What are the functions of uterine contractions and the changes occurring during labor? (Questions 30-35)

Here are the answers to the questions:

30-Uterine contractions are useful for:

• Uterine contractions are essential for cervical dilation and for generating the force to push the fetus through the birth canal.
• The correct option is D.
• D) both answers are correct

31-During uterine contractions, fetal oxygenation:

• During a uterine contraction, blood flow to the placenta is temporarily reduced, leading to a transient decrease in fetal oxygenation.
• The correct option is A.
• A) decreases

32-In case of fetal bradycardia, it is necessary to:

• Fetal bradycardia can indicate fetal distress. Interventions include improving maternal oxygenation and changing the mother's position (e.g., left lateral decubitus) to enhance uteroplacental blood flow.
• The correct option is E.
• E) only the first two answers are correct

33-In case of normal labor, in a multiparous woman, the cervix dilates at a rate of at least:

• In multiparous women, the active phase of labor typically progresses at a rate of at least 1.5 cm/h to 2 cm/h.
• The correct option is C.
• C) 2 cm/h

34- The signs of imminent labor are:

• The urge to defecate, increasingly strong contractions, and opening of the anus can all be signs of progressing or imminent labor.
• The correct option is D.
• D) all of the above are correct

35- Normal uterine contractions last:

• During the active phase of labor, effective uterine contractions typically last between 40 and 60 seconds.
• The correct option is A.
• A) between 40 and 60 seconds

36- After the birth of the fetus, there is often:

• After the birth of the fetus, uterine contractions continue to facilitate the separation and expulsion of the placenta (third stage of labor). There is no period of rest where contractions subside, nor do they necessarily intensify compared to the second stage. Uterine atony is a complication, not a normal occurrence.
• The correct option is E.
• E) none of the answers are correct

37-After delivery, the uterine fundus is usually located:

• Immediately after the delivery of the placenta, the uterine fundus is typically firm and located midway between the navel (umbilicus) and the pubic symphysis.
• The correct option is D.
• D) midway between the navel and the pubic symphysis
