What should the nurse inform a client with type 1 diabetes in the first trimester regarding medication changes?

During the first trimester of pregnancy, a client with type 1 diabetes will generally require a steady increase in insulin therapy. This is because hormonal changes in pregnancy lead to alterations in insulin sensitivity and increased insulin resistance as the pregnancy progresses. While in early pregnancy, levels of hormones such as estrogen and progesterone can initially enhance insulin effectiveness, the overall need for insulin often increases as the body adapts to support fetal growth and prepare for later stages of pregnancy. This is particularly true for women with type 1 diabetes, who rely on external insulin due to their inability to produce it themselves. Thus, the statement about the need for a steady increase in insulin aligns with the physiological changes that occur during pregnancy, particularly as it progresses into the second and third trimesters.
