Certified Medical Assistant (CMA AAMA) practice test questions

Sample questions from the 224-question bank, with answers and explanations.

All questions
  1. 1. During a mass casualty incident, a first responder using the START triage method encounters a patient who is not breathing even after the airway is repositioned. According to START triage protocol, how should this patient be categorized?

    Clinical Workflow and Patient Intake

    • A. Green - minor
    • B. Yellow - delayed
    • C. Red - immediate
    • D. Black - deceased/expectant
    Show answer

    D. Black - deceased/expectant

    In the START (Simple Triage and Rapid Treatment) system, a patient who remains apneic after airway repositioning is categorized as black, indicating deceased or expectant (non-salvageable given available resources). This allows responders to prioritize resources toward salvageable patients.

  2. 2. A 6-week-old infant is brought to the office with a fever. Which method of temperature measurement is considered most accurate for this patient?

    Clinical Workflow and Patient Intake

    • A. Rectal
    • B. Tympanic
    • C. Oral
    • D. Axillary
    Show answer

    A. Rectal

    Rectal temperature measurement is considered the most accurate method for infants under 3 months of age because their small ear canals make tympanic readings unreliable, and oral measurement is not feasible. Rectal readings most closely reflect core body temperature.

  3. 3. A patient presents for a point-of-care urine hCG pregnancy test. The result shows only a faint colored line in the control region with no line in the test region after the recommended reading time. How should this result be interpreted?

    Procedures, Examinations and Diagnostics

    • A. Positive for pregnancy
    • B. Indeterminate, requires a serum hCG confirmation
    • C. Negative for pregnancy
    • D. Invalid, the test must be repeated
    Show answer

    C. Negative for pregnancy

    A visible control line confirms the test is working correctly; the absence of a line in the test region indicates a negative result. The test is valid because the control line appeared, ruling out an invalid result.

  4. 4. A patient's tympanic temperature reads 38.5°C. What is this temperature in degrees Fahrenheit?

    Clinical Workflow and Patient Intake

    • A. 97.7°F
    • B. 100.4°F
    • C. 101.3°F
    • D. 99.1°F
    Show answer

    C. 101.3°F

    Using the formula F = (C × 9/5) + 32: (38.5 × 1.8) + 32 = 69.3 + 32 = 101.3°F. This confirms the patient has a fever, since normal body temperature is approximately 98.6°F (37°C).

  5. 5. A medical assistant collects a venous blood specimen from a patient. At what point should the specimen tube be labeled with the patient's identifying information?

    Procedures, Examinations and Diagnostics

    • A. After transporting the specimen to the reference laboratory
    • B. After centrifuging the specimen in the lab
    • C. Immediately after collection, while still at the patient's side
    • D. Before drawing the blood, using a pre-printed label on the tray
    Show answer

    C. Immediately after collection, while still at the patient's side

    Specimen tubes must be labeled immediately after collection while the medical assistant is still with the patient, verifying patient identity before leaving the bedside to prevent mislabeling errors.

  6. 6. A medical assistant is preparing to obtain a pulse oximetry reading on a patient who has nail polish on her fingers and cold hands. What should the medical assistant do to ensure an accurate reading?

    Clinical Workflow and Patient Intake

    • A. Warm the fingers only, since nail polish has no effect
    • B. Proceed as usual since nail polish does not affect readings
    • C. Document the reading with a note that it may be inaccurate
    • D. Remove nail polish or use an alternate site such as the earlobe
    Show answer

    D. Remove nail polish or use an alternate site such as the earlobe

    Dark nail polish can interfere with light absorption in pulse oximetry sensors, and cold extremities reduce peripheral perfusion, both leading to inaccurate readings. Removing polish or using an alternate site such as the earlobe helps ensure accuracy.

  7. 7. A medical assistant is performing daily quality control on a point-of-care glucose meter using both a low-level and a high-level control solution. The low control result falls within the acceptable range, but the high control result falls outside the acceptable range. What should the medical assistant do next?

