NBSTSA CST Practice Exam A 2026/2027 | 175 Questions & Answers | Sterile Technique, Surgical Procedures, Anatomy & Instruments

This NBSTSA CST Practice Exam A 2026/2027 is a comprehensive 71-page Certified Surgical Technologist (CST) exam-preparation resource containing 175 multiple-choice questions with answers. It provides broad practice across core surgical technology competencies, including sterile technique, aseptic practice, surgical anatomy and physiology, instrumentation, operative procedures, patient positioning, wound healing, sterilization, infection prevention, pharmacology, anesthesia, surgical safety, and perioperative patient care. The question-and-answer format closely focuses on the applied knowledge surgical technology students need when preparing for certification-style examinations. The practice material covers an extensive range of surgical specialties and procedures, including general surgery, cholecystectomy, appendectomy, nephrectomy, TURP, hysterectomy, dilation and curettage, craniotomy, laminectomy, carotid endarterectomy, arthroplasty, ACL repair, tympanoplasty, ophthalmic surgery, vascular procedures, mastectomy, C-section, hernia repair and laparoscopic procedures. Students are tested on the correct use and identification of instruments such as Randall forceps, Gelpi and Balfour retractors, Mixter and Kocher clamps, Kerrison and pituitary rongeurs, resectoscopes, Javid shunts, Ellik evacuators, Kirschner wires, Mayfield clamps and surgical staplers. A strong emphasis is placed on aseptic and sterile technique, including sterile-field management, surgical draping, gowning and gloving, surgical hand scrubbing, instrument and sponge counts, sharps disposal, contaminated instruments, steam sterilization, biological monitoring, instrument processing and reducing bioburden. Questions also assess infection prevention, surgical-site infection risks, wound classification and healing, specimen handling, frozen sections, operating-room attire and safe management of sterile supplies. The resource additionally integrates anatomy, physiology, microbiology and pharmacology into realistic perioperative scenarios. Covered concepts include cranial nerves, abdominal tissue layers, kidney anatomy, gastrointestinal anatomy, respiratory and cardiovascular physiology, shock, hemoglobin, hepatitis B, wound inflammation and surgical complications. Pharmacology questions address medications and agents such as atropine, mannitol, propofol, heparin, protamine sulfate, bupivacaine, lidocaine, Demerol, silver sulfadiazine and succinylcholine, including recognition of malignant hyperthermia and medication calculations. Patient safety and professional responsibilities are another major component. The exam reviews informed consent, patient confidentiality, blood-transfusion reactions and refusal, scope of practice, delegation, patient transfer, specimen management, legal concepts such as battery and res ipsa loquitur, positioning precautions, tourniquet safety and postoperative care. This combination of clinical knowledge, technical skills, safety principles and scenario-based decision-making makes the document useful for comprehensive CST certification review. Relevant Students: This document is most relevant to Certified Surgical Technologist (CST) candidates, NBSTSA exam candidates, surgical technology students, Surgical Technologist program students, operating room technology students, perioperative technology students, associate-degree surgical technology students, recent surgical technology graduates, and students preparing for CST certification or comprehensive surgical technology examinations. The document is associated with NBSTSA certification preparation rather than a specific university, and no university is identified in the uploaded material. Referenced Academic/Professional Framework: The content aligns broadly with the knowledge areas tested in Certified Surgical Technologist (CST) preparation, including perioperative care, ancillary duties, basic science, surgical procedures, sterile technique, instrumentation and patient safety. The uploaded document itself does not provide a complete bibliographic citation for a textbook or peer-reviewed journal, so an academic book or journal citation should not be fabricated and attributed to it.
