The nurse assesses a newborn at 36 weeks' gestation, and the following behaviors are noted: nasal flaring, labored breathing, and excessive mucus. The nurse is most concerned about:
Select one:

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.

Choice A Reason: Obtain a bilirubin level. This is an incorrect answer that indicates an irrelevant and unnecessary nursing action for a newborn with tremors or jiteriness. Obtaining a bilirubin level is a nursing action that is indicated for a newborn with jaundice (yellowish discoloration of the skin and mucous membranes), which can occur due to increased bilirubin production or decreased bilirubin excretion. Jaundice does not cause tremors or jiteriness in newborns.

Choice B Reason: Place a pulse oximeter on the newborn. This is an incorrect answer that suggests an inappropriate and insufficient nursing action for a newborn with tremors or jiteriness. Placing a pulse oximeter on the newborn is a nursing action that measures oxygen saturation and heart rate, which can indicate hypoxia (low oxygen level) or distress in newborns. Hypoxia can cause tremors or jiteriness in newborns, but it is not the only or most likely cause. Placing a pulse oximeter on the newborn does not provide enough information to diagnose or treat hypoglycemia.

Choice C Reason: Obtain a blood glucose level. This is because tremors or jiteriness are common signs of hypoglycemia (low blood glucose) in newborns, which can occur due to various factors such as prematurity, maternal diabetes, infection, or cold stress. Hypoglycemia can cause neurological damage or death if not treated promptly and effectively. Obtaining a blood glucose level is a nursing action that has the highest priority for a newborn with tremors or jiteriness, as it can confirm the diagnosis and guide the treatment.

Choice D Reason: Take the newborn's vital signs. This is an incorrect answer that implies an inadequate and delayed nursing action for a newborn with tremors or jiteriness. Taking the newborn's vital signs is a nursing action that monitors temperature, pulse, respiration, and blood pressure, which can indicate general health status and stability in newborns. Taking the newborn's vital signs may reveal signs of hypoglycemia, such as hypothermia, tachycardia, tachypnea, or hypotension, but it is not a specific or definitive test for hypoglycemia. Taking the newborn's vital signs may also waste valuable time that could be used to obtain a blood glucose level and initiate treatment.
