A nurse is reinforcing dietary teaching with an adolescent who is at 10 weeks of gestation.
Which of the following statements should the nurse make?

- A: The formula infusion rate being too slow typically does not cause diarrhea; instead, it could lead to inadequate nutritional intake.
- B: Administering formula that is too cold can cause diarrhea because the cold temperature can stimulate gastrointestinal motility, leading to increased bowel movements.
- C: A partially obstructed feeding tube is more likely to cause reduced or stopped flow of the formula, potentially leading to inadequate nutrition, rather than diarrhea.
- D: Delayed gastric emptying would typically cause symptoms such as nausea and vomiting, not diarrhea. Diarrhea is more likely when substances pass too quickly through the digestive system.

- Choice A Rationale: The epidural PCA (patient-controlled analgesia) is designed with safety mechanisms to ensure that the patient cannot administer a dose that exceeds the prescribed safe limit. This is crucial to prevent potential overdose and complications associated with high doses of analgesics.
- Choice B Rationale: While it is true that some patients may experience reduced mobility in their legs during epidural analgesia, this is not an absolute and can vary based on the dosage and individual response. Therefore, it is not a guaranteed effect and should not be presented as such.
- Choice C Rationale: There is no conclusive evidence to suggest that epidural pain control methods shorten the second stage of labor. In fact, some studies indicate that it may actually prolong it. The primary purpose of epidural PCA is pain management, not altering the labor process timeline.
- Choice D Rationale: Postpartum headaches can be a side effect of epidural anesthesia, but they are not common to all cases. It is associated with a complication known as a post-dural puncture headache, which occurs in a minority of cases. Hence, it should not be stated as a common outcome.
