NHA Certified Clinical Medical Assistant (CCMA)
Practice Exam
1. A medical assistant is preparing to perform a venipuncture on a patient with small, fragile
veins. Which of the following pieces of equipment is the most appropriate choice?
A. 23-gauge winged infusion set with a syringe
B. 21-gauge needle with a vacuum tube
C. 18-gauge needle with a evacuated tube system
D. Capillary puncture lancet
Correct Answer: A
Explanation: The 23-gauge winged infusion set, also known as a butterfly needle, allows
for more control and less pressure on fragile veins, preventing them from collapsing. Using
a syringe allows the medical assistant to manually control the vacuum pressure applied to
the vein during the draw. A 21-gauge or 18-gauge needle would be too large and likely
cause vessel rupture, while a capillary puncture might not provide enough volume for the
required tests.
2. A patient presents with a fever, body aches, and cough. The physician orders a rapid
influenza test. Which of the following specimen collection methods should the medical
assistant use?
A. Midstream clean-catch urine
,B. Expectorated sputum sample
C. Nasopharyngeal swab
D. Oropharyngeal swab
Correct Answer: C
Explanation: Rapid influenza diagnostic tests (RIDTs) typically require a nasopharyngeal
swab to collect viral antigens from the posterior nasal cavity where the virus replicates.
Nasopharyngeal swabs are the gold standard for respiratory virus detection compared to
simple throat swabs. Sputum is used for bacterial lung infections, and urine is not
appropriate for respiratory virus detection.
3. When performing a 12-lead EKG, where should the medical assistant place the V4
electrode?
A. Fourth intercostal space, right sternal border
B. Fourth intercostal space, left sternal border
C. Fifth intercostal space, anterior axillary line
D. Fifth intercostal space, midclavicular line
Correct Answer: D
Explanation: Electrode V4 is placed in the fifth intercostal space at the midclavicular line
to capture the electrical activity of the apex of the heart. Correct placement is vital to
, ensure an accurate tracing and avoid misdiagnosis of cardiac conditions. Options A and B
represent V1 and V2, respectively, while D represents V5.
4. A medical assistant is assisting a provider with a sterile minor surgical procedure. Which of
the following actions maintains the sterile field?
A. Reaching across the sterile field to pick up a tool
B. Placing sterile items on the 1-inch border of the sterile drape
C. Opening the sterile pack with the first flap opening away from the assistant
D. Keeping hands below the waist level while wearing sterile gloves
Correct Answer: C
Explanation: Sterile technique requires opening the first flap of a sterile tray away from
the body to prevent reaching over the sterile contents. The 1-inch border of a sterile field is
considered contaminated and should not be used for sterile items. Keeping hands below
the waist or reaching across the field are major breaks in sterile technique that increase the
risk of surgical site infections.
5. Which of the following describes the correct technique for measuring a patient’s blood
pressure?
A. Position the patient’s arm above the level of the heart
B. Ensure the bladder of the cuff encircles 50% of the arm circumference
C. Deflate the cuff at a rate of 2 to 3 mmHg per second
