A nurse is reviewing the ultrasound report of a client who is at 31 weeks of gestation and has pre-term labor.
Which of the following findings indicates oligohydramnios?
Amniotic fluid index of 4 cm
Amniotic fluid index of 8 cm
Amniotic fluid index of 12 cm
Amniotic fluid index of 16 cm
The Correct Answer is A
Amniotic fluid index of 4 cm indicates oligohydramnios, which means too little amniotic fluid. This can cause fetal growth restriction, cord compression, and congenital anomalies.
Choice B is wrong because amniotic fluid index of 8 cm is within the normal range of 5 to 25 cm.
Choice C is wrong because amniotic fluid index of 12 cm is also within the normal range and close to the median value of 14 cm.
Choice D is wrong because amniotic fluid index of 16 cm is also within the normal range and does not indicate oligohydramnios.

Correct Answer is A
Explanation
History of urinary tract infections.According to the Mayo Clinic, untreated vaginal infections, such as urinary tract infections or sexually transmitted infections, are risk factors for preterm labor.
These infections can cause inflammation and irritation of the cervix, which can trigger contractions and cervical dilation.
Choice B is wrong because maternal age of 25 years is not a risk factor for preterm labor.In fact, women younger than 18 or older than 35 are more likely to have a preterm delivery.
Choice C is wrong because singleton pregnancy is not a risk factor for preterm labor.On the contrary, being pregnant with twins, triplets, or more (called "multiple gestations") is associated with a higher risk of preterm labor and birth.
Choice D is wrong because cervical length of 3 cm is not a risk factor for preterm labor.A short cervix (less than 2.5 cm) or a cervix that shortens in the second trimester instead of the third trimester is a risk factor for preterm delivery.A normal cervical length ranges from 3 to 5 cm during pregnancy.
Correct Answer is D
Explanation
All of the above.The nurse should include all of these signs and symptoms in the teaching as they may indicate pre-term labor.Pre-term labor occurs when regular contractions begin to open the cervix before 37 weeks of pregnancy.
Choice A is wrong because decreased fetal movement is not a normal sign of pre-term labor, but it may indicate fetal distress or other complications.
Choice B is wrong because increased vaginal discharge is not a normal sign of pre-term labor, but it may indicate infection or rupture of membranes.
Choice C is wrong because pelvic pressure is not a normal sign of pre-term labor, but it may indicate cervical dilation or descent of the fetus.
