A client's last menstrual period was April 11. Using Naegele's rule, her estimated date of birth (EDB) would be:

Choice A Reason: This is incorrect because wearing spandex-type full-length pants can constrict the blood flow and increase the swelling in the feet. The nurse should advise the woman to wear loose-fitting clothes and comfortable shoes that do not squeeze or rub her feet.

Choice B Reason: This is correct because elevating the legs when sitting can improve venous return and reduce the swelling in the feet. The nurse should encourage the woman to elevate her legs above her heart level whenever possible and avoid crossing her legs or standing for long periods.

Choice C Reason: This is incorrect because limiting the intake of fluids can cause dehydration and worsen the swelling in the feet. The nurse should recommend the woman drink plenty of water and other healthy fluids to maintain hydration and flush out excess sodium and waste products from her body.

Choice D Reason: This is incorrect because eliminating salt from the diet can cause electrolyte imbalance and affect the fluid balance in the body. The nurse should advise the woman to consume salt in moderation and avoid processed foods that are high in sodium.

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.
