The nurse is teaching a patient newly diagnosed with AIDS about complications of the disease. Which of the following is the most common opportunistic infection in AIDS?
Correct Answer: A
Rationale: Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in individuals with AIDS. PCP is caused by a fungus called Pneumocystis jirovecii (formerly known as Pneumocystis carinii). Patients with AIDS have compromised immune systems, making them susceptible to opportunistic infections like PCP. This infection can be life-threatening if not treated promptly with appropriate antibiotics. Symptoms of PCP include fever, cough, and difficulty breathing. Early recognition and treatment of PCP are crucial in patients with AIDS to prevent severe complications.
