1. The nurse is monitoring a client who is receiving oxytocin (Pitocin) to induce labor. Which assessment finding would cause the nurse to immediately discontinue the oxytocin infusion? 1.Fatigue 2.Drowsiness 3.Uterine hyperstimulation 4.Early decelerations of the fetal heart rate Rationale: Often used to induce labor. High doses are often used for uterine hyperstimulation & C/S births. ADVERSE EFFECTS: Hyperstimulation of uterine contractions & non-reassuring fetal HR DISCONTINUE 2. A pregnant client is receiving magnesium sulfate for the management of preeclampsia. The nurse determines that the client is experiencing toxicity from the medication if which finding is noted on assessment? 1.Proteinuria of 3 + 2.Respirations of 10 breaths/ minute 3.Presence of deep tendon reflexes 4.Serum magnesium level of 6 mEq/ L Rationale: Mg TOXICITY RESP. DEPRESSION, LOSS OF TENDON REFLEXES & SUDDEN DECLINE IN FETAL HR, MATERNAL HR, & BP caused by Mg tx. Must remain within therapeutic serum levels 4–7.5 mEq/L. Proteinuria 3+ is expected in a pt w/ preeclampsia.
