The nurse is evaluating the new mother's knowledge about appropriate infant bottle feeding techniques. Which statement by the client reassures the nurse that correct learning has taken place?

A. Chorionic villus sampling (CVS) is typically performed between 10 and 13 weeks of gestation. It involves obtaining a small sample of placental tissue (chorionic villi) to test for chromosomal abnormalities, genetic disorders, and certain metabolic conditions. Performing the procedure within this timeframe allows for early detection of fetal abnormalities, which gives the parents more options for pregnancy management.

B. By 18 weeks of gestation, CVS is no longer indicated, as amniocentesis becomes the preferred procedure for prenatal genetic testing at mid-pregnancy. Performing CVS this late would increase the risk of complications without providing additional benefit.

C. At 6 weeks, the placenta is not sufficiently developed to obtain an adequate sample of chorionic villi. Attempting CVS this early carries a higher risk of procedure failure and complications, including miscarriage.

D. At 4 weeks, the embryo is too small and placental development is insufficient for CVS. Genetic testing is not feasible at this stage, and attempting it would be unsafe.

A. This is not necessary in this situation because a heart rate of 130 beats per minute is within the normal range for a term newborn. Immediate notification of the provider is required only for abnormal heart rates (tachycardia >160 bpm, bradycardia <100 bpm), irregular rhythms, or other signs of compromise, such as pallor, cyanosis, or poor perfusion.

B. Verification may be useful when an abnormal or unexpected finding occurs, but it is not required for a heart rate that is clearly within the normal range. Routine newborn assessments are reliable when performed properly.

C. The normal resting heart rate for a full-term newborn ranges from 110 to 160 beats per minute. A heart rate of 130/min falls squarely within this range, indicating adequate cardiovascular function. Documentation should include the apical heart rate, method of measurement, time of assessment, and any relevant observations (e.g., skin color, activity, respiratory effort). Proper documentation ensures continuity of care and provides a baseline for ongoing assessments.

D. This is unnecessary. There are no signs of distress or abnormal findings in this scenario that would warrant NICU admission. Routine monitoring and care in the newborn nursery or with the mother are appropriate.
