Critical care HESI 2023 – 55 questions
•
•
latest
• Cardiac
o SVT: supraventricular tachycardia
▪ No p waves seen
▪ Treatment:
• Adenosine – give 6mg, then 12mg, then another 12mg
• Cardioversion if pt not tolerating rhythm
• Don’t defibrillate!!!
▪ Have someone bring crash cart to room
o Atrial fibrillation:
▪ Chaotic atrial activity
▪ Irregularly irregular
▪ Controlled: vent rate < 100
• On digoxin at home and has controlled a fib look at digoxin
level
▪ Uncontrolled: vent rate > 100
▪ P waves are fibrillatory
▪ High risk for clots give anticoagulant
▪ Common in elderly
▪ Holiday heart syndrome: alcohol and emotional stress
o Atrial flutter:
▪ Ventricular rhythm stays regular
▪ Sawtooth waves
▪ Cardiovert!
o Asystole: flat line
▪ Patient is essentially dead
▪ Give CPR and epi
▪ Pulse is gone
▪ Patient in asystole for 20 minutes talk to family, patient is dead
o 3rd degree heart block
▪ Look at patient’s blood pressure, bradycardia
▪ Give atropine, epinephrine, pacemaker
o Alcoholic EKG
▪ Wide QRS and flat T = life threatening
▪ Flat T means hypokalemia
o Peaked t waves are usually from hyperkalemia
o STEMI: ST elevation myocardial infarction
▪ Give thrombolytics within 4 hours of onset
o MI vs. Indigestion
▪ Classic symptoms of MI: dull chest pain radiating down left arm
▪ Women, elderly, pt’s with hx of DM may not have classic
symptoms, instead:
