(EMSU) Final LATEST 2026-2027 120
QUESTIONS AND 100% Verified
ANSWERS GRADED A+
1. Your primary concern when arriving at the scene of a
motor vehicle crash is:
A. Assessing the patient's airway
B. Surveying the area for hazards
C. Calling for additional resources
D. Immobilizing the patient's spine
Answer: B. Surveying the area for hazards
Rationale: Scene safety is the first and most critical priority in any
EMS response. You must ensure the environment is safe for
yourself, your partner, and the patient before initiating any patient
care. Hazards can include traffic, fire, downed power lines, or
violence.
2. Who is legally responsible for the clinical and patient care
aspects of an EMS system?
A. The Shift Supervisor
B. The Medical Director
C. The State EMS Board
D. The Lead Paramedic
Answer: B. The Medical Director
Rationale: The Medical Director is the physician who provides
medical oversight, authorizes protocols, and bears the ultimate
,legal responsibility for all clinical care provided by the EMS
system.
3. A conscious, competent adult patient refuses care and
transport. What is the MOST appropriate action?
A. Transport the patient against their will.
B. Contact law enforcement for assistance.
C. Explain the refusal process to the patient and document.
D. Allow the family to make the decision.
Answer: C. Explain the refusal process to the patient and
document.
Rationale: A conscious, competent adult has the legal right to
refuse care. The provider must assess their capacity, explain the
risks of refusal, offer alternatives, and thoroughly document the
entire process and the patient's informed decision.
Airway Management & Respiratory Care
This section covers the critical skills and knowledge for managing
a patient's airway and breathing.
4. When inserting an oropharyngeal airway (OPA) in an adult
patient, how should the airway be oriented initially?
A. With the tip pointing down towards the tongue.
B. With the tip pointing sideways.
C. With the tip pointing up towards the roof of the mouth.
D. Directly into the throat without rotation.
Answer: C. With the tip pointing up towards the roof of the
mouth.
,Rationale: An OPA is initially inserted upside down (with the tip
pointing toward the roof of the mouth) to avoid pushing the
tongue back into the pharynx. Once the tip reaches the soft
palate, it is rotated 180 degrees into its correct position.
5. When performing rescue breathing with a bag-valve-mask
(BVM) on an apneic adult patient with a pulse, what is the
appropriate rate of ventilation?
A. 1 breath every 2 to 3 seconds.
B. 1 breath every 5 to 6 seconds.
C. 1 breath every 8 to 10 seconds.
D. 2 breaths every 15 seconds.
Answer: B. 1 breath every 5 to 6 seconds.
Rationale: This rate delivers approximately 10 to 12 breaths per
minute, which is the standard AHA guideline for adult rescue
breathing for a patient with a pulse.
6. What does the presence of high-pitched stridor upon
inspiration typically indicate?
A. Secretions in the lower bronchioles.
B. Severe bronchoconstriction in the lungs.
C. Fluid accumulation in the alveoli.
D. A partial upper airway obstruction.
Answer: D. A partial upper airway obstruction.
Rationale: Stridor is a high-pitched, crowing sound heard on
inspiration that indicates a partial obstruction in the upper airway
(larynx or trachea), often due to swelling or a foreign body.
, Medical & Cardiac Emergencies
These questions address the identification and initial management
of common medical emergencies.
7. What does the clinical acronym ROSC stand for during a
resuscitation attempt?
A. Rapid Oxygenation of Systemic Cells.
B. Return of Spontaneous Circulation.
C. Resuscitation Ordered by Senior Clinician.
D. Rate of Survival for Cardiac Patients.
Answer: B. Return of Spontaneous Circulation.
Rationale: ROSC is the critical endpoint of CPR, defined as the
return of a pulse and the resumption of organized cardiac
mechanical activity.
8. What is the correct recommended depth of chest
compressions for an adult patient?
A. 1 to 1.5 inches.
B. At least 2 inches but no more than 2.4 inches.
C. Exactly 3 inches.
D. One-half the depth of the torso.
Answer: B. At least 2 inches but no more than 2.4 inches.
Rationale: Current AHA guidelines recommend compressing the
chest at least 2 inches (5 cm) for an adult, but not more than 2.4
inches (6 cm). This depth is effective for generating blood flow
while minimizing the risk of injury.
