Final answer:
The most important question a prenatal nurse should ask a pregnant client with Type 1 Diabetes Mellitus experiencing nausea is regarding the regular monitoring of their blood glucose levels, as nausea can significantly affect diabetic control, especially during pregnancy.
Step-by-step explanation:
When a prenatal nurse visits a pregnant client diagnosed with Type 1 Diabetes Mellitus (DM I) where the client reports nausea, the nurse's priority should be to assess the impact of nausea on her glucose control. Therefore, the most important question to ask the client would be:
"Have you been monitoring your
blood glucose levels
regularly?"
Nausea can lead to decreased intake of food, which can significantly affect blood glucose levels and insulin requirements. Regular monitoring is crucial in diabetes management, and it becomes even more essential during pregnancy due to the changing physiological needs and the increased risk of hypoglycemia or ketoacidosis.
