A nurse is teaching a client who is at 25 weeks of gestation and has pre-term labor about the purpose and side effects of magnesium sulfate therapy.

Which of the following statements by the client indicates an understanding of the teaching?

This is because assessing fetal heart rate is the most important action to take first when a client has prelabor rupture of membranes (PROM) at 34 weeks of gestation and oligohydramnios.Fetal heart rate can indicate fetal well-being, distress, or infection.Oligohydramnios can increase the risk of umbilical cord compression and fetal hypoxia.

Choice A is wrong because administering IV fluids is not the first priority in this situation.IV fluids may be given to prevent dehydration, enhance uterine blood flow, or augment labor, but they are not as urgent as assessing fetal heart rate.

Choice B is wrong because obtaining a urine specimen is not the first priority in this situation.A urine specimen may be obtained to check for infection, proteinuria, or glucose levels, but they are not as urgent as assessing fetal heart rate.

Choice D is wrong because inserting an indwelling urinary catheter is not the first priority in this situation.An indwelling urinary catheter may be inserted to monitor fluid balance, prevent bladder distension, or reduce the risk of infection, but they are not as urgent as assessing fetal heart rate.

Normal ranges for fetal heart rate are 110 to 160 beats per minute.Oligohydramnios is defined as an amniotic fluid index of less than 5 cm.

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.
