59 Changes Of The Skeletal System During Pregnancy

a. There is a realignment of the spinal curvatures during pregnancy to maintain balance (see figure 5-3). It is due to the increase in size of the uterus and pressure on the abdominal wall. The patient walks with head and shoulders thrust backward and chest protruding outward to compensate. This gives the patient a "waddling" gait.

b. There is a slight relaxation and increased mobility of the pelvic joints, which allows stretching at the time of delivery of the infant.

a. As mentioned in paragraph 5-1, as the pregnancy progresses, the uterus enlarges. It rises up and out of the pelvic cavity. This action displaces the stomach, intestines, and other adjacent organs.

b. Peristalsis is slowed because of the production of the hormone progesterone, which decreases tone and mobility of smooth muscles. This slowing enhances the absorption of nutrients and slows the rate of secretion of hydrochloric acid and pepsin. Flare-up of peptic ulcers is uncommon in pregnancy. Slow emptying may increase nausea and heartburn (pyrosis). Relaxation of the cardiac sphincter may increase regurgitation and chance for heartburn. Movement through the large intestines is also slowed due to an increase in water consumption from this area. This increases the chance for constipation.

c. Nursing implications.

(1) If the mother has difficulty with nausea and/or heartburn, advise her to eat small, frequent meals.

(2) The patient should eat a well- balanced diet high in protein, iron, and calcium for fetal growth; high fiber and fluids to prevent constipation.

(3) The mother should not lie flat for 1 to 2 hours after eating because this may cause heartburn and/or regurgitation.
