§01
What this domain asks
Wide but shallow. Most items are one-line recall.
NHA's 2022 test plan puts 15 scored items here, and they come from six different places: health-care systems and roles, the federal agencies, medical word parts, basic pharmacology with dosage math, nutrition, and psychology. The good news is the depth. Items are one-line recall stems ("The suffix -megaly means:") or two-sentence office scenarios, so the work is matching a term to its meaning.
The highest-return move is word parts. A root, one prefix and one suffix decode dozens of terms you've never seen before, and the same skill pays off again in anatomy and physiology, where the 8 scored items lean on the same vocabulary. Learn the parts in the table below, then test them on the questions at the end of this page.
§02
Word parts that decode most terms
Learn the part once; it repeats across every body system.
| Word part | Kind | Meaning | Built into |
|---|---|---|---|
| cardi/o | root | heart | cardiology, cardiomegaly |
| hepat/o | root | liver | hepatitis, hepatomegaly |
| gastr/o | root | stomach | gastritis, gastroscopy |
| nephr/o, ren/o | root | kidney | nephrology, renal |
| pneum/o, pulmon/o | root | lung | pneumonia, pulmonology |
| oste/o | root | bone | osteoporosis, osteomyelitis |
| neur/o | root | nerve | neuralgia, neurology |
| hem/o | root | blood | hemorrhage, hematology |
| brady- / tachy- | prefix | slow / fast | bradycardia, tachypnea |
| hyper- / hypo- | prefix | above / below | hypertension, hypoglycemia |
| dys- | prefix | painful, difficult | dyspnea, dysuria |
| a-, an- | prefix | without | apnea, anemia |
| poly- | prefix | many | polyuria |
| -itis | suffix | inflammation | appendicitis |
| -ectomy | suffix | removal | appendectomy |
| -ostomy / -otomy | suffix | new opening / incision | colostomy, tracheotomy |
| -algia | suffix | pain | arthralgia |
| -emia | suffix | blood condition | hyperglycemia |
| -megaly | suffix | enlargement | splenomegaly |
| -pnea | suffix | breathing | orthopnea |
| -uria | suffix | urine | hematuria |
| -ology / -pathy | suffix | study of / disease | cardiology, neuropathy |
Read a term from the end: the suffix tells you what happened, the root tells you where.
§03
Health-care systems and roles
Who does what, and where the MA fits.
A handful of items check that you can place people and settings correctly. Licensing is a state's legal permission to practice; certification is a credential from a private body, which is what the CCMA is. A medical assistant is an allied health professional, working under a provider's delegation, alongside radiologic technologists and phlebotomists, while nursing is its own licensed profession.
Expect a stem that describes a patient and asks which specialist fits: the root does most of the work (endocrin/o for glands and hormones, nephr/o for kidneys, a physiatrist for rehabilitation, which is easy to misread as psychiatrist or podiatrist). Care models show up too: a patient-centered medical home coordinates care through a primary care team, holistic care treats the whole person, and telehealth moves the visit to video or phone. Read the scope question carefully; anything that sounds like diagnosing or prescribing belongs to the provider, a line drawn on the scope of practice page.
§04
Which agency does what
The CDC-versus-FDA swap is the classic negative-phrased item.
- FDA
Regulates and approves drugs, vaccines and medical devices. A vaccine is licensed by the FDA, not the CDC.
- CDC
Disease surveillance and public-health guidelines, including infection-control and immunization guidance. It doesn't license products.
- OSHA
Worker safety: the Bloodborne Pathogens Standard, sharps rules and PPE an employer must supply. Details on the infection control page.
- CMS
Runs Medicare and Medicaid.
- TJC
The Joint Commission accredits health-care organizations and keeps the "Do Not Use" list of error-prone abbreviations.
§05
Pharmacology at the CCMA level
Classes and vocabulary carry it. Skip drug-by-drug lists.
The pharmacology here is the vocabulary a medical assistant needs to give a medication safely under a provider's order. Expect items on:
- Drug schedules under the Controlled Substances Act: the schedule number tracks abuse potential and whether the drug has an accepted medical use.
- Side effect versus adverse effect: an expected, usually mild extra effect versus a harmful, unintended reaction.
- Indication versus contraindication: the reason to give a drug versus the reason not to.
- ADME: absorption, distribution, metabolism, excretion, in that order.
