C HAPTER 39: D RUGS U SED IN O BSTETRICS
Willihnganz: Clayton’s Basic Pharmacology for Nurses, 19th Edition
MULTIPLE CHOICE
1. A patient is a gravida 1, Rh -negative woman at a 28 weeks‘ gestation. the
father of her child is Rh positive. the mother is asking the nurse about the
effect on her unborn child of RhoGAM that has been ordered. What is the
nurse’s best repl y?
a. “Your child will do well after birth once transfusions are
administered. ”
b. “If the baby is Rh negative at birth, he or she will need RhoGAM
also.”
c. “RhoGAM kills antibodies you make, so your child will be
protected.”
d. “Your baby may be Rh positive and cause you to make antibodies.
These won’t affect this baby but could affect future children if
RhoGAM isn‘t given.”
ANS: D
An Rh-negative mother and an Rh -positive father have the potential for an
Rh-positive baby. At birth or during any time that the uterus ruptures, fatal
blood circulation can mix with maternal circulation, causing the mother to
produce antibodies (active immunit y) against Rh -positive blood. This would
cause Rh hemol ytic disease in children of future pregnancies. Rho(D)
immune globulin suppresses the stimulation of active immunity by Rh -
positive foreign red blood cells that enter mate rnal circulation at the time of
delivery, at the termination of pregnancy, or during a transfusion of
inadequatel y t yped blood. Transfusions may cause further problems. Immune
, globulin is given to the mother. the drug does not kill antibodies; it
suppresses production.

2. Which drug will the nurse administer to prevent neonatal conjunctivitis in
the newborn?
a. Silver nitrate
b. Dexamethasone
c. Erythrom ycin
d. Vitamin K
ANS: C
Erythrom ycin or tetracyclines are the drugs of choice because they prevent
neonatal conjunctivitis from Neisseria gonorrhoeae and chlamydial
ophthalmia neonatorum from Chlamydia trachomatis . Silver nitrate is an
outdated treatment for neonatal ocular infections. Dexamethasone is given for
lung development. Vitamin K is given for treatment of hemorrhage.
