Final answer:
When switching medications for an adult client with substance abuse and schizophrenia, it is important to educate the client and their family about the change in medication regimen, including the difference in administration and potential benefits and side effects.
Step-by-step explanation:
When switching from oral fluphenazine HCl (Prolixin) to IM fluphenazine decanoate (Prolixin Decanoate) for an adult client with a medical diagnosis of substance abuse and schizophrenia, it is important to educate the client and their family about the change in medication regimen.
One key aspect to teach them is the difference in administration. Oral fluphenazine HCl is taken by mouth, while IM fluphenazine decanoate is given as an injection into the muscle.
Additionally, it is important to explain the potential benefits of the change, such as improved medication compliance due to the longer duration of action with the IM form, as well as any potential side effects or monitoring requirements associated with the new medication.
