What source of power can an experienced staff nurse effectively use to convince other nurses to follow her?

A) Authority
B) Reward
C) Expert
D) Coercion

Expert power is an experienced nurse's source of power; it allows the nurse to use her knowledge to convince others to follow.Authority is power granted by the organization to an individual or group; because all staff nurses share the same authority,this would not be an effective power source for a single nurse.Because all staff nurses are assumed to have equal ability to use rewards as source of power,this would not be the most effective source of power.Coercion is the threat of pain or harm,which cannot and should not be the source of power used by any nurse.
