A nurse is reinforcing teaching with a client who is at 6 weeks of gestation. The client tells the nurse that she smokes one pack of cigarettes per day. The nurse should instruct the client that her newborn is at increased risk for which of the following clinical manifestations?

Choice A rationale: A positive contraction stress test warrants immediate attention and evaluation. Waiting for 24 hours to repeat the test could delay necessary interventions in case of fetal distress.
Choice B rationale: A positive contraction stress test indicates that there are late decelerations in the baby's heart rate during contractions, which may suggest fetal distress. In such cases, it is essential to admit the client to the hospital for further evaluation, monitoring, and appropriate management.
Choice C rationale: Checking the client's cervix for dilation is not the most appropriate action in response to a positive contraction stress test. Fetal well-being and assessment take priority in this situation.
Choice D rationale: A positive contraction stress test requires further action and should not be considered a routine finding. Proper management and evaluation are necessary when the test results are positive.

The correct answer is Choice B, the nipple line.

Choice A rationale: The axillae, or underarms, are not used to measure chest circumference in a newborn. This area does not provide an accurate or consistent measurement of chest size due to the positioning and movement of the baby’s arms.

Choice B rationale: The nipple line is the correct anatomical landmark to use when measuring chest circumference in a newborn. This line is typically used because it provides a consistent and accurate measurement. It is located at the level of the nipples, which is approximately at the mid-chest level. This location allows for a measurement that is representative of the chest size, as it is at the broadest part of the chest.

Choice C rationale: The lower ribcage border is not the correct landmark for measuring chest circumference in a newborn. This area is too low and would not provide an accurate representation of the chest size. The measurement taken at this location would be smaller than the actual chest size, as it is below the broadest part of the chest.

Choice D rationale: The sternal notch is not an appropriate landmark for measuring chest circumference in a newborn. The sternal notch is located at the top of the sternum, near the base of the neck. A measurement taken at this location would not accurately represent the size of the chest, as it is above the broadest part of the chest.
