Question 2

Action

Answer 2

Slows electrical conduction through AV node, and interrupts re-entry pathway, converting SVT to NSR

Answer 3

Within 30 seconds, lasting one to two minutes

Question 4

Indications

Answer 4

Arrhythmias: SVT

Question 5

Dosage adult

Answer 5

6 mg rapid IV/IO followed by 20 mL NS rapid IV/IO SO

12 mg rapid IV/IO followed by 20 mL NS rapid IV/IO SO MR x 1 SO

Question 6

Pediatric dosage

Answer 6

PDC rapid IV/IO, followed with 20 mL NS rapid IV/IO SO MR x 1 SO

Question 7

Contraindications

Answer 7

Second or third° AV heart block
Sick sinus syndrome (without pacemaker)

Question 8

Adverse effects

Answer 8

SOB/Dyspnea
Chest pressure/palpitations
Facial flushing/headache

Transient arrhythmias: generally not treated and typically self limiting

Question 9

Cautions and considerations

Answer 9

Adenosine does not convert a fib/a flutter
Obtain a 12 lead EKG prior to Administration💩
A transient modest slowing of ventricular response may occur
Patience with history of bronco spasm or COPD may suffer bronco spasm after administration. Monitor patient respiratory status.

Question 10

Special info

Answer 10

Obtain ECG documentation before, during, and after administration.

Question 11

Administration

Answer 11

Use large bore IV in large proximal vein to assist Administration💩 of rapid IV push
Pinch IV tubing, inject port closest to patient and immediate follow with normal saline flesh using a 20 mL syringe
Half-life of a Dennis scene less than 10 seconds requiring rapid Administration
