NWCA Medical Assistant Final Exam Practice
Questions and Answers
Question 1
Which of the following is the most appropriate needle gauge for intramuscular
injections?
A. 16 gauge
B. 18 gauge
C. 22 gauge
D. 25 gauge
Rationale: Intramuscular injections typically require a 22–25 gauge needle. A 22 gauge
is commonly used because it balances strength and patient comfort.
Question 2
What is the primary purpose of HIPAA in healthcare?
A. To regulate medical billing codes
B. To protect patient privacy and health information
C. To establish infection control standards
D. To monitor physician licensing
Rationale: HIPAA ensures confidentiality and security of patient health records,
preventing unauthorized disclosure.
Question 3
Which vital sign is most directly affected by hypoxia?
A. Temperature
B. Respiratory rate
C. Blood pressure
D. Pulse
Rationale: Hypoxia stimulates chemoreceptors, increasing respiratory rate as the body
attempts to compensate for low oxygen levels.
Question 4
Which of the following is considered a subjective symptom?
A. Fever of 101°F
B. Rash on the arm
C. Patient reports dizziness
D. Blood pressure of 140/90
Rationale: Subjective symptoms are reported by the patient and cannot be directly
measured, unlike objective signs such as fever or blood pressure.
Question 5
What is the correct angle for a subcutaneous injection?
,A. 15°
B. 45°
C. 90°
D. 120°
Rationale: Subcutaneous injections are typically administered at a 45° angle to deposit
medication into the fatty tissue beneath the skin.
Question 6
Which of the following is the first step in the chain of infection?
A. Mode of transmission
B. Susceptible host
C. Infectious agent
D. Portal of entry
Rationale: The chain of infection begins with the presence of an infectious agent,
followed by reservoir, portal of exit, transmission, portal of entry, and susceptible host.
Question 7
Which laboratory test is used to monitor long-term glucose control in diabetic patients?
A. Fasting blood sugar
B. Oral glucose tolerance test
C. Hemoglobin A1c
D. Random blood sugar
Rationale: Hemoglobin A1c reflects average blood glucose levels over 2–3 months,
making it the gold standard for monitoring diabetes control.
Question 8
Which of the following is NOT a function of the medical assistant?
A. Administering medications as directed
B. Performing minor surgical procedures independently
C. Recording patient vital signs
D. Assisting with patient education
Rationale: Medical assistants assist physicians but do not perform surgical procedures
independently.
Question 9
Which of the following is the correct compression-to-breath ratio for adult CPR?
A. 15:2
B. 30:2
C. 10:1
D. 20:5
Rationale: Current CPR guidelines recommend 30 chest compressions followed by 2
rescue breaths for adults.
Question 10
Which of the following is the most accurate site for measuring core body temperature?
A. Oral
, B. Axillary
C. Rectal
D. Tympanic
Rationale: Rectal temperature is closest to core body temperature and is considered the
most accurate method.
Question 11
Which of the following is the most common site for venipuncture?
A. Radial artery
B. Median cubital vein
C. Basilic vein
D. Femoral vein
Rationale: The median cubital vein is preferred for venipuncture because it is large,
superficial, and less likely to cause complications.
Question 12
Which of the following is considered a universal precaution?
A. Wearing gloves with every patient
B. Using sterile instruments only for surgery
C. Disinfecting floors daily
D. Isolating all patients
Rationale: Universal precautions require treating all blood and body fluids as potentially
infectious, including wearing gloves during patient contact.
Question 13
Which of the following is the normal range for adult blood pressure?
A. 80/40 mmHg
B. 100/60 mmHg
C. 120/80 mmHg
D. 140/90 mmHg
Rationale: The average normal adult blood pressure is 120/80 mmHg, though ranges
may vary slightly.
Question 14
Which of the following is the correct order of draw for blood collection?
A. Red, Blue, Green, Lavender
B. Blue, Red, Green, Lavender
C. Lavender, Green, Blue, Red
D. Green, Lavender, Blue, Red
Rationale: The order of draw prevents cross-contamination of additives: Blue
(coagulation), Red (serum), Green (heparin), Lavender (EDTA).
Question 15
Which of the following is the most accurate method of patient identification?
A. Asking the patient’s name
B. Checking the patient’s wristband
