Nursing Test Bank Physiological And Physical Changes In Pregnancy Latest Update 2024

A nurse is assessing a pregnant client who complains of lower back pain. Which musculoskeletal change during pregnancy is primarily responsible for this symptom? A. Increased joint laxity.B. Increased spinal curvature.C. Increased muscle strain.D. Decreased muscle strength. Explanation This is because the growing uterus shifts the center of gravity and causes an increased strain on the back muscles and ligaments. This can lead to lower back pain during pregnancy. Choice A is wrong because increased joint laxity is caused by hormonal changes during pregnancy, not by musculoskeletal changes. Joint laxity can affect the stability of the joints, but not necessarily cause lower back pain. Choice C is wrong because increased muscle strain is a result of increased spinal curvature, not a cause of it. Muscle strain can also contribute to lower back pain, but it is not the primary musculoskeletal change during pregnancy. Choice D is wrong because decreased muscle strength is not a musculoskeletal change during pregnancy, but a possible consequence of reduced physical activity or poor posture. Muscle strength can affect the support of the spine, but it is not the main factor for lower back pain. Normal ranges for spinal curvature vary depending on age, sex, and posture, but generally the lumbar lordosis (the inward curve of the lower spine) should be between 20 and
