CCMA DIAGNOSTIC PRETEST WITH
CORRECT ACTUAL QUESTIONS
AND CORRECTLY WELL DEFINED
ANSWERS ALREADY GRADED A+
(2026/2027)
Introduction
Passing the Certified Clinical Medical Assistant (CCMA) exam from the National
Healthcareer Association (NHA) is a critical step toward a rewarding career in
ambulatory care. This guide provides 200 exam-style practice questions that
mirror the content, difficulty, and format of the actual NHA CCMA test. Each
question includes a correct answer in bold italic and an italicized rationale that
explains the clinical reasoning behind the answer – helping you learn not
just what is correct, but why.
Questions 1–50: Clinical Patient Care
1. What is the first action a medical assistant should take when a patient
experiences chest pain during a stress test?
A) Apply a cold compress
,B) Administer sublingual nitroglycerin
C) Stop the test and assess vital signs
Rationale: Stopping the stress test immediately prevents cardiac overload.
Assessing vital signs (pulse, BP, SpO2) determines stability before further
intervention.
2. Which injection site is preferred for an intramuscular (IM) injection of 1.5 mL in
an adult?
A) Deltoid
B) Ventrogluteal
C) Dorsogluteal
Rationale: Ventrogluteal is recommended for volumes up to 3 mL due to thick
muscle mass and lack of major nerves. Dorsogluteal risks sciatic nerve injury.
3. A patient has a temperature of 101.2°F (38.4°C) orally. What is the correct
documentation?
A) Afebrile
B) Febrile, low-grade
C) Hyperpyrexia
*Rationale: Oral temperatures >100.4°F (38°C) are febrile. 101.2°F is low-grade
fever (100.4–102.2°F). Hyperpyrexia is >106°F.*
4. During a routine physical, you note a patient’s radial pulse is 52 bpm and
irregular. What should you do?
A) Count for 15 seconds and multiply by 4
B) Count for a full 60 seconds
C) Use an automatic wrist cuff
*Rationale: Irregular pulse requires a full 60-second auscultation for accurate rate
and pattern detection. Short counts amplify errors.*
5. Which PPE combination is required when assisting with a sterile dressing change
on a post-op wound?
,A) Gloves only
B) Sterile gloves and mask
C) Non-sterile gloves and gown
Rationale: Sterile gloves prevent wound contamination. A mask is required if
wound is near provider’s face or splash risk exists (standard precaution).
6. What is the normal range for adult respiratory rate at rest?
A) 12–20 breaths/min
*Rationale: 12–20 is standard. <10 = bradypnea, >24 = tachypnea.*
7. A patient reports a penicillin allergy. Which antibiotic class should you alert the
provider to avoid?
A) Cephalosporins
*Rationale: 1–10% cross-sensitivity between penicillins and cephalosporins exists. Avoid
unless provider explicitly approves.*
8. When applying a non-rebreather mask, what O2 flow rate is needed?
A) 10–15 L/min
*Rationale: Low flow (<6 L/min) fails to collapse reservoir bag, causing CO2
rebreathing. 10–15 L/min keeps bag 2/3 full.*
9. Which pulse site is used for an infant’s apical heart rate?
A) Left midclavicular line, 4th intercostal space
Rationale: Infants have rapid, irregular rhythms. Apical auscultation (1 minute) is
gold standard. Brachial is for BP.
10. What does a positive Murphy’s sign indicate?
A) Cholecystitis
Rationale: Pain with palpation of right upper quadrant during inspiration
indicates inflamed gallbladder (stops inspiration).
11. A patient with diabetes has a fingerstick glucose of 65 mg/dL and is sweating.
What should you administer immediately?
, A) 15g of fast-acting carbohydrate
*Rationale: Hypoglycemia (<70 mg/dL). “Rule of 15”: 15g carbs (4 oz juice, 3
glucose tabs), recheck in 15 min. Glucagon for unconscious.*
12. What is the correct angle for a subcutaneous injection?
A) 45 to 90 degrees
Rationale: 45° for thin patients (pinch skin), 90° for average or obese. Intradermal
is 10–15°, IM is 90°.
13. When measuring blood pressure, the cuff should be placed over which artery?
A) Brachial artery
Rationale: Brachial artery at antecubital fossa. Cuff bladder should encircle 80% of
arm.
14. Which finding indicates proper placement of a pulse oximeter probe?
A) Perfusion index >1% and plethysmograph waveform
Rationale: Good waveform confirms arterial pulsation. Nail polish, cold fingers, or
movement cause errors.
15. A patient’s SpO2 is 88% on room air. What should you do first?
A) Apply supplemental oxygen at 2 L/min via nasal cannula
*Rationale: SpO2 <90% is hypoxemia. Start low-flow oxygen and notify provider.
Do not delay oxygen.*
16. What is the normal adult oral temperature range?
A) 97.6–99.6°F (36.4–37.6°C)
Rationale: Average is 98.6°F (37°C). Rectal is 0.5–1°F higher; axillary is 0.5–1°F
lower.
17. Which of the following is a sign of anaphylaxis?
A) Urticaria and stridor
Rationale: Urticaria (hives) + stridor (upper airway swelling) indicate anaphylaxis.
Epinephrine is first-line treatment.
