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

Answer and Explanation

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 A

Explanation

A The first intervention should be to ensure adequate oxygenation, as hypoxia can exacerbate shock. Therefore, providing oxygen at 100% via a non-rebreather mask is the most critical initial step. This intervention helps to maximize the amount of oxygen delivered to the patient's lungs and subsequently to the rest of the body, supporting vital organ function while further assessments and interventions are prepared.

B Continuous ECG monitoring allows for the assessment of the patient's heart rhythm, rate, and any signs of dysrhythmias or cardiac ischemia. This intervention is important for detecting any life- threatening arrhythmias, such as ventricular tachycardia or fibrillation, which may require immediate intervention. While ECG monitoring is important, it may not be the highest priority intervention.

C Drawing blood for type and crossmatch is important for preparing for potential blood transfusions if significant blood loss is suspected. However, this intervention may take some time to process, and immediate stabilization of the patient's condition is paramount.

D Large-bore IV catheters allow for rapid infusion of fluids to restore intravascular volume and improve tissue perfusion. This intervention is critical for stabilizing the patient's hemodynamic status and takes precedence in the management of shock. However, oxygenation should take priority.

A. Administer the prescribed daily dose of metoprolol B. Obtain the client's blood pressure and pulse C. Notify the health care provider about the rhythm D. Print a rhythm strip to document the changes in the health record

Correct Answer is B

Explanation

B. Assessing the client's vital signs, including blood pressure and pulse, provides critical information about the client's hemodynamic status and response to the new rhythm. Atrial fibrillation can lead to rapid, irregular heart rates and hemodynamic instability, so obtaining vital signs promptly helps the nurse determine the severity of the situation and whether immediate intervention is needed.

A. This action is not the priority when the nurse observes a new onset of atrial fibrillation. While beta- blockers such as metoprolol may be part of the client's long-term management for heart failure and atrial fibrillation, initiating medication administration without further assessment could delay appropriate intervention for the acute change in rhythm.

C. While it is important to communicate changes in the client's condition to the healthcare provider, this action should occur after the nurse has assessed the client's vital signs and determined the urgency of the situation. If the client is stable and responsive to initial interventions, the nurse can then contact the healthcare provider to discuss the new onset of atrial fibrillation and collaborate on further management.

D. Documenting the changes in the client's rhythm is important for continuity of care and communication among healthcare team members. However, obtaining a rhythm strip should not be the first action when a new onset of atrial fibrillation is observed. Assessing the client's vital signs and initiating appropriate interventions to address any hemodynamic instability take precedence.
