The nurse is about to administer phytonadione to a newborn.
Which statement by the parents shows they understand why this medication is being given?
It stimulates the immune system.
It aids an immature liver.
It prevents hemorrhagic disorders.
It compensates for insufficient dietary intake.
The Correct Answer is C
Choice A rationale
While it’s true that phytonadione, also known as vitamin K, plays a role in the immune system, this is not the primary reason it is given to newborns. Therefore, this statement does not show an understanding of why the medication is being given.
Choice B rationale
Phytonadione does not aid an immature liver. It is necessary for the synthesis of certain proteins required for blood clotting. However, it does not directly aid the liver’s function.
Choice C rationale
This is the correct statement. Phytonadione is given to newborns to prevent hemorrhagic disorders, specifically vitamin K deficiency bleeding (VKDB). Newborns are at risk for VKDB because their gut does not yet have the bacteria necessary to produce vitamin K5.
Choice D rationale
While it’s true that vitamin K is obtained from dietary intake, newborns do not receive phytonadione to compensate for insufficient dietary intake. They receive it to prevent VKDB, a bleeding disorder caused by vitamin K deficiency.

Correct Answer is B
Explanation
Choice A rationale
While hard, painful uterine afterpains can be uncomfortable for the patient, they are a normal part of the postpartum period and are not typically a priority complication following a severe postpartum hemorrhage16.
Choice B rationale
Disseminated intravascular coagulation (DIC) is a serious condition that can occur as a complication of severe postpartum hemorrhage. It involves an overactive clotting process leading to the formation of small blood clots that can block blood vessels and cause significant organ damage16.
Choice C rationale
Postpartum psychosis is a serious mental health disorder that can occur after childbirth. However, it is not directly related to postpartum hemorrhage and would not typically be the priority complication in this scenario16.
Choice D rationale
Placenta accreta is a condition where the placenta grows too deeply into the uterine wall. While it can cause severe bleeding after delivery, it would not typically be a priority complication to assess for following a severe postpartum hemorrhage16.
Correct Answer is C
Explanation
Choice A rationale
While shallow and irregular respirations can be a sign of respiratory distress in newborns, it is not the most indicative symptom. Newborns naturally have irregular breathing patterns, which can include periods of rapid breathing followed by periods of no breathing for up to 10 seconds.
Choice B rationale
A respiratory rate of 50 breaths per minute is within the normal range for a newborn. Newborns typically breathe at a rate of 40 to 60 breaths per minute.
Choice C rationale
Flaring of the nares, or nostrils, is a common sign of respiratory distress in newborns. It indicates that the baby is working hard to breathe.
Choice D rationale
Abdominal breathing with synchronous chest movement is normal in newborns. It is not a sign of respiratory distress.
