Simulated
A primigravid client at 39 weeks' gestation is admitted to the hospital in active labor. On admission, the client's cervix is 6 cm dilated. After 2 hours of active labor, the client's cervix is still dilated at 6 cm with 100% effacement at -1 station. Contractions are 3 to 5 minutes apart, lasting 45 seconds, and of moderate intensity. The nurse determines that the client is most likely experiencing which of the following?
Correct answer
A
Rationale
Lack of cervical dilation (6 cm after 2 hours) despite adequate contractions suggests cephalopelvic disproportion, where the fetal head cannot pass through the pelvis. Prolonged latent phase occurs earlier, transition is at 8ÔÇô10 cm, and hypotonic contractions are weaker.
