ASCP BOC Pathologists' Assistant (PA) Examination Practice Test
Pathologists’ assistant work connects surgical pathology and autopsy practice with accurate specimen handling and gross examination. This practice set samples decisions involving specimen identification, biosafety, orientation, margin assessment, lymph node evaluation, and tissue preservation. These tasks support reliable gross descriptions and help ensure representative tissue is available for histologic examination.
Exam overview
About the ASCP BOC Pathologists' Assistant (PA) Examination Exam
Questions focus on applying sound judgment at the grossing bench, where specimen integrity and traceable documentation matter. Scenarios address discrepancies between a specimen label and requisition, missing anatomic-site information, and handling tissue submitted under designated biosafety procedures. Gross examination tasks include documenting lesion location, evaluating possible margins, assessing a spleen for traumatic injury, and examining a sentinel lymph node while retaining tissue for permanent sections. Other prompts concern bowel resections with stapled ends and processing small biopsies without losing tissue. The underlying skills include recognizing when clarification is needed before proceeding, selecting an approach that preserves diagnostic material, and recording gross findings in a way that supports pathologist review and correlation with microscopic sections.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A fresh surgical specimen arrives in formalin with a label that does not match the requisition. What should the pathology assistant do first?
Show answer
Correct answer: BA specimen identity discrepancy is a patient-safety issue. The specimen should be held while the discrepancy is resolved through the established chain of communication; staff should not independently alter identifiers or proceed as though identity were confirmed.
A specimen is submitted for a suspected infectious disease, and the laboratory has a designated biosafety procedure. What is the appropriate approach for the pathology assistant?
Show answer
Correct answer: APotentially infectious specimens should be handled according to the laboratory's risk assessment, applicable biosafety guidance, and institutional procedures. The required containment and precautions depend on the suspected hazard and planned work.
A hysterectomy specimen is received with a cervical lesion. Which approach best supports accurate gross documentation of the lesion's location?
Show answer
Correct answer: AA useful gross description documents lesion size, site, and relationship to relevant anatomic landmarks and margins. Recording these details before further dissection helps preserve spatial context for pathologic assessment.
A colectomy specimen includes a separate, unoriented fragment of tissue labeled as a possible margin. What is the most appropriate grossing approach?
Show answer
Correct answer: AA separately submitted fragment should be documented as received. Unless reliable orientation information is provided, its specific anatomic identity should not be inferred or assigned. The fragment should be submitted for examination according to the case protocol.
A sentinel lymph node is submitted for intraoperative evaluation. Which grossing practice best supports examination of the entire node while preserving tissue for permanent sections?
Show answer
Correct answer: ABisecting a node through its longest dimension exposes a broad cut surface for evaluation and can allow frozen-section sampling while retaining material for subsequent permanent sections. The exact protocol depends on laboratory policy and the diagnostic request.
A bowel resection specimen includes a stapled end. What is the appropriate general approach before evaluating the bowel wall near that end?
Show answer
Correct answer: AStapled ends may represent a resection margin and should be recognized and documented. The staple line can be removed or the end opened according to local procedure so the relevant margin and adjacent tissue can be examined and sampled appropriately.
A fresh spleen is received for gross examination. Which feature is most useful to assess and document when evaluating for possible traumatic injury?
Show answer
Correct answer: ACapsular tears, lacerations, and parenchymal disruption are key gross findings in suspected splenic trauma. Their location and extent should be described, with attention to any associated hematoma or rupture.
How to use this practice test
Access is free. Each session presents up to 20 random questions from the 50-question practice bank, with results shown after the session. Use the scenarios to check your reasoning on specimen acceptance, gross examination, documentation, and tissue preservation; review missed items by identifying the specimen-handling decision involved.
Preparation tips
- Practice a consistent response to identification discrepancies: stop processing, preserve the specimen, and seek clarification through the laboratory’s established procedure.
- For grossing scenarios, record lesion location and orientation using clear anatomic landmarks, and distinguish an unoriented possible margin from a confirmed margin.
- Review how to examine and document lymph nodes and how to retain representative tissue for permanent sections after intraoperative evaluation.
- Compare handling needs for fresh, formalin-fixed, infectious-risk, and small biopsy specimens, including steps that reduce tissue loss during processing.
