Correct Answer is C
Explanation
The client's symptoms are suggestive of placenta previa, which is a condition where the placenta covers part or all of the cervical opening. Placenta previa can cause painless, bright red bleeding in the third trimester, especially after sexual intercourse or a pelvic exam. The bleeding can be life-threatening for both the mother and the fetus, and the condition requires immediate evaluation and management. An ultrasound is the best diagnostic tool to confirm the location of the placenta and rule out other causes of bleeding, such as placental abruption or uterine rupture.The other options are not relevant to the client's situation and would not be indicated by an ultrasound.Fetal lung maturity is not a concern for a client who is at 38 weeks of gestation, as most fetuses have developed sufficient surfactant production by this time. Fetal lung maturity can be assessed by amniocentesis or by measuring the lecithin/sphingomyelin ratio in the amniotic fluid.Frequency and duration of contractions are not present in the client's case, as she has no signs of labor. Contractions can be monitored by external or internal tocodynamometry or by palpation.d. Rh incompatibility is a condition where the mother's blood type is Rh-negative and the fetus's blood type is Rh- positive, which can cause hemolytic disease of the newborn. Rh incompatibility can be detected by blood tests and prevented by administering Rh immunoglobulin to the mother during pregnancy and after delivery.
Correct Answer is A
Explanation
Hypertension is the most common risk factor for placental abruption, which occurs when the placenta separates from the uterine wall before delivery. Hypertension can cause damage to the blood vessels that supply the placenta, leading to reduced blood flow and increased pressure in the intervillous space. This can cause hemorrhage and detachment of the placenta.
The other options are not as common as hypertension, but they can also increase the risk of placental abruption by causing trauma, vasoconstriction, or inflammation in the placenta or uterus.
Maternal batering can cause direct injury to the abdomen or uterus, resulting in placental abruption.
Maternal cigarete smoking can cause vasoconstriction and reduced blood flow to the placenta, as well as increase the risk of thrombosis and inflammation in the placental vessels.
d. Maternal cocaine use can cause severe vasoconstriction and hypertension, which can impair placental perfusion and cause placental abruption.
