Which is true about newborns classified as small for gestational age (SGA)?
They are born before 38 weeks of gestation.
Placental malfunction is the only recognized cause of this condition.
They weigh less than 2500 g.
They are below the 10th percentile on gestational growth charts.
The Correct Answer is D
Choice a) They are born before 38 weeks of gestation is incorrect because this is not the definition of SGA. SGA refers to newborns who have a birth weight or length that is significantly lower than expected for their gestational age, regardless of when they are born. Therefore, a newborn can be SGA even if they are born at term or post-term.
Choice b) Placental malfunction is the only recognized cause of this condition is incorrect because this is not the only factor that can contribute to SGA. Placental malfunction can cause fetal growth restriction due to insufficient blood supply and nutrients to the fetus, but there are other possible causes such as maternal factors (e.g.,
hypertension, diabetes, smoking, malnutrition), fetal factors (e.g., chromosomal abnormalities, infections, congenital anomalies), and environmental factors (e.g., altitude, pollution, stress).
Choice c) They weigh less than 2500 g is incorrect because this is not the criterion for SGA. SGA is based on the comparison of the newborn's weight or length with the expected values for their gestational age, not on an absolute cutoff. Therefore, a newborn can be SGA even if they weigh more than 2500 g, as long as they are below the 10th percentile for their gestational age.
Choice d) They are below the 10th percentile on gestational growth charts is correct because this is the most commonly used definition of SGA. Gestational growth charts are tools that plot the expected weight or length of a fetus or newborn according to their gestational age and sex. They are based on population data and can vary
depending on the ethnicity and region of origin of the mother and the baby. A newborn who falls below the 10th percentile on these charts is considered SGA, meaning that they have grown less than 90% of their peers .

Correct Answer is D
Explanation
Choice a) Urine output of 200 mL for the past 8 hours is incorrect because this is a normal finding for a postpartum woman. The average urine output for a healthy adult is about 800 to 2000 mL per day, which means about 100 to 250 mL per hour. Therefore, a urine output of 200 mL for the past 8 hours is within the normal range and does not indicate any complications.
Choice b) Weight decrease of 2 pounds since delivery is incorrect because this is also a normal finding for a postpartum woman. The weight loss is due to the expulsion of the placenta, amniotic fluid, and blood during delivery. A postpartum woman can expect to lose about 10 to 12 pounds immediately after giving birth, and another 5 pounds in the following weeks due to fluid loss. Therefore, a weight decrease of 2 pounds since delivery is not a cause for concern and does not need to be reported to the obstetrician.
Choice c) Pulse rate of 65 beats per minute is incorrect because this is also a normal finding for a postpartum woman. The normal resting pulse rate for an adult ranges from 60 to 100 beats per minute, and it may decrease slightly after delivery due to blood loss and reduced cardiac output. Therefore, a pulse rate of 65 beats per minute is not indicative of any problems and does not require any intervention.
Choice d) Drop in hematocrit of 6% since admission is correct because this is an abnormal finding for a postpartum woman and suggests that she has developed anemia due to excessive blood loss. Hematocrit is the percentage of red blood cells in the blood, and it reflects the oxygen-carrying capacity of the blood. The normal hematocrit range for an adult female is 37% to 47%, and it may decrease slightly after delivery due to hemodilution. However, a drop in hematocrit of more than 10% from the baseline or below 30% indicates severe anemia and requires immediate treatment. Therefore, a drop in hematocrit of 6% since admission is a significant change that should be reported to the obstetrician as soon as possible.
Correct Answer is B
Explanation
Choice A) Increased urinary output: This is not a sign of sepsis in newborns. In fact, sepsis can cause reduced urinary output due to poor blood flow to the kidneys and dehydration.
Choice B) Hypothermia: This is a sign of sepsis in newborns. Sepsis can cause changes in temperature, often fever, but sometimes low temperature. Hypothermia can indicate a severe infection that affects the body's ability to regulate its temperature.
Choice C) Wakefulness: This is not a sign of sepsis in newborns. Sepsis can cause reduced activity and lethargy due to inflammation and organ dysfunction.
Choice D) Interest in feeding: This is not a sign of sepsis in newborns. Sepsis can cause reduced sucking and difficulty feeding due to poor appetite, nausea, vomiting, and abdominal distension.
