A nurse reinforcing teaching about vitamin K with a client who is postpartum. Which of the following statements should the nurse include?

Choice A rationale :

Vitamin K decreases the newborn's risk of jaundice. Rationale: This statement is incorrect. Vitamin K plays no direct role in reducing the risk of jaundice in newborns. Jaundice is primarily caused by the accumulation of bilirubin in the blood, which is a different issue than hemorrhagic disorders.

Choice B rationale

Vitamin K decreases the newborn's risk of healthcare-associated infections. Rationale: This statement is incorrect. Vitamin K is not related to reducing the risk of healthcare-associated infections. Its main function is related to blood clotting and preventing hemorrhagic disorders.

Choice C rationale

Vitamin K decreases the newborn's risk of hemorrhagic disorders. Rationale: This statement is correct. Vitamin K is essential for the production of clotting factors in the blood, which helps prevent bleeding or hemorrhagic disorders in newborns. Newborns are born with low levels of vitamin K, so administering a vitamin K injection at birth is a common practice to prevent potential bleeding issues.

Choice D rationale

Vitamin K decreases the newborn's risk of complications from the Hepatitis B vaccine. Rationale: This statement is incorrect. Vitamin K is not directly related to reducing the risk of complications from the Hepatitis B vaccine. The vaccine is designed to protect against Hepatitis B infection, and vitamin K is not involved in its efficacy or safety.

Choice A rationale:

Choice A, fetal head compression, is not the correct answer in this case. Fetal head compression can cause early decelerations in the FHR, not variable decelerations. Early decelerations are often a result of the fetal head being compressed during contractions and are considered benign and expected during labor.

Choice B rationale:

The correct answer is choice B, which is umbilical cord compression. Variable decelerations of the fetal heart rate (FHR) can occur during labor due to various rationales, and umbilical cord compression is one of the common causes. When the umbilical cord gets compressed, it can briefly reduce or restrict the blood flow and oxygen supply to the fetus, leading to temporary decelerations in the FHR.

Choice C rationale:

Choice C, maternal fever, is also not the correct answer for variable decelerations in FHR. Maternal fever can be a sign of infection, and it may lead to other fetal heart rate abnormalities, such as tachycardia (an increased heart rate), but it is not specifically associated with variable decelerations.

Choice D rationale:

Choice D, polyhydramnios, is not the cause of variable decelerations in this scenario. Polyhydramnios refers to an excessive accumulation of amniotic fluid around the fetus. While it can have implications for pregnancy, it is not directly linked to variable decelerations of the FHR.
