Question 1
A 45-year-old male patient presents with sudden onset of severe chest pain and
shortness of breath. The patient is diaphoretic and anxious. Which action should
the EMT take FIRST?
A. Administer aspirin 324 mg
B. Obtain a 12-lead ECG
C. Apply oxygen and assess airway
D. Administer nitroglycerin
Correct Answer: C
Rationale: Applying oxygen and assessing airway is the FIRST action because
airway and breathing are the priority in the ABCs (Airway, Breathing,
Circulation). Ensuring adequate oxygenation and a patent airway is critical before
any other interventions. Aspirin and nitroglycerin are important for cardiac patients
but come after airway/breathing assessment. A 12-lead ECG is necessary but not
the first priority. Always follow ABCs in emergency situations.
Question 2
Which term describes the process of exchanging oxygen and carbon dioxide at the
cellular level?
A. Ventilation
B. Respiration
C. Perfusion
D. Inhalation
Correct Answer: B
Rationale: Respiration (also called cellular respiration) is the process of
exchanging oxygen and carbon dioxide at the cellular level between blood and
tissues. Ventilation is the mechanical process of moving air in and out of the
lungs. Perfusion is blood flow through tissues. Inhalation is breathing in.
Understanding these terms is essential for EMTs to assess respiratory function
accurately.
Question 3
pg. 2
,3
A 6-year-old child has a respiratory rate of 28 breaths/min. Is this within normal
limits for this age?
A. Yes, normal range is 20-30 breaths/min
B. No, normal range is 12-20 breaths/min
C. Yes, normal range is 30-50 breaths/min
D. No, normal range is 18-24 breaths/min
Correct Answer: A
Rationale: For a 6-year-old child, the normal respiratory rate is 20-30
breaths/min. A rate of 28 breaths/min is within normal limits. Adult normal range
is 12-20 (Option B). Infant/toddler range is 30-50 (Option C). Option D is not
accurate for this age group. EMTs must know age-specific normal parameters for
pediatrics.
Question 4
Which position is MOST appropriate for a patient with suspected spinal injury?
A. Supine on a long spine board
B. Sitting up
C. Fowler's position
D. Prone position
Correct Answer: A
Rationale: Supine on a long spine board is MOST appropriate for a patient
with suspected spinal injury to maintain spinal alignment and prevent movement.
The patient should be fully immobilized with a cervical collar, head blocks, and
straps. Sitting up, Fowler's (semi-sitting), and prone (lying on stomach) positions
could worsen spinal injury. Full spinal immobilization is critical until injury is
ruled out.
Question 5
A patient has a blood glucose level of 45 mg/dL. Which condition does this
indicate?
A. Hyperglycemia
B. Hypoglycemia
pg. 3
, 4
C. Normal glucose level
D. Euglycemia
Correct Answer: B
Rationale: A blood glucose level of 45 mg/dL indicates hypoglycemia (low blood
sugar). Normal range is 70-110 mg/dL. Hyperglycemia is high blood sugar (>110
mg/dL). Euglycemia is normal glucose. Hypoglycemia requires immediate
treatment with oral glucose (if conscious) or IV dextrose/glucagon (if unconscious)
to prevent brain damage and seizures.
Question 6
Which artery is BEST for assessing the pulse in an adult patient?
A. Radial artery
B. Carotid artery
C. Brachial artery
D. Femoral artery
Correct Answer: A
Rationale: The radial artery (at the wrist) is BEST for assessing pulse in adult
patients who are stable. It's easily accessible and non-invasive. Carotid artery is
used for unconscious patients or CPR. Brachial artery is preferred for
infants/children. Femoral artery is used in trauma when other pulses are not
palpable. EMTs should assess radial pulse first in stable adults.
Question 7
A patient is experiencing anaphylaxis. Which medication is the FIRST-line
treatment?
A. Diphenhydramine (Benadryl)
B. Epinephrine
C. Albuterol
D. Corticosteroids
Correct Answer: B
Rationale: Epinephrine is the FIRST-line treatment for anaphylaxis (severe
allergic reaction). It rapidly reverses airway swelling, bronchospasm, and
