Question
A 35-year-old client in stable narrow-complex supraventricular tachycardia (HR 192) is ordered adenosine 6 mg IV rapid push after vagal maneuvers fail. Which set of nursing actions reflects correct technique and safety?
1Administer over 30-60 seconds via a peripheral hand IV; the client should not feel anything unusual.
2Use the antecubital or other large proximal IV with a stopcock; push the adenosine over 1-2 seconds and immediately follow with a 20 mL normal saline flush; warn the client of brief chest tightness, flushing, or a sense that the heart "stops"; have continuous ECG, BP, and resuscitation equipment ready.✓ Correct answer
3Mix the adenosine in 250 mL of D5W and infuse over 30 minutes for safety.
4Administer the dose IM in the deltoid because IV access is unstable.
