Can Dicortineff applied to the ear in an adult cause nausea?

Dicortineff - like any drug - may or may not cause side effects. Not everyone will experience them. In general, Dicortineff is usually well tolerated, and possible side effects are not dangerous. Nausea as a result of dicortineff is not described in the documentation for dicortineff. However, the application of the drug to the ear itself can cause ailments such as nausea if the instilled preparation is, for example, too cold. In addition, since you use Dicortineff for the ear, I conclude that you suffer from inflammation of the ear. Dizziness, nausea, vomiting may be associated with the ear disease itself and may indicate, for example, labyrinthitis. I would suggest reporting this symptom to the doctor.
