A nurse is caring for a client who is at 22 weeks of gestation and has been unable to control her gestational diabetes mellitus with diet and exercise. The nurse should anticipate a prescription from the provider for which of the following medications for the client?

Choice A reason: Asymmetric thigh folds is a common finding in newborns who have DDH, because the affected hip is dislocated or subluxated, causing the thigh to appear shorter and the skin folds to be uneven. The nurse should compare the number and depth of the skin folds on both sides of the groin and buttocks.

Choice B reason: Absent plantar reflexes is not a typical finding in newborns who have DDH, because it is not related to the hip joint. The plantar reflex is a normal reflex that causes the toes to curl when the sole of the foot is stroked. The nurse should assess the plantar reflex in all newborns, regardless of their hip status.

Choice C reason: Lengthened thigh on the affected side is not a usual finding in newborns who have DDH, because the opposite is true. The affected thigh is usually shorter than the unaffected thigh, due to the displacement of the femoral head from the acetabulum. The nurse should measure the length of both thighs from the anterior superior iliac spine to the medial malleolus.

Choice D reason: Inwardly turned foot on the affected side is not a specific finding in newborns who have DDH, because it can be caused by other conditions, such as metatarsus adductus or clubfoot. The inward turning of the foot is not a direct result of the hip disorder, but rather a secondary effect of the abnormal positioning of the leg. The nurse should examine the alignment and mobility of the foot and ankle.

Choice A reason: This statement is correct, as the ultrasound can help diagnose placenta previa, which is a condition where the placenta covers the cervical opening and can cause painless, bright red bleeding in the third trimester. Placenta previa is a serious complication that can affect the delivery and the fetal oxygenation.

Choice B reason: This statement is incorrect, as the biparietal diameter is a measurement of the fetal head that is used to estimate the gestational age and the fetal growth. The biparietal diameter is not related to the cause or the severity of the bleeding.

Choice C reason: This statement is incorrect, as the fetal lung maturity is an assessment of the surfactant level in the amniotic fluid that is used to predict the risk of respiratory distress syndrome in preterm infants. The fetal lung maturity is not related to the cause or the severity of the bleeding.

Choice D reason: This statement is incorrect, as the viability of the fetus is an evaluation of the fetal heart rate, movement, and tone that is used to determine the fetal well-being and distress. The viability of the fetus is not related to the cause or the severity of the bleeding, although it can be affected by it.
