Final answer:
The nurse would prioritize the client's concern about not taking insulin during pregnancy due to the potential risks of high blood sugar levels. It is important to address this issue promptly to ensure the well-being of both the client and the fetus.
Step-by-step explanation:
The nurse would recognize the client's concern about not taking her insulin as the priority. Insulin is crucial for managing diabetes, especially during pregnancy. If the client stops taking insulin, it can lead to dangerously high blood sugar levels, which can negatively impact both the client and the developing fetus. The nurse should address this concern immediately and emphasize the importance of continuing insulin therapy under the guidance of a healthcare provider.
