A, B, D, E. Administer magnesium sulfate IV is correct. Magnesium sulfate IV is given as a tocolytic medication for preterm labor to relax smooth muscle of the uterus and as a treatment for preeclampsia. The underlying pathophysiology of preeclampsia is vasospasm. The nurse should closely monitor the client for signs of magnesium toxicity, such as loss of patellar reflexes, respiratory depression, cardiac arrhythmias, cardiac arrest, urinary retention, and serum magnesium levels higher than 8 mEq/L.
Provide a dark, quiet environment is correct. A dark, quiet environment helps to decrease CNS stimulation, which minimizes the risk of seizures.
Assess respiratory status every 6 hr is incorrect. The nurse should monitor the client's respiratory status closely because the client is at risk for respiratory depression. A respiratory assessment of every 6 hours is not frequent enough.
Administer pitocin for induction of labor is correct. Delivery is the only cure for preeclampsia, and since the fetus is term induction of labor can be expected.
Ensure that calcium gluconate is readily available is correct. Calcium gluconate is the antidote for magnesium sulfate and should be readily available when administering magnesium sulfate. The nurse should be prepared to administer the medication in response to manifestations of magnesium toxicity, such as depressed respirations, oliguria, sudden drop in BP, loss of deep-tendon reflexes, and fetal distress.
