Medical Training Flashcards

A patient develops torsades de pointes. Which treatment is specifically indicated for this arrhythmia?

Answer: Magnesium sulfate 1–2 g IV

Magnesium sulfate is the treatment of choice for torsades de pointes, which is often associated with hypomagnesemia or QT prolongation.

During an ACLS scenario, the team leader calls for a 'pulse check.' How long should this check last?

Answer: No more than 10 seconds

Pulse checks should be no longer than 10 seconds to minimize interruptions to chest compressions.

Which IV/IO access site is preferred for medication administration during cardiac arrest when peripheral IV is not available?

Answer: Intraosseous (IO) access

IO access is preferred when IV access cannot be rapidly established, as it provides reliable vascular access during CPR.

What is the energy setting recommended for the first biphasic defibrillation shock in an adult with VF?

Answer: 120–200 J (per manufacturer)

For biphasic defibrillators, the recommended energy is 120–200 J based on manufacturer specifications for the first shock.

A patient has narrow-complex tachycardia at 170 bpm and is hemodynamically stable. Vagal maneuvers fail. What is the next ACLS step?

Answer: Adenosine 6 mg rapid IV push

Adenosine 6 mg rapid IV push is the first pharmacologic intervention for stable narrow-complex SVT after failed vagal maneuvers.

Which of the following best describes the role of high-quality CPR in ACLS?

Answer: It maintains perfusion pressure and improves likelihood of defibrillation success

High-quality CPR maintains coronary and cerebral perfusion, which increases the likelihood that defibrillation will restore a perfusing rhythm.

During ACLS training, a learner is unable to identify a shockable rhythm within the 2-minute cycle. What should the team leader do?

Answer: Provide closed-loop communication and redirect the team

Closed-loop communication and clear redirection are key ACLS team leader skills to keep resuscitation on track.
