Which body system is responsible for conserving energy and body re-sources: Parasympathetic nervous system 2. which system responds to stress by preparing the body to defend itself: - Sympathetic nervous system (SNS) 3. how is blood flow redistributed by the sympathetic nervous system (SNS)- : blood flow to the muscles is increased while blood flow to GI and integumentary isdecreased 4. how ar...

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 af...

Relias Dysrhythmia Basic B Test Questions and Answers 2023 Dysrhythmia Basic B Test NSR Rate 60-100 beats/minute originates from SA node Regular One P wave before each QRS PR Interval 0.12 to 0.20 seconds QRS Duration 0.04 to 0.10 seconds Sinus Brady Rate is below 60 beats/minute arising from the SA node Follows normal conduction pathways P and QRS complexes have normal duration and pattern
