A nurse is caring for a client who has a prescription for warfarin.

Which of the following laboratory tests should the nurse monitor?

a. "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.

b. "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.

c. "An atorney 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.

d. "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.

Iron supplementation commonly causes constipation, which is due to the iron's effect of slowing down bowel movements and increasing water absorption in the intestines.

Dry mouth is not a common adverse effect of iron supplementation. It is more commonly associated with medications that can cause xerostomia (dry mouth), such as certain antihistamines or anticholinergic drugs.

Tinnitus, a perception of ringing or noise in the ears, is not typically associated with iron supplementation. Tinnitus can be caused by various factors, such as exposure to loud noises, ear infections, or certain medications, but it is not directly related to iron supplementation.

Hematuria, the presence of blood in the urine, is not a common adverse effect of iron supplementation. It can be caused by various conditions affecting the urinary system, such as urinary tract infections, kidney stones, or bladder issues, but it is not directly related to iron supplementation.
