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:
A fetal heart rate baseline of 140 with one acceleration to 155 for 15 seconds within 30 minutes.
A fetal heart rate baseline of 140 with two accelerations to 160 for 15 seconds within 20 minutes.
A fetal heart rate baseline of 130 with two accelerations to 135 for 15 seconds within 20 minutes.
A fetal heart rate baseline of 150 with two accelerations to 160 for 10 seconds within 20 minutes.
The Correct Answer is B
Choice A Reason: A fetal heart rate baseline of 140 with one acceleration to 155 for 15 seconds within 30 minutes. This is an incorrect answer that indicates a non-reactive NST, which is a test that does not meet the criteria for a reactive NST. A non-reactive NST may suggest fetal hypoxia, distress, or sleep, but it does not necessarily indicate a problem. A non-reactive NST may require further testing or stimulation to elicit a reactive result.
Choice B Reason A fetal heart rate baseline of 140 with two accelerations to 160 for 15 seconds within 20 minutes. This is because this strip meets the criteria for a reactive NST, which is a non-invasive test that evaluates fetal well- being and oxygenation by measuring the fetal heart rate response to fetal movements. A reactive NST is defined as having at least two accelerations of the fetal heart rate that are at least 15 beats per minute above the baseline and last for at least 15 seconds within a 20-minute period.
Choice C Reason: A fetal heart rate baseline of 130 with two accelerations to 135 for 15 seconds within 20 minutes. This is an incorrect answer that indicates a non-reactive NST, which is a test that does not meet the criteria for a reactive NST. The accelerations in this strip are not sufficient in amplitude, as they are only 5 beats per minute above the baseline, instead of at least 15 beats per minute.
Choice D Reason: A fetal heart rate baseline of 150 with two accelerations to 160 for 10 seconds within 20 minutes. This is an incorrect answer that indicates a non-reactive NST, which is a test that does not meet the criteria for a reactive NST. The accelerations in this strip are not sufficient in duration, as they last only for 10 seconds, instead of at least 15 seconds.

Correct Answer is D
Explanation
Choice A Reason: "My baby will always be smaller than other babies his age." This is an incorrect answer that indicates a misconception or pessimism about SGA newborns. SGA newborns may not always be smaller than other babies their age, as they may catch up in growth and development with appropriate nutrition and care. SGA newborns may have different growth paterns depending on the cause and timing of their growth restriction.
Choice B Reason: "My baby will be okay as long as he has frequent feedings." This is an incorrect answer that indicates an oversimplification or optimism about SGA newborns. SGA newborns may not be okay with just frequent feedings, as they may have other problems or complications that require medical atention and intervention. SGA newborns may have increased nutritional needs and feeding difficulties due to low birth weight, poor suck-swallow coordination, or oral aversion.
Choice C Reason: "My baby will need to stay in the hospital until he weighs 5 pounds." This is an incorrect answer that indicates a misunderstanding or confusion about SGA newborns. SGA newborns may not need to stay in the hospital until they weigh 5 pounds, as they may be discharged earlier or later depending on their condition and readiness for home care. SGA newborns may have different criteria for discharge based on their gestational age, weight gain, feeding tolerance, temperature stability, and absence of complications.
Choice D Reason: "My baby can get cold easily, may have low blood sugar, and may have trouble breathing." This is because this statement by the parents indicates that they understand some of the common problems and complications that SGA newborns may face. SGA newborns are those who weigh less than the 10th percentile for their gestational age, which can be due to intrauterine growth restriction (IUGR) or constitutional factors. SGA newborns may have difficulties with thermoregulation, glucose metabolism, and respiratory function due to inadequate fat stores, glycogen reserves, and surfactant production.
Correct Answer is B
Explanation
Choice A Reason: Pulmonary edema is a condition where fluid accumulates in the lungs, causing shortness of breath and difficulty breathing. It can occur in preeclampsia due to increased blood pressure and fluid retention, but it is not a definitive sign of eclampsia.
Choice B Reason: Convulsion (seizure) is a sudden, involuntary contraction of muscles that can cause loss of consciousness, shaking, and twitching. It is the main symptom of eclampsia and distinguishes it from preeclampsia.
Choice C Reason: Renal failure is a condition where the kidneys fail to filter waste products from the blood, resulting in high levels of creatinine and urea. It can occur in preeclampsia due to reduced blood flow to the kidneys, but it is not a specific indicator of eclampsia.
Choice D Reason: Retinal edema is a condition where fluid leaks into the retina, causing blurred vision and flashes of light. It can occur in preeclampsia due to increased blood pressure and damage to the blood vessels in the eye, but it is not a characteristic feature of eclampsia.
