NR 341 Exam #2 Unit 3 & 4 Review
What is the 2nd line of defense for sinus bradycardia?
Epinephrin
What is the priority intervention for sinus tachycardia?
Figure out the underlying cause (exercise, fever, HTN, etc.)
What medication do you give for regular sinus tachycardia?
Adenosine
What medication do you give for irregular sinus tachycardia?
Cardizem (Ditalizem)
What are the interventions for atrial flutter?
Slow down ventricular response:
-Give calcium channel blocker
-Cardioversion/radiofrequency ablation
-Give anticoagulant (coumadin/warfarin) = check PT-INR levels
What medications are given for patients with atrial fibrillation?
Initial = heparin
Long term = coumadin/warfarin (monitor PT-INR levels)
A nurse notices a patient's monitor reading vfib, what is the
priority upon entering the patient's room?
Priority intervention is to assess the patient (make sure leads are
attached, etc.). If the patient is actually in vfib = defibrillate
How do you differentiate between atrial and ventricular pacing?
, Atrial pacing: there is a line before the P wave on an EKG
Ventricular pacing: there's a line before the QRS wave on an
EKG
What are the possible complications following a pacemaker
placement?
Infection or bleeding at the insertion site; dislocation of lead;
cardiac perforation leading to tamponade; pneumothorax
What is the priority intervention following a pacemaker
placement?
Monitor respiratory status (possible left-lung puncture during
placement)
What does it mean if a pacemaker has failure to capture?
The pacer spikes but there's no QRS
What does it mean if a pacemaker has a failure to pace?
The pacemaker doesn't pace all the times we need it to
What does it mean if a pacemaker has a failure to sense?
The pacemaker doesn't detect that it needs to fire (person could
have a slow, irregular rhythm; dec. perfusion, poor cap refill,
etc.)
What does it mean if a patient with a newly-placed pacemaker
begins to hiccup?
The phrenic nerve that innervates to the diaphragm is somehow
stimulated by the pacemaker which causes the pt to hiccup
