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 B
Explanation
Choice a) Document the event in the nurses' notes is incorrect because this is not a priority action for a neonate who is showing signs of hypoglycemia. Hypoglycemia is a condition where the blood glucose level is lower than normal, which can cause neurological and metabolic problems in newborns. Neonates of diabetic mothers are at higher risk of developing hypoglycemia due to increased insulin production and decreased glycogen stores.
Documenting the event in the nurses' notes is an important step, but it should be done after assessing and treating the neonate's condition.
Choice b) Test for blood glucose level is correct because this is the most important action for a neonate who is exhibiting symptoms of hypoglycemia. The nurse should use a heel stick or a cord blood sample to measure the blood glucose level of the neonate as soon as possible, as hypoglycemia can lead to serious complications such as seizures, coma, brain damage, or death if left untreated. The normal blood glucose range for a full-term neonate is 40 to 60 mg/dL in the first hour of life, and 50 to 90 mg/dL thereafter. A blood glucose level below 40 mg/dL indicates hypoglycemia and requires immediate intervention.
Choice c) Notify the clinician stat is incorrect because this is not the most urgent action for a neonate who is suffering from hypoglycemia. The nurse should notify the clinician after confirming the diagnosis of hypoglycemia and initiating treatment, such as feeding or administering intravenous glucose. The clinician may order further tests or treatments depending on the severity and cause of the hypoglycemia, but the nurse should not delay the initial management of the neonate's condition.
Choice d) Start an intravenous line with D5W is incorrect because this is not the first-line treatment for a neonate who has hypoglycemia. D5W stands for dextrose 5% in water, which is a solution that contains glucose and water. It can be used to treat hypoglycemia by providing a source of energy and fluid to the neonate. However, before starting an intravenous line with D5W, the nurse should first attempt to feed the neonate with breast milk or formula, as this can also raise the blood glucose level and provide other nutrients and antibodies. If feeding is unsuccessful or contraindicated, then the nurse should start an intravenous line with D5W as ordered by the clinician.
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.
