A nurse is explaining the purpose of a Contraction Stress Test (CST) to a pregnant client.

What does the CST aim to assess?

Fetal well-being.

Maternal blood pressure.

Placental function.

Amniotic fluid volume.

Answer and Explanation

The Correct Answer is A

A contraction stress test (CST) is performed near the end of pregnancy to determine how well the fetus will cope with the contractions of childbirth.

The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph.

A normal heartbeat is a good sign that the fetus will be healthy during labor.

Choice B is wrong because a CST does not measure maternal blood pressure.

Choice C is wrong because a CST does not assess placental function directly.

Choice D is wrong because a CST does not measure amniotic fluid volume.

Normal ranges for fetal heart rate are between 110 and 160 beats per minute.

Normal ranges for uterine contractions are between 2 and 5 contractions in 10 minutes, lasting less than 90 seconds each.

Correct Answer is A

Explanation

The woman should drink several glasses of water before the abdominal ultrasound procedure.

This is because a full bladder helps to push the intestines away and improve the visibility of the uterus and the fetus.

Drinking water also helps to avoid gas buildup in the abdomen, which could interfere with the sound waves.

Choice B is wrong because emptying the bladder would make it harder to see the uterus and the fetus.

Choice C is wrong because lying on the right side would not affect the quality of the ultrasound image.

Choice D is wrong because fasting is not necessary for an abdominal ultrasound, unless instructed by the doctor for a specific reason.

A. Administer Rho(D) immune globulin. B. Monitor fetal heart rate C. Assess maternal vital signs D. Obtain an order for an ultrasound exam.

Correct Answer is B

Explanation

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.
