A nurse is preparing a client for a Contraction Stress Test (CST).

Which method can be used to induce uterine contractions during the test?

Nipple stimulation.

Intravenous oxytocin infusion.

Administering oral medications.

Applying warm compresses to the abdomen.

Answer and Explanation

The Correct Answer is B

This method can be used to induce uterine contractions during the test by stimulating the uterus with a hormone that causes contractions.

Oxytocin is also the hormone that naturally triggers labor contractions.

Choice A is wrong because nipple stimulation can also induce contractions, but it is not as reliable or controllable as oxytocin infusion.

Choice C is wrong because oral medications are not used to induce contractions during a CST.

Some medications may interfere with the test results or cause side effects.

Choice D is wrong because applying warm compresses to the abdomen does not induce contractions.

It may help with pain relief or relaxation, but it does not affect the uterus.

Normal ranges for uterine contractions during a CST are three contractions in 10 minutes, each lasting 40 to 60 seconds.

Normal ranges for fetal heart rate during a CST are 110 to 160 beats per minute, with no decelerations after contractions.

Correct Answer is B

Explanation

An amniotic fluid index (AFI) of 4 cm indicates oligohydramnios, which is a low amount of amniotic fluid.

Oligohydramnios can be caused by various factors, such as uteroplacental insufficiency, rupture of membranes, postterm pregnancy, fetal anomalies, or certain medications.

Oligohydramnios can lead to complications such as fetal death, intrauterine growth restriction, limb contractures, or delayed lung maturation.

Choice A is wrong because an AFI of 8 cm is within the normal range for amniotic fluid volume.

Choice C is wrong because a single vertical pocket of amniotic fluid measuring 3 cm is also within the normal range for amniotic fluid volume.

Choice D is wrong because a single vertical pocket of amniotic fluid measuring 5 cm is also within the normal range for amniotic fluid volume.

Normal ranges for AFI and single vertical pocket are > 5 to < 24 cm and ≥ 2 to < 8 cm, respectively.

A. 0 or. B. 0 or. C. 1 or. D. 1 or.

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.
