Which statement indicates a client's understanding of how to relieve discomfort during pregnancy?

The statement indicating a client's understanding of how to relieve discomfort during pregnancy is one that emphasizes proper positioning and rest. Lying on the floor with legs elevated and hips at right angles can help alleviate pressure and improve circulation, which is particularly beneficial for relieving discomfort associated with pregnancy, such as back pain and swelling in the legs. This position can aid in venous return and reduce the strain on the lower back, providing a valuable technique for managing discomfort.

The other statements suggest approaches that may not be ideal for relieving discomfort in all circumstances. Standing for extended periods can exacerbate fatigue and discomfort, while the regular use of a heating pad may not be recommended without specific guidance from a healthcare provider, especially during pregnancy when overheating can be a concern. Lastly, the belief that yoga is not beneficial during the second trimester reflects a misunderstanding, as many types of gentle yoga can be very beneficial during pregnancy when practiced safely.
