NREMT Emergency Medical Technician (EMT) Cognitive ExamAirway, Respiration & VentilationMedium
A 28-year-old female is found unconscious after a suspected opioid overdose. Her respirations are slow and shallow at 6 breaths per minute. Her pulse is 50 bpm and strong. What is the most important initial intervention for this patient?
- AInitiate positive pressure ventilation with a bag-valve mask.
- BApply high-flow oxygen via non-rebreather mask.
- CAdminister naloxone intramuscularly.
- DPerform a rapid trauma assessment.
Show answer & explanationAnswer & explanation
Correct answer: A. Initiate positive pressure ventilation with a bag-valve mask.
Despite the likely cause being opioid overdose and the availability of naloxone, the immediate life threat is severe respiratory depression (6 breaths/min). Ensuring adequate ventilation with a bag-valve mask takes precedence over administering naloxone, as oxygenation and ventilation are critical for survival.
Why the other options are wrong
- B. High-flow oxygen alone will not overcome inadequate ventilatory effort; the patient needs assistance with breathing.
- C. Naloxone is important, but addressing inadequate breathing is the immediate priority.
- D. While a rapid trauma assessment might be part of a full assessment, it is not the most important immediate intervention for this life-threatening respiratory depression.
Respiratory Depression
A condition characterized by a reduced rate and/or depth of breathing, leading to inadequate oxygenation and/or carbon dioxide elimination.
- Commonly caused by opioids, sedatives, or central nervous system depressants.
- Can lead to hypoxia, hypercapnia, and respiratory arrest.
- Requires immediate ventilatory support.
Memory trick: Breathe first, then reverse the poison.
