CMA (AAMA) Certification Examination common mistakes

CMA (AAMA) · Understand the traps and how to avoid them.

Mistake 1

Studying medical terminology as term-to-definition flashcards only, so the candidate can recite that '-ectomy' means removal but freezes when a stem describes a procedure in words and asks them to pick or build the term (e.g., naming the term for surgical creation of an opening between two ducts).

Flashcard apps train recognition memory (see the word, recall the definition) but exam items require productive, analytic use - splitting an unfamiliar word into prefix/root/suffix and synthesizing a definition or a term from a description.

What to do instead

Do a daily drill of 10 unfamiliar words: underline prefix, root, suffix, write the literal meaning, then write a plain-English definition. Add reverse drills where you are given only the definition and must construct the term from word parts.

Mistake 2

Answering scope-of-practice and legal/ethical scenario items (delegation, patient teaching, releasing information, accepting a verbal order) with the clinically best-sounding action instead of the legally permissible one.

Candidates trust clinical instinct and a vague sense of 'common sense,' but have never built an explicit list of what the medical assistant may and may not do, which varies by state and by provider delegation.

What to do instead

Build a two-column 'MA may / MA may not' sheet from your program's scope content (e.g., may perform patient education on an established plan but may not diagnose or independently advise; may not interpret results). On every legal/ethical item, screen options for scope and legality before judging quality of care.

Mistake 3

On 'first/next/priority/except' items, picking the most complete, most courteous, or most thorough option rather than the one that matches the task word in the stem.

Under time pressure candidates skim the stem, read the options, and select whichever sounds best overall - the exam deliberately writes plausible later steps and plausible 'more thorough' answers as distractors.

What to do instead

Physically mark the task word before reading options. On priority items apply a fixed hierarchy (life threat/ABCs first, then scope and policy, then comfort and courtesy). On 'except' items restate the stem in your own words as 'three of these are true.'

Mistake 4

Choosing a scheduling or recall answer that sounds polite or convenient without checking it against the constraints stated in the stem - new versus established patient, urgent versus routine, same provider versus any provider, required visit length or equipment.

Scheduling is learned as a list of appointment types rather than as constraint matching, so candidates eliminate on tone instead of on the stated facts.

What to do instead

Underline every constraint in the stem first, then eliminate any option that violates even one of them. Practice by writing three-constraint scheduling items for yourself and rejecting options one constraint at a time.

Mistake 5

Getting the sequence wrong on financial and insurance tasks - posting payments before verifying eligibility, appealing a denial without first checking the remittance advice, or ordering CMS-1500 completion steps incorrectly - and mixing up copay, coinsurance, and deductible in scenario items.

These terms are memorized as definitions rather than as a workflow, so the candidate knows what each word means but not where it sits in the revenue cycle.

What to do instead

Write each process as a numbered flow (eligibility/benefits verification, coding, claim submission, remittance posting, denial review, appeal) and self-quiz on 'what happens immediately before and after this step.' Draw the copay/coinsurance/deductible distinction on one page with a worked dollar example.

Mistake 6

On record-release items, choosing options like handing records to a caller who identifies as a family member, an attorney, or an insurance representative, and being unsure which documents belong in the medical record versus kept separately.

Candidates correctly learn that the patient owns the information and conclude the record can be shared, conflating ownership with authorization; they also have no mental list of separately maintained documents.

What to do instead

Drill a release checklist: valid written authorization naming specific records and dates, identity verification of the requester, correct recipient and method, and state-specific rules for sensitive categories. Separately memorize which items are not part of the chart (incident reports, some correspondence) and are stored per facility policy.

Mistake 7

Anchoring on a single abnormal vital sign and choosing a low-urgency action - for example, selecting 'recheck the blood pressure in 30 minutes' for a patient who is also diaphoretic, pale, and confused.

Vital signs are studied as isolated normal ranges, so the candidate evaluates the number rather than the patient; exam items are written specifically to test whether the whole picture changes the urgency.

What to do instead

For every abnormal value, ask 'what else in this stem changes the urgency?' Memorize a short list of findings that mandate immediate provider notification or emergency response, and rehearse combining findings rather than reading them one at a time.

Mistake 8

Dosage-calculation errors caused by unit mismatch or premature rounding - setting up a proportion with mg in one position and mcg in another, converting pounds to kilograms after calculating, or rounding mid-equation so the final answer is off by a factor of 1,000.

Candidates do the arithmetic mentally or in fragments, and dimensional analysis is not practiced under time pressure, so the conversion step gets dropped.

What to do instead

Write the full equation every time with units written next to every number so mismatched units are visible and cancel. Convert weight first, round only at the end, and finish by sanity-checking: 'is this dose plausible for this route, age, and weight?'

Mistake 9

Performing procedure steps out of order in scenario items - re-palpating a site after cleansing, filling blood tubes in the wrong order, not allowing antiseptic to dry, or reaching across a sterile field after it is established.

Procedures are learned by watching and doing, which builds smooth motor sequences but not explicit recall of boundary steps; exam items target exactly those 'never do this after that' points.

What to do instead

Rewrite each procedure as a numbered checklist from memory, then check it. Star the irreversible boundary steps (order of draw, dry time, no re-palpation, sterile field boundaries, sharps disposal timing) and drill only those until automatic.

Mistake 10

Missing infection-control specifics on items where the general principle is known but the detail is fuzzy - selecting 'wear gloves' as a complete answer, choosing sterilization for an item that requires only disinfection, or scrambling the order of removing PPE.

Broad principles feel familiar enough to stop study, so the candidate never locks in doffing order, contact times, or the critical/semicritical/noncritical classification that drives the correct method.

What to do instead

Memorize PPE doffing order and disinfectant contact times verbatim, and build a three-row table (critical, semicritical, noncritical) with the correct processing method for each. On every infection-control item, ask which category the item belongs to before choosing a method.
