CMA Medical Assistant Practice Test: 200 Questions — Every Answer Explained

By US Testing Center Editorial Team, founded by Guinness World Records Puzzle Master Timothy E. Parker · April 18, 2026

The Bureau of Labor Statistics projects 14% job growth for medical assistants through 2032, significantly faster than the national average. That represents approximately 119,000 new positions. CMA certification from the AAMA is the most widely recognized medical assistant credential, with certified MAs earning 10-15% more than non-certified peers according to AAMA salary data.

Review courses from Mometrix cost $80 to $150. NHA study programs charge $200 to $400. Our CMA medical assistant practice test delivers 200 questions across all exam content areas with every answer explained for $79 one-time.

To be clear: this is an authentic practice test built using the ALA Mirror Method to replicate the CMA (AAMA) exam's structure, content distribution, and difficulty curve. Every question is 100% original, written by Guinness World Records Puzzle Master Timothy E. Parker.

What Is the CMA Exam?

The CMA (AAMA) exam consists of 200 multiple-choice questions covering the clinical, administrative, and general knowledge domains required for certified medical assistant practice. The exam is 160 minutes long.

The passing score is 430 on a scale of 200 to 800. The exam fee is $250 for AAMA members and $300 for non-members. Candidates must have completed a CAAHEP- or ABHES-accredited medical assisting program.

How the ALA Mirror Method Works

Sample Questions with Full Explanations

Question 1 · Clinical Knowledge · Easy

A medical assistant is taking a patient's blood pressure. The first sound heard through the stethoscope represents which of the following?

A) Diastolic pressure
B) Systolic pressure
C) Pulse pressure
D) Mean arterial pressure
Correct Answer: B — Explanation

The first Korotkoff sound heard when deflating the blood pressure cuff represents the systolic pressure, which is the pressure exerted when the heart contracts (systole). Diastolic pressure (A) is recorded when the sounds disappear (fifth Korotkoff sound). Pulse pressure (C) is the difference between systolic and diastolic readings, not an auscultated sound. Mean arterial pressure (D) is a calculated value, not a directly measured sound.

Question 2 · Administrative · Medium

A patient presents with a diagnosis of acute bronchitis. The medical assistant needs to assign the correct ICD-10-CM code. Which section of the ICD-10 manual should be consulted FIRST?

A) The Tabular List (Volume 1)
B) The Alphabetic Index (Volume 2)
C) The Procedure Classification (Volume 3)
D) The External Causes Index
Correct Answer: B — Explanation

The correct coding procedure is to consult the Alphabetic Index first to locate the condition and identify potential codes, then verify the code in the Tabular List. Starting with the Tabular List (A) without first consulting the index risks missing cross-references and inclusion/exclusion notes. Volume 3 (C) covers procedures, not diagnoses. The External Causes Index (D) codes for how injuries occurred, not disease diagnoses.

Question 3 · Pharmacology · Hard

A physician orders 500 mg of amoxicillin for a pediatric patient. The pharmacy supplies amoxicillin 250 mg/5 mL suspension. How many milliliters should the medical assistant administer?

A) 5 mL
B) 7.5 mL
C) 10 mL
D) 2.5 mL
Correct Answer: C — Explanation

Using the dosage calculation formula: Desired dose / Available dose x Volume = 500 mg / 250 mg x 5 mL = 2 x 5 mL = 10 mL. Option A (5 mL) delivers only 250 mg, half the ordered dose. Option B (7.5 mL) delivers 375 mg, which is incorrect. Option D (2.5 mL) delivers only 125 mg. Accurate dosage calculation is critical for patient safety, particularly in pediatric populations where weight-based dosing applies.
