Phlebotomy Technician Practice Exam (NCPT/CPT)

Which of the following should be used to label an armband and collection tubes?

1. Data on the patients

2. Patient's last name and date of birth

3. Barcode system

4. Patient's verbal confirmation

The correct answer is: Data on the patients

When labeling an armband and collection tubes, it is important to include key identifying information to ensure accuracy and prevent mix-ups. Option A is the best choice because it includes specific data on the patient, such as their name, date of birth, and potentially other important identifiers. Option B only includes the patient's last name and date of birth, which can be more easily duplicated or confused with other patients. Option C, a barcode system, may be helpful in some cases, but it still relies on accurate patient information to be effective. Option D, relying on patient's verbal confirmation, may be unreliable and can lead to mistakes. Therefore, option A is the most comprehensive and reliable choice.
