A nurse is assisting with the care of a client who is in labour and has an external electronic fetal monitor. The nurse observes that the fetal heart rate begins to decelerate after the contraction has started, with the lowest point of the deceleration occurring after the peak of the contraction. Which of the following actions should the nurse take first?
Increase the rate of the maintenance IV infusion.
Administer oxygen using a nonrebreather mask.
Elevate the client's legs.
Place the client in the lateral position.
The Correct Answer is D
Choice A rationale:
Increasing the rate of the maintenance IV infusion may be a rational action in some situations, but it is not the first priority when dealing with a fetal heart rate deceleration. The priority is to address the deceleration and potential fetal distress promptly.
Choice B rationale:
Administering oxygen using a nonrebreather mask might be beneficial for the client, but it is not the primary action to take when dealing with fetal heart rate deceleration. The priority is to address the deceleration and ensure fetal well-being.
Choice C rationale:
Elevating the client's legs is unlikely to have a significant impact on fetal heart rate deceleration. This action is more relevant in cases of maternal hypotension or when trying to improve venous return to the heart. It is not the first-line intervention for fetal heart rate decelerations.
Choice D rationale:
Placing the client in the lateral (side-lying) position is the correct action to take first. This position can help relieve pressure on the vena cava, improve blood flow, and increase oxygen supply to the fetus. By changing the client's position, the nurse can potentially resolve the fetal heart rate deceleration and improve fetal well-being.

Correct Answer is B
Explanation
Choice A reason:
Initiating epidural anesthesia too soon may delay rupture of fetal membranes. This statement is not accurate. Epidural anesthesia itself does not have a direct impact on the rupture of fetal membranes. The timing of rupturing membranes is determined based on the progress of labor and other clinical indications. There is no causal relationship between epidural anesthesia and the timing of membrane rupture.
Choice B reason:
Initiating epidural anesthesia too soon can prolong labor. This statement is correct. Epidural anesthesia, while providing pain relief during labor, can also cause some degree of motor blockage and decrease the woman's ability to push effectively. This can potentially lead to a lengthening of the labor process. It is generally recommended to wait until a good labor pattern has been established to avoid unnecessary prolongation of labor.
Choice C reason:
Initiating epidural anesthesia too soon can cause fetal depression. This statement is not entirely accurate. Epidural anesthesia can cross the placenta and reach the fetus, but the effect on the baby is usually minimal. However, fetal monitoring is essential during labor to ensure the baby's well-being, regardless of whether epidural anesthesia is used or not.
Choice D reason:
Initiating epidural anesthesia too soon can cause maternal hypertension. This statement is not supported by evidence. Epidural anesthesia does not typically cause maternal hypertension. It can, however, lead to a decrease in blood pressure in some cases, which is why careful monitoring of maternal blood pressure is necessary during and after the administration of epidural anesthesia.
Correct Answer is A
Explanation
Choice A: The correct answer is (a) Bleeding. The purpose of administering vitamin K to a newborn following delivery is to prevent bleeding complications. Vitamin K plays a crucial role in the synthesis of blood clotting factors, specifically factors II, VII, IX, and X. Newborns have low levels of vitamin K at birth, and it takes a few days for their bodies to start producing it. This places them at risk of developing vitamin K deficiency bleeding (VKDB), which can lead to serious bleeding problems, including bleeding into the brain (intracranial haemorrhage). By giving the newborn a vitamin K injection, this deficiency is corrected, reducing the risk of bleeding complications.
Choice B rationale
(b) Infection. Administering vitamin K to a newborn is not intended to prevent infections. Vitamin K is essential for blood clotting and does not have a direct role in preventing or treating infections. Infection prevention measures involve proper hygiene practices and vaccination, but vitamin K is unrelated to this aspect of care.
Choice C rationale
(c) Potassium deficiency. Administering vitamin K to a newborn has no impact on potassium levels. Potassium is a different essential nutrient that plays a vital role in various physiological processes, but it is not related to blood clotting. The administration of vitamin K is specific to preventing bleeding complications, not addressing potassium deficiency.
Choice D rationale
(d) Hyperbilirubinemia. The correct answer is not (d) Hyperbilirubinemia. Vitamin K administration is not aimed at preventing or treating hyperbilirubinemia, a condition characterized by elevated levels of bilirubin in the blood. Hyperbilirubinemia is related to the breakdown of red blood cells and the liver'sability to process bilirubin, whereas vitamin K's primary role is in the clotting cascade.
