Nur 245 Exam 1 UPDATED ACTUAL QUESTIONS AND CORRECT ANSWERS
, Sinus Bradycardia SA node fires at a rate less than 60
- symptomatic: fatigue, dizziness, chest pain, syncope, pale/cool skin,
hypotension, weakness, confusion, disorientation, SOB
drugs* BB, CCB
*may be normal in athletes and some people during sleep
Sinus Bradycardia Treatment treat patient with symptoms
- give O2
*IV atropine
if atropine is ineffective, PACING, or dopamine/epinephrine (adrenalin) infusion is
considered
if d/t drugs, may have to hold, d/c, and decrease
Sinus Tachycardia *dizziness, dyspnea, hypotension bc of - decreased CO = increased myocardial
O2 consumption
CAD = angina
discharge rate from the SA node increased bc of vagal inhibition or sympathetic
stimulation
rate 101-200
can be caused from fever, pain, hypotension, hypovalemia, anemia, hypoxia,
hypoglycemia, MI, HF, hypothyroidism, anxiety, fear
- drugs; EPI, NOR-EPI, atropine, caffeine, theophylline, hydralazine
OTC - Sudafed
Sinus Tachycardia Treatment *treat underlying cause
stable pt = vagal maneuver, BB, adenosine, CCB - to decrease HR
unstable pt = cardioversion
Atrial Flutter recurring, regular, narrow, sawtoothed shaped flutter
*CAD, HTN
rate = 200-350
PR variable no measureable
QRS normal
*Increase risk of stroke = give Coumadin
Atrial Flutter Treatment goal* slow ventricular rate response by increasing AV block
control ventricular rate with BB, CCB
- electronical cardioversion may be done to convert to NSR in an emergency
*antidysrhythmics = amiodarone, flecainide, dronedarone
