A nurse is assessing a client who is in the third trimester of pregnancy. The nurse should recognize which of the following findings as an expected physiologic change during pregnancy?

Posterior neck flexion

Increased abdominal muscle tone

Gradual lordosis

Decreased mobility of pelvic joints

Answer and Explanation

The Correct Answer is C

Choice A: Posterior neck flexion is not an expected change during pregnancy.

Choice B: Increased abdominal muscle tone is not an expected change during pregnancy. In fact, the abdominal muscles tend to stretch and may become less toned as the uterus expands.

Choice C: During pregnancy, the woman's center of gravity shifts due to the growing uterus, leading to an increased arch in the lower back known as lordosis. This change helps to maintain balance and reduce the strain on the back. The other options are not expected physiologic changes during pregnancy.

Choice D: Decreased mobility of pelvic joints is not an expected change during pregnancy. Some joint laxity may occur due to hormonal changes, but decreased mobility is not typical.

Correct Answer is A

Explanation

Choice A: The client's symptoms of lightheadedness and tingling fingers indicate that she may be hyperventilating, which can occur when patternpaced breathing is too rapid. Breathing into a paper bag can help the client rebreathe some of the exhaled carbon dioxide, which can help correct the respiratory alkalosis caused by hyperventilation.

Choice B: Administering oxygen via nasal cannula may not address the underlying issue of hyperventilation. It is more appropriate to assist the client in slowing down her breathing pattern.

Choice C: Tucking the chin to the chest is not relevant to the client's symptoms of hyperventilation.

Choice D: Instructing the client to increase her respiratory rate would exacerbate the hyperventilation, leading to more symptoms of respiratory alkalosis.

A. "The child might develop encephalitis, a complication of rubella." B. "Exposure to rubella will suppress the newborn's immune response." C. "The newborn is at risk for developing a TORCH infection." D. "The newborn might be actively shedding the virus."

Correct Answer is D

Explanation

Choice A: While rubella can lead to complications like encephalitis, this answer does not address the reason for isolation precautions for the newborn.

Choice B: While rubella can suppress the immune response in general, it does not explain the need for isolation of the newborn specifically.

Choice C: TORCH (Toxoplasmosis, Rubella, Cytomegalovirus, and Herpes) infections are a group of infections that can be transmitted from mother to fetus during pregnancy. While rubella is part of the TORCH infections, this answer does not specifically address the reason for isolation of the newborn after delivery.

Choice D: Rubella, also known as German measles, is a contagious viral infection. Newborns born to mothers with rubella can be at risk because the virus can be transmitted to them during delivery. The newborn might be actively shedding the virus, which is why isolation precautions are necessary to prevent the spread of the infection to other vulnerable newborns or individuals.
