A pregnant woman in the 36th week of gestation reports that her feet are quite swollen at the end of the day. After careful assessment, the nurse determines that this is an expected finding at this stage of pregnancy. Which intervention is appropriate for the nurse to suggest?

Choice A Reason: Preeclampsia is a condition in which a pregnant woman develops high blood pressure and proteinuria (protein in the urine). It can lead to serious complications such as eclampsia, which is seizures caused by preeclampsia, and HELLP syndrome, which is hemolysis, elevated liver enzymes, and low platelets. The main risk factor for preeclampsia is chronic hypertension, which means high blood pressure before pregnancy or before 20 weeks of gestation. Preeclampsia can be detected by measuring the blood pressure and urine protein level. Uric acid is not a reliable indicator of preeclampsia.

Choice B Reason: Gestational diabetes is the correct answer as explained above.

Choice C Reason: Eclampsia is a severe complication of preeclampsia that causes seizures and can be fatal for both the mother and the baby. It usually occurs after 20 weeks of gestation or during labor or postpartum. The main risk factor for eclampsia is preeclampsia, which means high blood pressure and proteinuria during pregnancy. Eclampsia can be prevented by treating preeclampsia with antihypertensive drugs and magnesium sulfate, which is a medication that prevents seizures. Magnesium sulfate can also lower the serum magnesium level, which is the amount of magnesium in the blood. However, magnesium level is not a diagnostic criterion for eclampsia.

Choice D Reason: Placenta previa is a condition in which the placenta covers part or all of the opening of the cervix. It can cause bleeding during pregnancy or delivery and can endanger both the mother and the baby. The main risk factor for placenta previa is previous cesarean section or other uterine surgery, which can cause scarring or damage to the uterine wall. Placenta previa can be detected by ultrasound, which is an imaging test that uses sound waves to create pictures of the uterus and placenta. Hemoglobin is not a relevant factor for placenta previa. Gestational diabetes is a condition in which a woman develops high blood sugar levels during pregnancy. It can cause complications for both the mother and the baby, such as macrosomia, hypoglycemia, and birth trauma. The main risk factor for gestational diabetes is glucose intolerance, which means the body cannot use glucose effectively. Glucose intolerance can be detected by measuring the serum glucose level, which is the amount of glucose in the blood.

Choice A Reason: This is incorrect because ultrasound visualization of the fetus is a positive sign of pregnancy, not a probable sign. A positive sign of pregnancy is a direct and definitive evidence of the presence of a fetus, such as fetal movement felt by the examiner or fetal heart sounds heard by a Doppler device.

Choice B Reason: This is correct because softening of the cervix, also known as Goodell's sign, is a probable sign of pregnancy. A probable sign of pregnancy is a strong indication of pregnancy based on physical changes in the reproductive organs, such as enlargement of the uterus or changes in the shape and consistency of the cervix.

Choice C Reason: This is correct because a positive pregnancy test, which detects human chorionic gonadotropin (hCG) in urine or blood, is a probable sign of pregnancy. However, it is not a conclusive sign, as hCG can also be produced by other conditions such as ectopic pregnancy, molar pregnancy, or trophoblastic tumors.

Choice D Reason: This is correct because absence of menstruation, also known as amenorrhea, is a probable sign of pregnancy. It occurs when ovulation and menstruation cease due to hormonal changes during pregnancy. However, it is not a definitive sign, as amenorrhea can also be caused by other factors such as stress, illness, or hormonal imbalances.

Choice E Reason: This is correct because ballottement, which is a rebounding of the fetus against the examiner's fingers during a pelvic examination, is a probable sign of pregnancy. It can be felt around 16 to 20 weeks of gestation.

Choice F Reason: This is incorrect because auscultation of a fetal heart beat, which can be heard by a fetoscope around 18 to 20 weeks of gestation or by a Doppler device around 10 to 12 weeks of gestation, is a positive sign of pregnancy, not a probable sign.
