Maternity Nursing Q 11
A pregnant client states that she “waddles” when she walks. The nurse’s explanation is based on which of the following is the cause?
A. The large size of the newborn.
B. Pressure on the pelvic muscles.
C. Relaxation of the pelvic joints.
D. Excessive weight gain.
Correct Answer: C. Relaxation of the pelvic joints
During pregnancy, hormonal changes cause relaxation of the pelvic joints, resulting in the typical “waddling” gait. The loosening of the joints and the downward pressure from the growing belly actually cause the pelvis to get wider. A wider pelvis means a wider stance. That explains part of the waddle. The other part is caused by a shift in the center of balance.
Option A: Changes in posture are related to the growing fetus. The abdominal muscles become stretched as the baby grows. These muscles are less able to contract and keep the lower back in proper alignment. Hormone levels increase during pregnancy and cause joints and ligaments to loosen.
Option B: Pressure on the surrounding muscles causing discomfort is due to the growing uterus. The extra weight of pregnancy often becomes more noticeable in the second trimester. As pregnancy progresses, the uterus puts more and more pressure on the lower body. As the pelvic floor weakens, this pressure can cause a feeling of fullness in the vagina or generalized pain and pressure in the hips and pelvis.
Option D: Weight gain has no effect on gait. Pregnancy leads to several changes in body composition and morphology of women. It is not clear whether the biomechanical changes occurring in this period are due exclusively to body composition and size or to other physiological factors.
