A nurse is providing teaching about the expected effects of magnesium sulfate to a client who is at 28 weeks of gestation and has preeclampsia.
Which of the following responses by the nurse is appropriate?
"This medication increases cardiac output.”.
"This medication prevents seizures.”.
"This medication stabilizes the fetal heart rate.”.
"This medication improves tissue perfusion.”.
The Correct Answer is B
Choice A rationale:
Magnesium sulfate does not increase cardiac output. It is a central nervous system depressant and muscle relaxant.
Choice B rationale:
Magnesium sulfate is given to clients with preeclampsia to prevent seizures, which can be a complication of this condition.
Choice C rationale:
Magnesium sulfate does not directly stabilize the fetal heart rate. Its primary use in preeclampsia is seizure prevention.
Choice D rationale:
While magnesium sulfate can cause vasodilation, which could improve tissue perfusion, its primary use in preeclampsia is to prevent seizures.

Correct Answer is ["D","E","H"]
Explanation
Choice A rationale:
BUN is within the normal range (10 to 20 mg/dL), so it's not an indication of a potential complication.
Choice B rationale:
Potassium is slightly below the normal range (3.5 to 5 mEq/L), indicating potential hypokalemia, which can be a complication.
Choice C rationale:
Hct is at the upper limit of the normal range (33% to 49%), but still within normal, so it's not a complication.
Choice D rationale:
Weight loss of 2 kg in 1 month during pregnancy is concerning and could indicate a complication such as hyperemesis gravidarum.
Choice E rationale:
Heart rate is slightly elevated, which could indicate dehydration, a potential complication.
Choice F rationale:
Sodium is slightly below the normal range (136 to 145 mEq/L), but this alone is not typically a complication of pregnancy.
Choice G rationale:
Hgb is within the normal range (11 to 16 g/dL), so it's not a complication.
Choice H rationale:
Urine-specific gravity is above the normal range (1.005 to 1.030), indicating potential dehydration, a complication.
Correct Answer is B
Explanation
Choice A rationale:
Intense contractions lasting 45 to 60 seconds are normal during labor.
Choice B rationale:
An urge to have a bowel movement during contractions could indicate that the baby’s head is descending into the birth canal, which may require immediate attention.
Choice C rationale:
A sense of excitement and warm, flushed skin are normal emotional and physiological responses during labor.
Choice D rationale:
Progressive sacral discomfort during contractions is a normal part of labor as the baby descends through the birth canal.
