Final answer:
The best analysis is maternal toxicity due to the clinical signs such as hyporeflexia and low urine output, which suggest magnesium toxicity. Immediate medical attention is necessary.
Step-by-step explanation:
A client receiving magnesium sulfate intravenously for the treatment of preeclampsia exhibits signs such as a blood pressure of 110/70 mm Hg, a pulse of 98 beats/minute, a respiratory rate of 11 breaths/minute, hyporeflexia, and a urine output of 20 mL/hr.
Given this clinical picture, the best analysis by the nurse would be that maternal toxicity has occurred. Hyporeflexia and a low urine output are indicative of magnesium toxicity and require immediate medical attention.
Magnesium plays an important role in various bodily functions, including blood pressure control, and when administered intravenously, careful monitoring is essential to avoid overdose and toxicity.
