| Cleft lip | A fissure in the upper lip that is due to failure of the left and right sides of the fetal lip tissue to fuse. |

| Hyperemesis gravidarum | Extreme, excessive, and persistent vomiting in early pregnancy that may lead to dehydration and malnutrition |
| Incompetent cervix | has an abnormal tendency to dilate and so may not be able to keep a fetus from being spontaneously aborted (miscarried) |
| Indirect Coombs' test | determines whether there are antibodies to the Rh factor in the mother’s blood |
| Kernicterus | A disorder that is due to severe jaundice in the newborn, with deposition of the pigment bilirubin in the brain that causes damage to the brain, potentially leading to athetoid cerebral palsy, hearing loss, vision problems, or mental retardation. |
| Kick counts | In the last trimester of your pregnancy, your doctor may ask you to keep track of the baby's movement every day. |

| RDS | Respiratory distress syndrome. Formerly known as hyaline membrane disease, a syndrome of respiratory difficulty in newborn infants caused by a deficiency of a molecule called surfactant. |
| Spina bifida | A major birth defect and a type of neural tube defect that involves an opening in the vertebral column caused by the failure of the neural tube to close properly during embryonic development |
| Thromboembolism | Formation in a blood vessel of a clot (thrombus) that breaks loose and is carried by the blood stream to plug another vessel |
