What is the correct compression-to-ventilation ratio for a single rescuer performing CPR on an adult?
Answer: 30:2
A single rescuer performing adult CPR uses a 30:2 ratio (30 compressions followed by 2 ventilations) to maximize perfusion time while providing oxygenation.
Which device is used to confirm and continuously monitor correct ETT placement during transport?
Answer: Capnography (ETCO2) monitor
Continuous waveform capnography is the gold standard for confirming and monitoring endotracheal tube placement throughout transport.
A patient with suspected cervical spine injury requires airway management. The preferred method is:
Answer: Video laryngoscopy with manual in-line stabilization
Video laryngoscopy combined with manual in-line cervical stabilization allows visualization for intubation while minimizing cervical spine movement.
Which rhythm requires immediate unsynchronized defibrillation?
Answer: Pulseless ventricular fibrillation
Pulseless ventricular fibrillation is a shockable rhythm requiring immediate unsynchronized defibrillation as it has no organized cardiac complex to synchronize to.
What is the purpose of the SAMPLE history mnemonic in patient assessment?
Answer: Gather systematic medical history (Signs/Symptoms, Allergies, Medications, Pertinent history, Last oral intake, Events)
SAMPLE provides a systematic framework to collect essential medical history: Signs/Symptoms, Allergies, Medications, Pertinent history, Last oral intake, and Events leading to the emergency.
A patient requires spinal motion restriction on a long backboard. After securing the torso, the head is immobilized:
Answer: Last, after torso and legs are secured
When applying a long backboard, the torso is secured first, then the legs, and finally the head, because securing the torso first prevents the patient from sliding and allows head blocks to hold securely.
Which prehospital intervention is indicated for a patient with signs of tension pneumothorax and impending cardiovascular collapse?
Answer: Needle decompression of the affected side
Needle decompression of the affected hemithorax is the immediate prehospital treatment to relieve the pressure buildup causing tension pneumothorax and cardiovascular collapse.
