A nurse on a postpartum unit is assisting with the care of four clients. The nurse should identify that which of the following clients should receive Rh (D. immune globulin?

A. The suprapubic area is typically where the uterus can be palpated, but it's not the location for auscultating fetal heart tones at 12 weeks of gestation.

B. The umbilical area is not the optimal location at this stage; the fetal heart tones are generally not audible in this location until the uterus rises higher into the abdomen in later gestation.
C. At 12 weeks of gestation, the fetal heart tones are typically auscultated above the left iliac crest.

D. Below the liver border on the right abdomen is also not correct, as the fetal heart tones are unlikely to be found there at 12 weeks.

A. Uterine atony
Uterine atony refers to the lack of muscle tone in the uterus after delivery, leading to excessive bleeding. This is not typically associated with abruptio placentae, which involves the premature separation of the placenta from the uterine wall during pregnancy, typically presenting with different symptoms such as painful contractions and bleeding.

B. Polyhydramnios
Polyhydramnios refers to an excessive amount of amniotic fluid during pregnancy and is not a characteristic of abruptio placentae. Polyhydramnios can be associated with various conditions but is not directly linked to placental abruption.

C. Painless vaginal bleeding
Painless vaginal bleeding is more characteristic of placenta previa, a condition where the placenta is abnormally positioned over the cervix. Abruptio placentae, on the other hand, typically presents with painful vaginal bleeding due to the detachment of the placenta from the uterine wall.

D. Board-like abdomen
A board-like abdomen is a classic sign of abruptio placentae, indicating significant uterine muscle contraction and possible internal hemorrhage. The sudden separation of the placenta can cause blood to accumulate behind the placenta, leading to a rigid, "board-like" feeling of the abdomen, which is a hallmark symptom of this condition.
