47. Frage
A 67-year-old patient is unresponsive, and an EMT checks for a pulse prior to applying an AED. Which of the following screenable rhythms, ventricular fibrillation or ventricular tachycardia, if either, may still produce a pulse in this patient?
Antwort: D
Begründung:
The correct answer is B. Ventricular tachycardia only.
Key Concept: Shockable Rhythms and Pulse Presence
The two primary shockable rhythms are:
* Ventricular fibrillation (VF)
* Ventricular tachycardia (VT)
Ventricular Fibrillation (VF):
* Chaotic, disorganized electrical activity
* No effective cardiac output
* Always pulseless
NREMT-aligned reference:
* "Ventricular fibrillation results in no pulse due to ineffective quivering of the ventricles." Ventricular Tachycardia (VT):
* Rapid, organized ventricular rhythm
* May be:
* Pulseless VT (cardiac arrest)
* Perfusing VT (with a pulse)
NREMT-aligned reference:
* "Ventricular tachycardia may present with or without a pulse."
Why B is correct:
* Only ventricular tachycardia can sometimes produce a pulse
* VF never produces a pulse
Why the other options are incorrect:
* A. VF only # Incorrect; VF is always pulseless
* C. Both # Incorrect; VF cannot produce a pulse
* D. Neither # Incorrect; VT can produce a pulse
Exact Extracts (NREMT/AHA-aligned references):
* "Shockable rhythms include ventricular fibrillation and pulseless ventricular tachycardia."
* "Ventricular tachycardia may be with or without a pulse."
* "Ventricular fibrillation produces no cardiac output."
Clinical Priority Summary:
Among shockable rhythms, only ventricular tachycardia can still produce a pulse, making B the correct answer.

48. Frage
The crew is requested to respond by law enforcement to a riot scene in a large downtown area. Upon arrival, the EMT notices the police are in full riot gear, with multiple persons lying on the ground under arrest. There is a strong odor of chemicals in the air. What actions should the EMT prioritize during the scene survey?
Select the two answer options that are correct.
Antwort: A,C
Begründung:
Comprehensive and Detailed Explanation (Based on NREMT standards):
This scenario strongly suggests a hazardous environment involving chemical crowd-control agents such as tear gas or pepper spray. During the scene survey, NREMT prioritizes scene safety, hazard recognition, and incident size-up before any patient contact.
Option D (Determine the control agent being used) is correct because identifying the chemical agent helps determine the level of risk, appropriate personal protective equipment, and whether EMS can safely operate in the area.
Option E (Identify the number of patients) is correct because determining the number of patients is essential for assessing the scope of the incident and requesting additional resources if needed.
Option A is incorrect because removing restraints is not part of the initial scene survey and must be coordinated with law enforcement.
Option B is incorrect because patient decontamination occurs only after scene safety is ensured.
Option C is not a priority until hazards are identified and the scene is safe.
NREMT teaches that EMTs must never compromise their own safety and must fully assess hazards before providing care.
49. Frage
Calling your medical director for orders to assist with administration of an additional dose of nitroglycerin is an example of
Antwort: D
Begründung:
This situation describes contacting the medical director directly for patient-specific instructions , which is the definition of on-line medical direction . In national EMS education guidance used by NREMT-aligned programs, EMTs must be able to consult on-line medical direction when needed.
Why B is correct:
When an EMT calls for permission or orders to give an additional dose of nitroglycerin , that is real-time communication with physician oversight. This is on-line medical direction rather than a standing order. The EMS curriculum also explains that medication administration such as nitroglycerin may occur with medical direction approval .
Why the other options are wrong:
A). standard operating protocols - these are standing rules or preapproved procedures followed without calling for a new patient-specific order.
C). evidence-based medicine - this means care guided by research and best evidence, not a phone/radio order from medical control.
D). continuous quality improvement - this refers to reviewing and improving system performance, not obtaining treatment orders during active patient care.
50. Frage
A person grabs your arm during an argument. This is considered
Antwort: A
Begründung:
The correct answer is C. Battery.
This question tests knowledge of legal definitions relevant to EMS providers, particularly distinguishing between assault and battery.
Battery is defined as unlawful physical contact with another person without consent.
In this scenario, the act of grabbing your arm constitutes intentional physical contact, which meets the definition of battery.
According to NREMT-aligned EMS legal principles:
"Battery is the unlawful touching of another person without consent."
Why the other options are incorrect:
A). Harassment:Typically involves repeated or persistent unwanted behavior, not necessarily physical contact.
B). Assault:Defined as threatening or attempting to cause harm, creating fear of imminent harm-without actual physical contact.
D). False imprisonment:Involves restricting a person's freedom of movement without legal authority, not simply grabbing an arm.
Key NREMT Distinction:
Assault = threat of harm
Battery = actual physical contact
Exact Extracts:
"Assault is placing a person in fear of immediate harm."
"Battery is the unlawful touching of a patient without consent."

51. Frage
A 78-year-old female tripped and fell while walking. Her left leg is rotated externally and shorter than her right leg. You should suspect
Antwort: C
Begründung:
An externally rotated, shortened leg is a classic sign of a proximal femur fracture, specifically a femoral neck or intertrochanteric fracture, commonly seen in elderly fall patients. This presentation reflects muscle pull and fracture displacement.
* Posterior hip dislocations cause internal rotation.
* Pelvic fractures may cause instability but not specific leg rotation/shortening.
* Colles ' fracture is a distal radius (wrist) injury, unrelated to leg trauma.
