- Which of the following is NOT true about human plague (Yersinia pestis infection)? Which option is the answer? 1. None of the other four answers (All are true about human plague) 2. Infected fleas’ gastrointestinal tract is blocked by Y. pestis growth, causing them to regurgitate and infect a new host when they bite 3. Painful swollen lymph nodes are called “buboes” 4. Usually acquired in the US from bites of fleas that have fed on infected urban rats 5. Yersinia pestis infection of lymph nodes can sometimes spread to the lungs, causing secondary pneumonic plagueA nurse is volunteering with a medical team in Southeast Asia. A 35-year-old female presents to the clinic reporting that the village doctors have diagnosed her with malaria. The nurse notes that the woman is febrile, tachypneic, and her eyes have a yellow tint. She reports generalized body aches and weakness. Through a translator, the nurse collects the woman's medical history. She reports feeling ill for about ten days, experiencing several cycles of fever, sweating, and chills that are temporarily relieved before occurring again. The village doctors treated her with a combination of a mosquito paste and an indigenous root, but her symptoms have not improved. The medical team performs serological testing at the clinic and confirms a diagnosis of malaria. 6) What is the cause of the cyclical nature of the woman's symptoms? A) She is being reinfected by a vector as she begins to recover. B) The village doctor's treatments are working intermittently. C) Her symptoms reflect the…A nurse is volunteering with a medical team in Southeast Asia.
