A newborn develops jaundice that increases over the first week. Most of the bilirubin is indirect, and the red blood count is normal without signs of antibody reaction. The fater is blood type O positive and the mother blood type O negative. Mother recalls receiving a shot early in pregnancy "because of bad blood." The child has a tense abdomen with an enlarged liver, blood in the stool, and abdominal x-ray shows dilated loops of small intestine. The most likely diagnosis is:

Intestinal malrotation

A newborn has decrease muscle tone with a frog-leg posture, ears incompletely separated from the scalp, and undescended testes. He is normal after birth, but develops respiratory distress after four hours. Chest x-ray shows a homogenous, hazy infiltrate throughout the lung fields.

Possible fetal neural tube defect

Front 26

A newborn fails to breath at delivery and must be resuscitated. She is born after a long and difficult labor, with concerns about decreased oxygenation as manifest by slowing of her heart beat on the fetal monitor. The amniotic fluid is dark green at delivery. She develops severe respiratory distress, and a chest x-ray shows a fluffy infiltrate in her right lower lobe.

Back 26

Meconium aspiration

Front 27

A newborn develops jaundice that reaches a peak value at 3 days. All of the bilirubin is indirect, and the red blood count is normal without signs of antibody reaction. The father and mother both have blood type O negative. The most likely diagnosis is:

Back 27

Physiologic jaundice of the newborn

Front 28

Normal karyotype; amniotic alpha-fetoprotein (AFP) level uninterpretable unless correlated with population mean and gestational age.

A newborn develops jaundice that reaches a peak value at 3 days. All of the bilirubin is indirect, and the red blood count is slightly decreased with antibody detected on their surface. The father is blood type A negative and the mother blood type O negative. The most likely diagnosis is:
