Which of the following information should the physician's office provide to a phlebotomist for laboratory specimen collection?

Choice A Reason:
Withdrawing the needle completely would be an incorrect action because it would end the procedure prematurely and require a new venipuncture, causing unnecessary discomfort to the patient. It should only be done if the venipuncture has been completed or if there is a need to stop due to a complication.

Choice B Reason:
Rotating the bevel of the needle could potentially reposition the needle for better blood flow if it has become occluded or is not properly aligned with the vein. However, this action should be done with caution to avoid causing injury to the vein or discomfort to the patient.

Choice C Reason:
Increasing tourniquet pressure is not advisable once blood flow has been established, as it could cause damage to the vein or hemolysis of the blood sample. The tourniquet should be released once the blood starts flowing into the first tube to avoid these issues.

Choice D Reason:
Activating a new evacuated tube is the correct action to take when blood flow stops upon attaching a second tube. This could indicate a problem with the vacuum in the tube rather than with the needle or the venipuncture site. Trying a new tube can resolve the issue without needing to adjust the needle or the patient's position.

Choice A reason:
The laboratory accession number is a unique identifier assigned to a patient's specimen once it is received by the laboratory. While it is an important piece of information, it is not provided by the physician's office to the phlebotomist for specimen collection. Instead, it is generated by the laboratory after the specimen is collected and submitted for analysis.

Choice B reason:
The Physician's NPI (National Provider Identifier) number is a unique identification number for covered health care providers in the United States. While it is used for billing and identification purposes, it is not the information that the physician's office needs to provide to a phlebotomist for the purpose of specimen collection.

Choice C reason:
The laboratory requisition form is the correct document that should be provided by the physician's office. This form contains the patient's demographic information, the tests ordered by the physician, special instructions for specimen collection, and any other pertinent information required for proper specimen handling and testing.

Choice D reason:
The physician's encounter form typically contains details of the patient's visit, including services provided, diagnoses, and billing information. It is not specifically used for laboratory specimen collection and therefore is not the information that should be provided to a phlebotomist for this purpose.
