A nurse is caring for a client with pre-eclampsia who is receiving magnesium sulfate.
What is the rationale for administering this medication?
To prevent seizures
To lower blood pressure
To increase urine output
To promote fetal lung maturity
The Correct Answer is A
To prevent seizures. Magnesium sulfate is given to reduce central nervous system irritability and prevent seizures in clients with preeclampsia. Preeclampsia is a hypertensive disorder that occurs after 20 weeks of gestation and is characterized by elevated blood pressure, proteinuria, edema, headache, epigastric pain, and vision changes.
Choice B is wrong because magnesium sulfate does not lower blood pressure. Some antihypertensive drugs might be given to manage blood pressure in clients with preeclampsia.
Choice C is wrong because magnesium sulfate does not increase urine output. In fact, it can cause urinary retention and oliguria as adverse effects.
Choice D is wrong because magnesium sulfate does not promote fetal lung maturity.
It is given to prevent maternal complications, not fetal ones. Corticosteroids might be given to promote fetal lung maturity if delivery is anticipated before 34 weeks of gestation.

Correct Answer is B
Explanation
Decreased fibrinogen level.This indicates that the client has a risk of disseminated intravascular coagulation (DIC), which is a condition where the blood clots abnormally and causes bleeding in various organs.Fibrinogen is a protein that is essential for blood clotting, and a low level means that the clotting factors are being consumed faster than they can be produced.
Choice A is wrong because elevated platelet count is not a sign of DIC, but rather of normal pregnancy or other conditions that cause thrombocytosis.Platelets are blood cells that help form clots, and a high count means that there is an increased production or decreased destruction of platelets.
Choice C is wrong because increased prothrombin time (PT) is not a specific sign of DIC, but rather of any condition that affects the extrinsic pathway of coagulation.PT measures how long it takes for the blood to clot by adding tissue factor, which activates factor VII.A prolonged PT means that there is a deficiency or dysfunction of factor VII or other factors in the common pathway (X, V, II, I).
Choice D is wrong because reduced partial thromboplastin time (PTT) is not a sign of DIC, but rather of hypercoagulable states or antiphospholipid syndrome.PTT measures how long it takes for the blood to clot by adding phospholipids and an activator, which activate factor XII.A shortened PTT means that there is an increased activity or presence of factor XII or other factors in the intrinsic or common pathway.
Correct Answer is ["A","B"]
Explanation
The correct answer is choice A and B.Sudden weight gain and decreased fetal movement are signs of pre-eclampsia, a condition that develops in pregnant women and is marked by high blood pressure and presence of proteins in urine.Pre-eclampsia can affect the blood supply to the placenta and the growth of the baby.
Choice C is wrong because vaginal bleeding is not a symptom of pre-eclampsia, but it may indicate other problems such as placental abruption or miscarriage.
Choice D is wrong because nausea and vomiting are not specific symptoms of pre-eclampsia, but they may occur in some cases.However, excessive vomiting and nausea may be a sign of severe pre-eclampsia.
