The foot is usually a last resort. You should always have a doctors order before attempting to draw from the feet. There is more risks involved with infection etc. especially in diabetic patients.

How long should pressure be applied after venipuncture?

Pressure should be applied for about 1-2 minutes after venipuncture to ensure the bleeding stops and to prevent hematoma formation. It is important to apply firm pressure directly over the venipuncture site to aid in the formation of a clot and promote proper healing.


What are the three methods of venipuncture?

The three methods of venipuncture are vacuum method (using a vacuum tube system to collect blood), syringe method (using a syringe to manually draw blood), and butterfly method (using a small butterfly needle for difficult veins or sensitive patients).


When anchoring a vein for venipuncture why is it inadvisable to place one finger above the venipuncture site?

There are two reasons for this first is for safety. If the patient pulls the arm back when the needle is inserted the needle may recoil as it comes out of the arm, springing back into your finger. Also there is the possibility of contamination of the site that you just cleaned.


Why does the needle need to be held steady during a venipuncture procedure?

Holding the needle steady during a venipuncture procedure helps to minimize the risk of causing tissue damage or injury to the veins. It also ensures that the needle penetrates the vein smoothly and accurately, preventing unnecessary pain or discomfort for the patient.


During the venipuncture procedure the tourniquet should not remain on the patient's arm for more than how long?

According to CLSI the tourniquet should not be left on for more than a minute. If a suitable vein has not been found, remove the tourniquet, leave it off for two minutes, then reapply the tourniquet to look for suitable veins and/or perform the venipuncture.
