The nurse administers vitamin K intramuscularly as prophylaxis to the newborn based on which of the following rationales?
Select one:
Vitamin K will increase erythropoiesis.
Vitamin K will enhance bilirubin breakdown.
Vitamin K will stop Rh sensitization.
Vitamin K will promote blood clotting ability. Vitamin K will promote blood clotting ability.
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A Reason: "Your body is responding to the events of labor, just like after a tough workout." This is an inaccurate statement that does not explain the cause of the contractions or reassure the client.
Choice B Reason: "This could be a sign that your body is trying to get rid of retained placental fragments." This is an alarming statement that may scare the client and imply that something is wrong. Retained placental fragments are rare and usually cause heavy bleeding, fever, and infection.
Choice C Reason: "Let me check your vaginal discharge just to make sure everything is fine." This is an unnecessary statement that does not answer the client's question or provide any information.
Choice D Reason:"The baby's sucking releases oxytocin which causes your uterus to contract." This is a correct statement that explains the physiological mechanism of the contractions and reassures the client that they are normal and beneficial.
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.
