A nurse is initiating IV therapy for a client who had a right-sided mastectomy.
In which of the following locations should the nurse place a catheter?
A.
Most proximal site.
B.
Left arm.
C.
Wrist.
D.
Cordlike vein.
E.
Cordlike vein.
The Correct answer and Explanation is:
The correct answer is B. Left arm.
When initiating intravenous (IV) therapy for a client who has undergone a right-sided mastectomy, it is crucial for the nurse to avoid using the arm on the side of the mastectomy. In this case, the right arm should not be used due to potential complications such as lymphedema.
Rationale:
- Lymphedema Risk: A mastectomy, particularly when it involves the removal of lymph nodes (such as in an axillary lymph node dissection), disrupts the lymphatic drainage system. This can lead to lymphedema, which is a painful and chronic swelling caused by the accumulation of lymphatic fluid. The use of IV therapy, blood pressure cuffs, or blood draws on the side of the mastectomy increases the risk of lymphedema, as these procedures can cause trauma or pressure that worsens fluid retention.
- Left Arm Consideration: To prevent lymphedema, it is best to initiate IV therapy in the left arm for clients with a right-sided mastectomy. The left arm is unaffected by lymph node removal, thus reducing the risk of complications. IV catheters should be placed in the most appropriate vein in this arm.
- Avoiding Other Sites:
- Most Proximal Site (A): While using the most proximal site (closer to the body) is sometimes recommended for other reasons (such as in trauma or emergency situations), it is still crucial to avoid the side of the mastectomy.
- Wrist (C): The wrist is not an ideal location for IV catheter insertion due to the proximity of nerves and the risk of patient discomfort.
- Cordlike Vein (D & E): A cordlike vein is indicative of thrombosis or venous scarring, which makes it unsuitable for IV therapy. Inserting a catheter in such a vein increases the risk of complications like infiltration or phlebitis.
Conclusion:
When initiating IV therapy in a client with a right-sided mastectomy, the left arm is the safest location for catheter placement to avoid the risk of lymphedema and other complications.
