The nurse is providing discharge instructions for a client with metastatic cancer who is proscribed morphine for bone pain. Which information from the client indicates to the nurse an understanding of the medication?

A) Take the benzodiazepine at the same time of taking the morphine: This statement is incorrect. Benzodiazepines and morphine are both central nervous system depressants and can potentiate each other’s effects, leading to increased sedation and respiratory depression. Taking them together without proper supervision or dosage adjustment can be dangerous. Therefore, this statement indicates a misunderstanding of the medication regimen. B) Do not drink grapefruit juice after taking morphine: While grapefruit juice can interact with certain medications by affecting their metabolism, there is no specific interaction between grapefruit juice and morphine that requires avoidance. Therefore, this statement is not directly related to the use of morphine for bone pain. C) Watch for signs of agitation and record any insomnia: While it is important to monitor for side effects of morphine, such as agitation and insomnia, this statement does not directly relate to the management of constipation, which is a common side effect of opioid analgesics like morphine. D) Observe bowel movement pattern and take a stool softener: This is the correct answer. Morphine is known to cause constipation as a side effect due to its action on opioid receptors in the gastrointestinal tract. Therefore, monitoring bowel movements and taking a stool softener can help prevent or alleviate constipation associated with morphine use. This statement indicates an understanding of the potential side effects of the medication and the importance of managing them appropriately.
