Question

The patient has an electrocardiographic (ECG) tracing that is 50 beats/minute, the rhythm is regular, and there is a P wave before every QRS complex. The QRS has a normal shape and duration, and the PR interval is normal. What is you response?

A. Administer atropine by intravenous push (IVP).
B. Administer epinephrine by IVP.
C. Monitor the patient for syncope.
D. Attach an external pacemaker.

Answer 1

The patient's ECG shows a normal sinus rhythm with a heart rate of 50 beats/minute. No intervention is necessary given the normal findings and absence of symptoms.

Step-by-step explanation:

The patient in this case has a normal sinus rhythm on electrocardiography (ECG). The heart rate, as indicated by the 50 beats/minute, falls within the normal range. The presence of a P wave before every QRS complex and a normal PR interval suggest that the electrical impulses are being conducted properly through the atria and ventricles.

Given the normal findings on the ECG tracing, there is no indication for administration of atropine or epinephrine, as these medications are used in the management of bradycardia or cardiac arrest. The patient is not experiencing any symptoms of syncope, so monitoring for syncope is not necessary. Additionally, there is no evidence of heart block or severe arrhythmias that would require external pacing. Therefore, no intervention is needed at this time.
