TREATMENT
Given the patient’s severe lung infection and poor general condition, it is indeed appropriate to give levofloxacin to control the infection and promethazine hydrochloride to suppress the cough. Adding spironolactone and furosemide as diuretic treatments for symptom relief is also a suitable approach. This combined treatment strategy should contribute to improving the patient’s overall comfort and condition. It is important to monitor the patient closely for any changes or potential side effects from these medications.
