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 B
Explanation
Choice A Reason: Prepare for IV dextrose administration. This is an incorrect answer that indicates an unnecessary and invasive intervention for an IDM with normal blood glucose. IV dextrose administration is indicated for an IDM with severe or persistent hypoglycemia, which is defined as a blood glucose below 40 mg/dL or below 60 mg/dL after two feedings.
Choice B Reason: Provide routine care, per hospital IDM protocol. This is because a blood glucose of 60 is within the normal range for an IDM, which is 40 to 80 mg/dL. An IDM is a newborn whose mother has pre-existing or gestational diabetes, which can affect the fetal and neonatal glucose metabolism and regulation. An IDM may have hypoglycemia (low blood glucose), hyperglycemia (high blood glucose), or other complications such as macrosomia, polycythemia, or congenital anomalies. An IDM requires routine care and monitoring according to the hospital IDM protocol, which may include blood glucose testing, feeding, temperature regulation, and observation for signs of distress.
Choice C Reason: Place the infant in a warmed incubator. This is an incorrect answer that suggests an irrelevant and potentially harmful action for an IDM with normal blood glucose. Placing the infant in a warmed incubator is indicated for an IDM with hypothermia, which is a low body temperature that can impair glucose utilization and increase oxygen consumption. However, placing the infant in a warmed incubator without proper indication can cause hyperthermia, which is a high body temperature that can lead to dehydration, electrolyte imbalance, or brain damage.
Choice D Reason: Alert the clinician immediately for orders. This is an incorrect answer that implies an urgent and unwarranted situation for an IDM with normal blood glucose. Alerting the clinician immediately for orders is indicated for an IDM with signs of distress or complications, such as apnea, cyanosis, seizures, or jaundice.
Correct Answer is A
Explanation
Choice A Reason: Latent phase of the first stage of labor. This is because this phase is characterized by mild and irregular contractions, slow cervical dilation (up to 4 cm), minimal cervical effacement (up to 40%), and minimal discomfort or pain. The latent phase is also known as the early phase or preparatory phase of labor.
Choice B Reason: Transition phase of the first stage of labor. This is an incorrect answer that describes a different phase with different characteristics. The transition phase is marked by strong and frequent contractions, rapid cervical dilation (from 8 to 10 cm), complete cervical effacement (100%), and intense discomfort or pain. The transition phase is also known as the terminal phase or acceleration phase of labor.
Choice C Reason: Perineal phase of the second stage of labor. This is an incorrect answer that refers to another stage and phase with different features. The second stage of labor begins with complete cervical dilation (10 cm) and ends with delivery of the baby. The perineal phase is the last part of the second stage, where the baby's head crowns and emerges through the vaginal opening.
Choice D Reason: Active phase of the first stage of labor. This is an incorrect answer that indicates another phase with different atributes. The active phase is characterized by moderate and regular contractions, progressive cervical dilation (from 4 to 8 cm), increased cervical effacement (from 40% to 80%), and increased discomfort or pain. The active phase is also known as the middle phase or dilatation phase of labor.
