A client who had a knee replacement surgery and received a prescription for enoxaparin 30 mg subcutaneously every 12 hours for 10 days. The medication is available in 30 mg per 0.3 mL pre-filled syringes. How many mL should the practical nurse (PN) administer each day? (Enter numerical value only.)

A is correct because delegating non-nursing tasks to ancillary staff allows nurses to focus on more complex and skilled tasks that require their expertise and judgment, thus improving efficiency and quality of care.

B is incorrect because stocking client rooms with extra supplies increases waste and costs, as well as clutter and infection risk.

C is incorrect because assigning dedicated equipment to each client's room reduces availability and accessibility of equipment for other clients, as well as increases maintenance and cleaning costs.

D is incorrect because changing continuous IV infusion tubing every 24 hr is not cost-effective, as it does not reduce the risk of infection significantly compared to changing it every 72 hr, according to current evidence-based practice guidelines.

A. Advocacy is a leadership role that helps others to self-actualize. This statement is true and reflects one of the core principles of advocacy, which is to empower others to achieve their full potential and exercise their rights and responsibilities. This choice is correct.

B. Subordinates are advocates for the nurse manager. This statement is false and contradicts one of the core principles of advocacy, which is to act in the best interest of those who are vulnerable or oppressed, not those who are in positions of power or authority. This choice is incorrect.

C. Advocacy encourages clients to rely on health care staff for decision-making. This statement is false and contradicts one of the core principles of advocacy, which is to respect and support clients' autonomy and self-determination, not to impose or influence their choices or actions. This choice is incorrect.

D. Nurse managers should distrust people who expose inappropriate professional practices. This statement is false and contradicts one of the core principles of advocacy, which is to promote and uphold ethical standards and quality of care, not to conceal or ignore malpractice or misconduct. This choice is incorrect.
