Then you need to "accidentally" remove it ... pronto, which may mean flushing out the entire coolant system if the engine has been run.
You drain the oil immediately. If you run the engine with coolant mixed with the oil you will do serious harm to the engine. If you continue to drive it in this condition you will destroy the engine.
Have the coolant changed immediately and you will be ok.

Yes. By little I'm talking two tablespoons. If more, then purge and refill with coolant and water.
Accidentally mixing engine coolant with oil can severely damage your car's engine. The coolant can dilute the oil, reducing its lubricating properties and leading to increased friction and wear on engine components. This combination can also cause sludge buildup, which can clog oil passages and lead to overheating or engine failure. If this happens, it's crucial to have the oil changed and the system flushed as soon as possible to mitigate damage.
you run the risk of major bearing fatlure.
After coolant is added run vehicle to normal operating temperature and re-check coolant level
