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 D
Explanation
The correct answer is choice D. Encourage the client to drink cold, carbonated fluids throughout the day.This helps to relieve the shoulder pain caused by the carbon dioxide gas used to inflate the abdomen during laparoscopy.
The gas irritates the diaphragm, which refers pain to the shoulder.Drinking cold, carbonated fluids can help expel the gas and reduce the pain.
Choice A is wrong because an abdominal binder is not necessary for a laparoscopic procedure.It is more commonly used for abdominal surgeries that involve a large incision.
Choice B is wrong because a rocking chair is not helpful for a client who had a laparoscopic BTL.It is more useful for a client who had a vaginal delivery to promote comfort and uterine involution.
Choice C is wrong because keeping the head of the bed flat for six hours is not indicated for a laparoscopic BTL.It may increase the risk of venous thromboembolism and pulmonary embolism due to prolonged immobility.The client should be encouraged to ambulate as soon as possible after surgery.
Correct Answer is B
Explanation
The correct answer is choice B. The patient’s uterine contraction pattern is enhanced.Prostaglandin E2 gel is used to induce labor by ripening and dilating the cervix and stimulating uterine contractions.The effectiveness of the gel can be measured by the frequency, duration and intensity of the contractions.
A stronger and more regular contraction pattern indicates that the gel is working and labor is progressing.
Choice A is wrong because cervical dilation is not the only indicator of labor induction.Cervical dilation can occur without contractions or with weak and irregular contractions, which means that labor is not established yet.
Choice C is wrong because cervical softening (or effacement) is a prerequisite for cervical dilation, but it does not necessarily mean that labor has started.Cervical softening can occur weeks before labor or even during pregnancy.
Choice D is wrong because uterine softening (or relaxation) is the opposite of what prostaglandin E2 gel is supposed to do.Uterine softening reduces the contractility and tone of the uterus, which can lead to prolonged labor or fetal distress.
