Final answer:
The CPCT should apply pressure to the site, elevate the affected limb, and possibly apply a cold pack, followed by monitoring and documentation of the hematoma.
Step-by-step explanation:
If a Certified Patient Care Technician (CPCT) observes a hematoma developing at the site of a venous blood draw, the appropriate action would be to apply pressure immediately to the site after removing the needle. If bleeding does not stop, it’s also helpful to elevate the limb and apply a cold pack to reduce swelling. The CPCT should monitor the patient for signs of increased pain or swelling, or change of color in the affected limb which may indicate a more serious complication. Proper documentation of the incident and reporting it to a supervisor or the responsible healthcare professional is also essential for patient safety and continuity of care. Additionally, the CPCT should consider reviewing their blood draw technique to prevent similar issues in the future, as hematomas can occur due to improper technique or other factors such as fragile veins or the patient’s medication.
