What are nursing considerations for administering Pitocin | Do not bolus; keep on drip to regulate contractions; too much Pitocin can slow down labor; contractions may become too strong to allow perfusion to the fetus, increased risk of uterine rupture and pain |
A 40 week pregnant women presents to L&D, she is 2cm dilated and requesting pain medications; what should you explain to her about pain medications in the latent phase | Pain medications in the latent phase can slow or stop the progression of labor is given too early |
A 40 week pregnant women is 9cm dilated and requesting pain meds. What should you explain to her about pain meds during transition | Pain meds given during transition are unlikely to affect pain level at this point, and epidurals will be unlikely to kick in until after you have begun pushing |
