What are opportunistic infections associated with acquired immunodeficiency syndrome (AIDS)? (Select all that apply.)

Choice A reason: "I will take all prescribed medications." is not a statement that demonstrates an understanding of the teaching, because it is incomplete and vague. Taking all prescribed medications is an important part of the treatment for HIV, but it does not explain why, how, or for how long the medications are needed. Taking all prescribed medications without understanding the purpose, benefits, or risks can lead to poor adherence, compliance, or outcomes.

Choice B reason: "I will only need to take HIV medications for 6 months, and then I will be cured." is not a statement that demonstrates an understanding of the teaching, because it is incorrect and unrealistic. Taking HIV medications for 6 months is not enough to treat the infection, and there is no cure for HIV. HIV is a chronic and incurable infection that requires lifelong treatment with antiretroviral drugs, which can suppress the viral load, improve the immune function, and prevent the progression to AIDS. Stopping the medications after 6 months can cause the virus to rebound, the immune system to deteriorate, and the disease to worsen.

Choice C reason: "I will have to take medications for the rest of my life." is a statement that demonstrates an understanding of the teaching, because it is accurate and realistic. Taking medications for the rest of one's life is the reality of living with HIV, as there is no cure for the infection. Taking medications for the rest of one's life can help control the infection, maintain the health, and prolong the survival of people with HIV.

Choice D reason: "I will have to be careful and avoid crowds." is not a statement that demonstrates an understanding of the teaching, because it is unnecessary and exaggerated. Being careful and avoiding crowds is not a requirement for people with HIV, as the infection is not transmitted by casual contact, such as touching, hugging, or sharing utensils. Being careful and avoiding crowds can also be detrimental to the social and emotional wellbeing of people with HIV, as it can cause isolation, stigma, or depression.

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.
