The nurse is aware that which of the following magnesium sulfate levels should be reported to the MD and is most likely to result in toxicity?
61 mEq/L.
70 mEq/L.
29 mEq/L.
45 mEq/L.
The Correct Answer is B
Choice A rationale
A magnesium sulfate level of 61 mEq/L is high and may cause toxicity, but the most critical level is higher.
Choice B rationale
A magnesium sulfate level of 70 mEq/L is extremely high and most likely to result in toxicity, including respiratory and cardiac complications.
Choice C rationale
A magnesium sulfate level of 29 mEq/L is elevated but not necessarily indicative of toxicity.
Choice D rationale
A magnesium sulfate level of 45 mEq/L is also high but less critical compared to 70 mEq/L.

Correct Answer is ["B","D","F"]
Explanation
Choice A rationale
Documenting the findings in the client's medical record is important but is not the priority action when persistent late decelerations are noted. Immediate interventions are needed to improve fetal oxygenation.
Choice B rationale
Notifying the healthcare provider immediately is crucial as persistent late decelerations indicate fetal distress. The provider can decide on further interventions to ensure the safety of the mother and fetus.
Choice C rationale
Administering a tocolytic medication to stop contractions is not appropriate in this scenario. The priority is to improve fetal oxygenation, not to stop contractions.
Choice D rationale
Repositioning the client to a side-lying position can help improve blood flow to the uterus and placenta, enhancing fetal oxygenation. This is a priority intervention.
Choice E rationale
Administering pain medication to the client is not a priority in this situation. The focus should be on addressing fetal distress and improving oxygenation.
Choice F rationale
Administering oxygen to the client increases the oxygen available to the fetus and is a priority intervention when persistent late decelerations are noted.
