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.
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 A
Explanation
The correct answer is choice A.Making a loud sound within close range of the newborn will elicit the Moro reflex, which is an involuntary protective motor response against abrupt disruption of body balance or extremely sudden stimulation.The Moro reflex involves three distinct components: spreading out the arms (abduction), pulling the arms in (adduction), and crying (usually).
Choice B is wrong because firmly stroking the soles of the newborn’s feet with a thumb nail will elicit the Babinski reflex, which is a normal response in infants that involves fanning out and curling of the toes.
Choice C is wrong because using the newborn’s hands to raise the baby from a supine position without supporting the head will elicit the traction response, which is a normal response in infants that involves flexion of the elbows and shoulders.
Choice D is wrong because holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface will elicit the stepping reflex, which is a normal response in infants that involves alternating steps with each foot.
Correct Answer is B
Explanation
The correct answer is choice B. The client should avoid sexual intercourse.Sexual intercourse may stimulate uterine contractions and increase the risk of preterm labor.The client should also avoid activities that may cause dehydration, infection, or stress.
Choice A is wrong because documenting urine output hourly is not necessary for a client with preterm labor who is discharged home.Urine output may be affected by hydration status, kidney function, or medication use, but it is not a reliable indicator of preterm labor.
Choice C is wrong because maintaining a darkened, quiet environment is not required for a client with preterm labor who is discharged home.The client may benefit from rest and relaxation, but there is no evidence that light or noise affects preterm labor.
Choice D is wrong because eating small, frequent meals is not specific to a client with preterm labor who is discharged home.Eating small, frequent meals may help with nausea, heartburn, or blood sugar control, but it does not prevent preterm labor.
