2024 CEN Sample Test Questions with 100% Correct Answers/ Verified Right ventricular infarction (RVI) lead changes - Correct Answer II, III, AVF R ventricular infarction s/s - Correct Answer clear breath sounds, hypotension, JVD. R ventricular dilation and dec contractility dec preload and CO Reperfusion therapy standard - Correct Answer Within 60 min of ED arrival Common causes of PEA - Correct Answer Hypoxia, tension pneumo, cardiac tamponade 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 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 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) 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 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 Hypothermia associations - Correct Answer With bradycardia, Osborne (J) waves and prolonged QT intervals