    Procedures, Examinations and Diagnostics

    • A. Do not report patient results; troubleshoot the meter and repeat QC before patient testing
    • B. Repeat only the low control test to confirm meter accuracy
    • C. Report patient glucose results as usual since the low control passed
    • D. Average the two control results and use that value to validate the meter
    Show answer

    A. Do not report patient results; troubleshoot the meter and repeat QC before patient testing

    If either control level fails QC, the meter cannot be considered reliable and must not be used for patient testing until the problem is identified and resolved and QC passes at both levels. Passing one control level does not compensate for failure at another level.

  8. 8. A medical assistant is drawing a coagulation study and must fill a light blue-top tube. Why is it essential that this tube be filled to its exact volume mark?

    Procedures, Examinations and Diagnostics

    • A. To maintain the correct 9:1 ratio of blood to sodium citrate anticoagulant
    • B. To ensure enough serum separates during centrifugation
    • C. To prevent glycolysis from falsely lowering glucose results
    • D. To prevent hemoconcentration from a prolonged tourniquet application
    Show answer

    A. To maintain the correct 9:1 ratio of blood to sodium citrate anticoagulant

    Light blue-top tubes contain sodium citrate anticoagulant in a fixed volume, and they must be filled completely to maintain the correct 9:1 blood-to-anticoagulant ratio; underfilling causes an excess of citrate relative to blood, which can falsely prolong coagulation results such as PT/PTT.

  9. 9. A medical assistant asks an adult patient to rate their pain using a numeric scale. The patient states their pain is an 8. On a standard 0-10 numeric pain rating scale, this score indicates which level of pain?

    Clinical Workflow and Patient Intake

    • A. Mild pain
    • B. Moderate pain
    • C. Severe pain
    • D. No pain
    Show answer

    C. Severe pain

    On the standard 0-10 numeric pain rating scale, 0 indicates no pain, 1-3 mild pain, 4-6 moderate pain, and 7-10 severe pain. A score of 8 falls into the severe pain category.

  10. 10. A medical assistant is rooming a patient and reviewing the medication list from the previous visit. The patient states they stopped taking lisinopril two months ago due to a cough and started taking an herbal supplement instead. What is the medical assistant's most appropriate action?

    Clinical Workflow and Patient Intake

    • A. Leave the medication list unchanged since the physician will review it
    • B. Document only the herbal supplement and remove all reference to lisinopril
    • C. Advise the patient to resume the lisinopril immediately
    • D. Update the medication list to reflect the discontinued medication and add the new supplement
    Show answer

    D. Update the medication list to reflect the discontinued medication and add the new supplement

    Medication reconciliation requires accurately updating the current medication list at each visit, including discontinued medications and new supplements, so the provider has complete and current information.

  11. 11. A medical assistant is instructed to use the Z-track injection technique when administering iron dextran intramuscularly. What is the primary purpose of this technique?

    Pharmacology

    • A. To reduce the volume of medication needed
    • B. To prevent leakage of the medication into subcutaneous tissue and skin staining
    • C. To allow for a smaller gauge needle to be used
    • D. To increase the speed of drug absorption
    Show answer

    B. To prevent leakage of the medication into subcutaneous tissue and skin staining

    The Z-track technique displaces the skin and subcutaneous tissue laterally before injection, then releases it after withdrawal of the needle, sealing the medication within the muscle. This prevents the irritating or staining medication (such as iron dextran) from leaking back through the injection tract into subcutaneous tissue or skin.

  12. 12. A medical assistant is placing limb lead electrodes for a 12-lead EKG. According to standard color coding, which electrode placement is correct?

    Procedures, Examinations and Diagnostics

    • A. Green electrode on the left arm
    • B. White electrode on the right arm
    • C. Red electrode on the right leg
    • D. Black electrode on the left leg
    Show answer

    B. White electrode on the right arm

    The standard AHA color code places white on the right arm, black on the left arm, green on the right leg, and red on the left leg. Correct lead placement is essential for accurate waveform interpretation.

  13. 13. A medical assistant is obtaining vital signs on a healthy 30-year-old patient at rest. Which respiratory rate falls within the normal adult range?

