What is Wolff-Parkinson-White syndrome and how is it treated? - ️️There is an extra pathway between your hearts upper and lower chambers causing a rapid heartbeat. Lidocain and amiodarone may be used in treatment, as well as adenosine if experiencing SVT. DON't give verapamil because it slows conduction through the AV node which could lead to severe tachycardias How can you differentiate the cause of jaundice? - ️️An increase in direct bilirubin is associated with biliary obstruction...

A patient's preload is decreased. How should the nurse interpret this information? -the stroke volume has increased -the ventricles have stretched more -the muscarinic receptors are activated -the end-diastolic volume has decreased - the end-diastolic volume has decreased -cardiac preload can be expressed as either end-diastolic volume or en-diastolic pressure; thus, decreased preload is decreased end-diastolic volume or end-diastolic pressure. Which statement is correct regarding the di...
