Which statement indicates that a client with type 1 diabetes mellitus needs further teaching regarding insulin changes during pregnancy?

The statement indicating that a client with type 1 diabetes mellitus needs further teaching regarding insulin changes during pregnancy is the one that mentions needing to increase insulin dosage during the first three months of pregnancy. This is correct because, during the first trimester, many women with type 1 diabetes experience lower insulin requirements due to physiological changes, such as decreased insulin resistance and changes in hormone levels.

However, as pregnancy progresses into the second and third trimesters, there is typically an increased insulin requirement due to rising insulin resistance as the placenta grows. Therefore, the need for increased insulin dosage is often more characteristic of later pregnancy rather than the initial stages. Proper management and understanding of these changes are crucial for maintaining optimal blood glucose levels and ensuring the health of both the mother and the fetus.

Monitoring blood sugar levels regularly, adjusting insulin as needed later in pregnancy, and consulting with a healthcare provider about insulin needs are all appropriate statements reflecting a good understanding of diabetes management during pregnancy.
