B. Rapid intubation
C. Rapid induction

Answer 6

D

All treated like full stomachs

Question 7

Cholinesterase levels during pregnancy are…
A. Highest at term
B. Unchanged from normal levels
C. Increased
D. Decreased resulting in a clinically significant prolongation of amide type local anesthetics

Question 11

An intrapartum cardiotocography (CTG) finding of a late deceleration is:

A. Relieved by maternal position on left side
B. Caused by fetal head compression mediated by the vagus nerve
C. Caused by umbilical cord compression
D. Not worrisome if nonrecurring
E. Mostly due to placental insufficiency

Answer 11

E

Question 12

The most likely explanation of a deceleration on CTG is:

A. Maternal position on left side
B. Uterine hyperstimulation from cervical ripening agent (dinoprostone known as Cervidil)
C. Fetal head compression mediated by the vagus nerve
D. Umbilical cord compression

Answer 12

B
Decel = not getting enough oxygen/blood to them
Uterus is overstimulating/contracting just like a heart
