Final answer:
An appropriate question for assessing side effects of methylprostaglandin postpartum would be about the occurrence of diarrhea, as it is a known side effect of prostaglandin analogs.
Step-by-step explanation:
The nurse is conducting a follow-up assessment for a client who received methylprostaglandin postpartum. This medication is commonly used to manage postpartum hemorrhage by causing the uterus to contract and reduce bleeding. When assessing the client for side effects of methylprostaglandin, an appropriate question the nurse might ask is, "Have you experienced any diarrhea?" Diarrhea is a known side effect of prostaglandin analogs, which includes methylprostaglandin.
While questions about decreased bleeding and breast engorgement are also relevant to postpartum care, they are not directly associated with the side effects of methylprostaglandin. Pain is a broad symptom and could be related to various aspects of postpartum recovery, but diarrhea is more specific to the medication's side effects.
