A nurse is reinforcing teaching with a new mother about the purpose of administering vitamin K to her newborn following delivery. The nurse should explain that the purpose of administering vitamin K is to prevent which of the following complications?
Bleeding.
Infection.
Potassium deficiency.
Hyperbilirubinemia.
The Correct Answer is A
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's ability to process bilirubin, whereas vitamin K's primary role is in the clotting cascade.

Correct Answer is D
Explanation
The correct answer is D. Cover the client with warm blankets.
Choice A rationale:
Shaking chills are not always associated with fever, especially during the immediate postpartum period. While determining the client's temperature can rule out infection, this action does not provide immediate relief or comfort. The chills are often physiological due to hormonal and vascular changes.
Choice B rationale:
Seizure precautions are unnecessary unless additional symptoms, such as loss of consciousness or convulsions, are observed. Shaking chills are typically not indicative of a neurological event but rather a normal postpartum response.
Choice C rationale:
Notifying the charge nurse is unnecessary unless the shaking is accompanied by other abnormal findings, such as fever or prolonged chills. The immediate priority is to ensure client comfort.
Choice D rationale:
Providing warm blankets addresses the primary issue of discomfort caused by postpartum chills. This is a standard intervention to stabilize the client's body temperature and promote comfort. The action is immediate, non-invasive, and effective.
Correct Answer is D
Explanation
Choice A rationale:
Helping the client to the bathroom to empty her bladder is not the appropriate response in this situation. The client's sudden urge to push indicates that she is in the second stage of labor, which is the pushing phase. The cervix is already dilated at 7 cm, and the fetus is at 1+ station, indicating that delivery is imminent. Emptying the bladder at this point is not a priority and may delay necessary actions.
Choice B rationale:
Assisting the client into a comfortable position is also not the appropriate response. The client's urge to push suggests that she is in the active stage of labor, and her cervix is already 7 cm dilated. Encouraging a comfortable position might not be suitable since the focus should be on monitoring the progress of labor and preparing for delivery.
Choice C rationale:
Having the client pant during the next few contractions is not the correct response either. Panting is typically recommended during the transition phase of labor to prevent rapid pushing and potential damage to the perineum. However, in this scenario, the client is already fully dilated, and the fetus is at 1+ station, indicating that the second stage of labor has commenced. Panting is not necessary at this point.
Choice D rationale:
The appropriate nursing response is to assess the perineum for signs of crowning. The sudden urge to push indicates that the baby is descending through the birth canal and may be close to crowning, which is when the baby's head becomes visible at the vaginal opening. By assessing for crowning, the nurse can determine if delivery is imminent and notify the healthcare provider for further actions and preparation for the baby's birth.
