, SECTION I — CCMA 2024 NHA PRACTICE EXAMINATION Questions 1 – 100
1. An apical pulse is the preferred method of pulse measurement for which patient
population?
A. Infants and young children
B. Children over four years old
C. Adolescents
D. Young adults (20–40)
CORRECT ANSWER A — Infants and young children
RATIONALE The apical pulse is preferred for infants and young children because their
peripheral pulses are difficult to palpate accurately. It is auscultated over the apex
of the heart using a stethoscope. It is also used for patients with irregular heart
rhythms and when radial pulse cannot be obtained accurately.
2. Clinical signs and concerns of a head injury could include which of the following?
A. Vomiting
B. Headache
C. Confusion
D. All answers are correct
CORRECT ANSWER D — All answers are correct
RATIONALE Head injuries can present with vomiting, headache, and confusion — all
concerning signs. Other red flags include loss of consciousness, unequal pupils,
clear fluid drainage from nose/ears, seizures, and worsening symptoms. Any
combination warrants immediate medical evaluation as a potential neurosurgical
emergency.
,3. What is the function of a centrifuge in the clinical laboratory?
A. It freezes specimens
B. It heats specimens
C. It is used for incubation of specimens
D. It separates the cellular and liquid portions of the blood
CORRECT ANSWER D — It separates the cellular and liquid portions of the blood
RATIONALE A centrifuge spins blood tubes at high speed, using centrifugal force to separate
heavier cellular components (RBCs, WBCs, platelets) from the lighter liquid
portion (plasma or serum). This separation is essential for many laboratory tests.
It does not freeze, heat, or incubate specimens.
4. Which needle gauges are most commonly used for routine venipuncture?
A. 24–25 G
B. 21–22 G
C. 19–20 G
D. 16–18 G
CORRECT ANSWER B — 21–22 G
RATIONALE The 21–22 gauge needle is the standard for routine venipuncture in adults. It
provides adequate blood flow without causing hemolysis. Smaller gauges (23–25
G) are for fragile/small veins but can cause hemolysis. Larger gauges (16–18 G) are
for blood donation. The phlebotomist selects gauge based on vein size and test
requirements.
, 5. Blood pressure should NOT be taken on an arm in which of the following situations?
A. The patient has had breast surgery on that side
B. On the arm with an IV infusion
C. On the arm with a cast
D. All answers are correct
CORRECT ANSWER D — All answers are correct
RATIONALE BP should NOT be taken on an arm with a mastectomy history (risk of
lymphedema), an active IV infusion (fluid can affect readings and BP cuff can
dislodge IV), or a cast (unable to compress artery properly). All are
contraindications, and the MA must use the opposite arm or the thigh as an
alternative site.
6. What does the acronym "HIV" stand for?
A. Hepatitis B Virus
B. Hepatitis C Virus
C. Human Immunodeficiency Virus
D. Human Infectious Virus
CORRECT ANSWER C — Human Immunodeficiency Virus
RATIONALE HIV stands for Human Immunodeficiency Virus — the virus that attacks the body's
immune system (CD4 T cells) and can progress to AIDS. It is a bloodborne
pathogen transmitted through blood, sexual contact, and from mother to child.
HBV and HCV are hepatitis viruses. "Human Infectious Virus" is not a medical
term.
