Study Notes
Chapter 7: Blood Collection Equipment, Additives, and Order of Draw
- Phlebotomy Essentials, Eighth Edition, by Ruth E. McCall is the source material
- Objectives cover equipment, supplies, evacuated tube systems (ETS), syringe systems, and blood collection additives
- General blood collection equipment and supplies include:
- A blood drawing station with a table for supplies and a special chair or bed/reclining chair
- Comfortable phlebotomy chairs with adjustable armrests to prevent falls, adjustable height for ergonomics, and availability in bariatric models.
- Handheld phlebotomy equipment carriers in various sizes suitable for STAT or emergency orders
- Phlebotomy carts which are larger and better for collecting multiple samples, and are used for "sweeps"
- Gloves must be new and non-sterile for each patient to prevent allergies and dermatitis
- Hand sanitizers and disinfectants are also necessary
- Gauze pads or cotton balls are used for pressure after collection. Avoid cotton balls, as they tend to stick.
- Slides, pens, and watches for labelling tubes and initialing forms
- Needle and sharps disposal containers for safety
- Biohazard bags for transport
- Vein-Locating devices like transillumination and infrared light can help locate veins for easier puncture
- Tourniquets are a device used to restrict blood flow to inflate veins, but not arterial flow
- Needles are sterile and disposable, for single use only, with various types like multisample and hypodermic, and winged infusion (butterfly)
- Gauge refers to the diameter of the lumen, with 21 gauge 1 ½ inch needle being most common for phlebotomy
- Safety features on tube holders should be used to prevent issues associated with needles and sharps
- Evacuated tube systems (ETS) and syringe systems use multiple tubes for collection with a single puncture and have specific components and features for safety. ETS is a closed system to prevent exposure to contaminants
- Multisample needles, tube holders, needle and holder units, and evacuated tubes are components of an ETS system
- Needle and holder units are used with both ETS and syringe systems
- Evacuated tubes utilize a vacuum to draw blood into a tube
- Additives for tubes can be anticoagulants (e.g., EDTA, citrate, oxalate, or heparin) for various tests or clot activator that causes the blood to clot
- Color coding is a consistent method to identify the presence or absence of an additive
- Expiration dates are on tube labels to ensure proper use
- NAACLS Entry Level Competencies are mentioned and addressed throughout the chapter regarding various types of additives, equipment usage, and precautions.
Chapter 8: Venipuncture Procedures
- Objectives cover venipuncture steps, patient identification, handling discrepancies, and reasons for inability to collect a sample.
- Overview looks at the process of venipuncture, types of patients, and associated challenges.
Chapter 9: Preexamination/Preanalytical Considerations
- Objectives describe preexamination/preanalytical procedures that can influence lab testing results.
- Overview describes preexamination/preanalytical phase and needed skills and considerations.
- This chapter discusses physiologic variables like age, gender, altitude, and conditions of the body as they pertain to specimen collection.
- Problem sites in collection include:
- Burns, scars, tattoos
- Damaged Veins (sclerosed, thrombosed)
- Edema
- Hematoma
- Mastectomy
- Obesity
- Paralysis
- Vascular Access Devices (IV lines, Catheter Lock, Previously Active IV Sites).
- Arterial Lines (A-lines or art-lines)
- Arteriovenous (AV) Shunt/Fistula/Grafts (including Blood Sampling Device, CVADs and their types).
- Reference ranges, Basal state, and implications of them associated with a patient's test results
- This includes Excessive Bleeding, Fainting (Syncope), Nausea and Vomiting, Petechiae, and Seizures/Convulsions, and the associated procedural errors.
- Also describes various complications:
- Hematoma formation and bruising,
- Iatrogenic Anemia,
- Infection,
- Nerve Injury,
- Reflux of Additive, and
- Vein Damage
- Issues related to specimen quality:
- Hemoconcentration, and hemolysis.
- Specimen Contamination
Chapter 10: Capillary Puncture Equipment, Principles, and Procedures
- Capillary puncture involves collection drops of blood from a small incision in a capillary bed.
- Equipment required includes lancets (finger and heel)
- Equipment for microcollection containers/microtubes, hematocrit tubes, warming devices, and blood gas equipments.
- General Capillary Puncture steps, includes:
- Receiving, reviewing, and accessioning the test request
- Greeting and identifying the patient
- Explaining the procedure
- Verifying collection requirements and identifying sensitivities
- Sanitizing the hands and applying gloves
- Positioning the patient
- Selecting the puncture site
- Warming the site if needed
- Preparing the equipment
- Positioning the lancet
- Performing the puncture, and pulling the blood
- Discarding the lancet, and securing the site
- Labeling the tubes appropriately.
- Transporting the blood to the laboratory.
- Detailed descriptions of capillary puncture procedures for different patient types(adults, infants, children)
- Procedures for preparing blood smears (routine blood smear preparation, thick blood smear preparation), for capillary blood gas (CBG) specimens, and for handling newborn screening procedures.
- Identifying, explaining, and listing tests that cannot be performed on capillary specimens.
- Potential complications of the technique and precautions.
