Nothing can go wrong. deep T wave inversion in leads V2 and V3, enzymes and trop will be (-) for MIWhen the depth of the S wave in lead V1 or V2 plus the height of the R wave in lead V5 or V6 is 35 mm or greater, this constitutes voltage criteria for _____________ hypertrophy.bleeding time is a reflection of ______________ functionan amino acid that can trigger a hypertensive crisis in a patient taking MAO inhibitorsnitroglycerin dosages must be above 1 mcg/kg/min to achieve (arterial/venous) dilating effects.sudden cardiac death associated with a high speed projectile object causing an unexpected, blunt, non-penetrating blow to the precordium or left lateral chest wallBNP is correlated with ______ and LVEDP because it is released in response to increased intravascular volumeAtrial contraction and propulsion of blood into a noncompliant ventricle produces what heart sound?Rapid ventricular filling into an already distended ventricle produces what heart sound?heart sound a/w opening of a defective semilunar valvea split S2 is abnormal only if it occurs during _________________.a decrease in systolic pressure by 10 mm Hg or more during inspirationIf the ventricles are depolarized before the atria in a junctional rhythm, the P wave will be (before/after/lost in) the QRS complex.AV nodal blocks are common after ________ valve replacements because of the proximity of the AV node to this valvediseased vessels are ____________ and are not capable of dilation.murmurs of atrioventricular valve regurgitation are _____ pitched.murmurs of semilunar valve (aortic and pulmonic) stenosis are _____ pitched.murmurs of semilunar valve (aortic and pulmonic) regurgitation are _____ pitched.triggered activity, related to __________________ problems, is the cause of torsades de pointesEnhanced _______________, usually associated with catecholamines, is the most common cause of ectopic beats.a sound occurring in early diastole caused by a rapid opening of a stenotic mitral valvetwo most common dysrhythmias associated with Wolff-Parkinson-White syndromeA thoracic aortogram would show leakage of _____ with aortic rupture.During this phase of the cardiac cycle, the cardiac valves are closed and contraction occurs without a change in volume, in order to generate a pressure high enough to overcome the resistance in the arterial (pulmonary or systemic) circulation, to open the semilunar valves (pulmonic or aortic), and to propel blood into the great vessels (pulmonary artery or aorta).fatal ischemia and infarction of the LV -> can only be dilated if already "protected" by a bypass graftInflation of a balloon to dilate the left main coronary artery could result in what?Lidocaine and amiodarone can increase the ___________ period of the accessory pathway, which increases the chance that the atrial impulse will go through the AV node rather than the accessory pathwayBecause VT is most likely to originate in the LV, lead _____, which is normally predominantly negative, would be predominantly positive in VTdrugs used for first-line therapy for chronic management of hypertensionthe only escape rhythm available below the bundle of HisIf a junctional impulse reaches the atria and the ventricles at the same time, how will the P wave appear?a murmur of ____________ ________________ is often present in dilated cardiomyopathy as a result of ventricular dilation and stretching of the mitral valve ring.arrhythmia that occurs as a result of changes in ventricular filling and therefore preload caused by breathingprocainamide can increase the QT interval by ___% or moreWhat part of the EKG waveform represents conduction through the atrioventricular node?cardiac phenomenon where short after long is likely to be conducted aberrantlyscan in which newly infarcted areas appear as "hot spots" from 1 to 7 days after a MI (hyperkalemia/hypokalemia) causes flaccid paralysis by partially depolarizing the muscle cell membrane, preventing further depolarization.A BP variation of up to _____ mm Hg between the arms is normala variation of >15mmHg between arm BPs can be indicative of what fatal condition?The right atrial pressure (RAP) can be estimated by adding the ___ cm that the angle of Louis is above the right atrium (i.e. The Adult Critical Care Nurses Certification is a way for nurses to provide tangible proof of their skill and expertise in caring for acutely/critically ill adult patients. The study guide covers all systems and explains them thoroughly. Read the guide carefully and with dedication. Covering the topic of Cardiac tamponade and when it occurs, when it increases, when it decrease, and the different symptoms that brings. You will get your score report immediately after taking the test. evidenced by pacing spikes occurring on time, regardless of the patient's intrinsic rhythm.Which leads are most helpful in differentiating VT from a SVT with aberrancy?S3 and S4 are best heard with the _____ of a stethoscope since they are lower pitchedover the apex, preceding S1, using the bell of a stethoscopeNitrites and nitrates such as nitroglycerin, nitroprusside, and nitric oxide can cause __________________Normal parameters are 100% out, 25% use, and 75% reserveNormal parameters are 100% out, 25% use, and 75% reserveRemember that a run of wide QRS complex tachycardia triggered by a PAC is likely a SVT with aberrancy, whereas a run of wide QRS complex tachycardia triggered by a premature ventricular contraction is likely VT.Remember that a run of wide QRS complex tachycardia triggered by a PAC is likely a SVT with aberrancy, whereas a run of wide QRS complex tachycardia triggered by a premature ventricular contraction is likely VT.Staphylococcus is likely to cause sputum to be _________ colored.Pseudomonas is likely to cause sputum to be ___________.Klebsiella is likely to cause sputum to be ____________-colored.Second intercostal space at the midclavicular line on the affected sidewhere would a needle puncture be done in an emergency decompression of a tension pneumothorax?condition in which normal ferrous hemoglobin is converted to ferric hemoglobin, which cannot carry oxygen.
