A patient is in pulseless electrical activity (PEA). Which of the 'H's' and 'T's' should be considered first in a drowning victim?
Answer: Hypoxia and Hypothermia
In drowning victims, hypoxia and hypothermia are the most likely reversible causes of PEA and should be addressed immediately.
Which pharmacologic agent is the first-line treatment for symptomatic bradycardia due to increased vagal tone?
Answer: Atropine
Atropine 0.5 mg IV is the first-line agent for symptomatic bradycardia caused by increased vagal tone, blocking muscarinic receptors to increase heart rate.
A 45-year-old develops a wide-complex tachycardia at 160 bpm with a pulse and altered mental status. BP is 70/40 mmHg. What is the priority treatment?
Answer: Synchronized cardioversion at 100 J
Unstable wide-complex tachycardia with hemodynamic compromise requires immediate synchronized cardioversion.
What is the correct dose of adenosine for the first administration in SVT?
Answer: 6 mg rapid IV push
The initial dose of adenosine for SVT is 6 mg given as a rapid IV push followed immediately by a 20 mL normal saline flush.
Calcium chloride is the preferred form of calcium in cardiac arrest because:
Answer: It contains three times more elemental calcium than calcium gluconate
Calcium chloride (10%) provides approximately three times more elemental calcium per mL than calcium gluconate, making it more potent for cardiac emergencies.
A patient with known heart failure presents with acute pulmonary edema, BP 180/110, and SpO2 82%. Which combination is most appropriate?
Answer: Furosemide IV, CPAP, nitroglycerin SL
Hypertensive acute pulmonary edema is treated with CPAP to improve oxygenation, nitroglycerin to reduce preload, and furosemide to promote diuresis.
During a 12-lead ECG interpretation, ST elevation in leads V1-V4 with reciprocal depression in II, III, aVF indicates:
Answer: Anterior wall STEMI
ST elevation in V1-V4 indicates anterior wall STEMI, typically involving the left anterior descending artery territory.
