The Correct answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is A<\/strong>: An increase in fetal heart rate to 150\/min above the baseline of 140\/min lasting 10 seconds in response to fetal movement within a 40-min testing period.<\/p>\n\n\n\n A nonstress test (NST) is a common procedure used to assess fetal well-being during pregnancy, particularly in the antepartal period. It measures the fetal heart rate (FHR) in response to fetal movements. A typical NST is considered reactive when it shows at least two accelerations in the FHR of at least 15 beats per minute above the baseline, lasting for at least 15 seconds within a 20-minute period.<\/p>\n\n\n\n In this scenario, the finding in option A indicates a fetal heart rate increase to 150 beats per minute (bpm) from a baseline of 140 bpm. While this represents an acceleration, it only lasts for 10 seconds. This duration is insufficient for a reactive NST, which typically requires accelerations of at least 15 seconds. Additionally, an increase to 150 bpm may suggest potential fetal distress, especially if it occurs with minimal or no movement, warranting further evaluation and diagnostic testing.<\/p>\n\n\n\n Option B describes a situation without late decelerations during uterine contractions, which is a reassuring finding indicative of good fetal well-being. Option C reflects no late decelerations with contractions, supporting normal fetal status as well. Option D, which notes irregular contractions that are not felt by the client, generally does not indicate a problem unless there are additional concerning factors.<\/p>\n\n\n\n Thus, while options B, C, and D suggest normal findings or situations that do not require immediate concern, option A raises red flags regarding the adequacy of fetal oxygenation and suggests that further diagnostic testing\u2014such as a biophysical profile or additional fetal monitoring\u2014may be needed to ensure fetal well-being.<\/p>\n","protected":false},"excerpt":{"rendered":" A nurse is assessing the results of a nonstress test for an antepartal client at 35 weeks of gestation.Which of the following findings should indicate to the nurse the need for further diagnostic testing?
