A patient presents with a regular narrow-complex tachycardia at 160 bpm and is hemodynamically stable. Vagal maneuvers failed. What is the next appropriate treatment?
Answer: Adenosine 6 mg rapid IV push followed by 20 mL saline flush
Adenosine 6 mg rapid IV push is the first-line drug for stable SVT after failed vagal maneuvers, as it transiently blocks AV node conduction.
During post-resuscitation care after ROSC, what is the target oxygen saturation range to avoid hyperoxia?
Answer: 94-99%
Post-ROSC care targets SpO2 of 94-99% to prevent reperfusion injury from hyperoxia while ensuring adequate oxygenation.
A 45-year-old female presents with syncope and the following ECG findings: prolonged QT interval and a twisting pattern around the baseline. What rhythm is this?
Answer: Torsades de Pointes
Torsades de Pointes is a polymorphic VT characterized by QRS complexes that twist around the isoelectric baseline, associated with a prolonged QT interval.
For a witnessed, monitored VF arrest in a patient with an implanted pacemaker, how should defibrillator pads be positioned?
Answer: At least 8 cm away from the pacemaker generator
Defibrillator pads should be placed at least 8 cm from an implanted device to prevent damage to the pacemaker and ensure effective current delivery.
What is the recommended IV dose of epinephrine during cardiac arrest in an adult patient?
Answer: 1 mg every 3-5 minutes
The standard ACLS dose of epinephrine in adult cardiac arrest is 1 mg IV/IO every 3-5 minutes.
A patient presents with third-degree (complete) heart block. Which of the following best describes this rhythm?
Answer: Complete dissociation between atrial and ventricular activity with no relationship between P waves and QRS complexes
Third-degree heart block features complete AV dissociation where atria and ventricles beat independently with no relationship between P waves and QRS complexes.
A patient in cardiac arrest is receiving high-quality CPR. The ETCO2 remains below 10 mmHg despite two rescuers alternating compressions. What does this most likely indicate?
Answer: Inadequate compression depth or rate
Persistently low ETCO2 during CPR despite proper technique suggests poor cardiac output from inadequate compression depth or rate.
