A nurse is reviewing information about advance directives with a newly admitted client. Which of the following statements by the client indicates an understanding of the information?

"I should discuss this document with my family after I sign it"

Advance directives are legal documents that allow an individual to specify the type of medical care they want to receive in case they become unable to make their own decisions. It is important for the client to discuss their wishes with their family members or loved ones so that they are aware of the client's desires and can act accordingly in case of an emergency.

"I am not allowed to change my mind once I sign this document" is incorrect. The client can change their mind about their advance directive at any time and for any reason. It is important for the client to review their advance directive periodically and make changes as necessary.

"An attorney will need to notarize this document for it to be valid" is also incorrect. While some states require advance directives to be notarized or witnessed, not all states do. It is important for the client to check with their state's laws regarding advance directives to ensure that their document is legally binding.

"My partner needs to be present when I sign this document" is not necessarily true. While it is recommended for the client to have a witness present when signing their advance directive, it does not have to be their partner. The witness should be someone who is not a family member, healthcare provider, or beneficiary of the client's estate.

Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, it is important to monitor the client's clotting ability to ensure that the medication is working properly and not causing any adverse effects. The laboratory test that is used to monitor warfarin therapy is the prothrombin time (PT), which measures the time it takes for the blood to clot. The nurse should monitor the client's PT regularly and adjust the dosage of warfarin as necessary to maintain the therapeutic range. Option a (Triiodothyronine) is a thyroid hormone and is not directly related to warfarin therapy. Option b (Blood urea nitrogen) is a measure of kidney function and is also not directly related to warfarin therapy. Option c (Arterial blood gases) is a measure of oxygen and carbon dioxide levels in the blood and is not related to warfarin therapy.
