Dysrythmias
What heart rate is characterized by a normal conduction with rates over 100bmp
What is Sinus Tachycardia
The nurse recognizes that this medication may be utilized to prevent cardiac dysrhythmias in patients who have achieved ROSC (return of spontaneous circulation) following CPR.
What is lidocaine
Cardioversion can potentially cause a complication characterized by these symptoms
What is shortness of breath, anxiety, hypoxia (PE)
What is decreased level of consciousness, slurred speech, muscle weakness/paralysis (CVA)
These laboratory tests are used to diagnose an acute MI
What is Troponin, CK and CK-MB
This wave presents ventricular repolarization (the cells regain a negative charge - also called "resting state")
What is the T wave
Hypotension, flushing, and headache can be common adverse effects of what medication?
What is Nitroglycerin
You are the primary nurse caring for a trauma patient that presents with sudden onset dyspnea, chest pain, JVD, and muffled heart sounds after a motor vehicle accident. You suspect what condition?
What is cardiac tamponade
A client presents to the ED with shortness of breath, nausea/vomiting, and intermittent chest pressure over the past 2 days. What lab value would alert the nurse that they had a myocardial infarction?
What is elevated troponin.
Which ECG component represents atrial depolarization?
What is the P wave
You are working in the ER when a patient presents with lightheadedness. The monitor shows a regular rhythm with a heart rate of 46, blood pressure of 104/76. They have a respiratory rate of 20 and are afebrile. You anticipate the provider to order what medication?
What is Atropine.
A 66-year-old female presents to the ER with complains of nausea, mid back pain, and shortness of breath. What would the priority nursing intervention.
What is 12-lead EKG.
Stroke Volume (SV) x Heart Rate (HR) =
What is Cardiac Output (CO)
Name the arrythmia characterized by a sawtooth pattern on ECG.
What is Atrial flutter
A patient presents with heart rate of 135 with complaints of shortness of breath and palpitations. The 12-lead EKG shows SVT. Vagal maneuvers are ineffective. What medication would the nurse expect the physician to order?
What is Adenosine.
What assessment findings would alert the nurse to decrease cardiac output related to a dysrhythmia?
What is hypotension, syncope, or increased heart rate.
What syndrome occurs when cardiac oxygen needs exceed oxygen supply?
What is Angina
This dysrhythmia results from abnormal impulse formation causing rapid, disorganized, and uncoordinated twitching of the atrial musculature.
What is Atrial Fibrillation
What procedure involves the delivery of an electrical current timed to the R-wave of the QRS complex to treat certain arrhythmias like atrial fibrillation?
What is Synchronized Cardioversion.
A patient is brought in by EMS for a suspected STEMI. The patient's monitor now shows ventricular fibrillation. After assessing the patient what is the nurse's priority intervention?
What is Defibrillation
This is often called the pacemaker of the heart.
