2024
Right ventricular infarction (RVI) lead changes - II, III, AVF
R ventricular infarction s/s - clear breath sounds, hypotension, JVD.
R ventricular dilation and dec contractility>> dec preload and CO
Reperfusion therapy standard - Within 60 min of ED arrival
Common causes of PEA - Hypoxia, tension pneumo, cardiac tamponade
BNP as a marker - of L ventricular dysfunction bc ventricles make BNP and an inc of
over 100 pg/ml indicates symptomatic HF
Transcutaneous pacing (TCP) - 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 - 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 - 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 - 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 - With bradycardia, Osborne (J) waves and prolonged QT
intervals
Sick sinus syndrome - Sinoatrial node (SA) the primary heart pacemaker is not
functioning properly resulting in bradydysrythmias and/or tachydysrhythmias with
potential for hypotension and syncope
Morphine and nitrates for tx pulmonary edema - Results in dec preload or dec venous
return>> dec pulmonary congestion
How to diagnose endocarditis - Echocardiogram
Pericardiocentesis - For suspected pericardial effusion or tamponade
Primary complication of bowel obstruction - Dehydration
Testicular referred pain is indicative of? - Duodenal injury
S/s pancreatitis - Sharp, boring, epigastric pain, inc after eating and having alcohol
Dx with abd CT scan
Paracentesis - Procedure to remove fluid that has accumulated in the abd cavity
After doing paracentesis - Check pt for s/s shock, EKG, dressing, VS q 15 min
Auscultate bowel obstruction - Freq and high pitched
Dec or absent bowel sounds caused by - Paralytic ileus, paralysis, dec in peristalsis
One cause of HYPOkalemia - Excess fluid loss from GI (ex: diarrhea)
One cause of Magnesium depletion - Intestinal malabsorption
Bland diet is for - Peptic and gastric ulcers
Chocolate enhances - S/s GERD
Life threatening complications of acute pancreatitis - Atelectasis, pleural effusion, ARDS
HELLP syndrome - Hemolysis, Elevated liver enzymes, Low platelets)
Liver panel dx it
S/s rhabdomyolysis - HYPERkalemia, brown urine, inc CPK, HYPERcalcemia
Septal hematoma - Can occur with mid facial trauma; untreated can lead to abscess
formation or avascular necrosis
Ethmoid bone fx can cause - CSF leakage
Preferred eye irrigation fluid - LR
Pocket vision screener should be held ___ inches from nose? - 14 inches
HHNC s/s - UA shows glycosuria without ketouria, polyuria, tachycardia, hypotension
