A woman with severe preeclampsia has been receiving magnesium sulfate by intravenous infusion for 8 hours.
 
  The nurse assesses the woman and documents the following findings: temperature of 37.1 C, pulse rate of 96 beats/min, respiratory rate of 24 breaths/min, blood pressure (BP) of 155/112 mm Hg, 3+ deep tendon reflexes, and no ankle clonus. The nurse calls the physician, anticipating an order for:
  a. Hydralazine. c. Diazepam.
  b. Magnesium sulfate bolus. d. Calcium gluconate.

Question 2

The labor of a pregnant woman with preeclampsia is going to be induced.
 
  Before initiating the Pitocin infusion, the nurse reviews the woman's latest laboratory test findings, which reveal a platelet count of 90,000, an elevated aspartate transaminase (AST) level, and a falling hematocrit. The nurse notifies the physician because the laboratory results are indicative of:
  a. Eclampsia.
  b. Disseminated intravascular coagulation (DIC).
  c. HELLP syndrome.
  d. Idiopathic thrombocytopenia.

Answer to Question 1

ANS: A
Hydralazine is an antihypertensive commonly used to treat hypertension in severe preeclampsia. Typically it is administered for a systolic BP greater than 160 mm Hg or a diastolic BP greater than 110 mm Hg. An additional bolus of magnesium sulfate may be ordered for increasing signs of central nervous system irritability related to severe preeclampsia (e.g., clonus) or if eclampsia develops. Diazepam sometimes is used to stop or shorten eclamptic seizures. Calcium gluconate is used as the antidote for magnesium sulfate toxicity. The client is not currently displaying any signs or symptoms of magnesium toxicity.

Answer to Question 2

ANS: C
HELLP syndrome is a laboratory diagnosis for a variant of severe preeclampsia that involves hepatic dysfunction characterized by hemolysis (H), elevated liver enzymes (EL), and low platelets (LP). Eclampsia is determined by the presence of seizures. DIC is a potential complication associated with HELLP syndrome. Idiopathic thrombocytopenia is the presence of low platelets of unknown cause and is not associated with preeclampsia.
