A third-trimester pregnant client reports that her shoes no longer fit comfortably. She asks if it's normal for her feet to feel larger. Which of the following is the nurse's best response?

"It's normal for feet to increase in size during pregnancy due to ligament relaxation and arch flattening, and the change may be permanent."

"It's uncommon, but you may have developed a foot infection that's causing swelling and enlargement."

This is likely due to calcium loss from the bones, which can cause foot deformities during pregnancy."

"This may indicate poor fetal growth and should be reported to your provider immediately."
