Post Test 3: Correct Nursing Care for Obtaining Blood from a CVAD

The Importance of Using the Correct Syringes for CVAD Care

The nurse is preparing to obtain blood from a CVAD (Central Venous Access Device) and then change the dressing. It is crucial to ensure that the correct nursing care is provided during these procedures to maintain the functionality of the CVAD and prevent complications. One key aspect of this care is the use of the right syringes for flushing and blood drawing.

Nursing Care Options:

A) 5-mL syringe with heparin for flushing and 10-mL syringe for blood draw
B) 3-mL syringe with normal saline for flushing and 5-mL syringe for blood draw
C) 1-mL syringe with heparin for flushing and 1-mL syringe for blood draw
D) 10-mL syringe with normal saline for flushing and 3-mL syringe for blood draw

Question:

Which syringes should be used for correct nursing care when obtaining blood from a CVAD?

Answer:

The correct nursing care when drawing blood from a CVAD and changing the dressing involves using a 10-mL syringe with normal saline for flushing, and a 3-mL syringe for the blood draw.

Explanation: When drawing blood from a CVAD, it is essential to use a 10-mL syringe with normal saline for flushing and a 3-mL syringe for the actual blood draw, as stated in option D. The larger syringe provides enough volume to clear the CVAD effectively, while the smaller syringe allows for the safe and accurate collection of blood samples for testing purposes.

Proper flushing with normal saline is crucial to maintaining the CVAD's patency and cleanliness, preventing blockages and ensuring its proper function. Changing the dressing after the procedure is also important to reduce the risk of infections.
