Correct Answer :The dose of medication should be increased for pregnant clients
During pregnancy, a client's hepatic metabolism and glomerular filtration are increased. As a
result, the excretion rate is faster. The dose of a medication should be increased for the
medication action to be optimal. It is true that some medications should not be given to the
pregnant client, because of potential teratogenic effects on the fetus. The client should see
her health care provider if in doubt. The dose of a medication should be altered for a pregnant
client depending on the trimester she is in. How a medication affects the fetus depends on
the stage of development of the fetus and the dosage and strength of the medication
administered. During the first 3 to 8 weeks after fertilization, the major organs are developing,
and the dose of a medication should be decreased or withdrawn for pregnant clients.

does not cause fetal harm but may cause osteoporosis in the mother. Ethyl alcohol causes
drug dependence or alcohol withdrawal syndrome in neonates.
