Which of the following information should the physician's office provide to a phlebotomist for laboratory specimen collection?
Laboratory accession number
Physician's NPI number
Laboratory requisition form
Physician's encounter form
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A reason:
A 23-gauge needle is commonly used for venipuncture with a winged infusion set and a small volume syringe like a 5 mL syringe. This size provides a balance between patient comfort and the ease of drawing blood without causing hemolysis or excessive damage to blood cells. It is large enough to allow blood to flow easily into the syringe but small enough to minimize discomfort and the risk of bruising.
Choice B reason:
An 18-gauge needle is quite large and is typically used for situations requiring rapid administration of fluids or for blood donation where larger volumes are collected quickly. It is not ideal for a standard venipuncture, especially with a small syringe, as it can cause more pain and increase the risk of bruising.
Choice C reason:
A 25-gauge needle is on the smaller side and may be used for patients with very fragile veins or for pediatric patients. However, it may not be the best choice for a 5 mL syringe as it could make the blood draw process slower and more difficult, potentially leading to clotting in the needle or syringe.
Choice D reason:
A 27-gauge needle is very small and is typically used for subcutaneous injections, such as insulin injections, rather than for venipuncture. It would be too small for an efficient blood draw with a 5 mL syringe, as it would likely cause the blood to hemolyze or clot before the draw is completed.
Correct Answer is A
Explanation
Choice A reason:
When performing a capillary blood collection, such as a fingerstick, the lancet should be positioned perpendicular to the fingerprint grooves. This orientation helps to ensure that the incision is made across the ridges of the fingerprint, which can facilitate a better blood flow and make it easier to collect an adequate sample without needing to squeeze the finger excessively, which could hemolyze the sample.
Choice B reason:
Positioning the lancet parallel to the nail bed is not recommended because it can result in a cut that runs along the length of the fingerprint grooves, which may not bleed as freely and could also be more painful for the patient.
Choice C reason:
Using the lancet along the lateral portion of the first digit is not part of the standard aseptic technique protocol for capillary blood collection. The first digit, or thumb, has a pulse and should generally be avoided because it can be more sensitive and is more prone to bruising.
Choice D reason:
The medial portion of the fifth digit, or the little finger, is also not a recommended site for capillary blood collection with a lancet. The little finger is typically smaller and may not provide an adequate site for blood collection, and similar to the thumb, it can be more sensitive and prone to injury.
