A nurse is explaining the purpose of a Doppler ultrasound blood flow analysis to a client who has intrauterine growth restriction (IUGR).

The nurse should inform the client that this test measures which of the following?

The velocity of blood flow in the uterine and fetal vessels.

The amount of amniotic fluid in the uterine cavity.

The pressure of blood flow in the umbilical cord.

The oxygen saturation level of fetal blo.

Answer and Explanation

The Correct Answer is A

A Doppler ultrasound blood flow analysis measures the velocity of blood flow in the uterine and fetal vessels.

This test can help assess the fetal well-being and oxygenation in cases of intrauterine growth restriction (IUGR).

Choice B is wrong because the amount of amniotic fluid in the uterine cavity is measured by ultrasound, not Doppler.

Choice C is wrong because the pressure of blood flow in the umbilical cord is not directly measured by Doppler, but rather inferred from the resistance index or pulsatility index.

Choice D is wrong because the oxygen saturation level of fetal blood is not measured by Doppler, but rather by fetal scalp sampling or pulse oximetry.

Correct Answer is B

Explanation

This is because cramping and vaginal bleeding after an amniocentesis may indicate a possible miscarriage or placental abruption, which can compromise fetal oxygenation and perfusion.

Monitoring fetal heart rate can help detect signs of fetal distress and guide further interventions.

Choice A is wrong because administering Rho(D) immune globulin is indicated for Rh-negative mothers who undergo amniocentesis to prevent isoimmunization, but it is not a priority action in this scenario.

Choice C is wrong because assessing maternal vital signs is important to monitor for signs of infection, hemorrhage, or shock, but it is not as urgent as monitoring fetal well-being.

Choice D is wrong because obtaining an order for an ultrasound exam can help confirm the diagnosis and evaluate the placenta and amniotic fluid, but it is not the first action to take in this situation.

A. No contractions were induced during the test. B. Late decelerations of the FHR were observed with at least 50% of contractions. C. The FHR remained stable throughout the test. D. The client experienced mild uterine cramping during the tes.

Correct Answer is C

Explanation

This means that the baby’s heart rate did not slow down after the contractions induced by oxytocin, which is a sign of normal fetal well-being.

A negative CST is normal and desirable.

Choice A is wrong because no contractions were induced during the test.

This means that the test was inconclusive and could not assess the baby’s response to stress.

Choice B is wrong because late decelerations of the FHR were observed with at least 50% of contractions.

This means that the baby’s heart rate slowed down and stayed slow after the contractions, which is a sign of fetal distress and hypoxia.

A positive CST is abnormal and concerning.

Choice D is wrong because the client experienced mild uterine cramping during the test.

This is not a relevant factor for interpreting the CST results, which depend on the FHR patterns.

Uterine cramping can be a side effect of oxytocin administration or nipple stimulation.
