A nurse is caring for a client who is at 35 weeks of gestation and has pre-term labor with intact membranes and no signs of infection.
The provider prescribes indomethacin to inhibit prostaglandin synthesis and suppress uterine contractions.
Which of the following laboratory tests should the nurse monitor while the client is receiving this medication?
Platelet count
Creatinine clearance
Liver function tests
Blood glucose levels
The Correct Answer is B
Creatinine clearance.
Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits prostaglandin synthesis and suppresses uterine contractions. However, it can also cause renal failure in 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.

Correct Answer is A
Explanation
Assess fetal heart rate and activity.
The nurse should identify that a client who reports a sudden gush of fluid from her vagina is at risk forpremature rupture of membranes (PROM), which can lead toinfection,cord prolapse, andfetal distress.Therefore, the priority action is to assess the fetal heart rate and activity to monitor for signs of hypoxia or distress.
Choice B is wrong because performing a nitrazine test on the fluid is not the first action.A nitrazine test can confirm the presence of amniotic fluid by detecting its alkaline pH, but it is not as urgent as assessing the fetal well-being.
Choice C is wrong because administering oxytocin (Pitocin) IV infusion is contraindicated in this situation.Oxytocin is used to induce or augment labor, but it can causeuterine hyperstimulation,fetal distress, andplacental abruptionif given to a client who has PROM.
Choice D is wrong because placing the client in Trendelenburg position is not recommended for a client who has PROM.Trendelenburg position can increase the risk ofcord prolapseandaspirationin this situation.
Correct Answer is C
Explanation
To promote fetal lung maturity.Betamethasone (Celestone) is a type of corticosteroid that can help reduce the risk of respiratory distress syndrome and other complications in preterm infants by accelerating the development of their lungs.It is recommended for pregnant women between 24 0/7 weeks and 36 6/7 weeks of gestation who are at risk of preterm delivery within 7 days.
Choice A is wrong because betamethasone does not suppress uterine contractions.
It has no effect on the cause of preterm labor.
Choice B is wrong because betamethasone does not prevent infection.
It may actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because betamethasone does not reduce maternal blood pressure.
It may actually cause hypertension and hyperglycemia as side effects.
