How to Pass the CMA Medical Assistant Exam: 2026 Complete Guide
The CMA exam from AAMA tests General, Administrative, and Clinical competencies. This guide covers the exam blueprint, top-tested clinical procedures, pharmacology, and medical law topics with a 5-week study plan.
TL;DR
The CMA (AAMA) has 200 questions in 4 hours. Domains: General (40%), Administrative (20%), Clinical (40%). Passing score is 430 on a 200-430 scale. You must be a graduate of a CAAHEP or ABHES-accredited program. Focus on clinical procedures, infection control, pharmacology, and HIPAA — these dominate the exam.
Clinical Domain (40%): Highest Yield
Vital signs: normal ranges for blood pressure (<120/80 mmHg normal), pulse (60-100 bpm), respirations (12-20 breaths/min), temperature (98.6°F/37°C oral). Venipuncture: order of draw (blood culture, light blue, red, gold, green, lavender, grey). EKG: know the 12-lead placement, normal sinus rhythm characteristics, and identify common artefacts (somatic tremor, AC interference, wandering baseline). Urinalysis: normal vs. abnormal values for pH, protein, glucose, ketones, nitrites, leukocytes.
Infection Control
Chain of infection: infectious agent → reservoir → portal of exit → mode of transmission → portal of entry → susceptible host. Break the chain at every opportunity. Standard precautions apply to all patients. Transmission-based precautions: contact (MRSA, C. diff), droplet (influenza, meningitis), airborne (TB, measles, chickenpox) — requires N95 respirator. Medical asepsis (clean technique) vs. surgical asepsis (sterile technique) distinction appears frequently.
Pharmacology and Six Rights
Six rights of medication administration: right patient, right drug, right dose, right route, right time, right documentation. Routes by absorption speed: IV > IM > SC > ID > PO > SL. Know: DEA schedules (I-V), pregnancy categories (A, B, C, D, X), and the most common drug classes (analgesics, antibiotics, antihypertensives, antidiabetics). HIPAA applies to all prescription information — never discuss patient medications with unauthorised parties.
Medical Law and HIPAA
HIPAA PHI: any information that identifies a patient and relates to health status, healthcare provision, or payment. Minimum necessary standard: share only the PHI needed. Permitted disclosures without consent: public health reporting, law enforcement (with proper legal process), treatment, payment, operations. Informed consent elements: description of procedure, risks, benefits, alternatives, right to refuse. Mandatory reporting: suspected abuse (child, elder, domestic), communicable diseases, certain injuries (gunshot wounds, dog bites — varies by state).
