Question 1

Before administering chemotherapy through a port-a-cath, the nurse aspirates and gets no blood return. What is the MOST appropriate next step?

Accepted Answer

Hold the chemotherapy and notify the provider to assess catheter function

Answer

Lack of blood return from a port-a-cath before chemotherapy administration requires provider notification and catheter assessment to prevent extravasation of vesicant drugs.

Question 2

Which type of central venous access device is MOST appropriate for a patient requiring 6 months of intermittent chemotherapy infusions?

Accepted Answer

Implanted port (port-a-cath)

Answer

An implanted port is the preferred long-term vascular access device for intermittent chemotherapy due to its durability, low infection risk, and patient comfort.

Question 3

A patient with a PICC line develops pain, erythema, and a palpable cord along the arm. What complication does the nurse suspect?

Accepted Answer

Thrombophlebitis

Answer

Pain, redness, and a palpable cord along the vessel indicate thrombophlebitis, a known complication of PICC lines requiring immediate evaluation.

Question 4

What is the correct flushing sequence for a positive pressure implanted port after chemotherapy administration?

Accepted Answer

Saline → heparin → clamp while maintaining positive pressure

Answer

The correct sequence is saline flush followed by heparin lock while maintaining positive pressure to prevent blood backflow and clot formation in the port.

Question 5

Which chemotherapy agent requires extra caution with peripheral IV administration due to its extreme vesicant properties?

Accepted Answer

Vincristine

Answer

Vincristine is a potent vesicant that causes severe tissue necrosis on extravasation, requiring central venous access and vigilant infusion monitoring.
