Answer to Question 1

C
Feedback
A The fetoscope does not require the use of gel because ultrasonic transmission is
not used.
B Tocodynamometer does not require the use of gel. This device monitors uterine
contractions.
C Doppler is the only listed method involving ultrasonic transmission of fetal heart
rates; it requires use of a gel.
D The scalp electrode is attached to the fetal scalp; gel is not necessary.

Answer to Question 2

A
Feedback
A Each child born to a couple who carries an autosomal recessive trait has a 25
chance of having the disorder, because the child receives either a normal or an
abnormal gene from each parent.
B If one member of the couple has the autosomal recessive disorder, all of their
children will be carriers. If both parents are carriers, each child has a 50 chance
of being a carrier.
C The child has a 25 chance of being affected and a 50 chance of being a
carrier.
D Each child has the identical odds of being affected. Because both parents are
carriers, each child has a 25 chance of being affected, a 50 change of being a
carrier, and a 25 change of not having the gene transmitted.
