Correct Answer: D

Rationale: Abruptio placentae is the premature separation of the placenta from the uterine wall, which can cause continuous abdominal pain and vaginal bleeding. In this scenario, the client's symptoms of sudden abdominal pain and vaginal bleeding are indicative of abruptio placentae, which requires immediate medical attention to prevent potential complications for both the client and the fetus. Placenta previa is characterized by painless vaginal bleeding in the third trimester, not sudden abdominal pain. Prolapsed cord presents with visible umbilical cord protruding from the vagina and is not associated with abruptio placentae symptoms. Incompetent cervix typically manifests as painless cervical dilation in the second trimester, not sudden abdominal pain and bleeding as seen in abruptio placentae.

Correct Answer: C

Rationale: The correct answer is C: "Breech." The RSA position indicates that the fetus is in a breech presentation. In a breech presentation, the buttocks or feet are positioned to be delivered first, which can impact the mode of delivery and require close monitoring during labor and birth. Choice A (Vertex) refers to the head-first presentation, which is considered the normal and most common presentation for birth. Choice B (Shoulder) does not represent a specific fetal presentation. Choice D (Mentum) refers to the chin presentation, which is also not relevant in this scenario.

Correct Answer: A

Rationale: The yellow skin observed in the newborn suggests jaundice. Maternal/newborn blood group incompatibility is a common cause of jaundice in newborns. This occurs when the mother and baby have different blood types, leading to the baby's immune system attacking the red blood cells, causing jaundice. Physiologic jaundice, which is a normal process due to the breakdown of red blood cells in newborns, typically presents after the first 24 hours of life. Absence of vitamin K leads to bleeding issues, not jaundice. Maternal cocaine abuse does not directly cause jaundice in newborns.

Correct Answer: D

Rationale: The correct answer is D. In a persistent occiput posterior position, the baby's head presses against the mother's spine, causing prolonged labor and severe backache. This position can lead to difficulties in labor progress and increase discomfort for the mother. Choices A, B, and C are incorrect as they do not directly relate to the client's difficult, prolonged labor with severe backache. Fetal attitude, fetal lie, and maternal pelvis type may affect labor, but in this scenario, the persistent occiput posterior fetal position is the primary contributing cause for the client's symptoms.
