Final answer:
The nurse should encourage the consumption of probiotic-rich foods, fruits high in vitamin C, nuts rich in zinc, and foods with a high water content to support the immune system and gut health while taking cephradine.
Step-by-step explanation:
When a healthcare provider prescribes the antibiotic cephradine 500mg PO every 6 hours for a client with a postoperative wound infection, the nurse should encourage foods that support the immune system and gut health. Given that antibiotics can disrupt the gut microbiome, it is beneficial to consume probiotic-rich foods like yogurt or kefir that can help maintain healthy levels of good bacteria.
Additionally, foods high in vitamin C and zinc, such as citrus fruits and nuts, may help the immune system fight off any secondary infections. Foods with a high water content, like cucumbers and watermelons, can help with rehydration and assist in preventing dehydration, a common side effect of certain antibiotics. The nurse should also remind the patient to complete the full course of prescribed antibiotics to effectively clear the infection and reduce the risk of developing antibiotic-resistant bacteria.
