Q

OBG - 11.2
Which statement is true?
A) In the case of hypotonic inadequate contractions, the uterine basal tone is normal, the contractions occur less frequently, last for a short time with low intensity.
B) In the case of hypertonic inadequate contractions, low amplitude contractions occur frequently, their duration increases, the basal tone is increased.
C) In the case of normotonic inadequate contractions, contractions occur frequently, their amplitude and duration is inadequate.
D) In the case of normotonic inadequate contractions, the uterine basal tone is low.

A

ANSWER
B) In the case of hypertonic inadequate contractions, low amplitude contractions occur frequently, their duration increases, the basal tone is increased.
EXPLANATION
In the case of hypotonic inadequate contractions, the uterine basal tone is normal, the contractions occur less frequently, last for a short time with low intensity. In the case normotonic inadequate contractions, contractions occur infrequently, are ineffective and duration are inadequate but uterine tone is normal.

Q

OBG - 11.3
Which statement is false?
A) Hyperkinetic disorders (too strong contractions) may be caused by increased excitability if uterine muscles.
B) Hyperkinetic disorders (too strong contractions) may be caused by the partial placental abruption.
C) Hyperkinetic disorders (too strong contractions) may be caused by placenta previa
D) Hyperkinetic disorders (too strong contractions) may be caused by cephalopelvic disproportion

A

ANSWER
C) Hyperkinetic disorders (too strong contractions) may be caused by placenta previa
EXPLANATION
Hyperkinetic abnormalities (too strong contractions) can caused by hyperactivity of uterine muscles, by placental abruption or by cephalopelvic disproportion in order to overcome that events. Placenta previa do not cause hyperkinetic abnormalities.

Q

OBG - 11.5
What is the Bandl contraction ring?
A) Muscle ring located at the border of the cervix and corpus uteri
B) Retraction ring visible at the border of the active-passive section of the uterus during labor
C) The muscle ring in the vaginal vestibule during labor
D) The contraction ring at the upper third of the vagina when the cervix is fully dilated

A

ANSWER
B) Retraction ring visible at the border of the active-passive section of the uterus during labor
EXPLANATION
As a result of the thinning of the lower uterine segment and the concomitant thickening of the upper, the boundary between the two is marked by a ridge on the inner uterine surface, the physiological retraction ring. When the thinning of the lower uterine segment is extreme as in obstructed labor or cephalopelvic disproportion the ring is very prominent forming a pathological retraction ring also known as a Bandl ring.

Which is characteristic for a partial abruption of the placenta?
A) uterine tenderness “deck hard”
B) heavy fresh bleeding occurs from the uterus
C) the amniotic fluid is pure
D) does not involve blood clotting disorder

A

ANSWER
A) uterine tenderness “deck hard”
EXPLANATION
Symptoms of placental abruption are sudden abdominal pain, uterine tenderness, the amount of vaginal bleeding can vary greatly, and doesn’t necessarily correspond to how much of the placenta has separated from the inner wall of the uterus. Amniotic fluid may be bloody and blood clotting problems (disseminated intravascular coagulation) occur more often.

Q

OBG - 11.16
A patient with 39 weeks pregnancy has one cesarean section in her history. The premature rupture of membranes occurs without contractions, the cervix is dilated to 3 cm. What to do?
A) Immediately intravenous administration of 5NU Oxytocin to cause contractions
B) In certain cases Oxytocin infusion can be used to amplify contractions
C) If the contractions are regular and the anatomical findings progress,but the first stage last more than 6 hours cesarean section should be performed
D) Immediate cesarean section

A

ANSWER
B) In certain cases Oxytocin infusion can be used to amplify contractions
EXPLANATION
Iv. Oxytocin administration is allowed in certain cases after previous cesarean section. Provided there are no contraindications, a woman with 1 previous transverse low -segment cesarean section should be offered a trial of labour. Induction of labour with oxytocin may be associated with an increased risk of uterine rupture and should be used carefully after appropriate counselling. Administration of iv. 5 NU (national unit) Oxytocin is not recommended during the first stage of birth to cause contraction, and the first stage can be last more than 6 hours.

