Which of the following is the first step in the blood collection procedure?
Phlebotomy, the practice of drawing blood from a vein, is a proficiency that all nurses should learn in their career. While not commonly taught in nursing school programs, many recommend that nursing students take extra courses in how to take blood to hone this skill. Show
Obtaining blood samples, either via a venous stick or from a central line, is a critical nursing skill. Phlebotomy is essential for a variety of medical diagnoses, procedures, and tests. Without proper specimens, unhelpful or even harmful medical treatment could happen. Nursing schools do not teach this skill due to legality issues. Students should study venipuncture in books and watch licensed nurses in clinical settings perform this task. In doing so, this will enable students to learn basics prior to graduation. Even though most hospitals do have phlebotomy teams, it is still critical for nurses to learn these skills in order to provide the best patient care. In fact, the majority of intensive care units require their nurses to possess these skills. Phlebotomy teams generally only make rounds at specific times in hospital settings, therefore, if a lab test is ordered immediately it could be the responsibility of the nursing staff to draw the specimen. How to Learn How to Draw BloodThe practice of phlebotomy is not something that can strictly be learned from watching videos or reading a how-to guide but something that must be practiced repeatedly in a controlled environment with other trained professionals. It’s important to speak to your supervisor to learn the steps in order to become certified in your hospital. Each healthcare system has its own requirements prior to nurses performing blood draws. The World Health Organization's Blood Draw GuidelinesThe World Health Organization’s (WHO) best practice guidelines for blood draws include the following:

Step 1: Identify The VeinThe first step in drawing blood correctly is to identify the appropriate veins to puncture. For adult patients, the most common and first choice is the median cubital vein in the antecubital fossa. Commonly referred to as the antecubital or the AC it can be found in the crevice of the elbow between the median cephalic and the median basilic vein. This is an extremely large vessel and if stuck properly can yield excellent blood results. Some health care settings may insert blood drawing peripheral intravenous catheters into this vessel for frequent blood draws. For novice phlebotomists, this vein is the first choice because it is close to the skin’s surface and tends not to roll when punctured. Furthermore, it has a low risk of damaging surrounding nerves, arteries, and tendons versus other veins in the hands. Learning the anatomy of the main veins and arteries in the body is essential to becoming competent in phlebotomy. If the antecub has already been accessed there are great options for venipuncture. Other commonly used veins include:

Step 3: VenipunctureAfter assembling the appropriate equipment, follow the next steps to perform a proper venipuncture. Once again, please be aware that these are only guidelines for blood draws and nurses should consult with the appropriate hospital personnel regarding performing this procedure on patients. Additionally, these steps only apply to the adult and pediatric population and not neonates.
Don’t be discouraged if at first, you don’t access the vein. Venipuncture is a skill that takes time and practice to master. Always remember to ask for help from seasoned nurses and seize opportunities to practice your skills.
