One of the routersim questions I had on the exam basically said to turn on RIP on a serial port and "broadcast to the other routers."

I knew how to add RIP to the serial interface, but what were they asking with the "broadcast to the other routers" part?

Was this just weird wording or did I need to run other commands once I turned on RIP?

I suppose the question was referring to the routing updates that are "broadcast" to all neighboring routers (every 30 seconds by default).

You don't have to enter anything else except

router rip
interface serial 0
network x.x.x.x

to enable RIP on a serial interface.

kphua is correct in the RIP upd8 intervals, however the commands differ somewhat. There is no need to specify an interface. You only need to specify what classful networks it will route.

From the global config mode:

(config)#router rip
(config-router)#network x.x.x.x

All done!

Bear in mind that RIP v1 (which the CCNA is concerned with), is classful so forget subnet masks and enter only the network address of the default class of network you are routing for. Eg:

(config-router)#network 10.0.0.0
or
(config-router)#network 172.16.0.0
or
(config-router)#network 192.168.1.0

Hope that this was enlightening boss!
