• What does A Fib ECG look like? -✓✓ -impulse rate of 350-600 times per minute
-no P waves
-no atrial contractions
-loss of atrial kick
-irregular ventricular response
• How often do you assess vital signs on a patient with a dysrhythmia
(gray box) -✓✓ at least every 4 hours
• Nursing Safety Priority for Sinus tachycardia what to assess
(gray box) -✓✓ -fatigue, weakness, SOB, orthopnea, decreased O2, increased HR,
decreased BP, angina, palpitations
-ECG: T wave inversion or ST elevation/depression
-decreased cerebral perfusion may occur. Symptoms: restlessness and anxiety
-impaired renal function may occur symptoms: decreased urine output.
• The nurse is assessing the client's cardiac rhythm and notes the following: HR 64,
regular rhythm, PR interval 0.20; QRS 0.10. How will the nurse document this
rhythm interpretation in the electronic health record?
A. Sinus tachycardia
B. Sinus bradycardia
C. Normal sinus rhythm
,D. Sinus arrhythmia -✓✓ C
• NURSING SAFETY PRIORITY
patient education with permanent pacemakers include -✓✓ -Avoid strong
electromagnetic fields (magnets and telecommunication transmitters)
-carry pacemaker identification card
-medical alert bracelet
• A fib may lead to -✓✓ -DVT or PE due to blood pooling
-HF
• A fib signs and symptoms -✓✓ -symptoms depend on ventricular rate*
-some patients are asymptomatic*
irregular pulse, poor perfusion, fatigue, weakness, SOB, dizziness, anxiety,
syncope, palpitations, chest pain/discomfort, and hypotension
• Nursing intervention for a PE -✓✓ -stay with patient
-monitor for SOB, chest pain, and hypotension
-initiate a rapid
-notify the provider
• T/F patients on anticoagulation should report bleeding gums to their provider
immediately -✓✓ T
• NURSING SAFETY PRIORITY
,before a cardioversion what needs to be turned off and removed from patient -✓✓
Oxygen
• what does the nurse assess for in a patient with a dysrthymia? -✓✓ Angina,
hypotension, HF, decreased cerebral profusion, and decreased renal profusion.
• How to decrease/prevent dysthymias -✓✓ -avoid vagus nerve stimulation
-take medications
-stop smoking
-avoid caffeine
-alcohol in moderation
-manage stress
• The nurse is caring for client who is experiencing occasional premature
ventricular contractions. What assessment data are most concerning to the nurse?
A. Potassium 4.8 mEq/L
B. Magnesium 2 mEq/L
C. Heart rate 90
D. History of smoking -✓✓ D
• Nursing Safety Priority
1. V tach stable nursing intervention:
2. V tach unstable nursing intervention: -✓✓ 1. administer O2 and confirm with 12
lead ECG (possible amiodarone/lidocaine administration)
2. may case cardiac arrest, assess ABCs, LOC, and O2
, • T/F ventricular asystole is shockable rythm. -✓✓ FALSE
no electrical impulses are present to disrupt
• T/F
V tach and V fib are shockable rhythms. -✓✓ True
disrupt chaotic rhythm allowing SA node signals to restart
• Upon entering a client's room, the nurse finds the client unresponsive. In what
order will the nurse provide care?
A. Begin chest compressions
B. Check carotid pulse
C. Notify the Rapid Response Team
D. Get the crash cart/AED
E. Provide rescue breaths -✓✓ C,D,B,A,E
• 2. A client in the telemetry unit is on a cardiac monitor. The monitor technician
alerts the nurse that there are no ECG complexes, and the alarm is sounding. What
is the first action by the nurse?
A. Suspend the alarm.
B. Call the emergency response team.
C. Press the record button to get an ECG strip.
D. Assess the client and check lead placement. -✓✓ D
• 3. The primary health care provider prescribes warfarin for a client with atrial
fibrillation. Which client statement indicates that additional education is needed?
A. "I need to go to the clinic once a week to have my blood level checked."
