Final answer:
The nurse should inform Eugena about the time when the pill should be taken and the potential side effects of the pill. The brand name of the pill and the cost of the pill are not important in this situation.
Step-by-step explanation:
The nurse should provide Eugena with information about the time when the pill should be taken. This is important because knowing the prescribed timing of medication is crucial for its effectiveness. If Eugena took the pill at a considerably different time than usual, it may affect the medication's impact and potential relief of symptoms.
The nurse should also inform Eugena about the potential side effects of the pill. This is important for Eugena to be aware of any possible adverse reactions or symptoms she should monitor. Being informed about the side effects can help Eugena decide on the next course of action.
However, the brand name of the pill and the cost of the pill are not essential information for the nurse to provide in this situation.
