A nurse is interpreting the results of a biophysical profile (BPP) for a client who is at 34 weeks of gestation.

The nurse should understand that each of the five variables is assigned a score of how many points?

0 or.

1 or.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

This test can detect genetic disorders.

Chorionic villus sampling (CVS) is a prenatal test that involves taking a sample of tissue from the placenta to test for chromosomal abnormalities and certain other genetic problems.

The placenta is a structure in the uterus that provides blood and nutrients from the mother to the fetus.

Choice A is wrong because CVS does not provide information on neural tube defects, such as spina bifida.

For this reason, women who undergo CVS also need a follow-up blood test between 16 to 18 weeks of their pregnancy to screen for neural tube defects.

Choice C is wrong because CVS can detect chromosomal abnormalities, but not all chromosomal abnormalities are genetic disorders.

For example, Down syndrome is a chromosomal abnormality that occurs randomly and is not inherited from the parents.

Choice D is wrong because CVS cannot detect Rh sensitization, which is a condition where the mother’s immune system produces antibodies against the fetus’s blood cells.

Rh sensitization can be detected by a blood test that measures the level of antibodies in the mother’s blood.

A. Fetal well-being. B. Maternal blood pressure. C. Placental function. D. Amniotic fluid volume.

Correct Answer is A

Explanation

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.
