A patient in wide-complex tachycardia is hemodynamically unstable with a BP of 70/40 mmHg. What is the immediate treatment?
Answer: Immediate synchronized cardioversion
Hemodynamic instability with wide-complex tachycardia mandates immediate synchronized cardioversion regardless of the underlying rhythm.
During a cardiac arrest resuscitation, what is the recommended dose and frequency of epinephrine administration?
Answer: 1 mg IV every 3-5 minutes
The standard dose of epinephrine during cardiac arrest is 1 mg IV/IO administered every 3-5 minutes throughout the resuscitation.
Which of the following best describes the role of the precordial thump in cardiac arrest management?
Answer: Only considered for witnessed monitored pulseless VT when a defibrillator is not immediately available
The precordial thump may be considered only for witnessed, monitored pulseless VT when defibrillation is not immediately available, as its benefit is uncertain.
A 45-year-old patient presents with acute pulmonary edema secondary to CHF. His BP is 160/100 and SpO2 is 82% on room air. Which intervention is the HIGHEST priority?
Answer: CPAP or BiPAP therapy
CPAP/BiPAP is the highest-priority intervention as it immediately improves oxygenation by increasing mean airway pressure and reducing pulmonary edema.
Atropine is indicated for symptomatic bradycardia. What is the initial adult dose?
Answer: 0.5 mg IV
The initial dose of atropine for symptomatic bradycardia is 0.5 mg IV, which may be repeated every 3-5 minutes to a maximum of 3 mg.
A patient's ECG shows a P wave for every QRS complex, but the PR interval progressively lengthens until a QRS is dropped, then repeats. This pattern describes which dysrhythmia?
Answer: Second-degree AV block Type I (Wenckebach)
Progressive PR interval lengthening followed by a dropped QRS is the hallmark of Wenckebach (Mobitz Type I) second-degree AV block.
Which electrolyte abnormality is most commonly associated with the development of Torsades de Pointes?
Answer: Hypomagnesemia
Hypomagnesemia is the electrolyte abnormality most strongly associated with Torsades de Pointes and is also the treatment of choice (magnesium sulfate 2g IV).
