Infection Control and Patient Safety
Asepsis
Know the hierarchy: hand hygiene, skin antisepsis with appropriate agent and dry time, maximal sterile barriers for central insertion, and sterile technique for maintenance. Scrubbing the hub before every access and using sterile dressing changes at defined intervals reduce bloodstream infection risk. Understand that dry time is part of antisepsis, not an optional step.
Safety systems
Patient identification, site marking where applicable, time-out, and informed consent are safety processes, not paperwork. Sharps safety, needlestick reporting, and post-exposure protocols are testable. Know the difference between standard precautions and transmission-based precautions, and when each applies.
Traps
Questions present a busy clinical scenario and ask what may be omitted - the answer is rarely a safety step. Another trap is confusing cleaning with disinfection with sterilization, or assuming gloves replace hand hygiene. Also watch for questions that reward speed over asepsis; the correct answer usually preserves the sterile sequence.
Rule of thumb
If a step protects the patient from infection or misidentification, it is never the correct thing to skip.
Worked example
During a busy shift a clinician wants to skip the hub scrub because the port looks clean. The correct reasoning is that visible cleanliness does not equal asepsis; the scrub is required before access regardless of appearance.
