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 A
Explanation
Choice A Reason: Macrosomic fetus is a fetus that weighs more than 4000 grams or 8 pounds 13 ounces at birth. It is not a common complication of teenage pregnancy, but rather of maternal diabetes, obesity, or a history of large babies.
Choice B Reason: Preeclampsia is a condition characterized by high blood pressure and proteinuria in pregnancy. It can cause serious complications for both the mother and the baby, such as seizures, organ damage, growth restriction, and placental abruption. Teenage pregnancy is a risk factor for preeclampsia, especially if the mother is younger than 15 years old.
Choice C Reason: Inadequate nutritional status of mother is a condition where the mother does not consume enough calories, protein, vitamins, minerals, or fluids during pregnancy. It can affect the growth and development of the baby and increase the risk of low birth weight, preterm birth, and birth defects. Teenage pregnancy is a risk factor for inadequate nutritional status of mother, as teenagers may have poor dietary habits, eating disorders, or limited access to food.
Choice D Reason: Cephalopelvic disproportion is a condition where the size or shape of the baby's head or body is too large to fit through the mother's pelvis. It can prevent normal vaginal delivery and require cesarean section. Teenage pregnancy is a risk factor for cephalopelvic disproportion, as teenagers may have smaller or immature pelvises that are not fully developed.

Correct Answer is D
Explanation
Choice A Reason: Moderate amounts of deep red lochia. This is not a finding that would warrant further investigation, but rather a normal finding for the early postpartum period. Lochia is the vaginal discharge that occurs after delivery, which consists of blood, mucus, and tissue from the uterus. Lochia is usually deep red in color and moderate in amount for the first few days after delivery.
Choice B Reason: Sweating while afebrile. This is not a finding that would warrant further investigation, but rather a common occurrence in the postpartum period. Sweating is a mechanism of thermoregulation that helps the body eliminate excess fluid and electrolytes that were retained during pregnancy. Sweating does not necessarily indicate fever or infection.
Choice C Reason: Voiding 350 mL of blood-tinged urine. This is not a finding that would warrant further investigation, but rather an expected outcome for the postpartum period. Voiding large amounts of urine is normal in the postpartum period, as the body eliminates the excess fluid that was accumulated during pregnancy. Blood-tinged urine may be due to trauma or irritation of the urinary tract during labor or delivery, which usually resolves within a few days.
Choice D Reason: Heart rate of 115 beats/minute. This is because a heart rate of 115 beats/minute is higher than the normal range for an adult, which is 60 to 100 beats/minute. A high heart rate may indicate postpartum hemorrhage, infection, pain, anxiety, or dehydration. The nurse should further assess the client for other signs and symptoms of these conditions and notify the physician if necessary.
