What is a common side effect of Dexamethasone (Decadron) when used for CINV?

Decreased appetite
Somnolence
Increased appetite
Euphoria

The correct answer is: Increased appetite

One common side effect of Dexamethasone (Decadron) when used for CINV is increased appetite. This is due to the drug's ability to suppress the body's natural inflammatory response, which can cause a decrease in appetite. Option A, decreased appetite, is incorrect because this is the opposite of what is typically seen with Dexamethasone. Option B, somnolence, is incorrect because this is not a common side effect of Dexamethasone. Option D, euphoria, is incorrect because while it is a possible side effect of Dexamethasone, it is not a common one and typically occurs at higher doses. Therefore, the most likely side effect associated with Dexamethasone use for CINV is increased appetite.
