Final answer:
In the context of using mag sulfate and observing reflexes at 0 or +1, it is correct to discontinue magnesium sulfate, as such low reflexes indicate potential magnesium toxicity. Monitoring reflexes closely following the discontinuation is also essential for patient safety.
Step-by-step explanation:
The question refers to the use of mag sulfate (magnesium sulfate) and its effects on reflexes. Magnesium sulfate is commonly used in medicine, particularly in obstetrics, for various treatments including seizure prophylaxis in preeclampsia and preventing premature labor. Reflexes are graded on a scale from 0 to 4+, with 0 being no response and 4+ being hyperactive. A reflex score of 0 or +1 suggests that reflexes are diminished, which can be an indicator of magnesium toxicity. In such a scenario, the correct answer would be: C) Discontinue magnesium sulfate. This is because having very low or absent reflexes can indicate an excessive level of magnesium, which could lead to severe side effects or toxicity. Therefore, it is crucial to stop administering magnesium sulfate if reflexes are significantly reduced and continuously monitor reflexes closely to ensure patient safety.
