gloves, and eye protection
No mask on patient; staff wear only a surgical mask
Patient in wheelchair without mask; staff wear gloves only
Having the patient wear a mask reduces droplet emission, while staff wearing full PPE protects against droplets and contact. Incomplete PPE leaves gaps, and lack of patient masking increases source emission. This combined approach minimizes transmission during transport.
Which method is recommended for decontaminating N95 respirators during critical shortages?
UV-A light exposure
Autoclaving at 121°C
Boiling in water
Vaporized hydrogen peroxide
Vaporized hydrogen peroxide effectively decontaminates N95 respirators without degrading filter performance. Boiling, autoclaving, and UV-A can damage mask integrity or lack validation. Proper decontamination extends respirator usability safely.
What is the recommended quarantine period for healthcare workers exposed to COVID-19 without symptoms?
7 days
14 days
No quarantine if asymptomatic
21 days
A 14-day quarantine covers the maximum incubation period for COVID-19, reducing the risk of presymptomatic spread. Shorter periods may miss late-onset cases, and absence of quarantine risks transmission. Monitoring for symptoms throughout is essential.
SARS-CoV-2 can remain viable on plastic surfaces for up to how many hours?
168 hours
12 hours
72 hours
24 hours
Research indicates SARS-CoV-2 remains viable on plastic surfaces for up to 72 hours under laboratory conditions. Viability decreases over time but remains detectable beyond 24 hours. Understanding surface survival informs cleaning frequency and fomite control.
