A nurse is teaching a client who is at 27 weeks of gestation and has pre-term labor about the signs and symptoms of true labor versus false labor.

Which of the following information should the nurse include in the teaching?

Instruct the client to empty her bladder.This is because a full bladder can interfere with the insertion of the needle and increase the risk of injury to the bladder or the uterus.Emptying the bladder also reduces discomfort during the procedure.

Choice A is wrong because administering tocolytic medication to stop contractions is not necessary before amniocentesis.Tocolytic medication can have side effects and should only be used when there is a clear indication of preterm labor.

Choice C is wrong because obtaining informed consent from the client is not a nursing action, but a medical one.The nurse can assist in providing information and answering questions, but the final consent should be obtained by the doctor who will perform the procedure.

Choice D is wrong because monitoring fetal heart rate and activity is not a specific action before amniocentesis, but a routine part of prenatal care.Fetal heart rate and activity can be affected by many factors, such as maternal position, fetal sleep cycle, or maternal blood sugar level.

Monitoring them before amniocentesis does not provide any useful information for the procedure.

Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that can cause renal impairment and elevated serum creatinine levels in both the mother and the fetus.This can lead to oligohydramnios, reduced fetal urine output, and fetal renal failure.

Therefore, the nurse should monitor the serum creatinine levels of the client and the fetus as a potential complication of indomethacin.

Choice A is wrong because indomethacin does not affect the platelet count.It may increase the risk of bleeding due to its antiplatelet effect, but it does not cause thrombocytopenia.

Choice C is wrong because indomethacin does not cause anemia or decrease the hematocrit.It may cause gastrointestinal bleeding or ulceration, which could lead to anemia, but this is not a common or direct effect of the medication.

Choice D is wrong because indomethacin does not cause hyperkalemia or increase the serum potassium levels.It may cause hyponatremia due to its effect on renal sodium excretion, but it does not affect potassium balance.
