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: This is incorrect because Standard Precautions are a set of guidelines that apply to all patients, regardless of their infection status. They include using personal protective equipment, handling sharps and waste properly, and cleaning and disinfecting equipment and surfaces. However, they are not enough to prevent neonatal infection, as some pathogens can still be transmitted by contact or droplet.
Choice B: This is the correct answer because good hand hygiene is the most effective way to prevent the transmission of microorganisms that can cause neonatal infection. The nurse should wash their hands with soap and water or use an alcohol-based hand rub before and after touching the infant, the infant's environment, or any items that come in contact with the infant. The nurse should also educate the parents and visitors on the importance of hand hygiene and how to perform it correctly.
Choice C: This is incorrect because a separate gown technique involves wearing a clean gown for each infant and discarding it after use. This can help prevent cross-contamination between infants, but it does not eliminate the need for hand hygiene. The nurse should still wash their hands before and after wearing a gown, as well as before and after touching the infant or any items that come in contact with the infant.
Choice D: This is incorrect because isolation of infected infants involves placing them in a separate room or area with restricted access and using additional precautions based on the mode of transmission of the infection. This can help prevent the spread of infection to other infants, staff, or visitors, but it does not eliminate the need for hand hygiene. The nurse should still wash their hands before and after entering and leaving the isolation area, as well as before and after touching the infant or any items that come in contact with the infant.
Correct Answer is D
Explanation
Choice A) Obtain an oxygen saturation: This is not a priority action because it does not address the underlying cause of the respiratory distress, which is meconium aspiration. Meconium aspiration can cause airway obstruction, inflammation, infection, and pulmonary hypertension in the newborn. Oxygen saturation may be low, but it is not a reliable indicator of the severity of the condition.
Choice B) Stimulate the baby to increase respirations: This is not a priority action because it may worsen the respiratory distress by increasing the work of breathing and causing more meconium to be aspirated. Stimulation may also cause stress and hypoxia in the newborn.
Choice C) Prepare to initiate ECMO: This is not a priority action because it is a last resort treatment for severe cases of meconium aspiration syndrome that do not respond to conventional therapies. ECMO stands for extracorporeal membrane oxygenation, which is a form of life support that bypasses the lungs and provides oxygen to the blood.
ECMO has many risks and complications, such as bleeding, infection, and organ damage. It should only be used when other options have failed and with the consent of the parents.
Choice D) Notify the provider at once: This is the correct action because it allows for prompt assessment and intervention by the provider, who can initiate appropriate treatments for meconium aspiration syndrome. These may include suctioning of the airway, administration of antibiotics, surfactant, or inhaled nitric oxide, and mechanical ventilation . Early treatment can improve the outcomes and reduce the complications of meconium aspiration syndrome.