- Look-alike / sound-alike drug names and the abbreviations TJC tells you not to write.
Dosage math is the one part that rewards practice over reading. Set up every problem the same way, keep the units in the setup, and check that the answer is a sensible volume. The dosage calculations page walks through the setup with worked questions, and the exam's built-in calculator is the only one you may use.
§06
Nutrition and psychology
Maslow is the item you can count on.
Physiologic needs
Air, water, food, sleep. The base of Maslow's hierarchy, met before anything above it.
Safety
Physical security, a stable home, freedom from pain or threat.
Love and belonging
Family, friends, a place in a group.
Esteem
Respect, recognition, confidence.
Self-actualization
Reaching personal potential. The top, addressed last.
Psychology items also touch developmental stages, common defense mechanisms (denial, projection, regression) and the stages of grief. Nutrition items ask about diets matched to a disease and about vitamins, usually as a contrast between two groups. In both, the stem describes a patient and asks you to name what you see; the work is matching the description to the label.
§07
Terminology and pharmacology, settled
Where the vocabulary shows up, and how to learn it.
Is CCMA medical terminology tested only in this domain?
No. Terminology is one of six topic areas here, and word parts also carry anatomy, vitals and EKG stems. Bradypnea, cholecystectomy and osteomyelitis can each turn up outside this domain.
Is there pharmacology on the CCMA?
Yes, at the level of drug classes, schedules, effects, routes and dosage math. Route and injection technique are tested separately under general patient care.
Do I need to memorize medical abbreviations?
The common ones (BMI, PPE, EHR, IM, SubQ, PHI) appear in stems without being spelled out. You should also know that TJC keeps a "Do Not Use" list of abbreviations that cause dosing errors.
What is the fastest way to study terminology?
Learn word parts first. A few dozen roots, prefixes and suffixes decode most terms on the exam. Drill them with the flashcards, then check yourself on the questions below.
§08
Test the word parts and agencies
Word parts, agencies, schedules, Maslow. Each option is explained.
Answer first, then read the breakdown under every option, including the ones you ruled out. If you miss two word-part items in a row, go back to the table above before carrying on.
Oxycodone has a high potential for abuse but an accepted medical use. Under the Controlled Substances Act, it is a:
Answer & explanation
Answer: A. Schedule II drug
Schedule II drugs, such as oxycodone and fentanyl, have high abuse potential but accepted medical use, so they need a written or electronic prescription with no refills. Schedule I is tempting because of the abuse risk, but it is for drugs with no accepted medical use, such as heroin. Schedules III through V have progressively lower abuse potential.
- Correct: Schedule II covers drugs with high abuse potential that still have accepted medical use, like oxycodone, morphine and fentanyl.
- Schedule III drugs carry moderate abuse risk, such as codeine combinations or anabolic steroids, a step below oxycodone.
- Schedule I drugs, such as heroin, are considered to have no currently accepted medical use, unlike prescribable oxycodone.
- Schedule V holds the lowest-risk drugs, like low-dose codeine cough syrups, nowhere near oxycodone's abuse potential.
Which of the following is classified as an allied health profession?
Answer & explanation
Answer: D. Radiologic technologist
Allied health covers the diagnostic, technical and therapeutic professions that support physicians and nurses, such as radiologic technologists, medical assistants and phlebotomists. Nursing is a separate licensed profession and is not grouped under allied health. Physicians (MD or DO) and dentists are independent practitioners who direct care rather than support it.
- A DO is a fully licensed physician who diagnoses and treats, so it is not grouped with allied health.
- Nursing is usually counted as its own profession, separate from the allied health disciplines that support physicians and nurses.
- A DDS is a licensed dentist practicing independently, which places dentistry outside the allied health category.
- Correct: radiologic technologists perform imaging under provider orders, a classic allied health role alongside medical assistants and lab technicians.
Which feature best characterizes a Patient-Centered Medical Home (PCMH)?
Answer & explanation
Answer: C. Care is coordinated by a primary care team across the system
A PCMH centers care on a coordinating primary care team that manages prevention and chronic conditions across the whole system. It does not fragment care among specialists or abandon prevention.
- A medical home strengthens the ongoing relationship with a personal clinician rather than replacing it with rigid protocols.
- Prevention and chronic-disease management are core to a PCMH, so an acute-only model is the opposite.
