Final answer:
The symptoms of tuberculosis include a persistent cough that may produce mucus or blood, fatigue, weight loss, loss of appetite, night sweats, and a low-grade fever.
Step-by-step explanation:
The symptoms of tuberculosis (TB) include persistent cough, which may produce mucus or blood, fatigue, weight loss, loss of appetite, night sweats, and a low-grade fever. Patients like Marsha, who have been exposed to high-risk environments, such as medical facilities in countries with a high incidence of tuberculosis like Nigeria, can exhibit these symptoms. A low-grade fever is generally considered to be around 37.4 °C (99.3 °F), as seen in Marsha's case. Tuberculosis does not typically cause weight gain or increased appetite; in fact, weight loss and a decreased appetite are more common. Thus, the correct symptoms of tuberculosis from the options given are fatigue, low-grade fever, and potentially nausea as TB can have systemic effects that cause such symptoms.
