Difficulty: HardPharmacological and Parenteral Therapies

A nurse is preparing to access a client's implanted venous access device (port) using a non-coring needle to administer intravenous chemotherapy. The nurse has gathered the necessary supplies, explained the procedure to the client, and performed hand hygiene. Arrange the following steps in the correct order to access the device safely.

  1. 1Don a surgical mask, instruct the client to turn their head away from the insertion site, and don sterile gloves.
  2. 2Cleanse the skin over the port site with a chlorhexidine applicator using friction and allow it to air dry completely.
  3. 3Immobilize the port securely between the thumb and index finger of the non-dominant hand.
  4. 4Insert the non-coring needle firmly at a 90-degree angle through the skin and septum until the needle hits the back of the port.
  5. 5Aspirate gently with an attached syringe to confirm a blood return.
  6. 6Flush the device with 10 mL of sterile normal saline.

Answer

The correct sequence for accessing an implanted venous port is: donning masks and sterile gloves, cleansing the site with chlorhexidine, immobilizing the port, inserting the needle at a 90-degree angle, aspirating for blood return, and finally flushing with normal saline.
Accessing an implanted port requires strict sequential adherence to sterile technique and safety verification. The nurse must first protect the site from respiratory droplets (masks) and contact (sterile gloves). Disinfection with chlorhexidine follows, requiring complete air drying. Once sterile, the nurse stabilizes the port to prevent movement and inserts the non-coring needle at a 90-degree angle to avoid damaging the septum. Before injecting any fluid, placement must be verified by aspirating for blood return. Only after confirming a blood return can the nurse safely flush the line with saline to establish patency.

Step-by-Step Solution

1
Don a surgical mask, instruct the client to turn their head away from the insertion site, and don sterile gloves.
A sterile field is established and droplet contamination is prevented.
Central line-associated bloodstream infections (CLABSIs) are a severe risk; maximum barrier precautions are required before exposing the site.
2
Cleanse the skin over the port site with a chlorhexidine applicator using friction and allow it to air dry completely.
The insertion site is disinfected.
Chlorhexidine requires friction to penetrate the epidermis and must air dry to exert its full chemical bactericidal effect.
3
Immobilize the port securely between the thumb and index finger of the non-dominant hand.
The port is isolated and stabilized.
Implanted ports are located in subcutaneous pockets and can move; stabilization is necessary for an accurate puncture.
4
Insert the non-coring needle firmly at a 90-degree angle through the skin and septum until the needle hits the back of the port.
The needle is correctly seated inside the port reservoir.
A 90-degree angle with a specialized Huber needle prevents slicing (coring) the silicone septum, which could cause the port to leak.
5
Aspirate gently with an attached syringe to confirm a blood return.
Intravascular placement is verified.
Confirming blood return is the primary method to ensure the catheter tip has not migrated out of the superior vena cava and the line is not occluded.
6
Flush the device with 10 mL of sterile normal saline.
The catheter is cleared and patency is physically confirmed.
Flushing pushes the residual blood into the circulation, prevents clotting in the catheter, and allows the nurse to monitor for extravasation.
