The nurse is preparing to administer amitriptyline 10 mg orally to the client diagnosed with IBS. The client asks, ÔÇ£Why am I receiving this? I donÔÇÖt feel depressed.ÔÇØ Which response by the nurse is best?

A. Not all clients with chronic diseases suffer from depression. The response does not address the primary reason for the use of a TCA such as amitriptyline (Elavil) in IBS. B. A common response to TCAs is sedation; however, this medication is not given for this reason. C. TCAs do have anticholinergic side effects and can cause (not prevent) constipation. Clients with IBS can have constipation or diarrhea. D. Evidence supports that TCAs can reduce abdominal pain, and this benefit is unrelated to whether or not the client is being treated for depression.
