Stent inventory in the cardiac cath lab is best managed using which tracking system to ensure sterility and prevent expired product use?
Answer: First-in, first-out (FIFO) with lot number tracking
FIFO inventory management with lot number and expiration date tracking ensures oldest stock is used first and expired implants are removed from service.
A cath lab staff member receives 4.5 mSv of occupational radiation dose in a single quarter. This exceeds which regulatory threshold?
Answer: Annual occupational whole-body effective dose limit of 5 mSv/quarter warning level
The NRC annual occupational whole-body limit is 50 mSv/year; quarterly monitoring at 1.25 mSv/quarter is the action level, and 4.5 mSv/quarter warrants immediate investigation.
Which quality indicator best reflects the technical success of percutaneous coronary intervention (PCI)?
Answer: Residual stenosis <20% with TIMI 3 flow post-PCI
Angiographic success after PCI is defined as residual stenosis < 20% with TIMI grade 3 (normal) flow in the target vessel.
A defibrillator in the cath lab must be checked with a test shock log at minimum:
Answer: Daily, before the first case
Defibrillators used in procedural areas must undergo a daily operational check before the first case to confirm readiness for emergencies.
Which document must be completed and retained for each fluoroscopic procedure in the cath lab to comply with Joint Commission radiation dose standards?
Answer: Radiation dose record including DAP or cumulative air kerma
TJC and state regulations require documentation of patient radiation dose (dose area product or cumulative air kerma) for all fluoroscopy-guided procedures.
Hemostasis devices such as closure plugs and suture-mediated closure systems are single-use items primarily because:
Answer: Reprocessing cannot ensure sterility or structural integrity for vascular closure
Single-use vascular closure devices cannot be reliably resterilized to maintain structural integrity needed to achieve hemostasis, creating patient safety risk if reused.
