What is the difference between body substance isolation (BSI) and PPE selection? - Answers BSI is a
universal approach; PPE selection is risk-based and tailored to the specific exposure.
What is the most common cause of EMS provider injury? - Answers Lifting and moving patients
improperly.
Why is fatigue considered a workforce safety issue? - Answers It impairs judgment, reaction time, and
increases error rates.
Why can pulmonary contusions worsen hours after trauma? - Answers Inflammatory edema
increases over time, impairing gas exchange.
Why can CPAP worsen hypotension in trauma patients? - Answers Increased intrathoracic pressure
reduces venous return (↓ preload).
Why is hypoxia often the earliest sign of chest trauma? - Answers Ventilation/perfusion mismatch
occurs before hemodynamic collapse.
Why should you avoid anchoring bias in patients with multiple complaints? - Answers It can cause
you to miss a life-threatening condition masked by a less serious complaint.
What assessment tool helps prioritize complex patients? - Answers Primary assessment with
continuous reassessment.
Why do elderly patients decompensate faster? - Answers Reduced physiologic reserve and impaired
compensatory mechanisms.
Why should altered mental status not be assumed baseline in dementia? - Answers Acute changes
often indicate hypoxia, hypoglycemia, infection, or stroke.
Why must consent be carefully assessed in special needs patients? - Answers Capacity is task-specific
and may fluctuate.
Why can pulse oximetry appear normal in carbon monoxide poisoning? - Answers The device cannot
differentiate oxyhemoglobin from carboxyhemoglobin.
Why is SpO₂ a late indicator of respiratory failure? - Answers Oxygen saturation can remain normal
despite rising CO₂ levels.
What does a poor waveform indicate? - Answers Inadequate perfusion or motion artifact.
Why are head, neck, and torso injuries concerning in abuse cases? - Answers They are inconsistent
with accidental injury patterns.
Why should documentation avoid assumptions? - Answers EMS reports are legal documents and may
be used in court.
Why is selective spinal motion restriction preferred over routine immobilization? - Answers Full
immobilization increases aspiration risk, pressure injuries, and respiratory compromise.
What is the most important factor in deciding SMR? - Answers Patient reliability and neurologic
status.
Why should suctioning be minimized in hypoxic patients? - Answers It worsens hypoxia by removing
oxygen from the airway.
What complication can deep suctioning cause? - Answers Bradycardia via vagal stimulation.
What differentiates visceral from somatic pain? - Answers Visceral pain is diffuse and poorly localized;
somatic pain is sharp and localized.
Why is ischemic pain often described as pressure? - Answers Anaerobic metabolism stimulates
nociceptors differently than inflammatory pain.
Why is pulmonary edema life-threatening? - Answers Fluid in alveoli prevents oxygen diffusion.
Why is the primary assessment dynamic? - Answers Patient conditions change rapidly and require
constant reassessment.
Why is 'normal' vital signs misleading in early shock? - Answers Compensatory mechanisms maintain
BP until decompensation.
Why is a decreasing GCS more concerning than a single low score? - Answers It indicates worsening
neurological function.
Why is motor response the most predictive GCS component? - Answers It reflects cortical and
brainstem function.
Why is OPQRST less reliable in ischemic or altered patients? - Answers Pain perception and
communication may be impaired.
Why should secondary assessment never delay transport? - Answers Time-sensitive conditions
worsen with prolonged scene time.
