A tocolytic was administered to a woman to inhibit labor and maintain
pregnancy. Which nursing interventions would be beneficial to this client?
Select all that apply.
1
The drug should not be administered on a long term basis.
2
The drug should be continued after the contractions subside.
3
The client's vital signs and fetal heart rate should be monitored regularly.
4
The dose and route of administration should be determined.
5
The client should be placed in the right lateral recumbent position
Answer: 1, 3, 4
Long-term use of tocolytics may cause birth defects; therefore, tocolytics should not
be administered on a long-term basis. The vital signs and fetal heart rate should be
monitored regularly and closely to detect any abnormalities. The dose and route of
administration should be determined to avoid inaccurate dosing. The drug should be
discontinued after contractions cease. The client should be placed in the left lateral
recumbent position to increase blood flow to the fetus and to increase renal blood
flow.
Which drug may be used to treat postpartum hemorrhage?
1
Dinoprostone
2
Clomiphene
3
,Menotropins
4
Methylergonovine
Answer: 4
Methylergonovine is a drug of choice used to treat postpartum hemorrhage.
Clomiphene and menotropins are ovulation stimulants given to induce ovulation in
infertile women. Dinoprostone is used to induce cervical ripening and cause
termination of a pregnancy.
A nurse discusses the type of anesthesia that will be used for a vaginal birth
with a client who has class I cardiac disease. Which type of block is most
appropriate for this client?
1
Spinal
2
Epidural
3
Pudendal
4
Inhalation
Answer: 2
Epidural analgesia is used for a client with class I cardiac disease because the client
will be comfortable and have minimal stress when forceps or vacuum extraction is
used to shorten the second stage of labor. Spinal anesthesia is rarely used for a
birth. The anesthetic is injected into the subarachnoid space. Although a pudendal
block is adequate, epidural analgesia is more effective because less energy is
expended during labor and it provides more effective pain relief. Inhalation
anesthesia is not indicated for a vaginal birth for a client with class I cardiac disease;
it may cause respiratory difficulty.
Which drug is responsible for neonatal hypoglycemia?
1
Warfarin
2
Simvastatin
,3
Tolbutamide
4
Methimazole
Answer: 3
Tolbutamide is an oral hypoglycemic agent used in the treatment of type 2 diabetes
mellitus. It is known to have teratogenic effects like neonatal hypoglycemia. Warfarin,
a common blood thinner, may cause teratogenic effects such as skeletal and central
nervous system defects. Simvastatin, an HMG-CoA reductase inhibitor used for the
treatment of high cholesterol, may cause teratogenic effects like facial malformations
and severe central nervous system anomalies. Methimazole, an antithyroid drug
administered for the treatment of maternal hyperthyroidism, may cause teratogenic
effects like neonatal goiter, cretinism, and hypothyroidism.
A woman who underwent infertility treatment is pregnant with twins. Which
drug might have been responsible?
1
Raloxifene
2
Methylergonovine
3
Clomiphene
4
Dinoprostone
Answer: 3 Clomiphene is used as a part of infertility treatment to promote ovulation.
However, this drug can lead to multiple pregnancies. Raloxifene is prescribed to
prevent postmenopausal osteoporosis. Methylergonovine is prescribed to reduce
postpartum uterine hemorrhage. Dinoprostone is prescribed for the termination of a
pregnancy.
A lactating woman takes fluoxetine to treat depression. Her newborn
developed tremors, seizures, and fever. Which drug-induced physiologic
alterations may be responsible for the central nervous system effects of the
drug on the neonate?
, 1
Increase in fat content
2
Increase in protein binding
3
Immature blood-brain barrier
4
Delayed first stooling
Answer: 3 Many drugs are able to enter the neonate's brain due to the immature
blood-brain barrier causing central nervous system effects. Neonates have a low fat
content. Protein binding is decreased in neonates because the liver is immature and
produces fewer proteins. First pass elimination is decreased in neonates due to the
liver's immaturity.
A baby was born with a single-lobed brain and also had neural tube defects.
Which drug treatment in the client during her gestation might have caused this
condition?
1
Simvastatin
2
Isotretinoin
3
Carbamazepine
4
Cyclophosphamide
Answer: 1 Neural tube defects and single-lobed brains are teratogenic effects in a
newborn associated with simvastatin, an HMG-CoA reductase inhibitor. Isotretinoin
may cause central nervous system (CNS) defects. Carbama
A pregnant woman is administered medication to treat preterm labor that
requires a prescription for calcium gluconate to counter the effects of the
drug. Which drug was administered?
1
Nifedipine
