HERRERA, Perry Lee B. BSN III – A3a
Contraindication
Nursing Responsibility >Be alert for adverse reactions and drug interactions. >This drug should be used extremely carefully because of it's potent vasoconstrictor action. I.V. use may induce sudden hypertension and cerebrovascular accidents. As a last resort, give I.V. slowly over several minutes and monitor blood pressure closely.
Generic Name (Brand Name) Oxytocin
Drug Classification & Indication PC: Exogenous Agent TC: oxytocic, lactation stimulant Indication: Induction of labor at term; control of postpartum bleeding; adjunctive therapy in management of abortion

Mechanism of Action
Adverse Reaction
Contraindication
Nursing Responsibility
Oxytocin ↓ Causes potent and selective stimulation of uterine and mammary gland smooth muscles ↓ producing sustained contractions ↓ Induces labor and milk ejection and reduces post partum bleeding
Cardiovascular: hypertension; increased heart rate, systemic venous return, and cardiac output, and arrhytmias
> Contraindicated in patients hypersensitive to the drug or any of its component.
> Monitor and record uterine contractions, heart rate, BP, intrauterine pressure, fetal heart rate, and blood loss q15.
CNS: seizures, coma from water intoxication Gastrointestinal: Nausea, vomiting, GU: titanic uterine contractions, abruption placentae, impaired uterine blood flow, pelvic hematoma Hematologic: afibrinogenemia Respiratory: anoxia, asphyxia
HERRERA, Perry Lee B. BSN III – A3a
> Also contraindicated in cephalopelvic disproportion or delivery that requires conversion, as in tranverse lie; in fetal distress when delivery isn’t imminent; in prematurity and in severe toxemia, hypertonic uterine patterns, total placenta previa or vasa previa.
> Also contraindicated in fetal distress.
>Be alert for adverse reaction >Monitor I/O. Antidiuretic effect may lead to fluid overload, seizures, and coma >never give oxytocin simultaneously by more than one route. >have 20% solution magnesium sulfate available for relaxation of the myometrium. >If contractions are less than 2 minutes apart, if they’re above 50mm Hg ,or if they last 90seconds or longer, stop infusion, and turn patient on her side, and notify prescriber

Adverse Reaction
Contraindication
CNS: dizziness, headache, malaise

Dosage, Route, Frequency IV: 1 mg/ml
Mechanism of Action
Adverse Reaction
Contraindication
Nursing Responsibility
HBB ↓ Inhibits muscarinic actions of acetylcholine in the ANS ↓ Affecting neural pathway ↓ Relieves spasticity, nausea and vomittin; reduces secretions; and blocks cardiac vagal reflexes.

Dosage, Route, Frequency 5 mg/dose then 5-10 mg every 20-30 minutes as needed.
Mechanism of Action Hydralazine ↓ Directly relaxes arteriolar smooth muscle ↓ Vasodilaion ↓ Lowers Blood Pressure
Adverse Reaction
Contraindication
Nursing Responsibility
CNS: peripheral neuritis, headache, dizziness
Contraindicated to pt.s hypersensitive to the drug and any of its component and in those with coronary artery disease or mitral valvular rheumatic heart disease.
