pathophysiology

2. Oxytocin= uterine contraction, producing uterine contractions; stimulates milk ejection by the breast. Nsg. Management: monitor I & O, assess labor contraction, watch for fetal distress, instruct patient to report increased blood loss; abdominal cramps; gradually increasing in intensity.

3. Magnesium sulfate= anticonvulsants, may decrease acetylcholine released by nerve impulses, but anticonvulsant mechanism is unknown. Nsg. management: monitor I & O, monitor for signs of magnesium toxity: disappearance of knee-jerk & patellar reflexes.

4. Hydralazine= antihypertensive, reduces blood pressure with reflex increases in heart rate, stroke volume, cardiac output. Nsg. Management: monitor v/s, monitor weight, I & O, advice patient to rise slowly & avoid sudden position change to prevent orthostatic hypotension, avoid alcohol during therapy.

5. Diazepam= for seizures, suppresses the spreads of seizure activity. Nsg. Management: monitor the type, duration, intensity & precipitating factor of seizures; inform patient that smoking may decrease diazepam effect; advise patient to avoid alcohol; avoid driving.

6. Metoprolol= antihypertensive, decreased blood pressure and reversal of cardiac arrhythmias. Nsg. Management: monitor v/s, I & O, advice patient to avoid driving.

7. Methyldopa= centrally acting drugs, resulting in decreased sympathetic outflow from the brain to the heart, kidneys & peripheral vasculature. Nsg. Management: monitor I & O; pulse & blood pressure regularly; tell patient to take weight daily; tell client that dry mouth can be relieved by hard candy, ice chips or sugarless gums.

8. Isoxsuprine HCL (duvadilan) = vasodilators, musculotropic vasodilator & its effect are not blocked by propanol. Nsg. Management: tell patient that direct acting vasodilator drugs can increase blood flow in normal resting skeletal muscles & brain.
