Explanation
Choice D is correct. A reactive nonstress test indicates a normal result. In this finding, two or more fetal heart rate accelerations within a 20-minute period were observed. These accelerations should also be at least 15 beats per minute (bpm) and last longer than 15 seconds.
Choice A is incorrect. This is a nonreactive test result, which is concerning. A nonreactive test result is defined as fewer than two accelerations during a 20-minute period. The accelerations for a reactive NST should be at least 15 bpm lasting for longer than 15 seconds.
Choice B is incorrect. This range is indeed considered a normal fetal heart rate baseline, but it is not what defines a reactive NST. A fetus may have a normal baseline but still fail to meet criteria for reactivity (e.g., absence of accelerations).
Choice C is incorrect. Late decelerations present in a minimum of 50% of the contractions are a positive CST. A positive CST is not a reassuring finding and is considered an abnormal result.

Additional Info
✓ A fetal non-stress test (NST) is a prenatal test performed to evaluate the fetus's well-being.
✓ The test is typically recommended when there is a concern about fetal health, such as a high-risk pregnancy, decreased fetal movement, or other pregnancy complications.
✓ The test determines whether the placenta appropriately exchanges oxygen, carbon dioxide, nutrients, and waste products between maternal and fetal circulation.
✓ If there are no accelerations or the fetal heart rate is abnormal, further testing or interventions may be recommended to ensure the health and safety of the fetus.
