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.

Answer and Explanation

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 D

Explanation

Choice A Reason: Vitamin K will increase erythropoiesis. This is an incorrect statement that confuses vitamin K with erythropoietin. Erythropoietin is a hormone that stimulates red blood cell production in the bone marrow. Vitamin K does not aﬀect erythropoiesis.

Choice B Reason: Vitamin K will enhance bilirubin breakdown. This is an incorrect statement that confuses vitamin K with phototherapy. Phototherapy is a treatment that exposes the newborn's skin to light, which converts bilirubin into water-soluble forms that can be excreted by the liver and kidneys. Bilirubin is a yellow pigment that results from the breakdown of red blood cells. High levels of bilirubin can cause jaundice and brain damage in newborns. Vitamin K does not aﬀect bilirubin metabolism.

Choice C Reason: Vitamin K will stop Rh sensitization. This is an incorrect statement that confuses vitamin K with Rh immune globulin. Rh immune globulin is an injection given to Rh-negative mothers who deliver Rh-positive babies, to prevent them from developing antibodies against Rh-positive blood cells in future pregnancies. Rh sensitization is a condition where the mother's immune system atacks the baby's blood cells, causing hemolytic disease of the newborn. Vitamin K does not aﬀect Rh sensitization.

Choice D Reason: Vitamin K will promote blood clotting ability. This is a correct statement that explains the rationale for administering vitamin K as prophylaxis to newborns. Vitamin K is essential for the synthesis of clotting factors in the liver. Newborns have low levels of vitamin K at birth due to poor placental transfer and lack of intestinal bacteria that produce vitamin K. Therefore, they are at risk of bleeding disorders such as hemorrhagic disease of the newborn.

A. Frequent voiding encourages sphincter control. B. A full bladder impedes oxygen ﬂow to the fetus. C. Frequent voiding prevents bruising of the bladder. D. A full bladder can impede fetal descent.

Correct Answer is D

Explanation

Choice A Reason: Frequent voiding encourages sphincter control. This is an incorrect statement that has no relevance to labor and delivery. Sphincter control refers to the ability to contract and relax the muscles that control urination and defecation. It is not aﬀected by frequent voiding.

Choice B Reason: A full bladder impedes oxygen ﬂow to the fetus. This is an incorrect statement that confuses a full bladder with a prolapsed cord. A prolapsed cord is a condition where the umbilical cord slips through the cervix before the baby and becomes compressed by the fetal head, which can reduce oxygen ﬂow to the fetus. A full bladder does not aﬀect oxygen ﬂow to the fetus.

Choice C Reason: Frequent voiding prevents bruising of the bladder. This is an incorrect statement that exaggerates the eﬀect of a full bladder on the bladder wall. A full bladder may cause some pressure or discomfort on the bladder, but it does not cause bruising or damage.

Choice D Reason: A full bladder can impede fetal descent. This is a correct statement that explains why it is important for the nurse to assess the bladder regularly and encourage the laboring client to void every 2 hours.
