A nurse is assessing a client who is 12 hours postpartum and received spinal anesthesia for a cesarean birth.
Which of the following findings requires immediate intervention by the nurse?

Choice A rationale

Edema, particularly peripheral edema, is a common clinical sign of preeclampsia. It results from fluid shifts due to increased vascular permeability and decreased plasma protein levels associated with the disease process.

Choice B rationale

Glycosuria, the presence of glucose in the urine, is not typically a symptom of preeclampsia. It is more commonly associated with gestational diabetes, a separate condition of pregnancy characterized by impaired glucose tolerance.

Choice C rationale

Proteinuria, the presence of significant amounts of protein in the urine (typically ≥300 mg in a 24-hour urine collection), is a hallmark sign of preeclampsia. It reflects glomerular endothelial damage and increased permeability.

Choice D rationale

Hypertension, defined as a blood pressure of ≥140/90 mmHg on two separate occasions at least 4 hours apart after 20 weeks of gestation, is a key diagnostic criterion for preeclampsia. It results from systemic vasoconstriction.

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.
