Study Notes

Patient Considerations During Procedures

Patients in wheelchairs should ensure safety and comfort, with appropriate support during the procedure.
Careful selection of vein location is crucial for venipuncture in elderly patients to minimize complications and ease of access.

Venipuncture Techniques for Elderly Patients

Firm anchoring of the vein is essential to prevent rolling and ensure a successful draw, particularly in fragile veins common in elderly patients.
Avoid vigorous cleaning motions when preparing the venipuncture site to prevent bruising or vein damage.
Note that bleeding may take longer to stop in elderly patients due to age-related factors, requiring careful monitoring.

Treatment Approaches for Elderly Patients

Phlebotomists should treat elderly patients with patience and gentleness to establish trust and ensure comfort during procedures.

Dialysis Patient Considerations

Preserving veins in the dorsum of the hands for dialysis patients is important to maintain access points for future treatments.
Home care phlebotomists differ by delivering services in the patient's home rather than clinical settings.

Long-term Care and Hospice

Elderly individuals may require long-term care services due to chronic illnesses, disabilities, or declining health.
The primary goal of hospice care is to enhance quality of life for terminally ill patients and provide support for their families.

Venipuncture Site Selection

Patients on dialysis may request a specific venipuncture site to avoid damage to existing access points.

Assisted Living and Patient Care

Assisted-living services are provided in residential facilities that offer support for daily activities while promoting independence.

Latex Allergy Precautions

Ensuring all equipment in the room is latex-free is crucial to prevent allergic reactions in patients with latex allergies.

Recommended Patient Positioning

Outpatients should be seated comfortably during venipuncture to reduce anxiety and promote successful access.

Managing Patient Reactions

If a patient is prone to fainting, positioning them lying down can help prevent falls or injuries during the procedure.
For patients with sensitive skin, a looser tourniquet application is advisable to avoid irritation.

Tourniquet Placement Guidelines

The tourniquet should be placed approximately 3-4 inches above the intended puncture site, ensuring adequate venous engorgement without excessive pressure.
When tying the tourniquet, ends should point towards the patient's heart for effective tightening.

Venipuncture Site Preparation

Quickly release the tourniquet once the needle is inserted to avoid prolonged venous constriction and discomfort.
Cleaning the venipuncture site with 70% Isopropyl alcohol helps reduce infection risk by effectively sterilizing the area.

Post-Cleaning Protocols

Avoid using unsterile gauze, or blowing on the venipuncture site post-cleaning as this can introduce contaminants.

Venipuncture Equipment Selection

Factors influencing the choice of system, needle size, and tube volume include the patient’s condition and specific test requirements.
After selecting an appropriate tube for an Evacuated Tube System (ETS), ensure secure attachment to prevent spills.

Preparation and Handling of Blood Specimens

With a Winged Infusion Set (Butterfly), ensure the needle is prepared correctly for smooth insertion.
A routine blood film or smear preparation is crucial for diagnostic assessments of blood samples.
Thick blood smear preparations are used for better visualization of parasites or abnormal cells.

Pediatric Blood Collection Techniques

For infants and small children, capillary blood gas specimens should be collected using gentle punctures to minimize trauma.
Handle bilirubin specimens with care, protecting them from light exposure to prevent degradation of the sample.

Specimen Labeling Requirements

Accurate specimen labeling includes essential information such as patient name, date of collection, and type of test to prevent mix-ups.

Malaria Diagnosis

An elevation of atypical lymphocytes is indicative of malaria and assists in diagnosis.
