Before applying a cord clamp, the nurse assesses the umbilical cord for vessels. The nurse expects to find: Select one:
Two arteries, one vein.
Two veins, one artery.
Two veins, two arteries.
One artery, one vein.
The Correct Answer is A
Choice A Reason: Two arteries, one vein. This is because two arteries and one vein are the normal components of the umbilical cord, which is a structure that connects the fetus to the placenta and provides blood circulation between them. The umbilical cord carries oxygenated blood from the placenta to the fetus through the umbilical vein, and deoxygenated blood from the fetus to the placenta through the umbilical arteries.
Choice B Reason: Two veins, one artery. This is an incorrect answer that indicates an abnormal anatomy of the umbilical cord, which is known as single umbilical artery (SUA). SUA is a condition where there is only one umbilical artery instead of two, which can reduce blood flow and oxygen delivery to the fetus. SUA can be associated with congenital anomalies or growth restriction in some cases.
Choice C Reason: Two veins, two arteries. This is an incorrect answer that indicates an abnormal anatomy of the umbilical cord, which is known as double umbilical vein (DUV). DUV is a condition where there are two umbilical veins instead of one, which can increase blood flow and oxygen delivery to the fetus. DUV can be associated with fetal overgrowth or polycythemia in some cases.
Choice D Reason: One artery, one vein. This is an incorrect answer that indicates an abnormal anatomy of the umbilical cord, which is also known as single umbilical artery (SUA). SUA is a condition where there is only one umbilical artery instead of two, which can reduce blood flow and oxygen delivery to the fetus. SUA can be associated with congenital anomalies or growth restriction in some cases.

Correct Answer is A
Explanation
Choice A Reason: Inspecting the placenta after delivery for intactness. This is because inspecting the placenta after delivery for intactness is a nursing intervention that can prevent late postpartum hemorrhage, which is excessive bleeding from the uterus or genital tract that occurs more than 24 hours but less than 12 weeks after delivery. Late postpartum hemorrhage can be caused by retained placental fragments, subinvolution of the uterus, infection, or coagulation disorders. Inspecting the placenta after delivery for intactness can help identify and remove any retained placental fragments that may interfere with uterine contraction and involution, which are essential for hemostasis.
Choice B Reason: Manually removing the placenta at delivery. This is an incorrect answer that indicates an inappropriate and risky intervention that can cause late postpartum hemorrhage. Manually removing the placenta at delivery is a procedure that involves inserting a hand into the uterus and detaching the placenta from the uterine wall. Manually removing the placenta at delivery is indicated only for a retained or adherent placenta that does not separate spontaneously or with gentle traction within 30 minutes after delivery. Manually removing the placenta at delivery can cause trauma, infection, or incomplete removal of the placenta, which can increase the risk of late postpartum hemorrhage.
Choice C Reason: Administering broad-spectrum antibiotics prophylactically. This is an incorrect answer that suggests an unnecessary and ineffective intervention that can prevent late postpartum hemorrhage. Administering broad- spectrum antibiotics prophylactically is a pharmacological intervention that involves giving antibiotics to prevent or treat infection. Administering broad-spectrum antibiotics prophylactically is indicated for women with risk factors or signs of infection during or after delivery, such as prolonged rupture of membranes, chorioamnionitis, fever, or foul- smelling lochia. Administering broad-spectrum antibiotics prophylactically may reduce the risk of infection-related late postpartum hemorrhage, but it does not address other causes of late postpartum hemorrhage such as retained placental fragments or subinvolution of the uterus.
Choice D Reason: Applying traction on the umbilical cord to speed up separation of the placenta. This is an incorrect answer that refers to a different intervention that can prevent early postpartum hemorrhage, not late postpartum hemorrhage. Applying traction on the umbilical cord to speed up separation of the placenta is a technique that involves pulling on the umbilical cord while applying counter pressure on the uterus to facilitate placental expulsion. Applying traction on the umbilical cord to speed up separation of the placenta is indicated for active management of the third stage of labor, which can prevent early postpartum hemorrhage, which is excessive bleeding from the uterus or genital tract that occurs within 24 hours after delivery. Early postpartum hemorrhage can be caused by uterine atony, retained placenta, lacerations, or coagulation disorders.
Correct Answer is C
Explanation
Choice A Reason: Homans' sign. This is an incorrect answer that refers to a different sign that is not related to pregnancy. Homans' sign is a sign of deep vein thrombosis (DVT) that occurs when there is pain or discomfort in the calf or popliteal region when the foot is dorsiflexed. Homans' sign can be elicited by passive or active movement of the foot, but it is not a reliable or specific indicator of DVT.
Choice B Reason: Chadwick's sign. This is an incorrect answer that refers to a different sign of pregnancy that affects the color of the cervix, not the texture. Chadwick's sign is a sign of pregnancy that refers to the bluish or purplish discoloration of the cervix, vagina, and vulva due to increased blood flow and congestion. Chadwick's sign can be observed by visual inspection of the cervix during the first prenatal visit, usually around 6 to 8 weeks of gestation.
Choice C Reason: Goodell's sign. This is because Goodell's sign is a sign of pregnancy that refers to the softening of the cervix due to increased vascularity and edema. Goodell's sign can be detected by digital examination of the cervix during the first prenatal visit, usually around 6 to 8 weeks of gestation.
Choice D Reason: McDonald's sign. This is an incorrect answer that refers to a different sign of pregnancy that involves the angle of the uterus, not the cervix. McDonald's sign is a sign of pregnancy that refers to the ease of flexing the body of the uterus against the cervix, which creates an angle of 90 degrees or less. McDonald's sign can be assessed by bimanual examination of the uterus during the first prenatal visit, usually around 7 to 8 weeks of gestation.
