Study Notes
General Phlebotomy Practices
- Additive tubes must be mixed immediately after removal from the holder to ensure proper blood sample integrity.
- In case of uncertain fasting status due to a recent meal, confirm with the patient's nurse before collecting specimens.
- For patients with hearing difficulties, use a normal tone but speak distinctly for clear communication.
Patient Interaction and Safety
- Always knock softly and request permission before entering a patient's room to respect privacy.
- Excessive mixing of specimens can lead to hemolysis, damaging blood cells and affecting test results.
- A large-volume tube combined with a 23-gauge needle can also result in specimen hemolysis.
Priority in Sample Collection
- STAT electrolytes should be collected first during emergencies like those in the ER, as they are urgent tests requiring immediate attention.
- If bleeding persists beyond 5 minutes after a venipuncture, notify the patient's nurse or healthcare provider for further evaluation.
Identification and Specimen Integrity
- Draw specimens only after confirming patient identification; ID bands are crucial for safe and accurate testing.
- The testing process initiates when a healthcare provider orders the test, signifying the start of sample collection protocols.
Communication and Patient Comfort
- NPO (nil per os) indicates that the patient should consume nothing by mouth before a procedure.
- Gently waking a sleeping patient before a blood draw minimizes the risk of startling them.
Types of Specimens and Collection Techniques
- Urgent specimens drawn immediately are classified as "stat".
- After two unsuccessful attempts at collecting a specimen, consult another phlebotomist for assistance.
- Avoid having patients pump their fists during vein selection, as this can negatively impact specimen quality.
Technical Procedures
- A tourniquet must be snug but comfortable, applied 3 to 4 inches above the venipuncture site to facilitate blood flow without compromising arterial circulation.
- Blood collection tubes should be labeled right after specimen collection to ensure accuracy.
- Informing a child that a procedure will not hurt may be misleading; instead, use more honest communication strategies.
Needle Insertion Techniques
- Recommended needle angles: 30 degrees or less for antecubital veins and 10 degrees or less for hand veins.
- Do not leave a tourniquet on for more than 1 minute before specimen collection to prevent complications.
Recognizing Vein Entry and Professionalism
- Blood entering the hub of the needle indicates successful entry into a vein.
- Student phlebotomists must clearly inform patients of their status as learners to maintain transparency.
- The most critical phlebotomy error is misidentifying a patient specimen, which can lead to serious consequences.
Responding to Patient Movement
- If a patient moves during venipuncture, apologize, and carefully reinsert the needle, clean the site, and proceed with the collection.
- Confirm patient identification by cross-referencing the ID band, requisition details, and the patient’s verbal confirmation to ensure accurate testing.
