Chorionic villus sampling: counseling your patient.

Chorionic villus sampling is a technique for prenatal genetic screening that has been widely publicized by the print and television media. Although not yet commonly available, women may seek additional information about the procedure from nurse practitioners. This article discusses the women for whom this procedure is most appropriate, the procedure's accuracy, sampling techniques, safety records and the procedure's accessibility and cost. The NP's role in counseling and anticipatory guidance is also discussed.

What's new in pregnancy tests.

Immunologically based pregnancy tests that will diagnose pregnancy even before the menstrual period is missed are now available. Nurses who deal with female patients in the reproductive years must be aware of these newer pregnancy tests now in use. Appropriate interpretation of pregnancy tests will aid women in early pregnancy to avoid potentially harmful radiation, drugs, or treatments.

Neonatal jaundice in the home: assessment with a noninvasive device.

Hyperbilirubinemia continues to be the major reason for hospital readmissions of neonates. This is particularly true for neonates who are discharged before the 72-hour physiological jaundice occurs. A small descriptive study reveals that use of a noninvasive bilirubinometer can be of assistance in screening for elevated bilirubin levels of newborns visited at home.

Factors related to sucking ability in healthy newborns.

OBJECTIVE: To identify maternal, infant, and environmental factors related to newborn sucking ability. DESIGN: Prospective, descriptive, exploratory study using a convenience sample. SETTING: Normal newborn nursery in an urban tertiary-care medical center. PARTICIPANTS: Two hundred three healthy newborns admitted to the normal newborn nursery after delivery. The newborns were between 30 minutes and 11 hours of age, and between 34 and 42 weeks gestation. MAIN OUTCOME MEASURES: This study examined 15 variables related to newborn sucking ability: infant state, age, gestational age, Apgar scores, birth weight, labor medications, type of delivery, elapsed time since last feeding, infant sex, perinatal complications, infant vital signs, birth resuscitation, clothing, room temperature, and length of labor. Sucking ability was measured by the Neonatal Oral Motor Assessment Scale (NOMAS). RESULTS: The variables of gestational age, weight, and state were positively correlated with sucking ability (NOMAS scores). Newborn's age postdelivery and minutes to the quiet alert state were inversely correlated with sucking ability. CONCLUSIONS: Newborn weight and gestational age are related to sucking ability. Younger newborns had better sucking ability than did older newborns.
