NREMT Paramedic Cognitive ExamOperationsMedium
A paramedic is preparing to administer Adenosine for a stable adult patient experiencing supraventricular tachycardia (SVT). The patient weighs 70 kg. What is the correct initial dose of Adenosine to administer?
- A3 mg rapid IV push
- B0.1 mg/kg rapid IV push
- C6 mg rapid IV push
- D12 mg rapid IV push
Show answer & explanationAnswer & explanation
Correct answer: C. 6 mg rapid IV push
The correct initial dose of Adenosine for stable SVT in an adult is 6 mg administered as a rapid IV push, followed by a rapid flush. A second dose of 12 mg may be given if the first dose is ineffective.
Why the other options are wrong
- A. 3 mg is not the standard initial dose for adults.
- B. Adenosine dosing for adults is not weight-based; it's a fixed dose.
- D. 12 mg is the standard second dose, if needed, not the initial dose.
Adenosine Dosing for SVT
Adenosine is an antiarrhythmic medication used to terminate supraventricular tachycardia (SVT) by temporarily blocking the AV node. It is given as a rapid IV push.
- Initial dose: 6 mg rapid IV push.
- Second dose (if needed): 12 mg rapid IV push.
- Always followed by a rapid saline flush.
- Fixed adult dose, not weight-based.
Memory trick: Adenosine's a blur, 6 then 12, make it occur!
