Which uterotonic agent is the first-line choice for active management of the third stage of labor according to WHO guidelines?
Answer: Oxytocin
Oxytocin (10 IU IM) is the WHO-recommended first-line uterotonic for active management of the third stage of labor due to its efficacy and favorable side-effect profile.
