COMPLETE QUESTIONS AND ANSWERS
(VERIFIED ANSWERS)
The three classic signs of placental separation after
delivery are
a. uterus falls, blood gushes, and cord lengthens
b. uterus rises, blood gushes, and cord lengthens
c. uterus rises, blood gushes, and cord shortens -
ANSWER-B
Extrusion of the placenta usually occurs within 30 minutes
of delivery. Slight tension is usually placed on the cord
during delivery of the placenta, but excessive tension may
result in tearing of the cord or inversion of the uterus and
must be avoided. The placenta should be carefully

examined after delivery to determine if it is complete as
placental fragments increase risk of maternal hemorrhage.
The segment can be placed on ice temporarily as cord
blood gas can be accurately assessed for 60 minutes. An
arterial sample is preferred over venous, but paired
sampling is recommended. A pH of 7.24 or less is
associated with neurological compromise. A base excess
of 12 mmol/L or more is predictive of motor or cognitive
impairment.
When eliciting the scarf sign in a neonate, the infant's
elbow crosses the midline of the chest, probably indicating
a
a. preterm infant.

b. term infant.
c. postterm infant. - ANSWER-A
At fullterm, the elbow should not cross the midline. For the
scarf test, the neonate should be placed supine. One arm
is grasped and the hand pulled toward the opposite
shoulder and then the position of the elbow is assessed in
relation to the midline of the chest.
Following birth, which hormone stimulates the alveolar
cells of the breast, promoting production of milk?
a. Estrogen
b. Prolactin
c. Progesterone - ANSWER-B
, 4|Page
which increases in response to the neonate's suckling.
Suckling also promotes release of oxytocin, which
promotes the letdown reflex by increasing contractibility of
the muscles of the mammary ducts. After milk production
is well established, prolactin levels decrease, and most
milk production is then facilitated by oxytocin. During
pregnancy, estrogen promotes proliferation of breast ducts
and progesterone the development of lobules and alveoli
Which anesthetic technique provides the best relief of pain
during labor and delivery?
a. Epidural
b. Spinal
c. Pudendal block - ANSWER-A
