According to the Joint Commission, which of the following should a phlebotomist use as a unique identifier when establishing correct inpatient identification?
Patient's room number
Patient's bed label
Patient's inpatient chart
Patient's verbal confirmation
The Correct Answer is C
Choice A Reason:
A patient's room number is not considered a unique identifier by the Joint Commission standards. Room numbers can change if patients are moved, and they do not reliably identify an individual.
Choice B Reason:
A patient's bed label is also not a unique identifier. Bed labels can be switched, and similar to room numbers, they are not specific to the individual patient.
Choice C Reason:
A patient's inpatient chart typically contains multiple unique identifiers, such as the patient's name, an assigned identification number, date of birth, or other person-specific identifiers. These are considered acceptable by the Joint Commission for verifying patient identity, ensuring that the service or treatment is intended for that individual.
Choice D Reason:
Patient's verbal confirmation alone is not sufficient for establishing correct inpatient identification. While it can be used as one method of identification, it should be supplemented with another identifier to meet the Joint Commission's requirement of using at least two patient identifiers.

Correct Answer is D
Explanation
Choice A Reason:
A red-top tube is used for serum determinations in chemistry and should be allowed to clot completely, typically for 30 minutes, before centrifugation. Shipping after only 15 minutes may result in incomplete clotting and potentially inaccurate test results.
Choice B Reason:
Serum should not be separated from a lavender-top tube, as this type of tube contains EDTA and is used for whole blood tests, not serum. This indicates a misunderstanding of the tube's purpose and could lead to compromised test results.
Choice C Reason:
A tiger-top tube, also known as a serum separator tube, is used for various chemistry tests. However, bilirubin is light-sensitive, and specimens for bilirubin testing should be protected from light, not shipped in a clear bag. This could lead to degradation of the bilirubin and inaccurate results.
Choice D Reason:
A green-top tube contains heparin and is used for plasma determinations. Ammonia testing requires the plasma to be placed on ice immediately after collection to inhibit the continued production of ammonia from red blood cells. Therefore, shipping in an icy water mixture is the correct procedure to ensure accurate ammonia levels.
In conclusion, the proper preparation and transport of blood specimens are crucial for the accuracy of laboratory tests. The green-top tube for ammonia testing, shipped in an icy water mixture, is the only option that follows the correct protocol for specimen handling and transport.
Correct Answer is A
Explanation
Choice A reason:
Occult blood detection is not a process that occurs naturally after a venipuncture to control bleeding. It is a laboratory test used to detect blood in the stool that is not visible to the naked eye. This test is unrelated to the venipuncture process.
Choice B reason:
The term "Phlebotomists" refers to healthcare professionals who perform venipuncture. It is not a process but a profession. Therefore, it does not fit the context of the question regarding the control of bleeding after venipuncture.
Choice C reason:
Hematopoiesis is the process of creating new blood cells in the body and occurs in the bone marrow. While it is an ongoing process essential for replenishing the body's blood supply, it is not directly related to controlling bleeding after a venipuncture.
Choice D reason:
Hemoconcentration is a condition where the blood concentration of cells and solids is higher than normal, usually due to a loss of plasma. This can occur during venipuncture if the tourniquet is left on for too long, but it is not a process used to control bleeding.
