A nurse assesses a client in labor and suspects dysfunctional labor (hypotonic uterine dysfunction). The woman's membranes have ruptured and fetopelvic disproportion is ruled out.
Which intervention would the nurse expect to include in the plan of care for this client?
Encouraging the woman to assume a hands-and-knees position.
Providing a comfortable environment with dim lighting.
Administering oxytocin.
Preparing the woman for an amniotomy.
The Correct Answer is C
Choice A rationale
Encouraging a hands-and-knees position may help rotate a malpositioned fetus or relieve back pain, but it does not directly address hypotonic uterine dysfunction, which is characterized by weak, ineffective contractions. While it can improve maternal comfort and potentially aid in fetal descent if malpositioning is a contributing factor to slow labor progress, it will not augment the strength or frequency of contractions necessary for cervical dilation.
Choice B rationale
Providing a comfortable environment with dim lighting can promote relaxation and potentially enhance the progress of labor in cases of hypertonic uterine dysfunction (uncoordinated, painful contractions). However, in hypotonic dysfunction, the issue is a lack of adequate uterine muscle activity. While comfort measures are always important, they do not directly stimulate stronger contractions.
Choice C rationale
Administering oxytocin is the primary medical intervention for hypotonic uterine dysfunction. Oxytocin is a synthetic hormone that stimulates uterine smooth muscle to contract more frequently and with greater intensity. This augmentation of uterine activity aims to establish an effective labor pattern, leading to cervical dilation and fetal descent when fetopelvic disproportion has been ruled out.
Choice D rationale
Preparing for an amniotomy (artificial rupture of membranes) might be considered to augment labor if the membranes are intact. However, the question states the membranes have already ruptured. Amniotomy can sometimes stimulate contractions by releasing prostaglandins, but it is not the first-line intervention for established hypotonic dysfunction after membrane rupture, and oxytocin is generally more effective in this situation.

Correct Answer is B
Explanation
Choice A rationale
Placenta previa is a condition where the placenta implants in the lower part of the uterus, potentially covering the cervix. It typically presents with painless vaginal bleeding, especially in the later trimesters, and is not directly associated with sudden, intense abdominal pain and cessation of contractions during labor.
Choice B rationale
Uterine rupture is a serious complication of vaginal birth after cesarean (VBAC), especially with strong, frequent contractions. The sudden onset of intense abdominal pain and the cessation of contractions, along with fetal distress indicated by the absent fetal heart rate tracing, are classic signs of uterine rupture. The prior cesarean scar weakens the uterine wall, making it susceptible to tearing under the stress of labor.
Choice C rationale
A prolapsed umbilical cord occurs when the cord descends into the vagina ahead of the presenting part, potentially compressing the fetal blood vessels and causing fetal distress. While fetal heart rate abnormalities would be present, it is not typically associated with sudden, intense maternal abdominal pain and cessation of contractions.
Choice D rationale
Abruptio placentae is the premature separation of the placenta from the uterine wall. It can cause sudden abdominal pain, vaginal bleeding (though not always), and fetal distress. However, the cessation of uterine contractions is not a typical finding in abruptio placentae. Contractions may continue, although they might be accompanied by increased uterine tone.
Correct Answer is B
Explanation
Choice A rationale
This notation indicates three pregnancies (G3), one term birth (T1), two preterm births (P2), one abortion (A1), and three living children (L3). While the number of living children is correct, the total number of pregnancies is underestimated by excluding the current pregnancy.
Choice B rationale
This notation accurately reflects four pregnancies (G4: the elective abortion, the daughter, the twins, and the current pregnancy), one term birth (T1: the daughter born at 40 weeks), two preterm births (P2: the twin boys born at 34 weeks), one abortion (A1: the elective abortion), and three living children (L3: the daughter and the twin boys).
Choice C rationale
This notation indicates three pregnancies (G3), one term birth (T1), one preterm birth (P1), one abortion (A1), and three living children (L3). The number of preterm births is incorrect, as there were two preterm births (the twins).
Choice D rationale
This notation indicates four pregnancies (G4), one term birth (T1), one preterm birth (P1), one abortion (A1), and three living children (L3). The number of preterm births is incorrect, as there were two preterm births (the twins).
