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

Answer and Explanation

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 B

Explanation

A. surgery has caused an episode of supraventricular tachycardia: While stress or surgery can trigger arrhythmias, the ECG shown demonstrates a sinus tachycardia pattern (narrow QRS complexes with identifiable P waves before each QRS), not supraventricular tachycardia (SVT), which typically has a very rapid, regular rhythm often without visible P waves.

B. is febrile which is causing the heart rate to be elevated: The client has a temperature of 102°F (38.8°C), which can increase metabolic demand and lead to sinus tachycardia. Fever is a common and expected cause of elevated heart rate, especially when accompanied by infection, such as the client’s post-op wound infection.

C. is in heart failure and the heart rate is elevated to compensate: There is no evidence from the scenario (no dyspnea, crackles, edema, or reduced BP) that supports heart failure. The elevated HR is more directly related to the fever and infection, not cardiac decompensation.

D. probably has a low oxygen saturation causing an increased respiratory rate: The respiratory rate is slightly elevated (22/min), but there is no mention of hypoxia or oxygen saturation levels. Tachycardia secondary to hypoxia would require clinical indicators of respiratory distress or desaturation, which are not demonstrated.

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.
