In a patient with suspected tension pneumothorax causing cardiac arrest, the immediate intervention is:
Answer: Needle decompression at the 2nd intercostal space, midclavicular line
Tension pneumothorax causing arrest requires immediate needle decompression without imaging delay to relieve life-threatening intrathoracic pressure.
Which ECG finding is pathognomonic for hyperkalemia causing cardiac emergency?
Answer: Peaked T waves progressing to sine wave pattern
Severe hyperkalemia produces peaked T waves → widened QRS → sine wave morphology → asystole if untreated.
For a patient in pulseless VT, after the first defibrillation shock, compressions should resume for how long before reassessing the rhythm?
Answer: 2 minutes
After each defibrillation attempt, CPR should continue for 2 minutes before pausing to check the rhythm to maximize coronary perfusion pressure.
A cardiovascular specialist is managing a patient with type A aortic dissection. The immediate priority is:
Answer: Emergent surgical consultation for repair
Type A aortic dissection (involving the ascending aorta) carries high mortality and requires emergent surgical repair.
Which drug should be administered for torsades de pointes (polymorphic VT associated with long QT)?
Answer: Magnesium sulfate 1–2g IV
IV magnesium sulfate (1–2g) is the treatment of choice for torsades de pointes, even in patients with normal serum magnesium levels.
During cardiac catheterization, a patient develops a coronary artery perforation with pericardial effusion. First-line management is:
Answer: Balloon inflation at perforation site for tamponade
Balloon inflation over the perforation site to seal the vessel is the immediate catheterization-lab response to coronary perforation before surgical backup.
A patient in third-degree heart block with hemodynamic compromise requires immediate treatment. What is the first intervention?
Answer: Transcutaneous pacing
Transcutaneous pacing is the fastest non-invasive way to restore heart rate in symptomatic complete heart block while preparing for transvenous pacing.
