Which of the following is the reversible cause of PEA represented by the '5 H's and 5 T's' mnemonic?
Answer: Hypovolemia
Hypovolemia is one of the 5 H's (Hypovolemia, Hypoxia, H+ acidosis, Hypo/Hyperkalemia, Hypothermia) and is a treatable cause of PEA.
Beck's Triad — muffled heart sounds, jugular vein distension, and hypotension — is associated with which condition?
Answer: Cardiac tamponade
Beck's Triad describes cardiac tamponade, where fluid in the pericardial sac compresses the heart and impairs cardiac output.
What is the initial adult dose of amiodarone for stable wide-complex tachycardia (VT with pulse)?
Answer: 150 mg IV over 10 minutes
For stable VT, amiodarone is administered as 150 mg IV over 10 minutes, followed by an infusion if needed.
A patient presents with sudden pleuritic chest pain, tachycardia, and hypoxia after a long flight. What diagnosis should be prioritized?
Answer: Pulmonary embolism
Sudden pleuritic chest pain, dyspnea, tachycardia, and recent immobility (long flight) are classic signs of pulmonary embolism.
Which intervention is the definitive prehospital treatment for a symptomatic bradycardia unresponsive to atropine?
Answer: Transcutaneous pacing (TCP)
Transcutaneous pacing is the definitive intervention for symptomatic bradycardia that does not respond to atropine.
What is the correct initial dose of adenosine for stable supraventricular tachycardia (SVT) in adults?
Answer: 6 mg IV rapid push followed by saline flush
Adenosine 6 mg IV is given as a rapid push followed immediately by a 20 mL normal saline flush to ensure delivery before the drug is metabolized.
