Which decontamination method is required for flexible bronchoscopes between patient uses?
Answer: High-level disinfection (e.g., glutaraldehyde or automated endoscope reprocessor)
Flexible bronchoscopes are semi-critical items requiring high-level disinfection to eliminate all microorganisms except bacterial spores.
According to the Spaulding classification, a laryngoscope blade used for intubation is classified as:
Answer: Semi-critical
Laryngoscope blades contact mucous membranes and are classified as semi-critical items requiring at minimum high-level disinfection.
A cluster of MRSA infections occurs in the ICU. After implementing contact precautions, which additional measure is most likely to identify the source?
Answer: Environmental cultures of high-touch surfaces
Environmental cultures of high-touch surfaces can identify MRSA reservoirs and guide targeted cleaning in outbreak investigations.
In ICU patients, subglottic secretion drainage (SSD) endotracheal tubes primarily prevent VAP by which mechanism?
Answer: Removing pooled secretions above the cuff that otherwise microaspirate
SSD tubes have a port above the cuff that continuously or intermittently aspirates secretions, preventing their microaspiration into the lower airways.
Which personal protective equipment (PPE) is required when caring for a patient with confirmed pulmonary tuberculosis?
Answer: Fit-tested N95 respirator, gloves, gown, and eye protection in a negative-pressure room
Pulmonary TB is transmitted by airborne droplet nuclei; a fit-tested N95 or higher respirator and negative-pressure room are mandatory.
What is the recommended maximum duration of peripherally inserted central catheter (PICC) dwell before mandatory replacement to reduce infection risk?
Answer: There is no evidence-based time limit; replace only if clinically indicated
Current CDC guidelines do not recommend routine scheduled replacement of PICCs; catheters should be removed only when clinically indicated.
During a confirmed outbreak of norovirus in the ICU, which disinfectant is most appropriate for environmental decontamination?
Answer: Sodium hypochlorite (bleach) at ≥1000 ppm
Norovirus is resistant to many common disinfectants; sodium hypochlorite at ≥1000 ppm (0.1%) is effective against non-enveloped viruses.
