Central Venous Access Devices Practice Tests

Caring for a central line requires more than knowing the steps—it requires the kind of presence and vigilance nurses build through experience. These questions help you practice the everyday decisions that keep CVADs safe: assessing the site, maintaining sterile technique, preventing CLABSI, verifying blood return, and recognizing when something about the line—or the patient—just doesn’t feel right.

Scenarios feel like real shifts: a PICC line without blood return during morning labs, a tunneled catheter dressing that’s starting to lift, a port that won’t flush, or a TPN infusion that suddenly alarms. You’ll decide when to troubleshoot, when to stop everything, and when the risk is high enough to call the provider immediately. The goal is not just technical accuracy, but protecting the patient from silent complications like air embolism, thrombosis, and catheter migration.

Expect select-all items on flushing protocols, heparin vs. saline locks, compatibility considerations, clamp and cap management, sterile dressing changes, and red flags such as swelling, sudden pain, tachycardia, or difficulty flushing.
