A nurse is evaluating a patient in her third trimester of pregnancy.
Which findings should the nurse recognize as expected physiological changes during pregnancy?
Gradual lordosis.
Decreased mobility of pelvic joints.
Increased abdominal muscle tone.
Posterior neck flexion.
The Correct Answer is A
Choice A rationale
Gradual lordosis, or the inward curvature of the spine, is a common physiological change during pregnancy. As the baby grows and the woman’s center of gravity shifts, the spine adjusts to maintain balance.
Choice B rationale
Decreased mobility of pelvic joints is not a typical physiological change during pregnancy. In fact, the body releases the hormone relaxin during pregnancy, which allows the ligaments in the pelvic area to relax and the joints to become looser in preparation for the birth process.
Choice C rationale
Increased abdominal muscle tone is not a typical physiological change during pregnancy. In fact, as the baby grows, the abdominal muscles stretch and can even separate, a condition known as diastasis recti.
Choice D rationale
Posterior neck flexion is not a typical physiological change during pregnancy.

Correct Answer is D
Explanation
Choice A rationale
Tubal ligation does not decrease menstrual flow. It is a surgical procedure that blocks or seals the fallopian tubes, preventing eggs from reaching the uterus for implantation.
Choice B rationale
Tubal ligation does not reduce menstrual pain. It prevents pregnancy but does not have an effect on the menstrual cycle or associated symptoms.
Choice C rationale
The timing of the procedure in relation to the menstrual cycle is not a significant factor in tubal ligation. The procedure can be performed at any time as long as pregnancy is not present.
Choice D rationale
It is crucial to emphasize that tubal ligation is considered a permanent form of birth control. While reversal procedures exist, they are not always successful and should not be relied upon. Therefore, the decision to undergo tubal ligation should be made with the understanding that it is typically irreversible.
Correct Answer is D
Explanation
Choice A rationale
Vitamin E is an important nutrient during pregnancy as it acts as an antioxidant, helping to protect cells from damage. However, its requirements do not decline during pregnancy due to an increase in body fat.
Choice B rationale
While iron is an important nutrient during pregnancy, it’s not necessary to double your intake. Iron needs do increase during pregnancy because it’s needed to make more blood to supply oxygen to the baby. However, this should be managed under the guidance of a healthcare provider.
Choice C rationale
While it’s true that calcium intake should be increased during breastfeeding, this is not specifically related to nutrition during pregnancy. During pregnancy, adequate calcium intake is important for the development of the baby’s bones and teeth.
Choice D rationale
Prenatal vitamins are designed to meet the increased nutritional needs of pregnancy, and they include a variety of vitamins and minerals. One of these is vitamin D, which helps the body absorb calcium and is important for the baby’s bone growth. Therefore, taking prenatal vitamins can indeed help to meet the need for increased vitamin D during pregnancy.
