What is the primary transmission route for Methicillin-resistant Staphylococcus aureus (MRSA) in healthcare settings?
Direct contact transmission
Vector-borne transmission
Foodborne transmission
Airborne transmission
MRSA is primarily spread through direct contact with contaminated hands or surfaces. Airborne, vector-borne, and foodborne routes are not typical for MRSA in healthcare environments.
Which of the following is a standard precaution recommended for all patient care interactions to minimize infection risks?
Administering prophylactic antibiotics
Performing hand hygiene
Using dedicated rooms for each patient
Wearing an N95 respirator for all patients
Hand hygiene is the cornerstone of standard precautions and must be performed before and after all patient contacts. The other options are not required for every patient interaction.
Which level of disinfection is appropriate for cleaning non-critical environmental surfaces such as bed rails and bedside tables?
Low-level disinfection
Sterilization
Intermediate-level disinfection
High-level disinfection
Non-critical surfaces that contact intact skin require low-level disinfection to eliminate most vegetative bacteria and some viruses. High-level disinfection and sterilization are reserved for critical and semi-critical items.
What is the correct order for donning personal protective equipment (PPE) to ensure maximum protection?
Mask, gown, goggles, gloves
Goggles, gown, mask, gloves
Gown, mask, goggles, gloves
Gloves, gown, mask, goggles
The recommended sequence is gown first, then mask, eye protection, and gloves last to avoid contaminating clean equipment. This order ensures each item is applied with minimal risk of self-contamination.
When is hand hygiene required according to standard precautions?
Only before invasive procedures
Once at the start of the shift
Before and after patient contact
Only after exposure to bodily fluids
Standard precautions mandate hand hygiene before and after every patient contact, regardless of perceived risk. This practice reduces transmission of pathogens between patients.
Which of the following pathogens is primarily transmitted via the airborne route requiring airborne precautions?
Influenza virus
Mycobacterium tuberculosis
Clostridioides difficile
Norovirus
Mycobacterium tuberculosis is spread by droplet nuclei smaller than 5 microns that can remain suspended in the air. Influenza and norovirus use droplet or contact routes, and C. difficile is primarily contact-transmitted.
Which disinfection method is recommended for semi-critical medical devices like endoscopes that contact mucous membranes?
Dry heat sterilization
Sterilization using an autoclave
High-level disinfection
Low-level disinfection
Semi-critical devices require high-level disinfection to eliminate all microorganisms except high numbers of spores. Autoclave sterilization is reserved for critical items that penetrate sterile tissue.
A blood spill occurs on a countertop. Which disinfectant concentration is most appropriate for decontamination?
Pure hydrogen peroxide
70% ethanol
1:10 bleach dilution
1:100 bleach dilution
A 1:10 dilution of sodium hypochlorite (bleach) is the standard for blood spills because it provides adequate sporicidal activity. Lower concentrations or alcohol are less effective against blood-borne pathogens.
Which personal protective equipment is essential when performing an aerosol-generating procedure on a patient with suspected tuberculosis?
Cloth mask and gloves
Face shield only
N95 respirator, gown, gloves, and eye protection
Surgical mask, gloves, and gown
Aerosol-generating procedures require a fit-tested N95 respirator plus gown, gloves, and eye protection to prevent inhalation of infectious droplet nuclei. Surgical masks do not provide adequate respiratory protection.
What is the correct sequence for doffing PPE to minimize self-contamination?
Gloves, goggles, gown, mask
Gown, gloves, goggles, mask
Mask, gown, gloves, goggles
Goggles, mask, gown, gloves
Removing gloves first eliminates the most contaminated item. Next remove eye protection, then gown, and mask last to avoid touching the face with potentially contaminated hands.
When should alcohol-based hand rub NOT be used?
When hands are not visibly soiled
Before sterile procedures
When hands are visibly dirty or contaminated
After removing gloves
Alcohol-based hand rub is ineffective on visible soil or bodily fluids. In those cases, hands must be washed with soap and water before applying hand rub or after glove removal.
During a surgical procedure with high risk of sharps injury, which practice is recommended to reduce transmission risk?
Single gloving technique
Using cloth gloves
Double gloving technique
Wearing only sterile gloves
Double gloving provides an additional barrier against sharps injuries and reduces the risk of bloodborne pathogen transmission if the outer glove is breached. Single gloving offers less protection.
How often should high-touch surfaces in an intensive care unit be cleaned with a disinfectant?
Once a week
Only during monthly deep cleaning
After every patient discharge only
At least once daily or when visibly soiled
High-touch surfaces should be disinfected at least daily and immediately when visibly soiled to interrupt transmission of pathogens. Infrequent cleaning increases the risk of cross-contamination.
Which sterilization method utilizes vaporized hydrogen peroxide for low-temperature sterilization of heat-sensitive instruments?
Vaporized hydrogen peroxide sterilization
Dry heat sterilization
Steam autoclaving
Ethylene oxide gas sterilization
Vaporized hydrogen peroxide (VHP) is a low-temperature sterilization method suitable for heat- and moisture-sensitive devices. It achieves high-level microbial kill without the heat of steam autoclaving.
What is the primary goal of surveillance activities in infection control programs?
To schedule patient appointments efficiently
To sterilize all medical equipment
To monitor infection rates and detect outbreaks rapidly
To train staff in basic first aid
Surveillance in infection control is designed to track infection rates, identify outbreaks early, and guide interventions. It does not involve direct sterilization or administrative scheduling tasks.
Which process is required to achieve sporicidal activity necessary for sterilization of critical surgical instruments?
Steam sterilization under pressure
Intermediate-level disinfection with phenolics
Low-temperature chemical disinfection
High-level disinfection at room temperature
Steam sterilization under pressure (autoclaving) achieves sporicidal activity by applying moist heat at 121 - 134°C. Chemical and intermediate-level methods do not reliably kill spores on critical instruments.
Why do biofilms on medical device surfaces pose a significant challenge to disinfection processes?
They increase device temperature
They only contain dead bacteria so no risk
They form a protective matrix that shields microbes from disinfectants
They reduce microbial resistance to chemicals
Biofilms produce an extracellular polymeric matrix that prevents disinfectants from penetrating and killing embedded organisms. This protective layer increases microbial resistance to standard cleaning.
An outbreak of surgical site infections is traced back to improper linen handling. Which breach most likely contributed to the transmission?
Linen laundered at recommended temperature
Reusing soiled linens between patients
Changing linens for each patient
Clean linen stored in a closed cabinet
Reusing soiled linens between patients can transfer pathogens from one surgical area to another, leading to infections. Recommended practice is to remove and launder linens after each use.
For managing a patient with Ebola virus disease, which PPE protocol provides the highest level of protection?
Surgical mask and gloves only
Cloth gown and face shield
Powered air-purifying respirator (PAPR), impermeable suit, double gloves, and boot covers
N95 respirator, gown, and gloves
Ebola requires full-body coverage with an impermeable suit, PAPR for respiratory protection, double gloves, and boot covers to prevent any exposure to infectious fluids. Lesser PPE does not fully protect caregivers.
A portable ultrasound probe contacts mucous membranes. Which cleaning protocol should be followed after each use?
High-level disinfection with compatible chemical agent after pre-cleaning
Wiping with alcohol swab only
Low-level disinfection only
No cleaning needed as it's non-critical
Semi-critical items like probes that contact mucous membranes require pre-cleaning followed by high-level disinfection to eliminate viruses, bacteria, and fungi. Low-level methods are insufficient.
