A nurse is assisting in the care of a client who is at 34 weeks of gestation and is experiencing lower back pain. Which of the following recommendations should the nurse make?

A) Sit in a hot tub for 30 min every evening: While a warm bath or hot tub may provide temporary relief for some types of pain, it is not generally recommended during pregnancy, especially in the later stages, because prolonged exposure to hot water can raise the body's core temperature. This could pose a risk to both the mother and fetus, especially at 34 weeks of gestation. It is safer to use warm compresses or baths for shorter durations. B) Raise chairs to keep knees lower than hips: This recommendation is incorrect. For relieving lower back pain, it is better for the knees to be slightly higher than the hips when sitting. This posture helps to alleviate strain on the lower back by reducing pressure on the spine. Sitting with the knees lower than the hips can actually exacerbate lower back pain. C) Perform pelvic rocking exercises several times per day: Pelvic rocking exercises are an excellent recommendation for relieving lower back pain during pregnancy. These exercises involve gently rocking the pelvis forward and backward, which can help to strengthen the lower back muscles, relieve tension, and improve posture. They are specifically beneficial in alleviating discomfort during pregnancy, particularly at 34 weeks of gestation. D) Use the arms to pick up heavy items: While using the arms instead of the back is generally a good practice for avoiding strain, this advice does not directly address the specific issue of lower back pain during pregnancy. Pregnant clients should be advised to avoid lifting heavy objects whenever possible, as the added weight can exacerbate back pain. Safe body mechanics, such as squatting down to pick up objects and using leg muscles rather than back muscles, are also important.
