The student nurse is preparing to assess the fetal heart rate (FHR). She has determined that the fetal back is located toward the client's left side, the small parts toward the right side, and there is a vertex (occiput) presentation. The student nurse should initially begin auscultation of the fetal heart rate in the mother's:

A) A stool softener as needed:
Fibrinogen levels are elevated during pregnancy as part of the body's natural response to the increased risk of bleeding at birth. While this helps to prevent hemorrhage, it also increases the risk of clot formation, which can lead to postpartum complications such as deep vein thrombosis (DVT) or pulmonary embolism (PE). To prevent these complications, one recommended strategy is to use a stool softener. This helps prevent constipation, which can strain the body and increase the risk of developing blood clots due to the Valsalva maneuver during straining. Stool softeners reduce the likelihood of this strain, supporting overall circulation and reducing the risk of clotting.

B) Urinate every two to three hours:
While frequent urination is important for general bladder health, particularly in the immediate postpartum period to avoid urinary retention, it is not directly related to preventing complications associated with elevated fibrinogen levels. Fibrinogen's main risk is related to clotting, and frequent urination does not affect this process.
C) Eat a diet high in protein:
While eating a balanced diet with adequate protein is essential for postpartum recovery and tissue healing, it does not directly address the increased fibrinogen levels or the potential for clotting. A high-protein diet does not significantly reduce the risks related to hypercoagulability during the postpartum period, which is primarily managed through careful monitoring and preventive measures such as using stool softeners or encouraging movement.

D) Walk:
While walking is beneficial for overall health and can help improve circulation, reducing the risk of DVT and promoting postpartum recovery, walking alone may not be sufficient to counteract the increased clotting risk from elevated fibrinogen levels. While movement is important to prevent clots, the use of stool softeners to prevent constipation is a more direct and targeted intervention for preventing strain, which could trigger clot formation. Therefore, walking, while helpful, is not the most specific measure to prevent complications related to increased fibrinogen.

A) Contractions that increase in intensity:
This is a hallmark sign of true labor. In true labor, contractions become progressively more intense, frequent, and regular. They also do not subside with rest or changes in activity. The intensity of contractions gradually increases as the cervix dilates and effaces, signaling the onset of labor.

B) Leakage of fluid from the vagina:
Leakage of fluid from the vagina, particularly if it is clear and odorless, is indicative of rupture of membranes, which can occur in true labor. If the membranes rupture and there is a continuous leakage of fluid, it is important for the client to contact the healthcare provider as it may signal the onset of labor. This is a significant sign of labor, especially if accompanied by contractions.

C) Increased bladder pressure:
Increased bladder pressure can occur in pregnancy, especially as the uterus grows and presses on the bladder. However, bladder pressure alone is not a definitive sign of true labor. It can also be a common complaint during late pregnancy, even before labor begins. This symptom would not be specific to true labor.

D) Blood-tinged vaginal mucus:
A bloody show, or blood-tinged mucus, is another classic sign of true labor. This happens as the cervix begins to soften, dilate, and efface, causing small blood vessels in the cervix to break. The bloody show is typically a pink or brownish mucus discharge and can occur just before labor starts, signaling that the cervix is changing in preparation for delivery.

E) Uterine contractions that decrease with rest:
This is a characteristic of false labor (Braxton Hicks contractions). In false labor, contractions tend to decrease or stop when the woman changes position, rests, or hydrates. On the other hand, in true labor, contractions persist and increase in intensity and frequency even with rest or hydration. Therefore, this is not a sign of true labor.
