Venipuncture Flashcards
Defined as the process of collecting or “Drawing” blood from a vein. It is the most
common way to collect blood in the laboratory.
VENIPUNCTURE
There are two ways of collection,
open system and the closed system
There are two ways of collection,
the open system and the closed system, as follows:
•BY SYRINGE
•BY EVACUATED TUBE SYSTEM
•BY CAPILLARY
Pre-analytical procedures
- PATIENT REGISTRATION
- REQUESTS FOR TESTING
is a routine process during which data are collected that creates a patient record
for the specific individual who is being admitted to the facility, or has arrived for testing at the
specimen collection center.
Registration
Patient’s Identity includes:
-Full name
-Address
-Date of Birth
-Proof of ID
-Sex
The process typically involves assignment of a ____________ which will appear on
all test requests and specimen labels for that patient.
patient-specific identifier
Typically, a physician or other qualified healthcare professional requests laboratory
testing; the exceptions are certain
rapid tests that can be purchased and performed at
home by consumers and blood specimens requested by law enforcement officials that
are used for evidence.
Test requests may be
manual, computerized or barcoded
Required Requisition Information
Ordering healthcare provider or another
authorized person’s name
• Patient’s full name (first, last, and middle
name or initial if applicable or available)
• Patient-specific identifier (e.g., inpatient
medical record number)
• Patient’s sex
• Patient’s date of birth or age (per facility
policy)
• Room number and bed (if inpatient)
• Test(s) that are to be performed
• Collection site, if appropriate
• Date test is to be performed (and time if
applicable)
• Test status (e.g., timed, fasting, priority)
•Other relevant information and
instructions (e.g., special
precautions like latex sensitivity)
• Billing information and ICD-10 codes (if
outpatient)
allow for fast, accurate processing, and their use has been shown to decrease laboratory errors associated with clerical mistakes
Barcode systems
The most important venipuncture step is
patient identification
Venipuncture step 1
eceive, Review, and Accession Test Request
venipuncture Step 2
Approach, Greet, and Identify the Patient
The behavior of a healthcare provider toward
or as perceived by a patient
bedside manner
It is the process of verifying a patient’s identity; it is the most crucial step in specimen
collection. It should not be rushed, or any part skipped to save time.
Patient identification
venipuncture Step 3
Explain the Procedure and Obtain Consent
Step 4:
Verify Collection Requirements, and Identify Sensitivities and Potential
Problems
Step 5:
Sanitize Hands and Put on Gloves
Step 6:
Position Patient, Apply Tourniquet, and Ask the
Patient to Make a Fist
first pumping most notably affects
level of potassium and ionized calcium
Step 7:
Select a Vein, Release the Tourniquet,
and Ask the Patient to Open the Fist
Step 8
Clean and Air-Dry the Site
a number such as a medical record number or other set of characters that is unique to the patient. This type of identifier helps eliminate mistakes caused by confusing patients with the same or similar
names or even the same name and date of birth.
