A nurse in a provider's office is caring for a client who is at 34 weeks of gestation and at risk for placental abruption. The nurse should recognize that which of the following is the most common risk factor for abruption?

Choice A rationale
This is incorrect because a client who has missed a period and reports vaginal spotting is not the most urgent case. This could indicate a possible pregnancy or a menstrual irregularity, but it is not a life-threatening condition. The nurse should see this client after assessing the other clients.

Choice B rationale
This is correct because a client who is at 28 weeks of gestation and reports painless vaginal bleeding is the most urgent case. This could indicate a placenta previa, which is a condition where the placenta covers the cervical opening and can cause severe hemorrhage and fetal distress. The nurse should see this client immediately and prepare for an emergency cesarean section.

Choice C rationale
This is incorrect because a client who is at 38 weeks of gestation and reports a cough and fever is not the most urgent case. This could indicate a respiratory infection, which can affect the maternal and fetal well-being, but it is not a life-threatening condition. The nurse should see this client after assessing the other clients and administer antibiotics and antipyretics as prescribed.

Choice D rationale
This is incorrect because a client who is at 14 weeks of gestation and reports nausea and vomiting is not the most urgent case. This could indicate a normal pregnancy symptom or a hyperemesis gravidarum, which is a condition where the nausea and vomiting are severe and persistent. The nurse should see this client after assessing the other clients and provide hydration and antiemetics as prescribed.

Choice A rationale
This is correct because the newborn might be actively shedding the virus if the mother has rubella at the time of delivery. Rubella is a highly contagious viral infection that can be transmitted through respiratory droplets or contact with body fluids. The newborn should be placed in isolation to prevent the spread of the infection to other susceptible individuals, such as pregnant women or immunocompromised persons.

Choice B rationale
This is incorrect because the child might develop encephalitis, a complication of rubella, is not an appropriate response by the nurse. Encephalitis is a rare but serious condition that involves inflammation of the brain. It can occur as a complication of rubella, but it is more common in adults than in children. The nurse should not scare the mother with this possibility, but rather focus on the prevention of transmission.

Choice C rationale
This is incorrect because the newborn is at risk for developing a TORCH infection is not an appropriate response by the nurse. TORCH is an acronym for a group of infections that can cause congenital anomalies in the fetus or newborn. It stands for toxoplasmosis, other infections (such as syphilis, varicella, or parvovirus), rubella, cytomegalovirus, and herpes simplex virus. The nurse should not use this term, as it is vague and confusing for the mother. The nurse should specify the type of infection and the potential consequences for the newborn.

Choice D rationale
This is incorrect because exposure to rubella will suppress the newborn's immune response is not an appropriate response by the nurse. Exposure to rubella will not suppress the newborn's immune response, but rather stimulate it to produce antibodies against the virus. However, these antibodies may not be sufficient to protect the newborn from the infection, and they may interfere with the effectiveness of the rubella vaccine later in life. The nurse should explain the importance of immunization for the newborn and the mother.
