Step-by-Step Guide to Labeling Exercise 8.2

Labeling Exercise 8.2, like similar exercises, is designed to test your understanding of proper labeling procedures. Here’s a detailed guide to approaching such exercises:

1. Review the Scenario:

• Carefully read the entire scenario. Pay close attention to the patient's name, DOB, MRN, the tests requested, the date and time of collection, and any other relevant information.
• Identify any potential "red flags" or unusual circumstances, such as a patient with a similar name or special handling instructions.

2. Prepare the Labels:

• Before collecting the specimen, prepare all necessary labels. This includes labels for the blood collection tubes and the requisition form.
• Use a label printer if available, as it provides a clear and legible label. If handwriting, use a ballpoint pen and write legibly in block letters.

3. Patient Identification - The Critical First Step:

• Positively identify the patient. This is the most important step. Use two patient identifiers. Acceptable identifiers include:
  • Asking the patient to state their full name and date of birth.
  • Comparing the information on the patient's wristband with the requisition form.
• Never rely solely on the patient's room number or bed number for identification. Patients may be moved.
• If the patient is unable to verbally confirm their identity (e.g., unconscious or confused), verify their identity with a nurse or other healthcare professional who knows the patient.
• If there is no wristband, follow your facility's protocol for un-identified patients. Do not proceed with the blood draw until the patient is properly identified.

4. Verify Information:

• Compare the information provided by the patient (or their representative) with the information on the requisition form. Ensure all information matches exactly.
• If there are any discrepancies, resolve them before proceeding. Contact the ordering physician or the nursing staff to clarify the information. Do not guess or assume anything.

5. Label the Blood Collection Tubes Immediately After Collection:

• Label the tubes at the patient's bedside immediately after drawing the blood. Never pre-label tubes.
• Ensure the label is securely attached to the tube and does not cover the volume markings.
• Write the date, time, and your initials on the label.

6. Label the Requisition Form:

• Complete the requisition form with all the necessary information, including the date and time of collection, specimen source, and any special instructions.
• Sign or initial the requisition form to indicate that you have collected the specimen.

7. Final Verification:

• Before leaving the patient's bedside, double-check that all labels are accurate and legible and that all information on the requisition form is complete.
• Compare the information on the tubes to the information on the requisition one last time.

8. Documentation:

• Document any issues or discrepancies that occurred during the collection process in the patient's chart or in the laboratory information system.

Common Labeling Errors and How to Avoid Them

Even experienced healthcare professionals can make mistakes. Here are some common labeling errors and strategies to prevent them:

• Misidentification of the Patient:
  • Prevention: Always use two patient identifiers. Never rely on room number or bed number. Verbally confirm the patient's identity whenever possible.
• Incorrect Date or Time of Collection:
  • Prevention: Double-check the date and time before writing them on the label. Use a standardized time format (e.g., military time).
• Illegible Handwriting:
  • Prevention: Use a label printer whenever possible. If handwriting, use a ballpoint pen and write legibly in block letters.
• Missing Information:
  • Prevention: Use a checklist to ensure that all required information is included on the label and requisition form.
• Pre-Labeling Tubes:
  • Prevention: Never pre-label tubes. Always label tubes at the patient's bedside immediately after collection.
