A nurse is providing teaching about nutrition to a client at her first prenatal visit.
Which of the following statements by the nurse should be included in the teaching?

Choice A rationale

The recommended time for rubella immunization for a woman who does not have immunity and is in the first trimester of pregnancy is shortly after giving birth. This is because the rubella vaccine is a live vaccine and is not recommended during pregnancy due to the potential risk to the fetus.

Choice B rationale

The rubella vaccine should not be given immediately during pregnancy due to the potential risk to the fetus.

Choice C rationale

While it’s ideal for a woman to be immune to rubella before she gets pregnant, if she finds out during pregnancy that she’s not immune, the vaccine should be given after delivery.

Choice D rationale

The rubella vaccine is not recommended during the third trimester of pregnancy due to the potential risk to the fetus.

Choice A rationale

While bile does play a role in digestion, it is not retained in the liver. Instead, it is produced by the liver and stored in the gallbladder. When food enters the small intestine, the gallbladder releases bile to aid in the digestion of fats. However, this process is not directly related to heartburn during pregnancy.

Choice B rationale

During pregnancy, the body produces large amounts of the hormones progesterone and relaxin. These hormones tend to relax smooth muscle tissues throughout the body, including those in the gastrointestinal (GI) tract. As a result, food sometimes moves more slowly through the system, resulting in indigestion issues of all kinds, from that bloated, gassy feeling to heartburn. This is the correct answer because increased progesterone production does indeed cause decreased motility of smooth muscle, which can lead to heartburn.

Choice C rationale

While estrogen levels do increase during pregnancy, they do not directly cause an increase in the secretion of hydrochloric acid. Instead, the relaxation of the lower esophageal sphincter due to pregnancy hormones can allow stomach acid to flow back up into the esophagus, causing heartburn.

Choice D rationale

While it is true that the growing uterus can displace the stomach, especially in later stages of pregnancy, this is not the primary cause of heartburn. Heartburn is primarily caused by the relaxation of the lower esophageal sphincter, allowing stomach acid to flow back up into the esophagus.
