The patient complains of fatigue and joint pain and reports that they are unable to walk due to pain in the knees. What is the most appropriate statement by the nurse?

Choice A reason: This is an incorrect answer because Medicare is a federal health insurance program that covers certain groups of people, such as the elderly, the disabled, and the lowincome. Medicare does not publish the National Patient Safety Goals, but it does have its own quality and safety standards that health care providers must meet to receive reimbursement.

Choice B reason: This is an incorrect answer because the American Nurses Association (ANA) is a professional organization that represents the interests of registered nurses in the United States. The ANA does not publish the National Patient Safety Goals, but it does have its own code of ethics, standards of practice, and policies that guide nursing practice and promote quality and safety.

Choice C reason: This is the correct answer because the Joint Commission is an independent, nonprofit organization that accredits and certifies more than 22,000 health care organizations and programs in the United States. The Joint Commission publishes the National Patient Safety Goals, which are specific and measurable goals that address the most critical patient safety issues in health care. The Joint Commission updates the goals annually based on the latest evidence and expert input.

Choice D reason: This is an incorrect answer because the Institute of Medicine (IOM) is a division of the National Academies of Sciences, Engineering, and Medicine, which is a private, nonprofit organization that provides independent, objective, and authoritative advice to inform policy and practice. The IOM does not publish the National Patient Safety Goals, but it does conduct research and issue reports on various topics related to health and health care, including quality and safety.

Choice A reason: This is an incorrect answer because a pathogenic infection is caused by a microorganism that can cause disease in a healthy host. Pathogens are usually able to overcome the host's immune defenses and cause symptoms and damage. Examples of pathogenic infections are strep throat, tuberculosis, and malaria.

Choice B reason: This is the correct answer because an opportunistic infection is caused by a microorganism that normally does not cause disease in a healthy host, but can take advantage of a weakened immune system and cause serious illness. Opportunistic infections are common and often lifethreatening complications of HIV infection, as the virus destroys the CD4 cells that help fight infections. Examples of opportunistic infections are pneumocystis pneumonia, candidiasis, and toxoplasmosis.

Choice C reason: This is an incorrect answer because a nosocomial infection is acquired in a health care setting, such as a hospital, clinic, or nursing home. Nosocomial infections are usually caused by microorganisms that are resistant to antibiotics and can spread easily among patients and staff. Examples of nosocomial infections are methicillinresistant Staphylococcus aureus (MRSA), Clostridioides difficile (C. diff), and urinary tract infections.

Choice D reason: This is an incorrect answer because a root cause infection is not a valid term in medical terminology. A root cause is the underlying factor or reason that leads to a problem or outcome. A root cause analysis is a process of identifying and addressing the root causes of a problem or event, such as an infection, to prevent recurrence and improve quality and safety.
