A patient diagnosed with preeclampsia is admitted to the hospital and prescribed magnesium sulfate therapy.
What is the purpose of administering magnesium sulfate to this patient?

To decrease her blood pressure.

To decrease her tidal volume.

To prevent her from becoming dehydrated.

To prevent her from having convulsions.

Answer and Explanation

The Correct Answer is D

The correct answer is choice D: To prevent her from having convulsions. Magnesium sulfate is a mineral that reduces seizure risks in women with preeclampsia, a condition of high blood pressure and protein in the urine during pregnancy. Magnesium sulfate can lower the cerebral perfusion pressure and prevent convulsions. However, magnesium sulfate does not affect the neonatal outcomes and can cause side effects such as respiratory depression.

Choice A is wrong because magnesium sulfate does not decrease blood pressure. It is used along with medications that help reduce blood pressure.

Choice B is wrong because magnesium sulfate does not decrease tidal volume. It can cause respiratory depression if the serum level is too high.

Choice C is wrong because magnesium sulfate does not prevent dehydration. It can cause fluid retention and pulmonary edema if given in excess.

Correct Answer is C

Explanation

This is because urine toxicology studies can detect the presence of cocaine and other drugs in the body of the pregnant woman and her unborn baby.Cocaine use during pregnancy can have serious consequences for both the mother and the baby, such as high blood pressure, premature labor, low birth weight, and developmental problems.

Choice A is wrong because urine estriol levels are used to measure the activity of the placenta and the fetal adrenal glands.They are not related to cocaine use.

Choice B is wrong because serum bilirubin levels are used to assess the liver function and the risk of jaundice in newborns.They are not related to cocaine use.

Choice D is wrong because lecithin-sphingomyelin ratio is used to evaluate the fetal lung maturity and the risk of respiratory distress syndrome.It is not related to cocaine use.

A. Observe the patient for vaginal discharge of bright red blood. B. Assess the patient’s vaginal tone. C. Massage the patient’s perineum. D. Apply petrolatum to the patient’s perineum.

Correct Answer is D

Explanation

The correct answer is choice D. Apply petrolatum to the patient’s perineum.This is because petrolatum can help soothe and protect the perineal area, which may be swollen, bruised, or have stitches after a vaginal delivery.Applying petrolatum can also prevent the pad from sticking to the wound and causing more pain.

Choice A is wrong because observing the patient for vaginal discharge of bright red blood is not a specific action for perineal care.Bright red blood may indicate postpartum hemorrhage, which requires immediate medical attention.

Choice B is wrong because assessing the patient’s vaginal tone is not a priority action for perineal care.Vaginal tone may be reduced after childbirth due to stretching of the pelvic floor muscles, but this can improve with time and exercises.

Choice C is wrong because massaging the patient’s perineum is not recommended for perineal care.Massaging the perineum may cause more trauma and discomfort to the area, especially if there are stitches or hemorrhoids.Massaging the fundus (the top of the uterus) may be done to help it contract and prevent bleeding, but this is different from massaging the perineum.
