A client who is on the progressive care unit develops supraventricular tachycardia (SVT). The clients vital signs: T: 98, HR: 160, BP: 119/71, RR: 19, Sp02 94% on RA. The client presents with no dyspnea, shortness of breath or chest pain. Which action that is included in the hospital dysrhythmia protocol should the nurse do first?
Perform immediate defibrillation.
Perform immediate cardioversion.
Administer Adenosine 6 mg IVP.
Administer Adenosine 12 mg IVP.
The Correct Answer is C
A. Defibrillation is used for life-threatening arrhythmias like ventricular fibrillation or pulseless ventricular tachycardia, not for SVT.
B. Cardioversion is appropriate for certain arrhythmias, but in this case, SVT with a stable pulse can be treated initially with medication like adenosine.
C. Adenosine is the first-line treatment for SVT. The typical starting dose is 6 mg IVP, which can be repeated if necessary. Adenosine works by temporarily blocking the electrical conduction through the AV node, allowing the heart to reset to a normal rhythm.
D. A 12 mg dose of Adenosine is used if the 6 mg dose is ineffective, but the 6 mg dose is typically administered first.
