Correct Answer is B
Explanation
a. The barrier method, which includes male and female condoms, diaphragms, and cervical caps, is effective at preventing pregnancy but may not provide adequate protection against sexually transmitted diseases.
b. Abstaining from sex is the only surefire way to prevent both pregnancy and sexually transmitted diseases.
c. The female condom can provide some protection against pregnancy, but may not provide adequate protection against sexually transmitted diseases.
d. The male condom can provide some protection against pregnancy, but may not provide adequate protection against sexually transmitted diseases.
Correct Answer is B
Explanation
a. This is not the correct choice because the woman has signs of magnesium toxicity, such as low urine output, high blood pressure, and increased DTR. Continuing the infusion could worsen her condition and put her and the fetus at risk.
b. This is the correct choice because the woman needs to be treated for magnesium toxicity, which is a serious complication of preeclampsia. Stopping the infusion will prevent further accumulation of magnesium in her body and allow her to excrete the excess.
c. This is not the correct choice because it will delay the treatment of magnesium toxicity, which is a medical emergency. The woman's vital signs and symptoms are enough to indicate that she has a high level of magnesium and needs immediate intervention.
d. This is not the correct choice because it will not address the underlying cause of magnesium toxicity, which is the infusion. Oxygen may help with some symptoms, such as respiratory depression, but it will not reverse the effects of magnesium on the nervous system and blood vessels.
