ASCP Phlebotomy Practice Exam 2026/2027 | 100+ Questions & Answers | Order of Draw, Blood Collection, Tubes, Hemostasis, ABG & Specimen Handling

This ASCP Phlebotomy Practice Exam 2026/2027 provides 100+ exam questions and answers across 18 pages, covering essential phlebotomy procedures, blood collection principles, specimen handling and foundational clinical laboratory knowledge. The material reviews blood composition, plasma and serum, red and white blood cells, hematocrit, hemolysis, hematoma, medical asepsis, blood volume and common laboratory terminology. It also covers blood collection tubes and additives, including sodium fluoride, oxalate, EDTA, heparin, SPS, thrombin and tubes used for electrolyte panels, trace-metal analysis, blood alcohol testing and STAT serum testing. A major section concentrates on practical specimen-collection procedures and patient safety. Students review order of draw, venipuncture alternatives, capillary puncture sites, therapeutic phlebotomy, blood donation, bloodborne-pathogen precautions, medical asepsis, specimen contamination and patient positioning. The document also examines the phases of hemostasis—vascular, platelet, coagulation and fibrinolysis—and includes questions about activated clotting time, PT, PTT and heparin monitoring. These topics make the resource useful for reinforcing both procedural knowledge and the laboratory principles underlying safe blood collection. The practice material extends into arterial blood gas collection and arterial puncture, including PO2, oxygen saturation, acid-base assessment, the Allen test, collateral circulation, radial and ulnar arteries, infant arterial collection sites, local anesthetic administration and vasovagal responses. Additional questions address glucose testing, electrolytes, renal function, urinalysis, trough drug levels, blood alcohol specimens, trace elements, BNP testing, PPD/TB testing and other diagnostic laboratory procedures commonly encountered in phlebotomy and clinical laboratory environments. The document also incorporates supporting anatomy, physiology and medical terminology relevant to phlebotomy practice. Topics include the nervous, endocrine, respiratory and gastrointestinal systems, along with conditions such as diabetes mellitus, Cushing syndrome, asthma, hypoxia, meningitis, Parkinson disease, GERD, anemia and congestive heart failure. Safety and professional-practice concepts include OSHA requirements, Safety Data Sheets, chemical hazards, fire safety and intentional torts, giving students broader preparation for questions involving workplace safety and professional responsibilities.
