Before assisting with Leopold's maneuvers, what should the nurse ask the client to do?

Before performing Leopold's maneuvers, it's important for the nurse to ask the client to urinate. This request is based on the fact that a full bladder can displace the uterus and make it more difficult to palpate the fetus accurately. By having the client void before the procedure, the nurse helps ensure that the maneuver can be performed effectively and safely, allowing for a better assessment of fetal position and other related factors.

The other options may not adequately prepare the client for the assessment. For instance, lying down on her back without addressing a full bladder can hinder accurate palpation. While hydration is generally important, it does not specifically aid in the effectiveness of Leopold's maneuvers. Encouraging rest and relaxation can be beneficial for overall comfort, but it does not address the physical positioning of the bladder and uterus, which is crucial for the accuracy of the assessment. Therefore, asking the client to urinate is a critical step in the process.
