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
Bleeding or spotting can accompany implantation. This is a common occurrence and does not necessarily indicate a problem with the pregnancy. It happens when the fertilized egg attaches to the lining of the uterus. Some women may mistake this bleeding for a light period, but it’s a sign of pregnancy.
Choice B rationale
Fertilization typically takes place in the outer third of the fallopian tube. After ovulation, the egg travels down the fallopian tube towards the uterus. If sperm are present in the fallopian tube at this time, fertilization can occur. This is a normal part of the reproductive process.
Choice C rationale
Sperm can remain viable in the woman’s reproductive tract for 2 to 3 days. This means that intercourse does not have to coincide exactly with ovulation in order to achieve pregnancy. The sperm can survive long enough to fertilize the egg when it is released.
Choice D rationale
The statement “Implantation occurs between 2 and 3 weeks after conception” is incorrect and requires intervention by the nurse. Implantation actually occurs about 6-10 days after ovulation, which is less than 2 weeks after conception.
Correct Answer is A
Explanation
Choice A rationale
High-absorbency tampons are a known risk factor for toxic shock syndrome (TSS). TSS is a rare, life-threatening complication of certain types of bacterial infections. Often TSS results from toxins produced by Staphylococcus aureus (staph) bacteria, but the condition may also be caused by toxins produced by group A streptococcus (strep) bacteria. The condition is caused due to bacterial toxins from Streptococcus or Staphylococcus infection. Bacteria usually enter the body through openings in the skin such as wounds or cuts. The risk factors include open skin wound, having had recent surgery, using superabsorbent tampons or contraceptive sponges. Therefore, the nurse should include the use of high-absorbency tampons in the teaching as increasing the risk for contracting TSS.
Choice B rationale
Travel to foreign countries is not specifically mentioned as a risk factor for TSS. While traveling can expose individuals to a variety of health risks depending on the destination, it is not directly linked with an increased risk of TSS1234.
Choice C rationale
Mosquito bites are not a known risk factor for TSS. Mosquito bites can transmit certain diseases such as malaria, dengue fever, and Zika virus, but they are not associated with TSS1234.
Choice D rationale
Having multiple sexual partners can increase the risk of sexually transmitted infections, but it is not a known risk factor for TSS. TSS is typically associated with superabsorbent tampon use, skin wounds, and recent surgery.
