A client with preeclampsia is receiving magnesium sulfate to suppress or control seizures. Which nursing intervention should a nurse perform to determine the effectiveness of therapy?
Explanation & Rationale
A. Assess deep tendon reflexes: Magnesium sulfate depresses neuromuscular excitability, which helps prevent seizures. Monitoring deep tendon reflexes, particularly the patellar reflex, allows the nurse to evaluate therapeutic levels and detect early signs of magnesium toxicity, indicating whether the drug is effectively controlling neuromuscular activity. B. Assess for edema: Edema is a common symptom of preeclampsia but does not directly reflect the effectiveness of magnesium sulfate in preventing seizures. While important for overall assessment, it is not a reliable indicator of seizure control. C. Assess the client’s mucous membranes: Monitoring mucous membranes helps evaluate hydration status but does not provide information regarding the effectiveness of magnesium sulfate therapy in seizure prevention. D. Assess the client’s skin turgor: Skin turgor is a measure of fluid status and hydration but does not indicate the therapeutic effect of magnesium sulfate on seizure control in clients with preeclampsia.
