A nurse is administering magnesium sulfate IV to a client who has severe preeclampsia.
Which of the following assessments should the nurse perform to monitor for magnesium toxicity? Select all that apply.
Deep tendon reflexes
Respiratory rate
Urine output
Fetal heart rate
Serum magnesium level
Correct Answer : A,B,C,E
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)

Correct Answer is A
Explanation
The client has no seizures.Magnesium sulfate therapy is used to prevent seizures in women with preeclampsia and eclampsia.Seizures are a life-threatening complication of eclampsia and indicate a failure of therapy.
Choice B is wrong because diuresis is not a goal of magnesium sulfate therapy.Diuresis may indicate fluid overload or renal impairment, which are complications of preeclampsia and eclampsia.
Choice C is wrong because improved fetal movement is not a direct outcome of magnesium sulfate therapy.Fetal movement may be affected by many factors, such as gestational age, maternal position, and fetal well-being.
Choice D is wrong because increased platelet count is not a result of magnesium sulfate therapy.Platelet count may be decreased in preeclampsia and eclampsia due to disseminated intravascular coagulation, which is a serious complication that requires prompt treatment.
Normal ranges for blood pressure are less than 140/90 mm Hg, for proteinuria are less than 300 mg/24 hours, for platelet count are 150,000 to 400,000/mm3, and for serum magnesium are 1.5 to 2.5 mEq/L.
Correct Answer is C
Explanation
Oligohydramnios on ultrasound.Oligohydramnios is a condition where the amniotic fluid volume is less than expected for gestational age.It can be a sign of fetal compromise due to various causes, such as renal abnormalities, placental insufficiency, premature rupture of membranes, or chromosomal anomalies.Oligohydramnios can lead to complications such as fetal deformities, preterm birth, infection, or stillbirth.
Choice A is wrong because a fetal heart rate of 140 beats/min is within the normal range for most of pregnancy.
Choice B is wrong because fetal movement of 10 times in an hour is also within the normal range and indicates fetal well-being.
Choice D is wrong because a reactive nonstress test is a reassuring sign that the fetus is not hypoxic or stressed.
Normal ranges:
• Amniotic fluid index (AFI): 5-25 cm
• Fetal heart rate: 110-160 beats/min
• Fetal movement: at least 10 movements in 2 hours
• Nonstress test: at least two accelerations of fetal heart rate of 15 beats/min for 15 seconds or more in 20 minutes
