Are all cardiac arrests due to problems that respond to defibrillation?
Not all cardiac arrests are due to problems that respond to defibrillation. B. The patient may need medications to support his cardiac rhythm and blood pressure following successful defibrillation. C. In cases of refractory or recurrent ventricular fibrillation, the use of medications may increase the chances of defibrillating successfully
How is decreased cardiac output (co) identified in cardiac rhythm?
Observe for symptoms of decreased cardiac output (CO). Apply a transcutaneous pacemaker. Observe for symptoms of decreased cardiac output (CO). The rhythm is a type II second-degree atrioventricular (AV) block (i.e., Mobitz II). The rhythm is identified by noting P waves that are nonconducted without progressive PR lengthening.

What does the nurse note when auscultating the patient's heart rate?
A patient states, "I feel tired all the time, and I struggle with activities of daily living." When auscultating the patient's heart rate, the nurse notes disorganization of atrial electrical activity and records a rate of 120 bpm. Which rhythm does the nurse anticipate observing?
What is the first step in defibrillation?
The healthcare team will have to perform defibrillation, and the first step is to turn on the defibrillator or AED. Applying conductive gel pads is always completed after the device has been turned on. Proper energy level selection and rhythm analysis is only completed using a defibrillator; they cannot be done with the AED.
What are the findings of a patient's assessment findings?
A patient's assessment findings include dizziness, shortness of breath, heart palpitations, and paroxysmal supraventricular tachycardia (PSVT). The nurse obtains a prescription for adenosine. Which statement is true about the medication?
What is the heart rate of a patient with sinus bradycardia?
The patient will not have a pulse and will not be responsive if the rhythm is ventricular fibrillation or asystole. A patient with sinus bradycardia will have a heart rate less than 60 bpm.
What is a permanent pacemaker?
A permanent pacemaker helps to maintain the normal cardiac pace and is implanted within the body. The power source of such a device is placed subcutaneously, usually over the pectoral muscle on the patient's nondominant side. The permanent pacemaker is used in cardiomyopathy, SA node dysfunction, and third-degree AV block when the dysfunction of the electrical pathways is assumed to be permanent or irreversible. A temporary pacemaker may be required during coronary angioplasty and during drug therapy that may cause bradycardia. To maintain adequate cardiac rhythms during postoperative recovery and as a prophylactic measure after open heart surgery, temporary pacemakers are used.
What is the difference between contractility and automaticity?
Contractility enables the cardiac cells to respond mechanically to an impulse. Automaticity provides the ability to initiate an impuls e spontaneously and continuously. Excitability enables the cardiac cells to be electrically stimulated. Conductivity allows transmission of an impulse along a membrane in an orderly manner.
Does medication decrease conduction?
The medication decreases conduction through the AV node.
What is the heart rate of a patient with atrial fibrillation?
A patient who has a diagnosis of atrial fibrillation as a heart rate of 152 beats per minute. The healthcare provider should assess for which of these problems related to the dysrhythmia?
Why is heparin given for atrial fibrillation?
Because blood tends to pool and clot in the fibrillating atria, patients with atrial fibrillation are at high risk for embolic stroke, so heparin will be given.
What happens to the heart when the stroke is not palpable?
Atrial kick is lost and cardiac output is diminished. The result is less blood supplying the brain (dizziness), hypotension, less blood perfusing the coronary arteries, and a pulse deficit because the stroke volume is not sufficient to produce a palpable peripheral pulse.
What is a CCU nurse?
A coronary care unit ( CCU) nurse is caring for a client admitted with acute myocardial infarction (MI). The nurse monitors for which most common complication of MI?
Is there scar tissue in the ventricle?
There may be some scar tissue in one of the ventricles.

Is there scar tissue in the ventricle?
There may be some scar tissue in one of the ventricles.
Which system of the heart controls the ability of the heart to pump blood?
the conduction system of the heart and the inherent rhythmicity of cardiac muscle which greatly influences the heart's ability to pump blood effectively.
What is it called when your heart beats at a dangerous high rate?
Dysrhythmia in which heart rate has a consistent rhythm but beats at a dangerous high rate.
What is the term for lack of oxygenated blood to the heart muscle?
Myocardial ischemia or lack of oxygenated blood to the heart muscle, which can occur secondary to CAD, CHF, inadequate ventilation & shock.
Which disease proceeds normally through the conduction pathway but at a faster than usual rate?
Dysrhythmia that proceeds normally through the conduction pathway but at a faster than usual rate.
Which node conducts only impulses to the ventricle?
The AV node conducts only some impulses to the ventricle.
What is conduction disorder?
Conduction disorder that results in an abnormally slow or rapid heart rate or one that proceeds through the conduction system as usual.
What is the term for a serious compression of the heart caused by too much fluid between the layers of the peri?
streptokinase . a serious compression of the heart caused by too much fluid between the layers of the pericardium. cardiac tamponade. 408. a slow heart rhythm, bradycardia. 409. :a type of hardening of the arteries. atherosclerosis.
Why is the fluid between the two layers of the pericardium important?
The fluid between the two layers of the pericardium helps to reduce the friction caused by the beating heart. D) d. All of the above are true of the pericardium. The parietal pericardium is also called the epicardium. A patient has been admitted after the insertion of a pacemaker because of bradycardia.

A. Ventricular fibrillation is not the primary cause of cardiac arrest in the pediatric patient.
What does a nurse note about sinus rhythm?
A nurse notes that a client with sinus rhythm has a premature ventricular contraction that falls on the T wave of the preceding beat. The client’s rhythm suddenly changes to one with no P waves or definable QRS complexes. Instead there are coarse wavy lines of varying amplitude. The nurse assesses this rhythm to be:
What does a nurse notice when watching a cardiac monitor?
A nurse is watching the cardiac monitor and notices that the rhythm suddenly changes. There are no P waves, the QRS complexes are wide, and the ventricular rate is regular but over 100. The nurse determines that the client is experiencing: Ventricular fibrillation. Sinus tachycardia.
