Based on the information in the electronic health record, complete the following sentences using the drop-down lists. The nurse reads the telemetry strip and interprets the client's cardiac rhythm asdropdown. Based on the cardiac rhythm and client assessment, the nurse anticipatesdropdown

Rationale for Correct Answers: Supraventricular tachycardia: The telemetry strip shows a rapid, regular rhythm originating above the ventricles, consistent with supraventricular tachycardia (SVT), and the heart rate is above 150 beats per minute. SVT can cause palpitations, dizziness, or hypotension if sustained, making accurate identification critical for timely intervention. Administering adenosine: Adenosine is the first-line pharmacologic treatment for stable SVT. It transiently blocks AV nodal conduction, which can terminate the reentrant tachycardia and restore normal sinus rhythm. Administration requires rapid IV push with immediate saline flush and continuous monitoring due to potential transient bradycardia or brief asystole. Rationale for Incorrect Answers Atrial fibrillation: This rhythm is irregularly irregular with no identifiable P waves. SVT is regular and very rapid. Sinus tachycardia: This has a normal P wave before every QRS complex and is typically caused by pain, fever, dehydration, or anxiety. It is not treated with adenosine. Defibrillation: This is used for life-threatening rhythms such as ventricular fibrillation or pulseless ventricular tachycardia, not stable SVT. Administering diltiazem: This is commonly used to control ventricular rate in atrial fibrillation, not as first-line treatment for SVT.
