When administered to a client experiencing these symptoms, the medication works by blocking the action of histamine in the body, which can contribute to nausea and vomiting.
As a result, the client should experience a decrease in these symptoms, providing relief and improving overall comfort. The nurse can evaluate the effectiveness of the medication by monitoring the client's symptoms and observing whether they have improved after receiving the dose of dimenhydrinate.
If the client reports feeling less nauseous and has not vomited since taking the medication, it is likely that dimenhydrinate has been effective in alleviating their symptoms.
Therefore, The correct option is 4.Nausea and vomiting.
