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) Monitor uterine contractions is incorrect because this is not the most urgent intervention for a pregnant woman who has experienced a bleeding episode in late pregnancy. Uterine contractions can indicate labor or placental abruption, which are possible causes of bleeding in late pregnancy. However, they are not the only or the most reliable indicators of these conditions, as some women may have painless bleeding or contractions without bleeding. Moreover, monitoring uterine contractions does not address the immediate needs of the mother and the fetus, such as oxygenation, circulation, and perfusion. Therefore, this intervention should be done after assessing and stabilizing the vital signs and FHR.

Choice B) Assess fetal heart rate (FHR) and maternal vital signs is correct because this is the most important and essential intervention for a pregnant woman who has experienced a bleeding episode in late pregnancy. Bleeding in late pregnancy can be caused by various conditions, such as placenta previa, placental abruption, uterine rupture, or vasa previa, which can compromise the blood supply and oxygen delivery to the mother and the fetus. Assessing FHR and maternal vital signs can help to determine the severity and cause of the bleeding, as well as guide further

interventions such as fluid resuscitation, oxygen therapy, blood transfusion, or emergency delivery. The normal FHR range for a fetus is 110 to 160 beats per minute, and it may vary with fetal activity or maternal position. The normal maternal vital signs are: blood pressure 120/80 mm Hg or lower, heart rate 60 to 100 beats per minute, respiratory rate 12 to 20 breaths per minute, and temperature 36.5°C to 37.5°C (97.7°F to 99.5°F). Any deviation from these ranges may indicate hypoxia, hypovolemia, shock, infection, or distress. Therefore, this intervention should be done as soon as possible for women who have bleeding in late pregnancy.

Choice c) Perform a venipuncture for hemoglobin and hematocrit levels is incorrect because this is not a priority intervention for a pregnant woman who has experienced a bleeding episode in late pregnancy. Hemoglobin and hematocrit are blood tests that measure the amount of red blood cells and their percentage in the blood volume.

They can help to evaluate the extent of blood loss and the need for blood transfusion. However, they are not

immediate or accurate indicators of bleeding in late pregnancy, as they may take time to reflect the changes in blood volume or be affected by other factors such as hydration or hemodilution. Moreover, performing a venipuncture does not address the immediate needs of the mother and the fetus, such as oxygenation, circulation, and perfusion.

Therefore, this intervention should be done after assessing and stabilizing the vital signs and FHR.

Choice d) Place clean disposable pads to collect any drainage is incorrect because this is not a priority intervention for a pregnant woman who has experienced a bleeding episode in late pregnancy. Placing clean disposable pads can help to keep the perineal area clean and dry, as well as to estimate the amount and type of bleeding. However, it does not address the immediate needs of the mother and the fetus, such as oxygenation, circulation, and perfusion. Moreover, it does not provide any information about the cause or severity of the bleeding, as it may be affected by factors such as gravity or pooling. Therefore, this intervention should be done after assessing and stabilizing the vital signs and FHR.

Choice A: This is incorrect because weight less than the 10th percentile (SGA) means that the infant is smaller than expected for the gestational age, but not necessarily low birth weight. SGA infants may have intrauterine growth restriction due to maternal, placental, or fetal factors, but they may also be constitutionally small. SGA infants are at risk for hypoglycemia, hypothermia, polycythemia, and perinatal asphyxia.

Choice B: This is incorrect because weight greater than the 90th percentile means that the infant is larger than expected for the gestational age, but not necessarily high birth weight. Infants with weight greater than the 90th percentile are called large for gestational age (LGA) or macrosomic. LGA infants may have maternal diabetes, genetic factors, or post-term pregnancy as causes, but they may also be constitutionally large. LGA infants are at risk for birth trauma, shoulder dystocia, hypoglycemia, and respiratory distress.

Choice C: This is incorrect because weight between the 10th and 90th percentile means that the infant is appropriate for the gestational age (AGA), but not necessarily normal birth weight. AGA infants have a weight that matches their gestational age and are considered healthy and well-nourished. However, some AGA infants may have low or high birth weight depending on their gestational age at birth.

Choice D: This is the correct answer because low birth weight (LBW) is defined as a weight of 2500g or less at birth, regardless of the gestational age. LBW infants may be preterm (born before 37 weeks of gestation), term (born between 37 and 42 weeks of gestation), or post-term (born after 42 weeks of gestation). LBW infants are at risk for infection, bleeding, jaundice, and neurodevelopmental problems.