- Correct: a PCMH centers a primary care team that coordinates referrals, follow-up and prevention across the whole health system.
- Uncoordinated specialist care is exactly the fragmentation the medical home model was designed to fix.
The medical term cardiomegaly means:
Answer & explanation
Answer: C. Enlargement of the heart
The suffix -megaly means enlargement, so cardiomegaly is an enlarged heart. Inflammation of the heart would use -itis (carditis), and disease of the heart muscle uses -pathy (cardiomyopathy). A slow heart rate is bradycardia, from the prefix brady-, meaning slow.
- Disease of the heart muscle is cardiomyopathy; the suffix -pathy means disease, not enlargement.
- Inflammation of the heart uses -itis, as in carditis; watch for suffix swaps between look-alike terms.
- Correct: the suffix -megaly means enlargement, so cardi/o plus -megaly describes an enlarged heart.
- A slow heart rate is bradycardia, built from the prefix brady-, which has nothing to do with size.
According to Maslow's hierarchy of needs, which needs must be met before safety needs can be addressed?
Answer & explanation
Answer: A. Physiological needs
Maslow's hierarchy places physiological needs (food, water, air) at the base; they must be satisfied before safety. Belonging, esteem, and self-actualization are higher levels addressed later.
- Correct: physiological needs like air, food, water and sleep form the base of Maslow's pyramid and come before safety.
- Esteem sits fourth in the pyramid, above safety, so it cannot be a prerequisite for safety needs.
- Self-actualization is the top level, reached only after every need below it is reasonably met.
- Belonging and love come after safety in Maslow's order, so they cannot come first.
Fat-soluble vitamins differ from water-soluble vitamins mainly because they:
Answer & explanation
Answer: C. Are stored in the body's tissues
Fat-soluble vitamins (A, D, E, K) are stored in fatty tissue and the liver, so they need not be consumed daily. Water-soluble vitamins are not stored significantly and must be replenished regularly.
- Vitamins A, D, E and K come from many foods, such as dairy, leafy greens and oily fish.
- Heat sensitivity is more typical of some water-soluble vitamins like vitamin C, not a defining trait of fat-soluble ones.
- Correct: fat-soluble vitamins A, D, E and K are stored in liver and fatty tissue, which is why excess can build up.
- Daily intake matters more for water-soluble vitamins, which the body flushes out; fat-soluble ones are stored.
Which of the following is a function of the FDA rather than the CDC?
Answer & explanation
Answer: C. Licensing new vaccines for use
The FDA regulates drugs, vaccines and medical devices and must license a vaccine before it can be marketed. The CDC is the public-health agency: it runs disease surveillance, publishes the ACIP immunization schedules and issues infection-control guidelines such as hand hygiene, but it does not approve vaccines.
- Hand hygiene guidance for healthcare settings comes from the CDC, so this is a CDC function.
- Disease surveillance and outbreak tracking are core CDC work, the classic agency-confusion trap here.
- Correct: the FDA licenses and approves vaccines and drugs before use; the CDC recommends how they are used.
- The CDC, with its advisory committee, publishes the immunization schedules, so this is not an FDA role.
Which federal agency administers the Medicare and Medicaid programs?
Answer & explanation
Answer: D. CMS
The Centers for Medicare & Medicaid Services (CMS) runs Medicare and Medicaid. The CDC handles public-health surveillance, the FDA regulates drugs, and OSHA covers workplace safety.
- The CDC tracks disease and issues public-health guidance; it does not run any insurance program.
- OSHA sets and enforces workplace safety rules, such as the Bloodborne Pathogens Standard, not insurance.
- The FDA approves and regulates drugs, vaccines and devices; payment programs are outside its role.
- Correct: the Centers for Medicare & Medicaid Services runs both programs, as its name suggests.
The suffix '-otomy' in a medical term means:
Answer & explanation
Answer: D. Incision into
'-otomy' means to cut into or make an incision. A new permanent opening is '-ostomy,' removal is '-ectomy,' and visual exam is '-oscopy.'
- Visual examination is -oscopy, as in colonoscopy; the scope looks rather than cuts.
- Surgical removal is -ectomy, as in appendectomy, a different suffix from -otomy.
- A new opening is -ostomy, the look-alike; one extra letter turns a cut into a permanent opening.
- Correct: -otomy means cutting into, as in tracheotomy, without removing anything or leaving a permanent opening.
