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.

Do you draw below or above an IV?

If there is not an alternate vein to draw, the venipuncture should be performed distal to (below) the hematoma. opposite arm, then blood should be drawn from BELOW (distal to) the IV. contaminated based on the test results.

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.

Is it safe to collect a specimen above an IV?

If an IV is in place, samples may be obtained below but NEVER above the IV site. Do not obtain specimens from an arm having a cannula, fistula, or vascular graft.

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.

Which of the following tubes should be drawn first?

The order of draw is based on CLSI Procedures and Devices for the Collection of Capillary Blood Specimens; Approved Standard – Sixth Edition, September 2008. This standard recommends that EDTA tubes be drawn first to ensure good quality specimen, followed by other additive tubes and finally, serum specimen tubes.

What is the proper order of the draw?

The correct order of draw follows: Blood culture tube or bottle. Sodium citrate tube (eg, blue closure) Serum tubes, including those with clot activator and gels (eg, red, red-speckled, gold closures)

Can you draw blood from central line?

Blood draws via central line catheters may be performed only by RNs trained in central line. 4. This procedure shall be done using aseptic technique.

Can you draw labs off a midline?

Also, routine blood draws are not advised from a midline catheter, whereas they can be used from the other types of venous catheters. It is possible to draw from a midline catheter if very gentle pressure is applied and a specific technique is used.

When drawing blood below an IV site notify the nurse to stop the IV for at least?

Draw the patient promptly at the 5 minute mark. If you are drawing below the IV site you will need to shut the IV pump off for 2 minutes.

Which sites should you avoid for venipuncture?

Do not use the tip of the finger or the center of the finger. Avoid the side of the finger where there is less soft tissue, where vessels and nerves are located, and where the bone is closer to the surface. The 2nd (index) finger tends to have thicker, callused skin.

What needle size would not be appropriate to draw blood with?

18 Gauge Needles 18g needles are not used for routine blood draws. A needle this large is used for donating more substantial quantities of blood that require a faster blood flow rate, such as blood donor units and therapeutic phlebotomy.

Can you draw blood without a tourniquet?

Performing venipunctures without tourniquets is not an option. Constriction of the circulation causes veins to distend as they fill up with blood that can no longer circulate. Distended veins are easier to palpate and access.

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.

What color tubes for lab draws?

How can I remember my phlebotomy tubes?

This knowledge is what separates a good phlebotomist from an amazing phlebotomist. The best way to always remember tubes is by additives. This way, no matter how many times a hospital may change the color of the tubes, the additives will always remain the same.

Does order of draw matter?

In the era of lyophilized anticoagulants, order of draw is no longer important. Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. … Modern lab equipment can tell the difference between K from the EDTA tube and K from the patient, so order of draw is no longer important.

How many labs can one tube draw?

ALL OF THIS PAGE CAN SHARE A TUBE UP TO ABOUT 12 TESTS.

Why is the order of draw so 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.

Can you draw blood from a 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.

Is a midline a PICC?

Q: What is the difference between a PICC and a midline? Peripherally inserted central catheters (PICC), which are central lines, and midline catheters, which are peripheral lines, are two types of vascular access devices (VAD) that are used frequently and are often confused with one another.

Can you draw labs from a PICC line?

Frequent blood draws: PICC lines can be useful for drawing blood repeatedly, especially if you do not tolerate blood draws well yet require ongoing monitoring through blood tests.

Do you flush a central line before drawing blood?

To maintain patency, flush all CVCs before and after access and infusion. You can draw blood from a CVC using the discard method with direct Vacutainer connection or a syringe or using the push-pull method with a syringe.

Can you draw blood from a single lumen PICC?

A single lumen PICC has one tubing and one cap on the end. A double lumen PICC has two separate tubings and two caps. A PICC is used to give medications, fluids and IV nutrition. If the PICC is big enough, it can be used to draw blood.

Why do PICC lines stop drawing blood?

Excessive force could cause a flexible PICC to temporarily collapse and occlude the backflow of blood. On a peripheral vein, you could be pulling the vein wall over the catheter lumen as in this drawing.

Can we draw blood from cannula?

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.

Can you draw labs during blood transfusion?

Q: Can I draw a blood specimen while the patient is being transfused? A: If a patient is receiving a blood transfusion, blood specimens may be collected during the infusion from the other arm where blood is not being infused.

Can you draw PTT from arterial line?

Conclusion: We recommend that when drawing prothrombin time and activated partial thromboplastin time samples from an arterial line, a 5.3-mL discard volume be used.

Do you stop heparin drip before drawing PTT?

When we must draw from the arm with fluids infusing, our policy has always been that the RN must pause the IV. If the IV is in the other arm, we do not ask the nurses to pause the infusion no matter what is being infused or what is being drawn.

What happens if IV missed vein?

If the catheter becomes dislodged or moves out of the vein, the fluid that was being infused through it could now leak into surrounding tissue. When that occurs, it is called an IV infiltration. An IV line can cause an infiltration without a nurse or doctor being negligent.

What happens when a vein collapses during a blood draw?

A collapsed vein is a blown vein that has caved in, which means that blood can no longer flow freely through that vein. Blood flow will resume once the swelling goes down. In the meantime, that vein can’t be used. If the damage is severe enough, a collapsed vein can be permanent.
