An adolescent patient at 20 weeks gestation states that it is important not to have a baby that weighs too much. She states this has been her rationale for limiting calories. Her weight has decreased from 110 pounds to 106 pounds.
What would be the best nursing response? Select one:

Choice A Reason: Maintain the client on strict bedrest. This is an inappropriate action that may worsen the client's condition and increase her isolation and depression. Postpartum psychosis requires prompt psychiatric treatment with medication and psychotherapy, not bedrest.

Choice B Reason: Carefully monitor intake and output. This is an irrelevant action that has no direct relation to postpartum psychosis or its management. Monitoring intake and output may be indicated for other postpartum complications such as hemorrhage, infection, or preeclampsia.

Choice C Reason: Restrict visitation of the client's partner. This is an unnecessary action that may deprive the client of social support and emotional comfort. The partner may be an important source of help and information for the client and the health care team. The partner should be involved in the client's care and education, unless there are signs of abuse or violence.

Choice D Reason: Closely supervise all infant care and interaction. This is because postpartum psychosis is a severe mental disorder that occurs in some women after childbirth, which can cause delusions, hallucinations, paranoia, mood swings, confusion, and suicidal or homicidal thoughts. Postpartum psychosis can pose a danger to both the mother and the infant, as the mother may harm herself or the infant due to distorted perceptions or impulses. The nurse should closely supervise all infant care and interaction to ensure safety and prevent injury.

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.
