A nurse is assisting with the admission of a client to the postpartum unit and is reviewing the client's prescribed medications. The nurse should clarify which of the following prescriptions with the provider?

A. Ibuprofen 600 mg PO every 6 hr PRN for moderate pain. This is an appropriate nonsteroidal anti-inflammatory drug (NSAID) commonly used for postpartum pain relief. B. Oxycodone 5 mg PO every 4 hr PRN for severe pain. This opioid analgesic is commonly prescribed for severe postpartum pain and is appropriate when used cautiously. C. Calcium carbonate 750 mg PO. This prescription requires clarification because calcium carbonate is typically used as an antacid or calcium supplement, but its indication is unclear in a postpartum client. The provider should confirm whether the client has a calcium deficiency, osteoporosis, or gastroesophageal reflux disease (GERD) requiring this medication. D. Bisacodyl 10 mg rectal now. This is an appropriate stimulant laxative often used postpartum to prevent constipation, especially if the client has limited mobility or opioid-induced constipation.