    Clinical Workflow and Patient Intake

    • A. 16 breaths/min
    • B. 32 breaths/min
    • C. 8 breaths/min
    • D. 26 breaths/min
    Show answer

    A. 16 breaths/min

    The normal resting respiratory rate for an adult is 12–20 breaths per minute, so 16 breaths/min is within normal limits. Rates below 12 (bradypnea) or above 20 (tachypnea) are abnormal.

  14. 14. During a 12-lead EKG, a medical assistant is placing the chest electrodes. Where should lead V6 be positioned?

    Procedures, Examinations and Diagnostics

    • A. Fifth intercostal space, left midclavicular line
    • B. Left midaxillary line, same horizontal level as V4
    • C. Between V2 and V4, directly over the sternum
    • D. Fourth intercostal space, right sternal border
    Show answer

    B. Left midaxillary line, same horizontal level as V4

    V6 is placed at the left midaxillary line, on the same horizontal level as V4 and V5. V1 is at the fourth intercostal space at the right sternal border, and V4 is at the fifth intercostal space, left midclavicular line.

  15. 15. A physician orders a patient to sit upright with the head of the exam table elevated 90 degrees to relieve shortness of breath during an assessment. Which position is being used?

    Procedures, Examinations and Diagnostics

    • A. Dorsal recumbent position
    • B. Trendelenburg position
    • C. Sims position
    • D. Fowler's position
    Show answer

    D. Fowler's position

    Fowler's position involves sitting the patient upright at a 90-degree angle, which is commonly used for patients with respiratory distress because it allows for maximal lung expansion.

  16. 16. Before using a point-of-care glucose meter for patient testing each day, a medical assistant should first run which of the following?

    Procedures, Examinations and Diagnostics

    • A. A patient sample from the previous shift
    • B. A new lot number verification only once per year
    • C. A confirmatory venous blood draw
    • D. Liquid quality control solutions at two different levels
    Show answer

    D. Liquid quality control solutions at two different levels

    CLIA-waived point-of-care testing requires running liquid quality control material at both normal and abnormal (high/low) levels according to the schedule set by the facility (often daily) to verify the meter and test strips are functioning correctly before patient testing.

  17. 17. When administering a subcutaneous injection to an average-weight adult, which needle length and insertion angle is most appropriate?

    Pharmacology

    • A. 1.5 inch needle at a 90-degree angle
    • B. 5/8 inch needle at a 45-degree angle
    • C. 1 inch needle at a 90-degree angle
    • D. 1 inch needle at a 15-degree angle
    Show answer

    B. 5/8 inch needle at a 45-degree angle

    Subcutaneous injections are given into the fatty tissue just below the skin, typically using a short 5/8 inch needle inserted at a 45-degree angle (or 90 degrees for a pinched fold in obese patients). Longer needles and steeper angles are used for intramuscular injections, which must reach deeper muscle tissue.

  18. 18. A medical assistant places all 12 leads for an EKG and notices that lead aVR shows a predominantly upright (positive) QRS complex, which is unusual. What does this most likely indicate?

    Procedures, Examinations and Diagnostics

    • A. An indication that the patient is experiencing a myocardial infarction
    • B. Normal sinus rhythm with no cause for concern
    • C. Correct placement confirming accurate limb lead positioning
    • D. Possible reversal of the right arm and left arm electrodes
    Show answer

    D. Possible reversal of the right arm and left arm electrodes

    Lead aVR normally displays a negative deflection because it views the heart from the right shoulder, away from the main electrical vector. A positive aVR complex is a classic sign of arm lead reversal and should prompt a recheck of electrode placement before assuming a cardiac abnormality.

  19. 19. A physician orders a rectal examination requiring the patient to kneel on the table with the chest and shoulders down and buttocks raised. Which position is the medical assistant preparing?

