What is low birth weight classified as?
Weight is less than the 10th percentile (SGA)
Weight is greater than 90th percentile
Weight is between 10th and 90th percentile
Weight of 2500g or less at birth
The Correct Answer is D
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.

Correct Answer is C
Explanation
Choice a) Have the parent fold the infant's arms across the chest is incorrect because this is not a helpful way to calm a preterm infant. Folding the arms across the chest can restrict the infant's breathing and movement, and may increase their stress and discomfort. Preterm infants need gentle and supportive touch, not restraint or pressure.
Choice b) Encourage the parent to place the infant back in the warmer is incorrect because this is not a necessary or beneficial action for a preterm infant who is showing signs of overstimulation. Placing the infant back in the warmer can interrupt the bonding and attachment process between the parent and the infant, and may make the infant feel more isolated and insecure. Preterm infants need close and frequent contact with their parents, not separation or detachment.
Choice c) Encourage the parent to do kangaroo care is correct because this is an effective and evidence-based method of soothing and stabilizing a preterm infant who is experiencing overstimulation. Kangaroo care is a technique where the parent holds the infant skin-to-skin on their chest, providing warmth, comfort, and security. Kangaroo care can reduce the infant's stress hormones, lower their heart rate and blood pressure, improve their oxygenation and breathing, enhance their growth and development, and strengthen their bond with their parent.
Choice d) Cover the infant with a warm bed blanket is incorrect because this is not a sufficient or optimal way to comfort a preterm infant who is displaying signs of overstimulation. Covering the infant with a warm bed blanket can provide some warmth and protection, but it does not offer the same benefits as kangaroo care. A warm bed blanket cannot mimic the parent's heartbeat, voice, smell, and movement, which are essential for the infant's emotional and physiological well-being. Preterm infants need human touch and interaction, not just physical warmth.
Correct Answer is C
Explanation
Choice A) Missed abortion: This is not the correct obstetric complication for methotrexate treatment. A missed abortion is a type of miscarriage in which the fetus has died but the products of conception are still retained in the uterus. Methotrexate is not used for this condition, as it can cause toxicity and bleeding. The usual treatment options for a missed abortion are expectant management, medical induction, or surgical evacuation.
Choice B) Abruptio placentae: This is not the correct obstetric complication for methotrexate treatment. Abruptio placentae is a condition in which the placenta separates from the uterine wall before delivery, causing bleeding and fetal distress. Methotrexate is not used for this condition, as it can worsen the bleeding and harm the fetus. The usual treatment options for abruptio placentae depend on the severity of the condition and the gestational age, but they may include fluid resuscitation, blood transfusion, tocolysis, or emergency delivery.
Choice C) Unruptured ectopic pregnancy: This is the correct obstetric complication for methotrexate treatment. An ectopic pregnancy is a pregnancy that implants outside of the uterine cavity, usually in the fallopian tube. An unruptured ectopic pregnancy is one that has not caused any bleeding or rupture of the tube. Methotrexate is used for this condition, as it can dissolve the pregnancy tissue and prevent further growth and complications.
Methotrexate is given as an injection and works by inhibiting folic acid metabolism, which is essential for cell division.
Methotrexate is only suitable for patients who have stable vital signs, low levels of human chorionic gonadotropin (hCG), and no fetal heartbeat or cardiac activity detected by ultrasound.
Choice D) Complete hydatidiform mole: This is not the correct obstetric complication for methotrexate treatment. A complete hydatidiform mole is a type of gestational trophoblastic disease in which there is an abnormal proliferation of placental tissue without any fetal development. Methotrexate is not used for this condition, as it can cause resistance and recurrence. The usual treatment option for a complete hydatidiform mole is suction curettage, which removes the molar tissue from the uterus.
