A patient presents with a wide-complex tachycardia at 180 bpm. The patient is stable. The rhythm is regular. What is the first-line pharmacologic treatment if the rhythm is presumed SVT with aberrancy?
Answer: Adenosine 6 mg rapid IV push
Adenosine is the drug of choice for stable regular wide-complex tachycardia suspected to be SVT with aberrancy because it is safe and diagnostic.
During post-cardiac arrest care, what is the recommended target range for arterial oxygen saturation (SpO2)?
Answer: 94–99%
Post-ROSC oxygen should be titrated to an SpO2 of 94–99% to avoid both hypoxia and hyperoxia, which can worsen neurological outcomes.
A patient in PEA arrest has a HR of 60 on the monitor. The team suspects cardiac tamponade. Which H or T is this classified under?
Answer: Tamponade (cardiac)
Cardiac tamponade is one of the Ts in the H's and T's of reversible causes of PEA, requiring emergency pericardiocentesis.
When performing bag-mask ventilation during CPR with an advanced airway in place, what is the recommended ventilation rate for adults?
Answer: 1 breath every 6 seconds (10/min)
Once an advanced airway is placed, deliver 1 breath every 6 seconds (10 breaths/min) asynchronously with continuous chest compressions.
A patient develops polymorphic VT with a prolonged QTc interval. Which drug is the treatment of choice?
Answer: Magnesium sulfate 1–2 g IV
Torsades de pointes (polymorphic VT with prolonged QTc) is treated with magnesium sulfate 1–2 g IV to stabilize the myocardium.
Which of the following best describes the role of lidocaine in current ACLS cardiac arrest algorithms?
Answer: Alternative antiarrhythmic when amiodarone is unavailable
Lidocaine is an acceptable alternative to amiodarone for shock-refractory VF/pVT when amiodarone is not available.
A patient has ROSC after 15 minutes of CPR. She remains comatose with no purposeful movement to pain. Which post-resuscitation intervention has the strongest evidence for improving neurological outcomes?
Answer: Targeted temperature management (TTM) between 32–36°C
Targeted temperature management (TTM) at 32–36°C for at least 24 hours is recommended for comatose survivors of cardiac arrest to improve neurological outcomes.
