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. Use the arms to pick up heavy items. Lifting heavy objects using only the arms increases strain on the back, worsening pain. Pregnant clients should bend at the knees and lift with their legs while keeping the back straight to reduce stress on the lumbar region. B. Raise chairs to keep knees lower than hips. Sitting with knees lower than the hips can worsen lumbar lordosis, increasing back discomfort. Instead, knees should be at or slightly above hip level to maintain spinal alignment and reduce strain on the lower back. C. Perform pelvic rocking exercises several times per day. Pelvic rocking strengthens and stretches lower back muscles, improving flexibility and reducing discomfort. This exercise helps alleviate strain from the growing uterus and supports better posture, decreasing back pain. D. Sit in a hot tub for 30 min every evening. Prolonged exposure to high temperatures, such as in a hot tub, can cause maternal hyperthermia, increasing the risk of fetal neural tube defects. Warm baths are a safer option to relieve muscle tension without harmful effects.
