NUR234 EXAM 1 STUDY GUIDE QUESTIONS AND ANSWERS
Warfarin (Coumadin) - CORRECT ANSWER✅✅Medication used to prevent blood clots.
Check for PT/INR. If supratherapeutic, give Vitamin K
Adenosine (Adenocard) - CORRECT ANSWER✅✅For pt with unstable SVT. Given rapidly via IVP and
flushed rapidly. Pt must be connected to an EKG.
Beta Blockers - CORRECT ANSWER✅✅Negative chronotropic and negative inotropic. Given to slow
down HR for people with fast arrhythmias
Calcium Channel Blockers - CORRECT ANSWER✅✅Verapamil and Diltiazem are an example of this
medications. It slows down the HR for people with
tachycardia and irregular HR
Digoxin - CORRECT ANSWER✅✅Do not give if patient is hypokalemic. It is a positive inotrope and a
negative chronotrope.
Check for blood level if complaining of visual disturbance and N/V.
Atropine - CORRECT ANSWER✅✅Given for patient with symptomatic bradycardia. Side effect is dry
eyes because it is an Anticholinergic
Lidocaine - CORRECT ANSWER✅✅This medication prevents sodium to enter the cardiac cells. Prevents
dysrhythmias.
Amiodarone - CORRECT ANSWER✅✅This is an antiarrhythmic that blocks potassium, slowing down
cardiac conduction.
Can cause Blue- Man syndrome
Epinephrine - CORRECT ANSWER✅✅Given during a code to increase cardiac output and improve
perfusion.
, Pradaxa (Dabigatran)
Ribaroxaban (Xarelto)
Apixaban (Eliquis) - CORRECT ANSWER✅✅These are Novel Oral Anticoagulants for patients with Afib or
pacemakers
Normal Sinus Rhythm (NSR) - CORRECT ANSWER✅✅The stimulus must come from the SA node
• The HR must be between 60-100 beats / minute
• The conduction must travel within the speed limit
• PR interval = 0.12-0.20 seconds (If longer than 0.20 we have a 1ST DEGREE AV
BLOCK)
• QRS = 0.06 - 0.12 seconds (If longer than 0.12 we have a BUNDLE)
• Distance from R-R must be evenly spaced-out
• The current must follow the conduction pathway
Atrial Fibrillation (Afib) - CORRECT ANSWER✅✅No P waves visible, R-R irregular
Controlled or Stable- BB, CCB, Digs blood thinners
Unstable/Uncontrolled- Cardioversion
Supraventricular Tachycardia (SVT) - CORRECT ANSWER✅✅No P-waves, Regular R-R
Controlled or Stable- BB, CCB, Digs blood thinners, Vagal maneuvers
Unstable/Uncontrolled- Adenosine, Cardioversion
Sinus Tachycardia (ST) - CORRECT ANSWER✅✅Rhythm more than 100 (usually up to 150) beats per
minute
regular, P and QRS present, 1:1, and normal intervals
Treat the cause
Vagal maneuvers
