Answer and Explanation

B. A client with syncope who is being discharged today: This client is stable if being discharged, so assessment can be delayed.

C. A client scheduled for a cardiac ultrasound this morning: This is a non-urgent diagnostic procedure and does not take priority.

Correct Answer is ["B","C","D","E"]

Explanation

A. Facilitates the insertion of a pacemaker: This is not the purpose of an electrophysiology study (EPS). A pacemaker may be considered based on the results, but EPS itself does not insert the device.

B. Assesses the function of the SA node: EPS is used to assess the electrical activity of the heart, including the function of the SA node.

C. Evaluates the effectiveness of prescribed antiarrhythmic medication: EPS can help evaluate how well antiarrhythmic medications are controlling arrhythmias.

D. Identifies the location of abnormal sites within cardiac muscle: EPS is often used to locate areas of the heart responsible for abnormal electrical conduction and arrhythmias.

E. Treats certain arrhythmias through the process of ablation: One of the therapeutic purposes of EPS is to perform ablation, which can treat certain arrhythmias by destroying abnormal tissue.

A. Aspirin 325mg po B. Non-contrast computed tomography (CT) scan C. Electrocardiogram (ECG) D. Simvastatin (Zocor) 80 mg po

Correct Answer is B

Explanation

A. Aspirin 325 mg PO: Aspirin is important for preventing clot formation but should not be administered until a hemorrhagic stroke is ruled out.

B. Non-contrast computed tomography (CT) scan: This is the priority because it determines whether the stroke is ischemic or hemorrhagic, guiding further treatment.

C. Electrocardiogram (ECG): While assessing cardiac rhythm is important, it is not the immediate priority in the presence of stroke symptoms.

D. Simvastatin (Zocor) 80 mg PO: Statins are used for long-term management but are not urgent in this acute scenario.
