A nurse is teaching a client who is taking metronidazole. Which of the following sense alterations should the nurse include as an adverse effect of metronidazole?

A. Alterations in touch – Metronidazole is not commonly associated with tactile (touch) changes. Neuropathy can occur with prolonged use, but this is not a typical early or sensory-specific effect. B. Metallic taste – A metallic taste is a well-known and common adverse effect of metronidazole. Clients should be informed that this is unpleasant but not harmful. C. Olfactory changes – Metronidazole does not typically cause changes in the sense of smell. D. Hearing loss – Hearing loss is associated with other medications such as aminoglycosides, not metronidazole.
