What are the causes of a pressure ulcer? (Select all that apply.)

Choice A reason: Removing the nursing diagnosis in the plan of care since it has not occurred is not a good action, because it does not account for the possibility of future impairment. The client is still at risk for impaired skin integrity due to the prolonged bed rest, and the nurse should continue to monitor and prevent any skin breakdown.

Choice B reason: Keeping the nursing diagnosis in the plan of care the same since the risk factors are still present is the best action, because it reflects the current situation and the potential problem. The client has not developed impaired skin integrity, but the risk factors have not changed. The nurse should maintain the interventions that have been effective in preventing skin impairment, such as turning, repositioning, moisturizing, and inspecting the skin.

Choice C reason: Modifying the nursing diagnosis in the plan of care to impaired skin integrity is not a good action, because it does not match the data. The client has not shown any signs of impaired skin integrity, such as redness, blanching, breakdown, or ulceration. The nurse should not change the diagnosis based on assumptions or predictions, but on evidence.

Choice D reason: Changing the nursing diagnosis in the plan of care to impaired mobility is not a good action, because it does not address the original problem. The client may have impaired mobility due to the bed rest, but that is not the focus of the question. The question is about the risk for impaired skin integrity, which is a different issue that requires different interventions. The nurse should not ignore or replace the existing diagnosis without justification.

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.
