Which intraosseous insertion site is preferred in adults when rapid IO access is needed?
Answer: Proximal tibia
The proximal tibia is the preferred IO site in adults due to its accessibility, flat surface, and thick cortex that accommodates standard IO needles reliably.
A patient is being ventilated via ETT and peak airway pressures have significantly increased. The first step is to:
Answer: Suction the ETT
Rising peak airway pressures should first prompt suctioning to rule out mucus plug or secretion obstruction before other interventions.
When using a mechanical CPR device (e.g., LUCAS or AutoPulse), which situation is an absolute contraindication?
Answer: Pediatric patients under age-based size limits
Mechanical CPR devices are contraindicated in pediatric patients who fall outside the device's minimum size specifications, as the force can cause severe internal injuries.
For synchronized cardioversion of unstable atrial fibrillation, the recommended initial energy setting using a biphasic defibrillator is:
Answer: 100-200 J
Biphasic cardioversion for atrial fibrillation typically begins at 100-200 J, as lower energies reduce myocardial injury while maintaining adequate conversion rates.
A patient with an implanted pacemaker goes into pulseless ventricular tachycardia. The paramedic should:
Answer: Defibrillate but place pads at least 8 cm away from the device
Defibrillation should not be withheld in pulseless VT; pads should be placed at least 8 cm from the pacemaker generator to avoid device damage while still delivering effective therapy.
Which pulse oximetry condition can give a falsely elevated SpO2 reading?
Answer: Carbon monoxide poisoning
Carbon monoxide binds hemoglobin similarly to oxygen and is read as oxyhemoglobin by standard pulse oximeters, causing falsely elevated SpO2 despite severe hypoxia.
Which intervention is indicated if a patient's ETCO2 is consistently above 60 mmHg during BVM ventilation?
Answer: Increase ventilation rate to eliminate excess CO2
ETCO2 above 60 mmHg indicates hypoventilation and CO2 retention; increasing ventilation rate will lower CO2 levels toward the normal range of 35-45 mmHg.
