A nurse is caring for a client who was admitted for atrial fibrillation rapid ventricular rate of 130 beat/min with confusion. The client's blood pressure is 87/50. What order should the nurse expect to receive from the provider?
Tell the patient to bare down
Administer Lidocaine drip
Administer Amiodarone drip
Administer a beta blocker
The Correct Answer is C
C. Amiodarone is a Class III antiarrhythmic medication commonly used for the acute management of atrial fibrillation with a rapid ventricular rate. It works by blocking multiple ion channels, prolonging the action potential duration, and slowing conduction in the atria and ventricles. Amiodarone is often used when other interventions such as vagal maneuvers or beta blockers are ineffective or contraindicated. In this scenario, where the patient is hypotensive and symptomatic, intravenous amiodarone may be administered to control the ventricular rate and stabilize hemodynamics
A. Bearing down, or the Valsalva maneuver, is a vagal maneuver that can sometimes help slow the heart rate in certain arrhythmias by increasing parasympathetic tone. However, it may not be effective or safe in all situations, especially if the patient is hypotensive or confused. In this scenario, immediate pharmacological intervention is likely needed to control the heart rate and stabilize hemodynamics.
B. Lidocaine is not typically used to treat atrial fibrillation with a rapid ventricular rate. Lidocaine is a Class IB antiarrhythmic medication primarily used for the treatment of ventricular arrhythmias, such as ventricular tachycardia and ventricular fibrillation. It is not considered a first-line agent for atrial fibrillation and may not effectively control the ventricular rate in this situation.
D. While beta blockers are commonly used for rate control in atrial fibrillation, they may not be the best choice in this scenario where the patient is hypotensive and symptomatic. Beta blockers can further decrease blood pressure and exacerbate hypotension, especially in patients with compromised hemodynamics. In such cases, other rate-controlling agents like calcium channel blockers or amiodarone may be preferred.

Correct Answer is D
Explanation
D. Asystole represents the absence of electrical activity in the heart and is not amenable to defibrillation. Therefore, the RRT would continue cardiopulmonary resuscitation (CPR) with chest compressions and may administer medications or other interventions as indicated. This statement provides accurate information to the family about the patient's condition and the actions being taken by the RRT.
A. Defibrillation is not indicated for asystole. Asystole represents a flatline on the cardiac monitor, indicating the absence of electrical activity in the heart. Defibrillation is only effective for certain types of cardiac rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia. Therefore, the RRT would not use defibrillation for a patient in asystole.
B. It does not provide the family with information about the patient's condition or the actions being taken by the RRT. Moreover, excluding the family from the patient's care may cause additional distress and prevent them from being present to support their loved one during a critical situation.
C. Cardiopulmonary resuscitation (CPR) is performed to maintain blood flow and oxygenation to vital organs during cardiac arrest. However, it does not restore normal blood flow or circulation. The goal of CPR is to provide temporary support until advanced interventions can be initiated or until return of spontaneous circulation (ROSC) is achieved.
Correct Answer is B
Explanation
B This maneuver, called the Valsalva maneuver, can sometimes help to restore normal heart rhythm in cases of SVT. It involves blowing forcefully into a syringe or performing a similar action that increases intra-abdominal pressure, which can stimulate the vagus nerve and help to slow down the heart rate.
A Defibrillation is a treatment used for life-threatening cardiac arrhythmias, particularly ventricular fibrillation or pulseless ventricular tachycardia. It involves delivering a therapeutic dose of electrical energy to the heart with a device called a defibrillator.
C Drawing troponin levels may be appropriate if there is suspicion of myocardial infarction as the cause of chest palpitations or if there are other symptoms suggestive of acute coronary syndrome. However, in the context of SVT presenting with chest palpitations and a racing heart, the priority is to address the arrhythmia first
D Amiodarone is an antiarrhythmic medication used to treat various types of cardiac arrhythmias, including ventricular and supraventricular arrhythmias. While it can be effective in certain cases of SVT, it is not typically the first-line treatment or the immediate next step in managing SVT in the emergency department.
