The correct answer is B. Proximate causation.
To prove negligence in an EMS-related lawsuit, four elements must be established:
Duty to act
Breach of duty
Damages
Causation (proximate cause)
Proximate causation means that the EMT's actions (or inaction) directly caused the patient's injury or damages.
There must be a clear link between the breach of duty and the harm suffered.
A). Contributory neglect # Refers to patient contribution to injury, not a required element C). Malfeasance # Performing a wrongful act, but not one of the four legal elements D). Abandonment # A specific legal violation, not a required negligence element
"Negligence requires duty to act, breach of duty, damages, and causation."
"Proximate cause means the provider's actions directly resulted in injury."
"All four elements must be present to prove negligence."

NREMT guidelines clearly state that life-threatening danger overrides spinal motion restriction. This patient shows signs of a spinal cord injury (loss of movement and sensation), but they were previously trapped under a vehicle-an inherently unstable and dangerous environment.
Option A is correct because the clothes drag is an emergency move designed to remove a patient from immediate danger as quickly as possible. In emergency situations, speed and rescuer safety take priority over spinal immobilization.
Option B is incorrect because clothes drags do not minimize spinal movement.
Option C is incorrect because preparing and using a long backboard delays removal.
Option D is incorrect because spinal protection is secondary to immediate life threats.
NREMT emphasizes: "You cannot help the patient if you become injured."

If a choking patient becomes unresponsive, EMTs should:
Check for a pulse
Begin chest compressions if no pulse is foundChest compressions can help dislodge the object. After compressions, the airway should be opened and inspected. Back blows are not appropriate for unconscious patients.
Ventilation is attempted after clearing the airway or if no object is seen. Do not withhold compressions waiting for object removal.

The correct answer is C because in a third-trimester trauma patient with severe abdominal pain , vaginal bleeding , and clear signs of shock , the EMT should strongly suspect abruptio placentae . Official national EMS instructional guidance for pregnant trauma patients specifically lists separation of the placenta from the uterine wall as a key trauma concern, with abdominal pain and vaginal bleeding often present , and notes a high risk of fetal death . This matches the presentation in this question very closely. ( EMS.gov )

An epidural hematoma classically presents with a "lucid interval" - a brief period of regained consciousness following head trauma, followed by rapid deterioration. This is due to arterial bleeding, often from the middle meningeal artery, leading to increasing intracranial pressure.
Signs include:
High blood pressure
Decreasing respiratory rate
Altered LOC or unresponsiveness
Subdural hemorrhages are slower venous bleeds, common in elderly patients. Subarachnoid hemorrhage often presents with " worst headache of life. " Intracerebral bleeds are less commonly linked to lucid intervals.
