A client who has a serum potassium level of 5.9 mEq/L (5.9 mmol/L) tells the nurse of deciding to leave the hospital, even though the healthcare provider has not discharged the client. The client states, "I do not care if I am not discharged, I do not want any more treatment." It is most important for the nurse to ensure that the client understands which fact prior to leaving the facility? Reference range

A. Telling the client they can return at any time is true but does not address the urgent need for them to understand the immediate danger of untreated hyperkalemia. B. The client should know they can return to the hospital at any time: This is true, but it is not the priority compared to understanding the immediate, serious risk. C. Inform the client that insurance will not pay: This is incorrect and inappropriate; insurance payment is not the nurse’s focus and should not be used to influence the decision. D. When a client chooses to leave against medical advice (AMA), the nurse’s most important responsibility is to ensure the client has informed understanding of the risks of leaving. A potassium level of 5.9 mEq/L indicates hyperkalemia, which can cause life-threatening cardiac dysrhythmias and sudden death. The client must clearly understand the potential consequences, including death, before leaving so the decision is truly informed.
