A nurse is educating a pregnant client about the endocrine changes during pregnancy.

Which hormone is responsible for inhibiting ovulation and stimulating milk production?

This is because cramping and vaginal bleeding 24 hours after amniocentesis are signs of possible complications, such as injury to the baby or mother, leaking of amniotic fluid, infection, Rh sensitization, preterm labor, or miscarriage.

These complications are rare, but they can be serious and require immediate medical attention.

Choice B is wrong because administering pain medication to the patient does not address the underlying cause of the cramping and bleeding, and may delay seeking help.

Choice C is wrong because encouraging the patient to rest and elevate her legs may not prevent further complications, and may also delay seeking help.

Choice D is wrong because offering emotional support and reassurance to the patient is not enough to ensure the safety of the baby and the mother, and may give a false sense of security.

Normal ranges for amniocentesis are:

No chromosomal defects detected in the fetus and no abnormal proteins present in amniotic fluid

No signs of infection or other illness in the baby

Fetal lungs mature enough for birth if delivery is planned sooner than 39 weeks

Peristalsis and uterine contractility would increase.

This is because progesterone is a hormone that relaxes the smooth muscles of the uterus and the gastrointestinal tract during pregnancy.

If progesterone were reduced or withdrawn, the uterus would contract more and peristalsis would increase, leading to possible preterm labor and digestive problems.

Choice A is wrong because insulin resistance would be decreased, not increased, by lower progesterone levels.

Progesterone increases insulin resistance during pregnancy to ensure adequate glucose supply for the fetus.

Choice B is wrong because sweat and sebaceous glands would decrease production, not increase, by lower progesterone levels.

Progesterone stimulates the activity of these glands during pregnancy to regulate body temperature and protect the skin from infections.

Choice C is wrong because pyrosis (heartburn) would decrease in frequency, not increase, by lower progesterone levels.

Progesterone relaxes the lower esophageal sphincter during pregnancy, allowing gastric acid to reflux into the esophagus and cause pyrosis.
