The nurse knows that the occurrence of shoulder dystocia during labor is most likely related to which of the following?
Advance maternal age
Polyhydramnios
Macrosomia
Preterm birth
The Correct Answer is C
A. Advanced maternal age may increase the risk of certain pregnancy complications, but it is not specifically associated with shoulder dystocia. Other factors, such as fetal size, are more directly related to shoulder dystocia.
B. Polyhydramnios (excess amniotic fluid) can sometimes be associated with complications during labor, but it is not the primary risk factor for shoulder dystocia. The condition most often involves difficulties with the fetal position or size rather than the amount of fluid.
C. Macrosomia (a large baby, typically defined as a birth weight over 8 pounds 13 ounces or 4000g) is the primary risk factor for shoulder dystocia. Shoulder dystocia occurs when the baby’s shoulders become stuck during delivery, often due to the larger size of the baby. The baby’s shoulders may be too broad to pass through the birth canal easily, which increases the likelihood of this complication.
D. Preterm birth is not a significant risk factor for shoulder dystocia. Preterm babies are typically smaller and less likely to encounter the same birth canal obstruction issues associated with shoulder dystocia.

Correct Answer is C
Explanation
A. Oligohydramnios is more commonly associated with conditions like fetal growth restriction or placental insufficiency, and it is less common in twin pregnancies, which are actually more prone to polyhydramnios, especially in cases of twin-to-twin transfusion syndrome.
B. Chorioamnionitis is an infection of the fetal membranes, which can occur in any pregnancy, particularly with prolonged rupture of membranes, but it is not uniquely or especially linked to twin pregnancies.
C. Preeclampsia is correct. Women carrying twins (or other multiples) are at significantly higher risk for developing preeclampsia due to the increased placental mass and associated vascular demands. Nurses should be particularly vigilant in monitoring for signs like elevated blood pressure, proteinuria, edema, and headaches in these clients.
D. Post-term labor is less likely in twin pregnancies, as multiples are more often born preterm, not post-term, due to uterine overdistension and other complications.
Correct Answer is D
Explanation
A. A score of 7 would be given if the infant’s heart rate was 100, but with less than optimal responses for color, muscle tone, and respiratory effort. However, this baby demonstrates strong responses in all categories.
B. A score of 8would indicate that the baby has no signs of cyanosis and perfect responses in all categories, but since the infant has blue hands, it scores slightly lower (1 point less for color).
C. A score of 5 would indicate more significant distress, with poor color, respiratory effort, and muscle tone. This infant is showing good signs of adaptation.
D. The Apgar score is calculated based on five criteria: heart rate, respiratory effort, muscle tone, reflex irritability, and color. The infant in the scenario has:Heart rate of 100 (score 2)Pink body and blue hands (score 1 for color—because the baby is not fully pink, indicating some cyanosis in the extremities)Active motion (score 2 for muscle tone)Strong lusty cry (score 2 for reflex irritability/responsiveness to stimuli)
Good respirations (score 2)Adding these scores (2 + 1 + 2 + 2 + 2), the total is 9.
