A nurse is assessing a client who has a magnesium level of 4.4 mEq/L (1.3 to 2.1 mEq/L). Which of the following findings should the nurse expect?

A. "My living will names my health care surrogate, who will be responsible for my medical expenses.": A health care surrogate is designated to make medical decisions if the client is unable, not to manage financial obligations. Advance directives focus on treatment preferences, so this statement reflects a misunderstanding of their purpose.

B. "Having advance directives requires participation in organ donation.": Advance directives do not require organ donation. Organ donation is a separate legal decision and can be indicated independently of advance directives. Associating the two shows a misconception about advance directive requirements.

C. "Advance directives are not legally enforceable unless signed by an attorney.": Advance directives are legally recognized when properly witnessed or notarized, depending on state law, but do not require an attorney’s signature. This statement overstates the legal requirements, indicating incomplete understanding.

D. "My advance directives communicate my decision to remain on a breathing machine.": Advance directives allow clients to express treatment preferences, including life-sustaining interventions. This statement demonstrates accurate understanding that advance directives guide health care decisions when the client cannot communicate.

A. Instruct visitors to stand 0.6 m (2 feet) away from the client: While maintaining distance can reduce radiation exposure, standard precautions for sealed implants typically require visitors to be limited in time and distance, but the priority for staff is proper protective equipment rather than only instructing visitors.

B. Wear a lead apron when providing care for the client: Wearing a lead apron is essential for staff safety when caring for a client with a sealed radiation implant. The apron shields the nurse from radiation exposure, which is the primary protective measure during direct care.

C. Remove all bed linens from the client's room each day: Frequent removal of linens is unnecessary for sealed radiation implants because the radiation source is contained. Standard precautions for linen handling are sufficient unless the linens are visibly contaminated with bodily fluids.

D. Place a dosimeter film badge at the client's bedside: Dosimeter badges are worn by staff to monitor personal radiation exposure, not placed at the client’s bedside. Proper usage involves staff wearing the badge on their body while providing care.
