Latest Updated 2026/2027 (Graded A+)
• Question
Right ventricular infarction (RVI) lead changes
Correct Answer: II, III, AVF
• Question
R ventricular infarction s/s
Correct Answer: clear breath sounds, hypotension, JVD. R ventricular dilation and dec
contractility>> dec preload and CO
• Question
Reperfusion therapy standard
Correct Answer: Within 60 min of ED arrival
• Question
Common causes of PEA
Correct Answer: Hypoxia, tension pneumo, cardiac tamponade
• Question
BNP as a marker
Correct Answer: of L ventricular dysfunction bc ventricles make BNP and an inc of over
100 pg/ml indicates symptomatic HF
• Question
Transcutaneous pacing (TCP)
Correct Answer: A beat after every pacer spike is electrical capture. Beats are wide
complex bc ventricle is paced. Palpate central pulse, pt may still be hypotensive w/
diminished or absent peripheral pulses. Preferred tx with symptomatic brady esp in pts
with acute MI
• Question
Wolff Parkinson-White (WPW) syndrome
Correct Answer: shortened PR interval and widened QRS complex with a delta wave.
When there is an extra electrical conduction path to heart causing electrical signal to
arrive too soon at ventricle (pt presents in tachy)
,• Question
Brugada syndrome
Correct Answer: R bundle branch block with ST segment elevation in leads V1-V3 and inc
risk of sudden cardiac death (SUDS), common in young men
• Question
Wellen syndrome
Correct Answer: T wave changes plus history of anginal chest pain w/o serum marker
abnormalities, EKG lacks Q waves and significant ST segment elevation. Assoc with
critical proximal L anterior descending (LAD) artery stenosis
• Question
Hypothermia associations
Correct Answer: With bradycardia, Osborne (J) waves and prolonged QT intervals
• Question
Sick sinus syndrome
Correct Answer: Sinoatrial node (SA) the primary heart pacemaker is not functioning
properly resulting in bradydysrythmias and/or tachydysrhythmias with potential for
hypotension and syncope
• Question
Morphine and nitrates for tx pulmonary edema
Correct Answer: Results in dec preload or dec venous return>> dec pulmonary
congestion
• Question
How to diagnose endocarditis
Correct Answer: Echocardiogram
• Question

Chocolate enhances
Correct Answer: S/s GERD
• Question
Life threatening complications of acute pancreatitis
Correct Answer: Atelectasis, pleural effusion, ARDS

HELLP syndrome
Correct Answer: Hemolysis, Elevated liver enzymes, Low platelets) Liver panel dx it
• Question
S/s rhabdomyolysis
Correct Answer: HYPERkalemia, brown urine, inc CPK, HYPERcalcemia
• Question
Septal hematoma
Correct Answer: Can occur with mid facial trauma; untreated can lead to abscess
formation or avascular necrosis

HHNC s/s
Correct Answer: UA shows glycosuria without ketouria, polyuria, tachycardia,
hypotension
