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?

Creatinine clearance.

Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits prostaglandin synthesis and suppresses uterine contractions.However, it can also causerenal failurein the fetus and the mother by reducing renal blood flow and glomerular filtration rate.

Therefore, the nurse should monitor the creatinine clearance, which is a measure of renal function, while the client is receiving this medication.

Choice A is wrong because indomethacin does not affect platelet count or coagulation.

Choice C is wrong because indomethacin does not affect liver function tests.

Choice D is wrong because indomethacin does not affect blood glucose levels.

Normal ranges for creatinine clearance are 88-128 mL/min for women and 97-137 mL/min for men.Normal ranges for platelet count are 150,000-450,000 cells/mm3.

Normal ranges for liver function tests vary depending on the specific test, but some common ones are: alanine aminotransferase (ALT) 7-55 U/L, aspartate aminotransferase (AST) 8-48 U/L, alkaline phosphatase (ALP) 45-115 U/L, total bilirubin 0.1-1.2 mg/dL.

Nitrazine paper test.

This test involves putting a drop of fluid obtained from the vagina onto paper strips containing nitrazine dye.

The strips change color depending on the pH of the fluid.The strips will turn blue if the pH is greater than 6.0, which indicates the presence of amniotic fluid.This test can help confirm rupture of membranes (ROM) in pregnancy, especially when preterm labor is suspected.

Choice B. Ferning test.This test involves examining a sample of vaginal fluid under a microscope and looking for a fern-like pattern that is formed by dried amniotic fluid crystals.This test can also help confirm ROM, but it is less reliable than the nitrazine test because other substances such as cervical mucus, semen, or blood can also cause ferning.

Choice C. Amniotic fluid index.This test involves measuring the amount of amniotic fluid in the uterus using ultrasound.This test can help assess the fetal well-being and detect conditions such as oligohydramnios (low amniotic fluid) or polyhydramnios (high amniotic fluid).This test cannot confirm ROM by itself, but it can be used in combination with other tests to evaluate the status of the pregnancy.

Choice D. Biophysical profile.This test involves using ultrasound and a fetal monitor to assess the fetal heart rate, breathing, movement, muscle tone, and amniotic fluid volume.
