A nurse is reinforcing postoperative teaching with a client who has a prescription for enoxaparin to prevent deep vein thrombosis. Which of the following information should the nurse include in the teaching as a potential adverse effect of this medication?

A. "A client must sign an Against Medical Advice form if he withdraws consent.": An Against Medical Advice (AMA) form is specifically used when a client chooses to leave a healthcare facility against medical advice, not when they withdraw consent for a procedure. Withdrawing consent does not require an AMA form and follows a separate legal and ethical process.

B. "A client can withdraw consent at any time after signing the informed consent form.": Clients maintain the right to autonomy throughout their care, including the right to withdraw consent at any point before or during a procedure. Signing the form does not waive their right to change their mind, and healthcare providers must respect this decision without penalizing the client.

C. "A client who is involuntarily admitted to a mental health unit cannot withdraw consent for treatment.": Even clients who are involuntarily admitted retain certain rights, including the right to refuse specific treatments unless they are legally deemed incompetent or pose an imminent threat. Involuntary admission does not mean automatic consent to all treatments.

D. "A client must provide a written refusal for a procedure for which he has already signed an informed consent.": Clients can verbally withdraw consent at any time; a written refusal is not legally required. While documentation of the client's decision is necessary for the medical record, insisting on a written refusal is not a legal prerequisite for withdrawal of consent.

A. Black out the line with a felt-tip pen: Blacking out a space or entry is inappropriate because it obscures the original documentation, making the record appear altered or falsified. Medical documentation must remain clear, transparent, and legally defensible at all times.

B. Draw a horizontal line through the space and sign at the end of the line: Drawing a single horizontal line through the blank space ensures that no unauthorized additions can be made later. Signing at the end of the line maintains the integrity and completeness of the medical record, following accepted documentation standards.

C. Place the date at the beginning of the space, followed by double lines: Simply dating the space without properly securing it with a line could leave it open to later insertions. Double lines are also not a recognized standard method for handling blank spaces in documentation.

D. Leave the space as it is within the entry: Leaving a blank space unmarked can create opportunities for someone to add unauthorized information later. This poses legal and ethical risks and compromises the reliability and security of the medical record.
