1. What is the preferred site for central venous catheter insertion to reduce
the risk of infection?
a. Femoral vein
b. External jugular vein
c. Subclavian vein
d. Brachial vein
The subclavian vein is preferred due to its lower infection risk compared
to femoral access.
2. Which of the following is the best method to confirm correct placement of
a central venous catheter?
a. Flushing with saline and checking for resistance
b. Measuring catheter length
c. Chest X-ray
d. Observing blood return
Chest X-ray is the gold standard to confirm central line tip placement
and avoid complications like pneumothorax.
, 3. What is the primary risk of infusing hypertonic solutions via a peripheral IV
line?
a. Air embolism
b. Phlebitis and vein damage
c. Catheter occlusion
d. Infiltration
Hypertonic solutions can irritate peripheral veins, causing inflammation
and damage.
4. When is a peripherally inserted central catheter (PICC) preferred over a
traditional central line?
a. For emergency fluid resuscitation
b. When long-term IV therapy is needed
c. When the patient has hypotension
d. For intraosseous infusions
PICC lines are ideal for long-term therapy such as antibiotics or
chemotherapy.
5. Which solution is appropriate for flushing a central venous catheter?
a. 10 mL Dextrose 5%
b. 10 mL 0.9% Sodium Chloride
c. Heparin 5000 units/mL
d. Sterile water
Normal saline is recommended for routine flushing to maintain patency.
, 6. What should be done if resistance is met during flushing of a central line?
a. Force the flush
b. Reposition the patient
c. Remove the catheter
d. Stop and assess for occlusion
Flushing against resistance can cause catheter rupture or embolism;
assessment is critical.
7. What is the recommended frequency for changing IV tubing on continuous
infusions?
a. Every 96 hours
b. Every 72-96 hours
c. Every 48 hours
d. Every 24 hours
Tubing for continuous infusions should be changed every 72-96 hours to
reduce infection risk.
8. What is the initial action when extravasation of a vesicant is suspected?
a. Elevate the limb
b. Stop the infusion immediately
c. Apply a warm compress
d. Inject antidote immediately
Stopping the infusion prevents further tissue damage from the vesicant
drug.
