CLA Exam 1 Study Guide – 150 Medical Terminology Questions and Verified Answers on Integumentary System, Medical Prefixes, and Skin Disorders (CLA) – Clinical Laboratory Assistant – 2026

This document contains approximately 150 exam questions with verified answers designed to help students prepare for CLA Exam 1 in Clinical Laboratory Assistant and allied health programs. The material provides a comprehensive review of medical terminology, including prefixes, suffixes, and combining forms used throughout anatomy, physiology, and clinical practice. Early sections of the document define common medical word roots such as cran/o (skull), cephal/o (head), thorac/o (chest), and pelv/o (pelvis), along with important prefixes like tachy- (fast), dys- (abnormal or painful), and intra- (within). These components help students understand how medical terms are constructed and interpreted in clinical documentation and healthcare communication. The study guide also covers foundational anatomy terminology and body cavity organization, including the dorsal cavity (cranial and spinal cavities), the ventral cavity, and subdivisions such as the thoracic, abdominal, and pelvic cavities. Additional sections review anatomical structures and functions of the integumentary system, including the epidermis, dermis, and hypodermis layers of the skin, as well as the accessory structures embedded within the skin such as hair follicles, nails, sweat glands, and sebaceous glands. The document explains the physiological roles of the integumentary system, including protection from dehydration and infection, regulation of body temperature, and sensory perception through specialized receptors. Further content focuses on common dermatological conditions and clinical terminology used to describe skin injuries, infections, and abnormalities. These include terms such as abrasion, abscess, cyst, edema, erythema, contusion, cyanosis, jaundice, papule, pustule, vesicle, and ulcer. The document also introduces several medical conditions affecting the skin and connective tissues, including psoriasis, melanoma, cellulitis, impetigo, alopecia, scabies, and systemic lupus erythematosus. Surgical and diagnostic terminology is also included, such as biopsy, dermabrasion, dermatoplasty, rhytidectomy, and debridement procedures used in medical treatment and wound management. The material aligns with learning objectives commonly taught in introductory medical terminology, anatomy, and clinical laboratory assistant courses, and supports content typically presented in textbooks such as Medical Terminology for Health Professions by Ann Ehrlich and Carol L. Schroeder. The question-and-answer format allows students to efficiently review large volumes of terminology and clinical definitions that are frequently tested in healthcare certification exams and allied health coursework.
