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.

Answer and Explanation

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: Taking the newborn to the nursery for the initial assessment. This is an ineﬀective intervention that disrupts parental atachment by separating the mother and the newborn. It also deprives the newborn of the benefits of skin to skin contact and breastfeeding.

Choice B Reason: Allowing the mother a chance to rest without the baby immediately after delivery. This is an unnecessary intervention that delays parental atachment by postponing the first contact between the mother and the newborn. It also ignores the mother's desire and readiness to hold and feed her baby.

Choice C Reason: Placing the newborn under a radiant warmer to do the initial assessment. This is an outdated intervention that hinders parental atachment by creating a physical barrier between the mother and the newborn. It also exposes the newborn to potential risks such as dehydration, hyperthermia, or eye damage.

Choice D Reason: Placing the newborn on the maternal abdomen and doing the initial assessment. This is because this intervention facilitates skin to skin contact, eye contact, and bonding between the mother and the newborn. It also enhances breastfeeding initiation, thermoregulation, and maternal-infant atachment.

A. Pulmonary edema. B. Convulsion (seizure). C. Renal failure. D. Retinal edema.

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.
