Mr. lacuna is an 83-year-old resident of a long-term care facility who has a diagnosis of moderate alzheimer disease. mr. lacuna's physician recently prescribed oral rivastigmine, but he was unable to tolerate the drug due to its gastrointestinal effects. as a result, he has been ordered the transdermal patch form of the medication. when administering this form ofrivastigmine, the nurse shouldresponse feedback: in patients with moderate dementia, it may be necessary to place the patch on the back where it cannot be removed in settings where a nurse will be reapplying the patch. a patient with moderate dementia would not normally self-manage medications. the dosage of rivastigmine is not increased during a short-term exacerbation of symptoms. transdermal patches are never applied to mucous membranes.10
