Ambulance collision: Stop, assess all injured (your patient, crew, other vehicle), request additional units if needed, notify dispatch, document everything. Don’t leave the scene unmanaged.
-
Question 9 of 50
9. Question
9. A family member asks you not to tell their elderly parent about a serious diagnosis you discovered during assessment. What should you do?
CorrectIncorrectHint
Competent adults have the right to know about their condition. Be honest if asked. Family can’t override patient autonomy. Complex discussions are often best at the hospital.
-
Question 10 of 50
10. Question
10. What is the primary purpose of a prehospital care report (PCR)?
CorrectIncorrectHint
PCR = Patient Care Record. Document for the next provider: What you found, what you did, how the patient responded. Care continuity comes first.
-
Question 11 of 50
11. Question
11. During an MCI, you encounter a patient with a partial amputation of the foot with controlled bleeding who can walk. Using START triage, how should this patient be categorized?
CorrectIncorrectHint
START triage first question: “Can you walk?” Walking patients = Minimal (Green) and are directed to a collection point. Don’t reassess them until non-walking patients are triaged.
-
Question 12 of 50
12. Question
12. You arrive at a scene with multiple agencies responding (fire, police, EMS). Who is responsible for coordinating all agencies during the incident?
CorrectIncorrectHint

HIPAA covered entities: Healthcare providers who bill electronically, health plans, healthcare clearinghouses. EMS agencies = covered entities. Protect patient information.
-
Question 14 of 50
14. Question
14. During your patient assessment, you make an error in your documentation. What is the correct way to handle this?
CorrectIncorrectHint
Documentation errors: Single line through, initial, date, correct entry. Never erase, white-out, or destroy records. Original error must remain legible.
-
Question 15 of 50
15. Question
15. You respond to a factory where workers are reporting difficulty breathing and nausea. You notice a yellow placard with a number 6 on a storage container. What does this indicate?
CorrectIncorrectHint
Placard 6 = Poison/toxic. White background = poison or infectious. Workers with breathing difficulty + toxic placard = HazMat call. Stage safely upwind.
-
Question 16 of 50
16. Question
16. When should you use plain English instead of radio codes during communications?
CorrectIncorrectHint
NIMS = plain English. No 10-codes during incidents. “I have one patient with chest pain” not “I have a 10-50 with 10-12.” Different codes = confusion.
-
Question 17 of 50
17. Question
17. Which of the following is the MOST effective method for preventing the spread of bloodborne pathogens?
CorrectIncorrectHint
Hand hygiene = #1 infection prevention. Wash before and after every patient. Gloves don’t replace hand washing. 20 seconds with soap and water, or alcohol-based sanitizer when soap unavailable.
-
Question 18 of 50
18. Question
18. What is the purpose of the “buffer zone” when positioning an ambulance at a scene?

-
Question 20 of 50
20. Question
20. Your agency is reviewing response times for cardiac arrest calls. This is an example of what type of quality improvement activity?
CorrectIncorrectHint
QI types: System analysis (response times, equipment), Peer review (provider performance), Protocol review (treatment effectiveness). All are for improvement, not punishment.
-
Question 21 of 50
21. Question
21. Which component of a patient care report (PCR) documents the patient’s subjective statements, chief complaint, and history in their own words?

-
Question 25 of 50
25. Question
25. An EMT realizes after submitting a patient care report that she accidentally documented “nitroglycerin administered” when the patient actually received aspirin. What is the correct procedure for correcting this documentation error?
CorrectIncorrectHint
Correct errors transparently: single line through, initial, date, and write the right thing. Never erase, white-out, or destroy documentation.
-
Question 26 of 50
26. Question
26. You respond to a motor vehicle crash where a 45-year-old female was the driver. She has a laceration on her forehead and appears dazed but refuses treatment, stating she is fine and just wants to go home. She knows her name, the date, and where she is. What is your MOST appropriate legal action?
CorrectIncorrectHint
Competent adults can refuse care. Your job: explain risks, attempt to persuade, get signature, document thoroughly. Never force treatment on a capable patient.
-
Question 27 of 50
27. Question
27. An EMT is completing a PCR for a patient with chest pain who was transported to the emergency department. Which entry demonstrates proper objective documentation?
CorrectIncorrectHint
Document what you see, hear, measure, and are told – not what you assume, judge, or diagnose. Facts, not opinions.
-
Question 28 of 50
28. Question
28. You are treating an unresponsive 72-year-old male found by family members at home. Family states he has a history of diabetes, hypertension, and “some kind of heart problem.” They do not know his medications. His blood glucose is 42 mg/dL. After administering oral glucose, his mental status improves, and he becomes oriented. When documenting this call, which information is MOST critical to include in your patient care report?

