Q: In a patient with an IV catheter, you may draw from the same arm that has the IV catheter if . . . You may only draw above the IV. You can draw below the IV with a tourniquet between the IV site and the draw site. You can only draw from the opposite arm.
Why can’t you draw blood above an IV site?
Blood that is drawn from a vein that has an intravenous (IV) line may be diluted by the IV fluid. This can ultimately affect the accuracy of the blood test results. Therefore, an arm containing an IV should not be used to draw blood specimens if it can be avoided.
How do you insert an IV step by step?
How to Insert an IV Step 1: Gather Supplies. Gather supplies including: Step 2: Examine. Examine the individual’s veins in the selected area. Step 3: Apply Tourniquet. Step 4: Cleanse. Step 5: Replace Tourniquet. Step 6: Prepare Needle for Insertion. Step 7: Insertion. Step 8: Release Tourniquet.
Where should an IV be placed?
The most common site for an IV catheter is the forearm, the back of the hand or the antecubital fossa. The catheters are for peripheral use and should be placed where veins are easy to access and have good blood flow, although the easiest accessible site is not always the most suitable.
Do you draw above or below an IV?
You may only draw above the IV. You can draw below the IV with a tourniquet between the IV site and the draw site. You can only draw from the opposite arm. The available data suggest that the second and third options are equally appropriate.
When drawing blood above an IV line you must?
The only coagulation test that can be drawn above an IV site is the prothrombin time. The infusion should be turned off for 10 minutes before obtaining this coagulation test. (A discard tube is still necessary.) For blood cultures, there is no need to discard any blood prior to filling the culture tubes/bottles.
Can you draw blood from peripheral IV?
A. Blood samples should NOT be drawn during IV starts or from established IV catheters except for patients on thrombolytics (to reduce number of sticks), or in an emergency. B. Peripheral lab samples should be obtained using a straight needle and either the Vacutainer or syringe method.
What is the order of draw?
The “Order of Draw” is designed to eliminate the possibility of cross contamination that may result in erroneous results. It is based on CLSI Procedures for Collection of Diagnostic Blood Specimens by Venipuncture; Approved Standard Sixth Edition, October 2007.
How do you do IV cannulation?
Procedure Steps Introduce yourself to the patient. Sanitise your hands using alcohol cleanser. Re-check the vein. Clean the patients skin with the alcohol wipe. Remove the needle cover. Flashback of blood is seen in the hub. Advance the rest of the cannula into the vein. Remove the needle.
In which position should you place a patient for peripheral IV catheter insertion?
Needle insertion follows at a shallow angle of fewer than 45 degrees through the skin, aiming towards the vein and is advanced slowly until a “flash” of blood appears in the chamber.
What is the first step in the insertion of a peripheral IV line?
21 Cards in this Set The primary function of veins is to carry blood from.. the body to the heart. What is the first step in the insertion of a peripheral IV line or saline lock? Obtain a physician order. The purpose of valves in veins is to prevent backflow of blood as it travels through the body.
Where does an IV go in your arm?
It will usually be a vein under the skin on the back of the hand or the inside of the arm between the wrist and elbow. The provider may tie a tourniquet (a wide plastic band kind of like a rubber band) around the arm to increase pressure. The tourniquet makes it easier to feel vein.
Which vein is the first choice for venipuncture?
The antecubital area of the arm is usually the first choice for routine venipuncture. This area contains the three vessels primarily used by the phlebotomist to obtain venous blood specimens: the median cubital, the cephalic and the basilic veins.
Do you keep tourniquet on when drawing blood?
Once sufficient blood has been collected, release the tourniquet BEFORE withdrawing the needle. Some guidelines suggest removing the tourniquet as soon as blood flow is established, and always before it has been in place for two minutes or more.
Can you take blood from a peripheral line?
Guidelines recommend blood samples from peripheral intravenous cannula be taken only on insertion. Anecdotal evidence suggests drawing blood from existing cannulas may be a common practice.
How do you draw peripheral blood?
A tourniquet is placed around the upper arm to allow blood to collect in the veins, making the veins easier to find and puncture. The skin is then sanitized, usually the inside of the elbow. A sterile needle is then inserted into a vein, and attached to a collection container, typically a tube.
What is peripheral Venepuncture?
As previously stated, peripheral IV cannulation involves inserting an IV cannula into a peripheral vein. Primarily the veins of the hand or forearm are used. Venepuncture involves inserting a needle into the peripheral veins, for the purpose of aspirating blood.
What order do you draw blood tubes?
The recommended order of draw for plastic collection tubes is: First – blood culture bottle or tube (yellow or yellow-black top) Second – coagulation tube (light blue top). Third – non-additive tube (red top) Last draw – additive tubes in this order:.
Why is order of draw important?
The order of draw is recommended for both glass and plastic venous collections tubes when drawing multiple specimens for medical laboratory testing during a single venipuncture. The purpose is to avoid possible test result error due to additive carryover. All additive tubes should be filled to their stated volumes.
What color tube for lab draws?
Blood Collection Tubes Tube cap color Additive Red or gold (mottled or “tiger” top used with some tubes) Serum tube with or without clot activator or gel Green Sodium or lithium heparin with or without gel Lavender or pink Potassium EDTA Gray Sodium fluoride, and sodium or potassium oxalate.
