A conscious patient presents with urticaria, wheezing, hypotension, and a history of bee sting 10 minutes ago. What is the first-line treatment?
Answer: Epinephrine 0.3 mg IM to the lateral thigh
Epinephrine IM is the first-line and potentially life-saving treatment for anaphylaxis, addressing bronchoconstriction and vasodilation simultaneously.
During transport, a patient with a suspected pulmonary embolism deteriorates with decreasing BP and SpO2. Which additional intervention is most appropriate?
Answer: Cautious fluid resuscitation and rapid transport to ED
Massive PE management prehospital is supportive with cautious fluids and rapid transport; aggressive fluids can worsen right heart strain.
Which finding on a 12-lead ECG is most consistent with a right ventricular infarction?
Answer: ST elevation in leads II, III, and aVF with ST elevation in V4R
RV infarction typically accompanies inferior STEMI and is confirmed by ST elevation in right-sided lead V4R.
A seizing patient has been actively seizing for 8 minutes. IV access is unavailable. Which benzodiazepine route is most appropriate?
Answer: Rectal diazepam or intranasal/IM midazolam
Intranasal or IM midazolam and rectal diazepam are effective alternative routes when IV access is unavailable in status epilepticus.
A patient with end-stage renal disease presents with peaked T waves, wide QRS, and a serum potassium of 7.2 mEq/L. Which medication should be given first?
Answer: Calcium chloride or calcium gluconate
Calcium stabilizes the myocardial membrane immediately in hyperkalemia-induced cardiac toxicity, buying time for other interventions.
When transporting a patient in shock who requires both fluid resuscitation and vasopressors, which vasopressor is recommended as first-line for septic shock?
Answer: Norepinephrine
Norepinephrine is the first-line vasopressor for septic shock due to its reliable vasoconstrictive effect with minimal tachycardia.
A patient with suspected carbon monoxide poisoning has SpO2 of 99% on pulse oximetry. How should you interpret this reading?
Answer: Pulse oximetry is unreliable in CO poisoning as it cannot distinguish oxyhemoglobin from carboxyhemoglobin
Standard pulse oximetry cannot differentiate carboxyhemoglobin from oxyhemoglobin, giving falsely normal readings in CO poisoning.
