A nurse is evaluating the fetal status of a client who has preeclampsia and is receiving magnesium sulfate.

Which of the following findings should the nurse report to the provider as a sign of fetal compromise?

Fetal heart rate of 140 beats/min

Fetal movement of 10 times in an hour

Oligohydramnios on ultrasound

Reactive nonstress test

Answer and Explanation

The Correct Answer is C

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

Correct Answer is A

Explanation

Headache that does not respond to analgesics.This is a possible sign of postpartum pre-eclampsia, a rare condition that occurs when a woman has high blood pressure and excess protein in her urine soon after childbirth.Postpartum pre-eclampsia can cause seizures and other serious complications if not treated.

Choice B is wrong because breast engorgement and tenderness are normal symptoms of breastfeeding and do not indicate postpartum pre-eclampsia.

Choice C is wrong because lochia rubra with small clots is a normal discharge of blood and tissue from the uterus after delivery and does not indicate postpartum pre-eclampsia.

Choice D is wrong because perineal pain and swelling are common after vaginal delivery and do not indicate postpartum pre-eclampsia.

Normal ranges for blood pressure are below 120/80 mm Hg and for protein in urine are below 150 mg/day.

A. Administer calcium gluconate as an antidote if toxicity occurs B. Monitor the client’s blood glucose level every 4 hours C. Discontinue the infusion if the client’s respiratory rate is below 16/min D. Increase the infusion rate if the client’s urine output is above 30 mL/hr

Correct Answer is A

Explanation

Administer calcium gluconate as an antidote if toxicity occurs.Magnesium sulfate is a mineral that reduces seizure risks in women with severe preeclampsia.However, it can also cause side effects and toxicity, such as respiratory depression, muscle weakness, and cardiac arrest.Calcium gluconate is an antidote that can reverse the effects of magnesium sulfate and restore normal neuromuscular function.

Choice B is wrong because magnesium sulfate does not affect blood glucose levels.

There is no need to monitor the client’s blood glucose level every 4 hours.

Choice C is wrong because the infusion should be discontinued if the client’s respiratory rate is below 12/min, not 16/min.

A low respiratory rate indicates respiratory depression, which is a sign of magnesium toxicity.

Choice D is wrong because the infusion rate should not be increased if the client’s urine output is above 30 mL/hr.Urine output should be at least 30 mL/hr while administering magnesium sulfate to prevent accumulation of the drug in the body.

Increasing the infusion rate can increase the risk of toxicity.
