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
Explanation
Choice A rationale:
Evaluating urinary output is important postoperatively, but it does not address the immediate concern of vaginal bleeding.
Choice B rationale:
Replacing the surgical dressing is necessary if it’s saturated, but it does not address the immediate concern of vaginal bleeding.
Choice C rationale:
Applying an ice pack to the incision site can help reduce swelling and pain, but it does not address the immediate concern of vaginal bleeding.
Choice D rationale:
Administering a 500 mL lactated Ringer’s IV bolus can help increase uterine contractility and decrease bleeding. This is the most appropriate action for the nurse to take in this situation.

Explanation
-
Color: Consistent with genetic background
- Interpretation: B) Sign of potential improvement
- Rationale: The newborn’s color being consistent with their genetic background indicates a normal adjustment and is not a sign of deterioration. This suggests improvement from the initial condition of acrocyanosis.
-
Axillary Temperature: 36.3°C (97.4°F)
- Interpretation: B) Sign of potential improvement
- Rationale: The axillary temperature is within the normal range (36.1°C to 37.2°C), which is a positive sign and suggests that the newborn is maintaining normal body temperature.
-
Reflex Irritability: Cry
- Interpretation: B) Sign of potential improvement
- Rationale: A good cry indicates normal reflex irritability and is a positive sign of neurological and overall well-being.
-
Muscle Tone: Flaccid
- Interpretation: C) Sign of potential worsening condition
- Rationale: Flaccid muscle tone is concerning as it might indicate a worsening condition or potential neurological issues. It is less typical for muscle tone to be flaccid after the initial adjustment period.
-
Respiration Effort: Good cry
- Interpretation: B) Sign of potential improvement
- Rationale: A good cry indicates effective respiration and is a positive sign of the newborn’s respiratory status.
-
Heart Rate: 140/min
- Interpretation: B) Sign of potential improvement
- Rationale: The heart rate is within the normal range for newborns (120-160/min), indicating that the cardiovascular system is functioning properly.
