Practice Question

A nurse is assessing a client who is receiving magnesium sulfate to treat pre-eclampsia. Which of the following findings should the nurse report to the provider?

Answer Choices:

Correct Answer:

Urinary output 40 mL in 2 hr

Rationale:

🧪Magnesium sulfate is excreted renally; low urine output signals accumulation and risk of magnesium toxicity.

🧪Safe urine output is ≥ 30 mL/hr; 40 mL in 2 hr (20 mL/hr) is below the safety threshold and must be reported immediately.

🧪Toxicity can cause loss of deep tendon reflexes, respiratory depression, and cardiac conduction blocks, making early recognition essential.

🧪Reporting prompts interventions such as holding/reducing the infusion, serum magnesium levels, and antidote (calcium gluconate) availability.

🧪Close monitoring of I&O, reflexes, respiratory rate, and level of consciousness is standard while on magnesium therapy.
