CMA Full Topic Test: Clinical & Administrative Competencies
1. A patient presents to the urgent care clinic complaining of
acute chest tightness and dyspnea. The Certified Medical
Assistant (CMA) immediately rooms the patient and prepares
to perform a standard 12-lead electrocardiogram (ECG). While
placing the precordial electrodes, which of the following
describes the correct anatomical placement for the V4 lead?
A. Fourth intercostal space at the right border of the sternum.
B. Fourth intercostal space at the left border of the sternum.
C. Fifth intercostal space at the left anterior axillary line.
D. Fifth intercostal space at the left midclavicular line.
Correct Answer: D
Rationale: Lead V4 must be placed precisely at the fifth intercostal
space along the left midclavicular line. Option A describes V1, Option B
describes V2, and Option C describes V5. Correct anatomical placement
is critical to prevent waveform distortion and diagnostic errors.
2. A CMA is performing a routine venipuncture on an adult
patient to collect a Complete Blood Count (CBC) and a
Prothrombin Time (PT/INR). To ensure accurate laboratory
results and prevent cross-contamination of additives, which
tube collection order must the medical assistant follow?
A. Lavender top tube first, followed by the Light Blue top tube.
B. Light Blue top tube first, followed by the Lavender top tube.
C. Serum Separator Tube (SST) first, followed by the Light Blue top tube.
D. Green top tube first, followed by the Light Blue top tube.
,Correct Answer: B
Rationale: According to the CLSI order of draw, coagulation tubes
(Light Blue, containing sodium citrate) must be filled before
hematology tubes (Lavender, containing EDTA). Drawing Lavender
first can cause EDTA carryover, which binds calcium and falsely
elevates clotting times in the PT/INR test.
3. A 45-year-old male patient with a history of chronic
hypertension is being evaluated in the clinic. The physician
requests a blood pressure reading. To avoid obtaining a falsely
elevated systolic or diastolic measurement, which technique
should the CMA employ during auscultation?
A. Deflate the sphygmomanometer cuff rapidly at a rate of 10 mm Hg per
second.
B. Position the patient's arm so that the antecubital fossa rests well
above heart level.
C. Ensure the cuff bladder encircles 80% of the patient's upper
arm circumference.
D. Wrap the cuff loosely over a thick sweater sleeve to maintain patient
warmth.
Correct Answer: C
Rationale: A blood pressure cuff bladder must encircle at least 80% of
an adult's arm circumference to deliver uniform compression. A cuff
that is too small or wrapped loosely causes falsely elevated readings.
Deflating too rapidly or placing the arm above heart level causes
falsely low readings.
4. While managing the daily administrative tasks of a busy
family practice, a CMA receives a phone call from an insurance
representative requesting the clinical documentation for a
patient's recent orthopedic surgery. Under the HIPAA Privacy
Rule, what must the CMA verify before releasing this protected
health information (PHI)?
A. The verbal consent of the patient's immediate spouse or legal family
member.
B. A valid, signed authorization form from the patient
specifying the records to be released.
,C. The insurance company's official corporate tax identification number.
D. A direct verbal confirmation from the attending orthopedic surgeon.
Correct Answer: B
Rationale: HIPAA requires explicit, written authorization from the
patient before releasing PHI to third parties for purposes outside
routine treatment, payment, or healthcare operations, unless a specific
regulatory exception applies. Verbal consent from a spouse is legally
insufficient.
5. A CMA is preparing to administer an intramuscular (IM)
injection of an antibiotic to an obese adult patient. The
physician orders 2 mL of the medication. Which injection site
and needle gauge combination is the most appropriate choice
for this specific clinical scenario?
A. Ventrogluteal site using a 21-gauge, 1.5-inch needle.
B. Deltoid muscle using a 25-gauge, 5/8-inch needle.
C. Vastus lateralis site using a 27-gauge, 0.5-inch needle.
D. Intradermal border using a 20-gauge, 2-inch needle.
Correct Answer: A
Rationale: The ventrogluteal site is preferred for deep IM injections of
up to 3 mL in adults. An obese patient requires a 1.5-inch needle to
ensure the medication penetrates past the subcutaneous adipose tissue
layer into the muscle bed. A 5/8-inch needle is too short.
6. During a minor surgical procedure in the office, the
physician accidentally contaminates their sterile gloves. If the
CMA is acting as the sterile circulator, which action is
appropriate to assist the physician while maintaining the
sterile field?
A. Open a new package of sterile gloves and slide them onto the
physician's hands directly.
B. Wash the contaminated gloves with isopropyl alcohol and dry them
with sterile gauze.
C. Open a new sterile glove package aseptically by peeling the
outer wrapper back without touching the inner contents.
, D. Hand the physician a clean pair of non-sterile examination gloves
from the wall dispenser.
Correct Answer: C
Rationale: The unsterile assistant must open sterile supplies using an
aseptic peeling technique, presenting the sterile inner package to the
sterile field or surgeon without making direct contact. Non-sterile
examination gloves destroy the sterile surgical field.
7. A patient drops off a urine specimen for a routine urinalysis
and physical examination. The CMA notes that the specimen
cannot be processed immediately because the laboratory
technician is on a lunch break. What is the most appropriate
storage protocol for this specimen?
A. Leave the specimen container on the counter at room temperature for
up to four hours.
B. Refrigerate the urine specimen at 4°C (39°F) and process it
within two hours of collection if possible.
C. Place the urine specimen inside an incubator at 37°C (98.6°F) to
prevent bacterial die-off.
D. Freeze the specimen immediately at -20°C to lock the cellular
components in place.
Correct Answer: B
Rationale: If urine cannot be tested within one hour of collection, it
must be refrigerated to prevent bacterial overgrowth, pH alterations,
and the degradation of cellular casts and elements. Incubation
increases bacterial growth, and freezing destroys cells.
8. An elderly female patient falls in the waiting room and
sustains a deep laceration on her right forearm that is
bleeding profusely. After activating emergency protocols, what
is the immediate first-aid intervention the CMA must
perform?
A. Apply a firm tourniquet two inches proximal to the active laceration
site.
B. Apply direct, continuous pressure to the wound using a
clean, sterile dressing.