What is your BEST course of action regarding disclosure and documentation?
CorrectIncorrectHint
Minor patients may have confidentiality rights for pregnancy, STIs, and substance abuse in many states. Know your local laws and respect patient privacy within legal bounds.
-
Question 30 of 50
30. Question
30. An EMT responds to a call where a patient dies despite resuscitation efforts. The death appears suspicious, with injuries inconsistent with the reported mechanism. Law enforcement is on scene. Which documentation approach is MOST appropriate for this situation?
CorrectIncorrectHint

Justice = treating ALL patients fairly, even the “frequent flyers” who frustrate you. Your feelings don’t change their rights.
-
Question 36 of 50
36. Question
36. During a cardiac arrest resuscitation, an EMT makes an error in medication dosing. The error is caught immediately and corrected, but the EMT is embarrassed. When completing the patient care report, the EMT considers omitting the error to avoid scrutiny. Which action demonstrates the HIGHEST level of professionalism?

You can’t lie for patients, but you can advocate. Be honest about your obligations while minimizing unnecessary disclosure.
-
Question 40 of 50
40. Question
40. An EMT with 10 years of experience is paired with a new EMT who graduated last month. During a cardiac arrest, the experienced EMT notices the new EMT performing CPR compressions that are too shallow. The experienced EMT is frustrated and wants to take over. Considering professional development, team dynamics, and patient care, what is the MOST appropriate approach?
CorrectIncorrectHint
Real-time coaching + patient safety = professional mentorship. Correct kindly, teach constantly, take over if needed.
-
Question 41 of 50
41. Question
41. Which action is the FIRST priority when arriving at the scene of a motor vehicle collision?

-
Question 44 of 50
44. Question
44. During primary assessment of an unresponsive adult patient, you observe that the patient has gurgling respirations. What is your immediate priority action?
CorrectIncorrectHint
Gurgling = fluid in the airway. Suction immediately before the patient aspirates. Clear the path before anything else.
-
Question 45 of 50
45. Question
45. You respond to a single-vehicle collision on a rural highway at night. As you approach, you observe downed power lines across the roadway near the vehicle. The driver appears to be moving inside the car. What is your most appropriate initial action?

Downed power lines = stage 35+ feet away (one pole span), call utility company, tell patient to stay in vehicle if lines touch it. Never approach until cleared.
-
Question 46 of 50
46. Question
46. You are assessing a 54-year-old male with chest pain. He opens his eyes when you speak to him, knows his name, knows he is at home, but is unsure of the day or date. How would you document his mental status?
CorrectIncorrectHint
Document mental status as A+O×3 (all three), A+O×2 (two of three), A+O×1 (one of three), or A+O×0 (disoriented to all). Time is the most commonly lost orientation.
-
Question 47 of 50
47. Question
47. You respond to a residence for a 72-year-old female with difficulty breathing. Upon entering the room, you observe the patient sitting upright in a tripod position, using accessory muscles, with audible wheezing. Her skin is pale and diaphoretic. What does your general impression tell you about this patient’s status?
CorrectIncorrectHint
Tripod position + accessory muscles + diaphoresis = severe respiratory distress. This patient is working as hard as they can to breathe and needs immediate help.
-
Question 48 of 50
48. Question
48. You respond to a motor vehicle collision involving a compact car that struck a utility pole at moderate speed. The driver was unrestrained, the steering wheel is bent, and the windshield is starred on the driver’s side. Based on this mechanism, which injuries should you anticipate during your assessment?
CorrectIncorrectHint
Bent steering wheel + starred windshield = up-and-over mechanism. Anticipate: cervical spine, chest wall, cardiac, and abdominal injuries. This is multi-system trauma.
-
Question 49 of 50
49. Question
49. You are assessing a 34-year-old female who was found unresponsive by her roommate. Her respiratory rate is 6 breaths per minute with shallow tidal volume, her pupils are pinpoint, and her skin is pale. The roommate states the patient has a history of chronic back pain. Which statement BEST explains the pathophysiology connecting these findings?
CorrectIncorrectHint
Pinpoint pupils + respiratory depression + altered mental status = opioid overdose classic triad. Check for opioid patches, pills, or drug paraphernalia; prepare for naloxone administration.
-
Question 50 of 50
50. Question
50. You respond to an industrial warehouse for an unresponsive worker. Upon arrival, you observe an overturned chemical drum with a diamond-shaped placard showing the number 3 in a red quadrant. A strong chemical odor is present, and you notice a visible vapor near the floor. Several employees are attempting to drag the patient toward the exit. What is your MOST appropriate action?
