A nurse is caring for a client who has eclampsia and is receiving magnesium sulfate and hydralazine.

The client’s blood pressure is 150/90 mmHg, pulse is 88/min, respirations are 18/min, and oxygen saturation is 97%.

The nurse notes that the client’s deep tendon reflexes are absent.

Which of the following actions should the nurse take?

The correct answer is choice A, B, C and E.The nurse should monitor for magnesium toxicity by assessing the deep tendon reflexes, respiratory rate, urine output and serum magnesium level of the client who has severe preeclampsia and is receiving magnesium sulfate IV.Magnesium toxicity can cause life-threatening complications such as hypotension, areflexia (loss of DTRs), respiratory depression, respiratory arrest, oliguria, shortness of breath, chest pains, slurred speech and cardiac arrest.The nurse should also have calcium chloride ready as an antidote for magnesium toxicity.

Choice D is wrong because fetal heart rate is not a direct indicator of magnesium toxicity.However, the nurse should still monitor the fetal heart rate and uterine activity per the Electronic Fetal Monitoring (EFM) Guideline.

Normal ranges for the assessments are:

• Deep tendon reflexes: 1+ to 4+ (normal to hyperactive)

• Respiratory rate: 12 to 20 breaths per minute

• Urine output: at least 30 mL per hour

• Serum magnesium level: 4 to 7 mg/dL (therapeutic range for preeclampsia)

The correct answer is choice A and C. A client with HELLP syndrome is at risk for bleeding, liver damage, and fluid overload or transfusion reaction.Therefore, the nurse should monitor vital signs and urine output to assess for signs of shock, hemorrhage, or renal failure.The nurse should also check for signs of fluid overload or transfusion reaction such as dyspnea, crackles, edema, fever, chills, or rash.

Choice B is wrong because corticosteroids are not indicated for clients with HELLP syndrome unless they have severe thrombocytopenia or need to delay delivery for fetal lung maturity.Corticosteroids may worsen the liver function and increase the risk of infection.

Choice D is wrong because encouraging oral intake of fluids and electrolytes may exacerbate fluid overload and hypertension in clients with HELLP syndrome.Fluid restriction and diuretics may be prescribed to reduce the risk of pulmonary edema and cerebral edema.

Choice E is wrong because maintaining bed rest and a quiet environment may not be sufficient to prevent the progression of HELLP syndrome.The definitive treatment for HELLP syndrome is delivery of the fetus and placenta as soon as possible.Bed rest and a quiet environment may help reduce blood pressure and stress, but they are not the main interventions for this condition.
