To protect newborns from infection while in the nursery, the nurse plans to:

Check the client's fundus. Lochia rubra is the normal vaginal bleeding and discharge that occurs after childbirth. It consists of blood, mucus, and tissue from the placenta and the uterus lining. It is usually bright red and may have some clots, but these clots should not be big or difficult to pass. If the client has a large amount of lochia rubra with several clots, it may indicate that the uterus is not contracting well and needs to be massaged to expel any retained tissue or blood. Checking the client's fundus is the first action the nurse should take to assess the uterine tone and location.

Choice A is incorrect because requesting the provider perform a vaginal examination is not the first action the nurse should take. A vaginal examination may be necessary if the fundal massage does not reduce the bleeding or if there is a suspicion of lacerations or hematoma, but it is not a priority intervention.

Choice C is incorrect because measuring the client's vital signs is not the first action the nurse should take. Vital signs can help monitor the client's hemodynamic status and identify signs of shock, such as tachycardia, hypotension, and pallor, but they are not as important as checking the fundus in this situation.

Choice D is incorrect because feeling for a full bladder is not the first action the nurse should take. A full bladder can displace the uterus and interfere with its contraction, leading to increased bleeding. However, it is not as likely as uterine atony to cause a large amount of lochia rubra with several clots.

Sternal or chest retractions. This is because sternal or chest retractions are a sign of respiratory distress in newborns, which means they are having difficulty breathing. Chest retractions occur when the baby's chest pulls in with each breath, indicating that they are using extra muscles to breathe. This can be caused by various conditions that affect the lungs, such as respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), meconium aspiration syndrome (MAS), pneumonia, or congenital heart defects.

Choice A is not correct because mucus draining from the nose is not a symptom of respiratory distress in newborns. It is normal for newborns to have some mucus in their nose and mouth after birth, which can be cleared by suctioning or wiping.

Mucus drainage does not interfere with breathing unless it is excessive or thick.

Choice B is not correct because cyanosis of the hands and feet is not a symptom of respiratory distress in newborns. It is normal for newborns to have bluish discoloration of their hands and feet, called acrocyanosis, for the first few days after birth. This is due to immature circulation and does not indicate a lack of oxygen. Cyanosis of the central parts of the body, such as the face, lips, and tongue, is more concerning and should be reported.

Choice C is not correct because irregular heart rate is not a symptom of respiratory distress in newborns. It is normal for newborns to have some variations in their heart rate, especially during sleep cycles. The normal heart rate range for newborns is 100 to 160 beats per minute. A heart rate that is too fast (tachycardia) or too slow (bradycardia) may indicate a problem with the heart or other organs³.
