Sample Practice Questions (5)
1. Multiple patients from the same household present with headache, nausea, dizziness, and confusion. The pulse oximetry reads 99% on all patients. You should be MOST suspicious of:
- Carbon monoxide poisoning
- Food poisoning from a shared meal
- Viral gastroenteritis
- Natural gas leak causing methane inhalation
2. A patient with a known history of benzodiazepine dependence presents after ingesting an unknown quantity of lorazepam. He is somnolent with a respiratory rate of 8 and SpO2 of 88%. Which approach is MOST appropriate?
- Provide bag-valve-mask ventilation with supplemental oxygen and transport; avoid flumazenil due to seizure risk
- Administer flumazenil 0.2mg IV to reverse the benzodiazepine effects
- Administer naloxone 2mg IV in case opioids are also involved
- Administer activated charcoal 1g/kg orally to reduce absorption
3. A farmer is found in his field with copious oral secretions, miosis, bradycardia, muscle fasciculations, and respiratory distress. His coworker states he was spraying pesticide without proper PPE. What is the appropriate treatment for this patient?
- Atropine 2-4mg IV repeated every 5 minutes until secretions dry, followed by pralidoxime (2-PAM)
- Naloxone 2mg IV push repeated every 2-3 minutes
- Diphenhydramine 50mg IV for the allergic reaction
