During the third trimester of pregnancy, which of the following findings should a nurse recognize as an expected physiologic change?

  • A. Gradual lordosis
  • B. Increased abdominal muscle tone
  • C. Posterior neck flexion
  • D. Decreased mobility of pelvic joints
Correct Answer: A

Rationale: The correct answer is A: Gradual lordosis. During the third trimester, the growing uterus shifts the center of gravity forward, leading to an increased lumbar curvature known as lordosis. This change helps maintain balance and support the extra weight. Increased abdominal muscle tone (B) is not an expected finding as abdominal muscles tend to stretch and weaken during pregnancy. Posterior neck flexion (C) is not a common physiologic change during the third trimester. Decreased mobility of pelvic joints (D) is incorrect as hormonal changes during pregnancy actually increase flexibility in the pelvic joints to prepare for childbirth.
