Why do you avoid venipuncture on the same side as mastectomy?
Venipuncture is avoided on the same side as a mastectomy due to an increased risk of complications, such as lymphedema, infection, and impaired healing. The removal of lymph nodes during the procedure can lead to compromised lymphatic drainage, making the affected side more susceptible to swelling and other issues. Additionally, using the arm on the mastectomy side for venipuncture may cause discomfort and increase the risk of complications for the patient.
When is a tournique removed during venipuncture?
A tourniquet is typically removed immediately after the blood collection is completed during venipuncture. This helps to restore normal blood flow and reduces the risk of complications such as hematoma formation. It's important to avoid leaving the tourniquet on for too long, as it can cause discomfort and may affect the quality of the blood sample.
What is the name of a condition when a venipuncture site is swollen?
A condition where a venipuncture site is swollen is known as "phlebitis." This inflammation of the vein can occur due to irritation from the needle or the intravenous catheter, leading to swelling, redness, and pain at the site. If the swelling is due to fluid accumulation, it may also be referred to as "infiltration." Proper technique and care can help minimize these complications.
What is it call puncture of a vein?
The puncture of a vein is commonly referred to as venipuncture. This procedure is typically performed to draw blood for testing or to administer medications. It involves inserting a needle into a vein, usually in the arm, to access the circulatory system safely. Venipuncture is a routine practice in medical settings and requires proper technique to minimize discomfort and reduce the risk of complications.
What is meant by puncturing a venipuncture?
A venipuncture is a puncture in a vein. As when a person gives blood or has a blood test run.
How do you anchor a vein during venipuncture?
You use your thumb to keep the vein from "rolling" while doing a venipuncture.
What standard conditions must be observed during venipuncture?
See the Web Links to the left for more information about venipuncture.
What are possible complications of the human leukocyte antigen test?
Risks for this test are minimal, but may include slight bleeding from the blood-drawing site, fainting or feeling lightheaded after venipuncture, or hematoma (blood accumulating under the puncture site).
Why are the antecubital veins preferred for performing venipuncture?
The antecubital veins, primarily the median cubital vein, are preferred for venipuncture because they are typically large, superficial, and centrally located in the arm, making them easily accessible. They generally have fewer surrounding nerves and arteries, reducing the risk of complications during the procedure. Additionally, these veins often have a consistent anatomical position, enhancing the success rate of obtaining a blood sample.
Why is hemostasis after a venipuncture?
it promotes vasoconstriction
What percautions should the phlebotomist take when performing a venipuncture on a postoperative patient who had a right-sided mastectomy?
When performing a venipuncture on a postoperative patient who had a right-sided mastectomy, the phlebotomist should avoid using the right arm for blood draws to reduce the risk of complications such as lymphedema. They should also check for any signs of infection or complications in the surgical area and ensure that the patient is comfortable and informed about the procedure. Additionally, using a smaller gauge needle may help minimize discomfort. Finally, proper aseptic technique must be maintained to prevent infection.
Why is hemostasis important after a venipuncture?
it promotes vasoconstriction
