CLA Test 2 Study Guide – 350 Medical Terminology Questions and Verified Answers on Musculoskeletal, Blood, Immune, and Cardiovascular Systems (CLA) – Clinical Laboratory Assistant – 2026

This document contains approximately 350 exam questions with verified answers designed to help students prepare for CLA Test 2 in Clinical Laboratory Assistant and allied health programs. The study material provides an extensive review of medical terminology, anatomy, diseases, diagnostic procedures, and treatments related to the musculoskeletal system, hematology, immune system, lymphatic system, and cardiovascular system. Early sections of the document introduce key medical word roots and terminology used in musculoskeletal anatomy such as oste/o (bone), spondyl/o (vertebra), tars/o (tarsal bones), and myel/o (bone marrow). The material also explains structural components such as ligaments, tendons, joints, and bones, and describes common conditions including arthritis, osteoporosis, muscular dystrophy, fractures, spinal deformities such as kyphosis and scoliosis, and injuries such as sprains and tendonitis. The document further explores diagnostic and surgical procedures related to orthopedic medicine, including arthroscopy, arthroplasty, laminectomy, diskectomy, joint repair procedures, fracture reduction techniques, and muscle or tendon repair surgeries. These sections also introduce orthopedic treatments such as prosthetics, orthotics, and therapeutic approaches like the RICE method (rest, ice, compression, elevation) commonly used for musculoskeletal injuries. These topics help students understand how skeletal and muscular disorders are diagnosed and treated in medical practice. Additional sections focus on blood, lymphatic, and immune system terminology, including definitions related to blood components, immune responses, and hematologic conditions. Topics include blood cell abnormalities such as anisocytosis, macrocytosis, and polycythemia, as well as diseases such as anemia, leukemia, bacteremia, septicemia, and autoimmune disorders. The study guide also explains infectious diseases and immune responses, including conditions such as AIDS, influenza, diphtheria, measles, malaria, and tetanus. Laboratory diagnostic procedures are reviewed in detail, including complete blood count (CBC), differential white blood cell count, blood cultures, coagulation tests, immunization, and vaccination methods used in modern medicine. The final sections provide extensive coverage of cardiovascular system terminology and clinical conditions, including heart anatomy and circulation concepts involving arteries, veins, atria, ventricles, and blood vessels. Important cardiovascular diseases and symptoms discussed include arrhythmia, tachycardia, hypertension, coronary artery disease, myocardial infarction, cardiomyopathy, and heart failure. Diagnostic imaging and cardiovascular procedures such as angiography, angioplasty, echocardiography, electrocardiography (ECG/EKG), cardiac catheterization, coronary artery bypass grafting (CABG), and defibrillation are also included to help students understand modern cardiac diagnostic and treatment techniques. The content aligns with learning objectives commonly taught in clinical laboratory assistant, medical terminology, anatomy, and allied health courses, and complements widely used textbooks such as Medical Terminology for Health Professions by Ann Ehrlich and Carol L. Schroeder, which provide foundational knowledge in medical vocabulary, anatomy, and disease processes. Because the guide covers multiple body systems and clinical concepts in a question-and-answer format, it serves as a comprehensive revision resource for healthcare students preparing for exams, certification tests, and laboratory coursework.
