A patient has experienced an upset stomach from a medication taken previously and is concerned about the possibility of additional side effects. What is the best nursing response?

"It is difficult to tell if you will have this reaction again."

"This is a mild side effect and may not lead to additional side effects. If it were to occur, there may be ways to reduce the side effects.

"You should not take this medication again, as the same thing might happen."

"This is not a serious side effect, so there is no concern."
