Surgical Specimen Handling & Documentation Flashcards

When a surgical specimen is handed off the sterile field, what is the FIRST step the circulating nurse should take?

Answer: Label the specimen container with patient information before placing the specimen inside

The container must be labeled with patient identifying information BEFORE the specimen is placed inside. Labeling after placement risks specimen mix-up. Required information typically includes patient name, MRN, date, surgeon, specimen source/site, and laterality when applicable.

An intraoperative frozen section is ordered during a mastectomy. What is the PRIMARY purpose of this test?

Answer: To provide a rapid intraoperative pathologic diagnosis that guides the ongoing procedure

A frozen section allows the pathologist to examine tissue within approximately 15–20 minutes while the patient remains on the table. The surgeon uses these results to make real-time decisions — for example, whether surgical margins are clear or whether a lymph node contains malignant cells.

Which fixative is most commonly used to preserve surgical tissue specimens for routine permanent pathology?

Answer: 10% neutral buffered formalin

10% neutral buffered formalin (NBF) is the universal standard fixative for routine surgical pathology. It preserves tissue architecture and cellular morphology for histologic examination. Normal saline keeps tissue temporarily moist but does not fix it. Glutaraldehyde is reserved for electron microscopy.

When should a surgical specimen NOT be placed in formalin?

Answer: When a frozen section or microbiologic culture has been requested

Formalin kills microorganisms and alters tissue architecture in ways that prevent frozen section processing and destroy viable cells needed for culture. Specimens sent for frozen section analysis or microbiology cultures (bacterial, fungal, AFB) must be sent fresh — without fixative — to the appropriate lab.

Which of the following pieces of information is REQUIRED on a surgical specimen label?

Answer: Patient name, medical record number, specimen source/site, and surgeon's name

Specimen labels must include patient identifiers (name and MRN), the anatomic source and site of the specimen (with laterality when applicable), and the operating surgeon's name. This is the minimum required to ensure correct pathology reporting and prevent misidentification errors.

During a sentinel lymph node biopsy, the surgeon uses a radioactive tracer and/or blue dye. Why must the scrub tech understand the specimen handling protocol for this procedure?

Answer: The radioactive node must be sent fresh (without formalin) to nuclear medicine, then to pathology for frozen section

Sentinel lymph node specimens follow a special chain of custody: the radioactive node is identified with a Geiger counter intraoperatively, then sent fresh (never in formalin) to nuclear medicine for counting and subsequently to pathology for frozen section analysis. Adding formalin would destroy the radioactive signal and prevent frozen section processing.
