A nurse is caring for a client who had an amniocentesis at 16 weeks gestation and reports cramping and vaginal bleeding 24 hours later.
Which of the following actions should the nurse take first?
Administer Rho(D) immune globulin.
Monitor fetal heart rate
Assess maternal vital signs
Obtain an order for an ultrasound exam.
The Correct Answer is B
The correct answer is choice B. Monitor fetal heart rate.
This is because cramping and vaginal bleeding after amniocentesis are signs of possible complications such as miscarriage, preterm labor, or injury to the fetus.
Monitoring fetal heart rate can help assess the well-being of the fetus and detect any signs of distress.
Choice A is wrong because administering Rho(D) immunoglobulin is only necessary if the mother has Rh-negative blood and the baby has Rh-positive blood, which can cause Rh sensitization.
This is not given routinely to all women who have amniocentesis.
Choice C is wrong because assessing maternal vital signs is not the first priority when there is a risk of fetal compromise.
Maternal vital signs can be affected by many factors and are not specific indicators of fetal health.
Choice D is wrong because obtaining an order for an ultrasound exam is not the first action to take.
An ultrasound exam can help confirm the diagnosis of complications such as placental abruption or fetal demise, but it requires time and equipment that might delay immediate intervention.
Monitoring fetal heart rate can be done quickly and easily at the bedside.

Correct Answer is D
Explanation
This is a contraindication for the Contraction Stress Test (CST) because it increases the risk of infection and umbilical cord prolapse.
A CST is a test that measures the baby’s heart rate during uterine contractions induced by oxytocin or nipple stimulation.
Choice A is wrong because gestational diabetes is not a contraindication for the CST.
It is a condition that affects how the body processes glucose during pregnancy and may cause complications such as macrosomia (large baby), hypoglycemia (low blood sugar) or preeclampsia (high blood pressure and protein in urine).
Choice B is wrong because mild preeclampsia is not a contraindication for the CST.
It is a condition that causes high blood pressure and protein in urine after 20 weeks of pregnancy and may affect the placenta, kidneys, liver or brain.
Choice C is wrong because preterm labor is a relative contraindication for the CST, not an absolute one.
It means that the test may be performed if the benefits outweigh the risks, but it should be avoided if possible because it may trigger early labor or delivery.
Preterm labor is defined as regular uterine contractions with cervical changes before 37 weeks of pregnancy.
Normal ranges for blood pressure are below 120/80 mmHg, for glucose are 70-100 mg/dL (fasting) or below 140 mg/dL (2 hours after eating), and for protein in urine are less than 300 mg/24 hours.
Correct Answer is B
Explanation
Each of the five variables in a biophysical profile (BPP) is assigned a score of either 0 or 2 points, depending on whether it meets the criteria or not.
The five variables are:
Fetal breathing: 2 points if there is at least one episode of rhythmic breathing lasting at least 30 seconds within 30 minutes, 0 points otherwise.
Fetal movement: 2 points if there are at least three discrete body or limb movements within 30 minutes, 0 points otherwise.
Fetal tone: 2 points if there is at least one episode of extremity extension and subsequent return to flexion, 0 points otherwise.
Amniotic fluid volume: 2 points if there is a pocket of amniotic fluid measuring at least 2 cm in two perpendicular planes, 0 points otherwise.
Nonstress test: 2 points if there are at least two accelerations of fetal heart rate with or without fetal movement within 20 minutes, 0 points otherwise.
Choice A is wrong because each variable can have a score of either 0 or 2, not 0 or.
Choice C is wrong because there is no score of 1 for any variable.
Choice D is wrong because it is incomplete and does not provide the full range of possible scores.