    Procedures, Examinations and Diagnostics

    • A. Lithotomy position
    • B. Sims' position
    • C. Knee-chest position
    • D. Trendelenburg position
    Show answer

    C. Knee-chest position

    The knee-chest position involves the patient kneeling with the chest and shoulders resting on the table and the buttocks elevated, commonly used for rectal, proctologic, or sigmoidoscopy exams. Lithotomy is used for pelvic exams, Sims' for lateral rectal exams, and Trendelenburg for shock treatment.

  20. 20. A patient stands up after sitting for several minutes. Their blood pressure drops from 128/78 mmHg while seated to 104/70 mmHg while standing, and they report dizziness. This finding is most consistent with:

    Clinical Workflow and Patient Intake

    • A. hypertensive urgency
    • B. orthostatic hypotension
    • C. pulsus paradoxus
    • D. normal physiologic variation
    Show answer

    B. orthostatic hypotension

    Orthostatic hypotension is diagnosed when systolic blood pressure drops by 20 mmHg or more (or diastolic drops by 10 mmHg or more) within a few minutes of standing, often accompanied by dizziness. Here, systolic dropped 24 mmHg (128−104), meeting the diagnostic threshold.

  21. 21. A medical assistant palpates the radial pulse at 76 beats per minute while a colleague simultaneously auscultates the apical pulse at 88 beats per minute for one full minute. What is the pulse deficit?

    Clinical Workflow and Patient Intake

    • A. 6 beats/min
    • B. 12 beats/min
    • C. 76 beats/min
    • D. 164 beats/min
    Show answer

    B. 12 beats/min

    Pulse deficit is calculated by subtracting the radial pulse from the apical pulse: 88 − 76 = 12 beats/min. A pulse deficit indicates that some heartbeats are not producing a palpable peripheral pulse, which can suggest cardiac arrhythmia.

  22. 22. A physician orders a pelvic examination with speculum insertion. Which patient position should the medical assistant prepare?

    Procedures, Examinations and Diagnostics

    • A. Lithotomy position
    • B. Trendelenburg position
    • C. Fowler position
    • D. Sims position
    Show answer

    A. Lithotomy position

    The lithotomy position, with the patient supine, hips and knees flexed, and feet in stirrups, provides optimal access for pelvic and vaginal examinations, including speculum insertion.

  23. 23. A medical assistant draws a blood specimen and notices the sample appears pink-tinged in the serum after centrifugation. Which technique error during the draw most likely caused this result?

    Procedures, Examinations and Diagnostics

    • A. Vigorously shaking the tube immediately after collection
    • B. Applying the tourniquet for less than 30 seconds
    • C. Using a 21-gauge needle for the venipuncture
    • D. Allowing the tube to fill completely with correct additive ratio
    Show answer

    A. Vigorously shaking the tube immediately after collection

    Vigorous shaking of a blood tube causes mechanical trauma to red blood cells, releasing hemoglobin into the plasma or serum and producing a pink or red-tinged appearance known as hemolysis, which can invalidate many chemistry results.

  24. 24. A medical assistant is preparing to room a new patient. Which action should be performed first?

    Clinical Workflow and Patient Intake

    • A. Document the chief complaint
    • B. Greet the patient and confirm identity
    • C. Ask the patient to change into a gown
    • D. Measure and record vital signs
    Show answer

    B. Greet the patient and confirm identity

    The rooming process begins with greeting the patient and confirming identity to ensure patient safety and rapport before proceeding with data collection or preparation. Vital signs, chief complaint, and gowning occur afterward in sequence.

  25. 25. A medical assistant obtains a pulse rate of 130 beats per minute on a healthy, calm 6-month-old infant during a well-child visit. How should this finding be interpreted?

    Clinical Workflow and Patient Intake

    • A. Within the normal range for an infant this age
    • B. Bradycardic and should be rechecked in 10 minutes
    • C. Tachycardic and requires immediate physician notification
    • D. Abnormal only if respiratory rate is also elevated
    Show answer

    A. Within the normal range for an infant this age

    Normal heart rate for infants (age 1–12 months) ranges from approximately 100 to 160 beats per minute. A pulse of 130 bpm in a calm, healthy infant is within normal limits and requires no intervention.
