Final answer:
To avoid restraining an older adult client with dementia who is trying to remove their IV catheter, a nurse should use therapeutic approaches like distraction or ask a family member to provide comfort.
Step-by-step explanation:
A nurse caring for an older adult client with dementia who is agitated and attempting to remove their IV catheter should avoid restraining the client. Instead, the nurse should use a therapeutic approach, such as distraction or redirection, to calm the client without the need for physical restraints. If available, the nurse might also consider involving a family member to stay with the client and provide comfort, which can be a familiar and reassuring presence for the patient. Administering a sedative or securing the IV with a restraint should only be considered when other less invasive approaches have proven ineffective and when necessary for the patient's safety.
