A nurse is teaching a client who has a new prescription for nitrofurantoin.Which of the following information should the nurse include in the teaching?

Choice A rationaleBrown-colored urine is a common side effect of nitrofurantoin and does not typically indicate a serious issue. It results from the excretion of the drug and its metabolites through the urine, which can change its color.Choice B rationaleNitrofurantoin is an antibiotic used to treat urinary tract infections. It does not provide relief for peripheral nerve pain, which is typically treated with medications such as gabapentin or pregabalin that target nerve function.Choice C rationaleNitrofurantoin tablets or capsules should not be crushed as this can affect the release mechanism of the medication. Crushing the medication may lead to rapid release and absorption, potentially causing gastrointestinal irritation.Choice D rationaleNitrofurantoin can cause pulmonary reactions, including cough, shortness of breath, and chest pain. These symptoms may indicate serious adverse effects such as pulmonary fibrosis or hypersensitivity pneumonitis, necessitating immediate medical attention.
