What advice should a nurse give to a primigravida client regarding changes during pregnancy?

During pregnancy, a nurse should advise a primigravida client to avoid wearing high heels due to the physical changes that occur in a woman's body. As pregnancy progresses, hormonal changes lead to increased joint laxity and the softening of ligaments, which can affect balance and stability. High heels can exacerbate these challenges by increasing the risk of falls and creating additional strain on the back, which is already under stress from the growing uterus.

In contrast, wearing more supportive footwear can help maintain balance, provide greater comfort, and reduce potential back pain. This advice reflects an understanding of the biomechanical and physical changes a person experiences during pregnancy, prioritizing safety and comfort.