Which abbreviation appears on The Joint Commission's official 'Do Not Use' list?
Answer & explanation
Answer: A. Q.D. (for daily)
Q.D. is on the 'Do Not Use' list because it can be misread as Q.I.D. (four times daily); 'daily' should be written out. BID, PRN, and NPO are acceptable standard abbreviations.
- Correct: Q.D. is easily misread as Q.I.D. or QOD, so The Joint Commission requires writing out daily instead.
- BID is a standard abbreviation for twice daily and is not on the Joint Commission's official list.
- NPO is widely accepted for nothing by mouth and does not appear on the Do Not Use list.
- PRN for as needed is an accepted abbreviation and is not banned by The Joint Commission.
A staff member meets monthly with a patient to help the patient set personal weight-loss goals and plan realistic steps to reach them. This role is best described as:
Answer & explanation
Answer: C. Health coaching
Health coaching helps patients identify their own goals and builds the motivation and plan to reach them. Patient education is the tempting choice, but it delivers specific information or skills directed by the provider, such as how to use a glucometer. Navigation removes barriers to accessing care, and advocacy means speaking up on the patient's behalf.
- Patient navigators help people move through the system, such as scheduling and access barriers, not personal goal setting.
- Patient education teaches information about a condition or treatment; ongoing goal planning with the patient goes beyond that.
- Correct: health coaching partners with the patient over time to set personal goals and plan realistic behavior changes.
- Advocacy means speaking up for the patient's rights and interests, which is different from coaching lifestyle goals.
A patient scheduled for a cholecystectomy will have:
Answer & explanation
Answer: A. The gallbladder removed
Chol/e (bile) plus cyst/o (sac) names the gallbladder, and -ectomy means surgical removal. An incision without removal would be a cholecystotomy (-otomy). The urinary bladder is a common mix-up because cyst/o alone means bladder, but chole- specifies the bile sac.
- Correct: the suffix -ectomy means surgical removal, and cholecyst/o means gallbladder, so the gallbladder comes out.
- An incision into the gallbladder would be a cholecystotomy; -otomy means cutting into, not removing.
- The urinary bladder is cyst/o alone; the chole- part means bile, pointing to the gallbladder instead.
- A scope exam uses the suffix -scopy, so this describes a different procedure entirely.
A clinic's care model addresses each patient's physical, emotional, social and spiritual needs together rather than only the presenting disease. This approach is called:
Answer & explanation
Answer: D. Holistic care
Holistic care treats the whole person, looking at physical, emotional, social and spiritual needs together, and it can include conventional treatment. Palliative care is tempting because it also attends to emotional needs, but it focuses on comfort and symptom relief in serious illness. Alternative medicine means using a non-conventional therapy in place of standard treatment.
- Alternative medicine uses non-mainstream therapies in place of conventional treatment; it does not define whole-person care.
- Preventive care aims to stop disease before it starts, through screenings and vaccines, not whole-person focus.
- Palliative care focuses on comfort and quality of life in serious illness, a narrower goal than this.
- Correct: holistic care treats the whole person, physical, emotional, social and spiritual, rather than only the disease.
A patient recovering from a stroke is referred to a physiatrist. This specialist focuses on:
Answer & explanation
Answer: D. Rehabilitation and restoring function
A physiatrist is a physician specializing in physical medicine and rehabilitation, restoring function after stroke, injury or surgery. The name is easily confused with psychiatrist (mental health) and podiatrist (foot and ankle). Spinal manipulation is associated with chiropractors.
- Mental and emotional disorders are treated by psychiatrists, a common sound-alike confusion with physiatrists.
- Spinal adjustment and manipulation describe chiropractic care, not the physical medicine specialty.
- Foot and ankle disorders are the work of podiatrists, not physiatrists.
- Correct: physiatrists specialize in physical medicine and rehabilitation, helping stroke patients regain movement and daily function.
A drug's effect lasts much longer in an older adult because the liver breaks it down more slowly. Which pharmacokinetic process has changed?
Answer & explanation
Answer: D. Metabolism
Metabolism is the chemical breakdown of a drug, mainly in the liver, and it slows with age and liver disease. Excretion is the tempting choice, but it is removal of the drug from the body, mainly by the kidneys. Absorption is entry into the bloodstream, and distribution is how the drug spreads to tissues.
- Absorption is how a drug enters the bloodstream; the stem describes breakdown in the liver instead.
