James has been diagnosed with atrial fibrillation and is prescribed warfarin. During a follow-up visit, the nurse reviews important information about the medication. Which statement by James indicates a need for further teaching?
“I will have my INR checked regularly.”
“I can eat as many green leafy vegetables as I want.”
“I will report any signs of bleeding to my provider.”
“I will take the medication at the same time each day.”
The nurse reviews the following ECG strip: Rhythm: Regular; Atrial rate: 300 bpm; Ventricular rate: 75 bpm; P waves: Saw-tooth pattern. Which dysrhythmia does this represent?
Atrial flutter
Atrial fibrillation

Prepare for synchronized cardioversion
Administer adenosine IV push
Which ECG finding is most characteristic of ventricular fibrillation?
Regular rhythm with widened QRS
Saw-tooth flutter waves
P waves preceding each QRS
Chaotic, irregular waveforms with no identifiable QRS
The nurse is caring for a patient with a new pacemaker. Which statement requires immediate intervention?
“I will avoid lifting my arm above my shoulder for several weeks.”
“I will check my pulse daily.”
“I will report any dizziness or syncope.”

The nurse is teaching about nitroglycerin use. Which statement indicates correct understanding?
I will store the tablets in a pill organizer.
I should swallow the tablet whole.
I can take up to three doses, five minutes apart, if pain persists.
I will take nitroglycerin every day to prevent chest pain.

Sophia, a nurse in the cardiac unit, is caring for a patient who is currently undergoing thrombolytic therapy for an acute myocardial infarction. What is the most important assessment Sophia should perform during this therapy?
Check for evidence of internal or external bleeding
Administer subcutaneous heparin routinely
Limit the patient’s mobility completely
Encourage high-protein diet immediately
Henry, a patient with acute coronary syndrome, asks his nurse why morphine is being administered to him. What is the best explanation?
