A nurse is providing teaching about the expected effects of magnesium sulfate to a client who is at 28 weeks of gestation and has preeclampsia. Which of the following responses by the nurse is appropriate?
This medication increases cardiac output
This medication stabilizes the fetal heart rate
The medication improves tissue perfusion
The medication prevents seizures
The Correct Answer is D
A. This medication increases cardiac output: Magnesium sulfate does not typically increase cardiac output. Its primary role in the context of preeclampsia is to prevent seizures and manage hypertension.
B. This medication stabilizes the fetal heart rate: While magnesium sulfate can have a relaxing effect on the uterus, which might indirectly influence fetal heart rate, its primary purpose in preeclampsia is seizure prevention rather than fetal heart rate stabilization.
C. The medication improves tissue perfusion: Magnesium sulfate primarily functions as an anticonvulsant and tocolytic (relaxes the uterus). While its effects on vasodilation can contribute to improved blood flow, the primary indication in preeclampsia is seizure prevention.
D. The medication prevents seizures
Magnesium sulfate is commonly used in the management of preeclampsia to prevent seizures (eclampsia), a serious complication of the condition. It has anticonvulsant properties and is the primary medication for seizure prophylaxis in pregnant individuals with preeclampsia.

Correct Answer is B
Explanation
A. This infection requires that airborne precautions be initiated for the newborn: Cytomegalovirus (CMV) is not typically transmitted through the airborne route. It is primarily spread through direct contact with infected bodily fluids, such as saliva, urine, blood, and genital secretions.
B. Transmission can occur via the saliva and urine of the newborn: CMV can be transmitted through close contact with infected bodily fluids, including saliva and urine. Newborns can contract CMV during delivery or through contact with their mother's infected bodily fluids.
C. Lesions are visible on the mother’s genitalia: Unlike some other viral infections, CMV does not typically present with visible lesions on the genitalia. CMV infection may be asymptomatic or cause mild symptoms in healthy individuals.
D. Mothers will receive prophylactic treatment with acyclovir prior to delivery: Acyclovir is an antiviral medication used to treat herpes simplex virus (HSV) infections, not CMV. There is no standard antiviral prophylactic treatment for CMV in pregnancy.
Correct Answer is D
Explanation
A. Human papillomavirus (HPV): The HPV vaccine is generally not administered during pregnancy. It is recommended for routine vaccination before sexual activity begins to provide protection against certain types of HPV that can lead to cervical cancer and genital warts.
B. Varicella (chickenpox): The varicella vaccine is also typically not administered during pregnancy. If a woman is not immune to varicella and is planning pregnancy, vaccination is recommended before conception.
C. Rubella : The rubella vaccine is crucial for individuals who have not been immunized against rubella during childhood, especially in the context of pregnancy. Rubella (German measles) is a viral infection that can cause serious congenital abnormalities, known as congenital rubella syndrome, if a pregnant woman becomes infected. Administering the rubella vaccine during pregnancy is not appropriate, but vaccination before conception or in the postpartum period is recommended to prevent future rubella infections.
D.The tetanus vaccine is safe to administer during pregnancy, typically given as part of the Tdap (tetanus, diphtheria, and pertussis) vaccine. It is recommended during pregnancy, preferably between 27 and 36 weeks of gestation, to protect the newborn from pertussis.