- Excretion is removal from the body, mainly by the kidneys, not breakdown by the liver.
- Distribution is how a drug spreads to the tissues after it reaches the blood.
- Correct: metabolism is the liver's chemical breakdown of a drug, and it often slows with age.
A patient with poorly controlled type 1 diabetes who also has a thyroid nodule would most likely be referred to which specialist?
Answer & explanation
Answer: D. Endocrinologist
Endocrinology manages disorders of the hormone-producing glands, including the pancreas (insulin) and the thyroid, so both problems belong there. Nephrology is tempting because diabetes can damage the kidneys, but a nephrologist treats the kidney disease itself. A gastroenterologist treats the digestive tract, and a hematologist treats blood disorders.
- Gastroenterologists treat digestive tract disorders, not the hormonal side of the pancreas or the thyroid.
- Hematologists manage blood disorders, which neither diabetes nor a thyroid nodule represents.
- Nephrologists treat kidney disease; diabetes may affect the kidneys later, but that is not the referral reason here.
- Correct: endocrinologists manage hormone glands, covering both insulin problems in diabetes and thyroid disorders in one referral.
Osteomyelitis is an infection of the:
Answer & explanation
Answer: A. Bone and bone marrow
Oste/o means bone and myel/o means marrow, so osteomyelitis is infection of the bone and its marrow. Muscle is the look-alike trap, because the muscle root is my/o, not myel/o. Myel/o can mean spinal cord on its own, but combined with oste/o it refers to marrow, and cartilage is chondr/o.
- Correct: oste/o means bone, myel/o means marrow and -itis means inflammation, matching infection of bone and marrow.
- Joint cartilage involvement points to terms built on arthr/o or chondr/o, not oste/o.
- Myel/o here means marrow, not muscle; muscle would be my/o, a classic look-alike trap.
- Myel/o can also mean spinal cord, but next to oste/o it points to the marrow inside bone.
A patient who strongly dislikes a coworker keeps insisting, "That coworker hates me." Which defense mechanism is the patient using?
Answer & explanation
Answer: B. Projection
Projection attributes one's own unacceptable feelings to someone else; here the patient's dislike is recast as the coworker's hatred. Displacement is the tempting choice, but it redirects a feeling onto a safer target rather than assigning it to another person. Denial refuses to accept reality, and reaction formation shows the opposite of the true feeling, such as being overly friendly to the coworker.
- Denial refuses to accept a painful reality; this patient is reassigning a feeling instead.
- Correct: projection puts your own unacceptable feeling onto someone else, so dislike becomes 'they hate me.'
- Displacement redirects a feeling onto a safer target, but the feeling is still owned as one's own.
- Reaction formation would look like the opposite, such as being overly friendly to the disliked coworker.
To help lower LDL cholesterol, a patient should mainly reduce intake of:
Answer & explanation
Answer: C. Saturated and trans fats
Saturated fats (fatty meats, butter) and trans fats raise LDL cholesterol and cardiovascular risk. Monounsaturated fats, such as olive oil, are the tempting choice because they are fats, but they help lower LDL when they replace saturated fat. Omega-3 fatty acids from fish are heart-protective, and complex carbohydrates such as whole grains do not raise LDL.
- Whole grains are encouraged in heart-healthy eating and do not raise LDL cholesterol.
- Monounsaturated fats, such as olive oil, can help lower LDL when they replace saturated fat.
- Correct: saturated fats from fatty meat and butter, plus trans fats, raise LDL the most.
- Omega-3 fats from fish are heart-protective, so they are not the ones to cut back.
A patient's respiratory rate is 8 breaths per minute. Which term describes this?
Answer & explanation
Answer: C. Bradypnea
Brady- means slow and -pnea means breathing; 8/min is below the adult normal of 12 to 20. Tachypnea is fast breathing (tachy- means fast), the opposite error. Dyspnea is difficult breathing and apnea is absence of breathing, and neither describes the rate.
- Apnea means no breathing at all, so a rate of 8 is slow but not absent.
- Dyspnea means difficult or labored breathing, which describes effort rather than rate.
- Correct: bradypnea means abnormally slow breathing, below the normal adult range of 12 to 20 per minute.
- Tachypnea means rapid breathing above 20 per minute, the opposite of a rate of 8.
That is the whole set. Open any card to re-read its explanation, or start over.
