The nurse is reading the results of non-stress test (NST) strips completed that day. Which of the following strips meets the criteria for a reactive NST? Select one:<\/p>\n\n\n\n

A.
A fetal heart rate baseline of 140 with one acceleration to 155 for 15 seconds within 30 minutes.<\/p>\n\n\n\n

B.
A fetal heart rate baseline of 140 with two accelerations to 160 for 15 seconds within 20 minutes.<\/p>\n\n\n\n

C.
A fetal heart rate baseline of 130 with two accelerations to 135 for 15 seconds within 20 minutes.<\/p>\n\n\n\n

D.
A fetal heart rate baseline of 150 with two accelerations to 160 for 10 seconds within 20 minutes.<\/p>\n\n\n\n

The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is B<\/strong>: A fetal heart rate baseline of 140 with two accelerations to 160 for 15 seconds within 20 minutes.<\/em><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

A reactive non-stress test (NST)<\/strong> is a key tool used in prenatal care to assess fetal well-being by monitoring the fetal heart rate (FHR) in response to fetal movements. A reactive result indicates that the fetus is receiving adequate oxygenation and has a healthy autonomic nervous system response.<\/p>\n\n\n\n

Criteria for a Reactive NST:<\/h4>\n\n\n\n
    \n
  • Baseline FHR<\/strong>: The baseline fetal heart rate should fall within the normal range of 110 to 160 beats per minute.<\/li>\n\n\n\n
  • Accelerations<\/strong>: A reactive NST requires two or more accelerations<\/strong> within a 20-minute period. Each acceleration must meet the following:<\/li>\n\n\n\n
  • Duration<\/strong>: Last at least 15 seconds<\/strong>.<\/li>\n\n\n\n
  • Increase in heart rate<\/strong>: The fetal heart rate must increase by 15 beats per minute (bpm)<\/strong> or more above the baseline.<\/li>\n<\/ul>\n\n\n\n

    Review of Each Option:<\/h4>\n\n\n\n
      \n
    • Option A<\/strong>: This strip only shows one acceleration, whereas two accelerations are required for a reactive NST.<\/li>\n\n\n\n
    • Option B<\/strong>: This strip meets all the criteria for a reactive NST:<\/li>\n\n\n\n
    • The baseline FHR is 140, which is within the normal range.<\/li>\n\n\n\n
    • There are two accelerations<\/strong>, both lasting 15 seconds<\/strong>.<\/li>\n\n\n\n
    • The accelerations show an increase of 20 bpm<\/strong> (from 140 to 160), which meets the criteria for a reactive result.<\/li>\n\n\n\n
    • Option C<\/strong>: While there are two accelerations, they only increase by 5 bpm, which is below the required 15 bpm threshold for a reactive NST.<\/li>\n\n\n\n
    • Option D<\/strong>: Although there are two accelerations, they last only 10 seconds<\/strong>, which is below the required 15 seconds<\/strong> duration.<\/li>\n<\/ul>\n\n\n\n

      Thus, Option B<\/strong> best fits the criteria for a reactive NST and indicates fetal well-being.<\/p>\n","protected":false},"excerpt":{"rendered":"
