A first-time father is changing the diaper of his 1-day-old daughter. He asks the nurse, "What is this black, sticky stuff in her diaper?" The nurse's best response is:

Choice a) Check the baby's diaper is incorrect because this is not a priority action for a baby who is grunting in the neonatal nursery. Grunting is a sign of respiratory distress, which means that the baby is having difficulty breathing and is trying to keep air in the lungs by making a low-pitched sound with each expiration. Checking the baby's diaper may be part of routine care, but it does not address the underlying cause of the grunting or improve the baby's oxygenation. Therefore, this action should be done after assessing and treating the baby's respiratory status.

Choice b) Place a pacifier in the baby's mouth is incorrect because this is not an appropriate action for a baby who is grunting in the neonatal nursery. Grunting is a sign of respiratory distress, which means that the baby is having difficulty breathing and is trying to keep air in the lungs by making a low-pitched sound with each expiration. Placing a pacifier in the baby's mouth may interfere with the baby's breathing and worsen the grunting, as it can obstruct the airway, increase the work of breathing, or cause aspiration. Therefore, this action should be avoided or used with caution for babies who are grunting.

Choice c) Have the mother feed the baby is incorrect because this is not a safe action for a baby who is grunting in the neonatal nursery. Grunting is a sign of respiratory distress, which means that the baby is having difficulty breathing and is trying to keep air in the lungs by making a low-pitched sound with each expiration. Having the mother feed the baby may increase the risk of choking or aspiration, as the baby may not be able to coordinate sucking, swallowing, and breathing. Therefore, this action should be delayed or modified until the baby's respiratory status improves.

Choice d) Assess the respiratory rate is correct because this is the most important action for a baby who is grunting in the neonatal nursery. Grunting is a sign of respiratory distress, which means that the baby is having difficulty breathing and is trying to keep air in the lungs by making a low-pitched sound with each expiration. Assessing the respiratory rate can help to determine the severity and cause of the respiratory distress, as well as guide further interventions such as oxygen therapy, suctioning, or medication. The normal respiratory rate for a newborn ranges from 30 to 60 breaths per minute, and it may vary with sleep or activity. A respiratory rate above 60 breaths per minute or below 30 breaths per minute indicates abnormality and requires immediate attention. Therefore, this action should be done as soon as possible for babies who are grunting.

Choice a) Placenta previa is incorrect because this is a condition where the placenta partially or completely covers the cervix, which can cause painless vaginal bleeding in the third trimester. It is not related to trauma and does not require hospitalization unless bleeding occurs.

Choice b) Dehydration is incorrect because this is a condition where the body loses more fluid than it takes in, which can cause symptoms such as thirst, dry mouth, headache, fatigue, and dizziness. It is not a complication of pregnancy and can be prevented by drinking enough water and avoiding caffeine and alcohol.

Choice c) Gestational hypertension is incorrect because this is a condition where the blood pressure rises above 140/90 mmHg after 20 weeks of pregnancy, which can cause complications such as preeclampsia, eclampsia, and fetal growth restriction. It is not caused by trauma and can be managed by regular antenatal care and medication if needed.

Choice d) Abruptio placentae is correct because this is a condition where the placenta separates from the uterine wall before delivery, which can cause severe vaginal bleeding, abdominal pain, uterine contractions, and fetal distress. It is a life-threatening emergency that can be triggered by trauma and requires immediate delivery of the baby and treatment of shock and blood loss. Therefore, a woman who is 8 months pregnant and involved in a serious motor vehicle crash should be admitted to the hospital for observation for this complication.
