A client is admitted with uncontrolled atrial fibrillation with a rate between 120's-130's. IV heparin therapy is prescribed. In addition, the nurse prepares the client for a transesophageal echocardiogram (TEE). What does the nurse understand about this diagnostic study?
The TEE evaluates if emboli are present if cardioversion is required
The study will use electric current to stop the abnormal conduction pathway
A TEE will help restore the client's underlying baseline normal rhythm,
A TEE is required prior to implantable defibrillator placement in clients with atrial fibrillation
The Correct Answer is A
A. The TEE evaluates if emboli are present if cardioversion is required: A transesophageal echocardiogram (TEE) provides detailed imaging of the heart’s chambers, particularly the left atrium and left atrial appendage, where clots often form in atrial fibrillation. It is used to rule out thrombi before cardioversion to reduce the risk of stroke during the procedure.
B. The study will use electric current to stop the abnormal conduction pathway: This describes electrical cardioversion, not TEE. TEE is a diagnostic imaging procedure and does not involve the delivery of electrical currents to modify the heart's rhythm or conduction.
C. A TEE will help restore the client's underlying baseline normal rhythm: TEE does not treat arrhythmias. Its role is diagnostic—to visualize cardiac structures, not to restore normal rhythm. Cardioversion or pharmacologic agents are required to correct atrial fibrillation.
D. A TEE is required prior to implantable defibrillator placement in clients with atrial fibrillation: TEE is not routinely required before implantable cardioverter-defibrillator (ICD) placement. ICD decisions are usually based on ejection fraction, rhythm stability, and risk of sudden cardiac arrest, not the presence or absence of atrial thrombi.

Correct Answer is ["200"]
Explanation
Volume ordered is 1 L.
Convert the total volume to milliliters (mL)
1 L = 1000 mL.
Total volume in mL = 1 L × 1000 mL/L = 1000 mL
Total infusion time = 5 hours
Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total volume (mL) / Total infusion time (hours)
= 1000 mL / 5 hours
= 200
The appropriate setting is 200 mL/hr.
Correct Answer is B
Explanation
A. Administer the dose later in the day when their nausea subsides: Delaying the dose does not address the underlying concern of potential digoxin toxicity. Symptoms like nausea and visual disturbances suggest toxicity and require immediate assessment rather than postponement.
B. Assess the client's apical rate: The first and most appropriate nursing action is to assess the apical heart rate for one full minute, as bradycardia is a key indicator of digoxin toxicity. If the rate is below 60 bpm, the dose should be held, and the provider should be notified.
C. Contact the physician for STAT serum potassium level: Hypokalemia increases the risk of digoxin toxicity, but while checking potassium is important, it is not the first step. Assessment of heart rate is more immediately critical in evaluating the need to hold the medication.
D. Administer the client's prescribed dose intravenously: Administering the dose especially IV when the client has symptoms of toxicity could worsen the situation. Digoxin should be held, not given, until further evaluation and provider notification.