What should be done if the fetus’s arms are extended above the head during vaginal delivery?
A) Using the proper maneuver we deliver the arms of the fetus. (right arm with right hand, left arm with left hand)
B) Immediate cesarean section
C) By pulling the fetus, we change the position of the arms and deliver the fetus
D) We push the fetus back into the uterus, thereby we change the position of the arms and then continue the vaginal delivery

A

ANSWER
A) Using the proper maneuver we deliver the arms of the fetus. (right arm with right hand, left arm with left hand)
EXPLANATION
One or both fetal arms occasionally is found above the head, in this situation, delivery is more difficult. Differents maneuver should be performed such as „Müller maneuver” to deliver the arms. Any other manipulation such as pulling the fetus hard or pushing back can cause serious life-threating injuries.

Possible reason for breech presentation:
A) Oligohydramnion
B) Deformation of the uterine cavity
C) Macrosomia
D) Premature birth
E) All of the above

A

ANSWER
E) All of the above
EXPLANATION
The major predisponding to breech presentation is prematurity. However fetal structural anomalies (hydrocephalus, macrosomy) may restrict the ability of the fetus to present as a vertex. Other etiologic factors include uterine anomalies, multiple gestation, hydramnios, contracted maternal pelvis can cause breech presentation.

Q

OBG - 11.40
Condition for vacuum extraction:
A) Fully dilatated cervix
B) Fetal head engaged into the pelvis
C) Matured fetus
D) Membrane is ruptured
E) All of the above

A

ANSWER
E) All of the above
EXPLANATION
To perform vacuum extraction the cervix must be fully dilatated, membranes ruptured, and the fetal head engaged into the pelvis. There must be no doubt regarding the position of the fetal head. The vacuum extractor is contraindicated in preterm delivery because the preterm fetal head is more prone to injury from the suction cup.

31
Q

OBG - 11.41
For operative vaginal delivery, forceps should be chosen in the following cases:
A) In the case of a large fetus, to overcome cephalopelvic disproportion
B) In the case of premature birth
C) Dorsoanterior transverse lie
D) Umbilical cord prolapse
E) Dorsoposterior transverse lie

A

ANSWER
B) In the case of premature birth
EXPLANATION
Vaginal operativ delivery is recommended in case of intrapartum fetal distress, or in preterm birth. The vacuum extractor is contraindicated in preterm delivery because the preterm fetal head is more prone to injury from the suction cup, but forceps delivery is recommended. Cesarean section should be perform by transverse lie or by detection of prolapsed umbilical cord

Indication for cesarean section, except:
A) Previous myomectomy / uterine surgery
B) Cephalopelvic disproportion
C) Placenta praevia centralis
D) Low placental implantation
E) Previous two cesarean sections in anamnesis

A

ANSWER
D) Low placental implantation
EXPLANATION
An absolute indication for cesarean delivery is a previous incision through the myometrium of the uterus. All pregnancies complicated with placenta previa should also be delivered by cesarean. Other indications are: dystocia, repeat cesarean section, breech presentation or fetal distress. Low implantation of the placenta can predispose to postpartum hemorrhage but it does not an indication for cesarean section.

B) perinatal mortality is two-three times higher
C) fetal movement may decrease
D) often the accurate dating of the gestation is uncertain

A

ANSWER
A) delivery happen between the 41st-42th gestational week
EXPLANATION
Postterm pregnancy is one that persist beyond 42 weeks (294 days) from the onset of the last normal menstrual period. Perinatal mortality is two three times hihgher in these prolonged gestation. Oligohydramnion, decreased fetal movement can occur, and often the accurate dating of gestation is in background. The importance of accurate (early) assessment of gestational age is required to avoid unreal prolonged gestation.

