Final answer:
Immediate attention during pregnancy is needed if contractions occur every 5 minutes for over an hour, there's a sudden gush or leak of fluid, or there's vaginal bleeding or decreased fetal movement. These signs could indicate the onset of labor or a complication.
Step-by-step explanation:
The signs indicating the need for immediate attention during pregnancy include: Option 4: All of the above. Specifically, contractions every 5 minutes for more than 1 hour, a sudden gush or constant leak of fluid which may indicate rupture of membranes (ROM), and any sign of vaginal bleeding or decreased fetal movement. These symptoms could signal the onset of labor or potential complications that warrant immediate medical assessment and possible intervention. For example, true labor is characterized by regular contractions that do not subside with hydration or rest and become more frequent and powerful over time, potentially leading to dilation and effacement of the cervix.
A "bloody show" is a sign that labor may be imminent, and it's the result of a mucus plug in the cervical canal being expelled, indicating that the cervix is beginning to prepare for labor. Labor itself begins with the dilation of the cervix, followed by the birth of the baby and the delivery of the placenta. It's important for pregnant women to recognize these signs and seek immediate medical care to ensure the safety of both mother and baby.
