1. 10 days
2. 10 seconds
3. 10 hours
4. 10 minutes

Rationale 1: The half-life is 10 seconds.
Rationale 2: Adenosine (Adenocard, Adenoscan) is given as a 1-to2-second bolus IV injection to terminate serious atrial tachycardia by slowing conduction through the AV node and decreasing automaticity of the SA node. Its primary indication is a specific dysrhythmia known as paroxysmal supraventricular tachycardia (PSVT), for which it is a drug of choice. Because of its 10-second half-life, adverse effects are generally self-limiting.