B) In the case of brow presentation, the guiding point is the center of the forehead
C) The presenting diameter is the saggital suture
D) With an external examination, there is an indenture between the extended fetal head and the back

A

ANSWER
C) The presenting diameter is the saggital suture
EXPLANATION
Brow presentation occurs when presenting part of the fetus is between facial orbits and anterior fontanelle. The presenting diameter is the supraoccipitomental diameter which makes vaginal delivery impossible

45

Q

OBG - 11.56
In the case of transversal lie, the proper care:
1) In case of membranes rupture, an immediate caesarean section should be performed.
2) In case of intact membrane, waiting until the 36th pregnancy week is allowed.
3) At 34 weeks of pregnancy, tocolysis should be managed in case of contractions.
4) In the case of a prolapsed fetal arm, an external positioning of the fetus is to be managed, in case of failure an urgent caesarean section is to be performed.
5) In the case of regular contractions, at 38th week of gestation vaginal delivery can be managed, in case of failure cesarean section should be performed.

C) 2nd and 4th answers are correct
D) all of the answers are correct
E) only the 5th answer is correct
F) none of the answers are correct

A

ANSWER
A) 1st, 2nd and 3rd answers are correct
EXPLANATION
1.After rupture of the membranes, if labor continues, the fetal shoulder is forced into the pelvis and the corresponding arm frequently prolapses. The uterus then contracts vigorously in an unsuccesful attempt to overcome the obstacle. The situation is referred to as a neglected transverse lie. The only appropiate method is immediate cesarean section. 2. , 3. By intact membrane with a preterm pregnancy, the goal is to attempt to obtain fetal maturation (until 36th gestational week) even with tocolysis without compromising the other’s health.

Possible treatment in uterine atony:
1) Ligation of hypogastric artery
2) Manual revision (retained placental tissue removal)
3) Bimanual compression and massage of the uterine corpus
4) Supracervical or total hysterectomy
5) Administration of iv. infusion, transfusion of packed red blood cells and FFP

C) 2nd and 4th answers are correct
D) all of the answers are correct
E) only the 5th answer is correct
F) none of the answers are correct

A

ANSWER
D) all of the answers are correct
EXPLANATION
In case of uterine atony rapid continous iv. infusion, transfusion of packed red blood cells, FFP should be given. Bimanual compression and massage of the uterine corpus cause the uterus contract. Packing the uterine cavity (Dührssen tamponade) can control postpartum hemorrhage. Ligation of the uterine arteries and other operative intervention such as supracervical or total hysterectomy are definitive therapies

Q

OBG - 11.59
Absolute indication of cesarean section in twin pregnancies:
1) Breech-Vertex presentation of twins (twin “A” is in breech, twin “B” is in cephalic presentation)
2) Vertex-vertex presentation in term
3) Premature twins in transverse-transverse presentation
4) Vertex-Breech presentation (twin A in cephalic, twin B in breech presentation)
5) Multiparous patient, vertex-vertex presentation (twin A in cephalis, twin B in cephalic presentation)

F) none of the answers are correct

A

ANSWER
B) 1st and 3rd answers are correct
EXPLANATION
Vertex (twin A)-vertex (twin B) twins are managed similarly to singleton vertex presentation. Increased risk of fetal injury exist with delivery of breech fetus, breech-breech and breech- vertex twins are usually delivered by cesaresan section. Preterm delivery or transverse lie of both fetuses are also indication of cesarean section

Q

OBG - 11.64
Which statements are true for face presentation?
1) incidence is about 1 in 500 deliveries
2) when delivered spontaneous vaginal delivery, perinatal morbidity is similar to vertex presentation
3) if the guiding point (mentum) rotates posteriorly, vaginal delivery is impossible
4) vacuum –assisted vaginal delivery is recommended

A) 1st, 2nd and 3rd answers are correct
B) 1st and 3rd answers are correct
C) 2nd and 4th answers are correct
D) all of the answers are correct
E) none of the answers are correct

A

ANSWER
A) 1st, 2nd and 3rd answers are correct
EXPLANATION
The incidence about face presentation is about 1 in 500 deliveries. If the mentum rotates posteriorly, the fetal head will be unable to extend farther to complete the expulsive process and the delivery must be accomplished by cesarean section. When delivered by spontaneous vaginal delivery, perinatal morbidity and mortality are similar those for vertex presentation. Vacuum assisted vaginal birth is absoulte contraindicated in face presentation.
