1

What is the correct flushing preparation and schedule for maintaining central venous catheter patency?

Plain saline only; flush once daily to avoid overuse
Heparinized saline at 1,000 IU in 100 mL; flush before dressing change
Heparinized saline at 5,000 IU in 500 mL; flush each lumen immediately after insertion and every 8–12 hours if idle
Dextrose solution; flush only after medication administration

2

During a routine line check, a nurse observes that the patient’s catheter hub was left open for several seconds after disconnecting the infusion set. What complication could this most directly lead to?

Hematoma at insertion site
Arrhythmia from tip migration
Catheter-related infection
Air embolism

3

Which statement best explains why patients should remain supine during all line manipulations?

Supine position increases venous pressure, reducing risk of air entry
Supine position decreases pain during catheter movement
Supine position improves arterial flow for blood return testing
Supine position allows better visualization of the insertion site

4

During a dressing change, a clinician notes redness and a small amount of purulent discharge at the catheter insertion site. What is the issue here?

The dressing needs to be reinforced with additional gauze
The line should be flushed with antibiotics to prevent further spread
The site should be cleaned and monitored for the next 24 hours
The findings suggest a catheter-related infection that requires immediate removal and culture

5

In a low-resource clinic, transparent dressings are unavailable. What is the safest adaptation for maintaining catheter security and inspection?

Use sterile gauze with adhesive tape and inspect more frequently
Cover the site completely with multiple gauze layers to prevent air exposure
Skip dressing changes to avoid repeated manipulation
Replace the line daily to prevent infection
