Registered Nurse (RN) Respiratory Practice Exam

The statement indicating a possible adverse effect of Vancomycin that requires immediate medical attention is the one expressing a constant ringing in the ears. This symptom is known as tinnitus and is notably associated with ototoxicity, which is a serious side effect of Vancomycin, especially at higher doses or with prolonged use. Ototoxicity can lead to irreversible hearing loss, making it imperative that any patient reporting such symptoms receives prompt evaluation and intervention to potentially mitigate further damage.

Additionally, while other side effects, such as altered taste or headaches, may occur, they do not typically indicate a severe or life-threatening reaction that necessitates immediate medical attention. Yellow halos around lights may pertain more to visual disturbances and could signal other issues, but they are not specifically linked to Vancomycin. Understanding these effects and recognizing the urgency of signs like tinnitus is crucial for ensuring patient safety and effective management of potential complications.
