Occlusion of the affected coronary artery most likely would affect perfusion to which portion of the conduction system? A. Sinoatrial (SA) node B. Bachmann's bundle C. Atrioventricular (AV) node D. Bundle of His - ANSWERSLAD so D. bundle of his Which of the following is the preferred lead for ST segment monitoring for a patient with a suspected RCA occlusion? A.I B. aVR C....

Distributive: Anaphylactic Cardiogenic: Dysrhythmia Obstructive: Adrenal Insufficiency Hemorrhage: Plasma loss - ANSWERSC A patient having which condition is at higher risk for developing infective endocarditis? Cystic Fibrosis Hydrocephalus Patent ductus arteriosus Bronchopulmonary dysplasia - ANSWERSC Which hemodynamic pressures would be increased in mitral stenosis? Right atrial and central venous pre...

SV is decreased and HR is increased - ANSWERSC The majority of cardiac arrests in kids are due to - ANSWERSRespiratory failure Adrenergic stimulation is one of the compensatory mechanisms used when cardiac output fails. Which of the following is a result of adrenergic stimulation? (cardiac 6) A. Longer diastolic per...

The nurse is caring for a patient with acute inferior wall MI, post-coronary artery stent deployment, For optimal care of the patient, the nurse should: - ANSWERSContinuously monitor the patient in lead II It is best practice to monitor the patient status post PCI with stent, in the lead that was most abnormal during the acute occlusion. The ECG demonstrates ST elevation in leads II, III and aVF. The nurse needs to monitor the patient closely for which of the following? - ANSWERSComplicati...

A patient has had a large anterior myocardial infarction last month and developed a ventricular aneurysm. He now has episodes of ventricular tachycardia that are not prevented or converted with antidysrhythmic agents. An implantable cardioverter-defibrillator (ICD) is implanted. Four days after surgery he develops ventricular tachycardia. The ICD has delivered three shocks but has not converted the rhythm. He is pulseless and apneic. Cardiopulmonary resuscitation is in progress. What is the prio...

A 56 yr-old male is admitted to the ICU with a blood pressure of 225/135 and complains of a headache and nausea. He reports he ran out of blood pressure meds three days ago, but also appears to be confused to the date and situation. What is the most appropriate treatment approach? - ANSWERRapidly lower the diastolic pressure to 100 with IV antihypertensive meds, then continue to gradually reduce the diastolic pressure to 85 with oral antihypertensive meds. The maximum initial decrease should...
