A nurse in calculating the estimated date of birth using Nägele's rule for a client who is pregnant and whose last menstrual cycle started june 21. Which of the following is the estimated date of delivery in the next year?

A. Give oxytocin 20 units IV bolus: Oxytocin is a medication used to induce or augment labor, and it is not the appropriate intervention for a client with placenta previa and significant vaginal bleeding. The priority in this situation is to assess and manage the bleeding.

B. Obtain serial hemoglobin and hematocrit: This is the correct action. Placenta previa can lead to significant bleeding, and obtaining serial hemoglobin and hematocrit levels will help monitor the extent of blood loss and guide decisions regarding transfusions or other interventions.

C. Perform a fundal massage: Fundal massage is not the appropriate intervention for placenta previa. In cases of placenta previa, the placenta is covering or near the cervical os, and vigorous fundal massage can worsen bleeding.

D. Assess for abdominal tenderness: While assessing for abdominal tenderness is important in the overall assessment of a pregnant client, in the context of active bleeding with placenta previa, the immediate focus should be on assessing the extent of bleeding and the client's hemodynamic status.

A. Erythema toxicum: Erythema toxicum is a common and benign rash that appears in the first few days of life. It is characterized by pink or red blotches with a small, pimple-like elevation in the center. It is unrelated to a nuchal cord.

B. Periauricular papillomas: Periauricular papillomas are small skin tags or growths around the external ear. They are not typically associated with a nuchal cord and are unrelated to the newborn's delivery.

C. Facial petechiae: A nuchal cord occurs when the umbilical cord is wrapped around the baby's neck. During delivery, this can lead to pressure on the baby's head and face, resulting in small, pinpoint red or purple spots known as petechiae. These are often seen on the face and neck and are considered a transient and benign finding.

D. Telangiectatic nevi: Telangiectatic nevi, also known as "stork bites" or "angel kisses," are common vascular birthmarks. They are not specifically associated with a nuchal cord but rather represent dilated blood vessels near the surface of the skin.
