A nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy. The woman demonstrates an understanding of the nurse's instructions if she states that a positive sign of pregnancy is:
quickening.
a positive pregnancy test.
Braxton Hicks contractions.
fetal movement palpated by the nurse-midwife.
The Correct Answer is D
Choice A reason: Quickening is the first perception of fetal movement by the mother, usually occurring between 16 and 20 weeks of gestation. It is a presumptive sign of pregnancy, as it can be subjective and influenced by other factors such as gas or peristalsis.
Choice B reason: A positive pregnancy test is a probable sign of pregnancy, as it indicates the presence of human chorionic gonadotropin (hCG) in the urine or blood. However, it is not conclusive, as it can be affected by false positives or false negatives, or by other conditions that produce hCG.
Choice C reason: Braxton Hicks contractions are irregular, painless uterine contractions that occur throughout pregnancy. They are a probable sign of pregnancy, as they indicate uterine activity and preparation for labor. However, they are not diagnostic, as they can also occur in non-pregnant women or in response to other stimuli.
Choice D reason: Fetal movement palpated by the nurse-midwife is a positive sign of pregnancy, as it confirms the presence of a living fetus in the uterus. It is an objective and reliable sign that can be detected by a skilled examiner after 20 weeks of gestation.

Correct Answer is D
Explanation
Choice A reason: Magnesium sulfate does not improve patellar reflexes and increase respiratory efficiency. In fact, it may cause hyporeflexia and respiratory depression as adverse effects. These are signs of magnesium toxicity and require immediate intervention.
Choice B reason: Magnesium sulfate does not prevent a boggy uterus and lessen lochial flow. A boggy uterus is a sign of uterine atony, which can lead to postpartum hemorrhage. Lochia is the normal vaginal discharge after childbirth. Magnesium sulfate has no effect on these conditions.
Choice C reason: Magnesium sulfate does not shorten the duration of labor. It may actually prolong labor by relaxing the uterine muscles and inhibiting contractions. Magnesium sulfate is not used to induce or augment labor.
Choice D reason: Magnesium sulfate is used to prevent and treat convulsions in women with preeclampsia and eclampsia. Convulsions are a life-threatening complication of severe hypertension during pregnancy. Magnesium sulfate acts as a central nervous system depressant and anticonvulsant. It reduces the risk of seizures and lowers blood pressure.
Correct Answer is D
Explanation
Choice A reason: She will not be unable to conceive in the future, as ectopic pregnancy does not necessarily affect her fertility. However, she may have a higher risk of having another ectopic pregnancy or infertility if the fallopian tube is damaged or removed.
Choice B reason: A D&C (dilation and curettage) will not be performed to remove the products of conception, as this procedure is used to empty the uterus, not the fallopian tube. The treatment for ectopic pregnancy may include medication, surgery, or expectant management, depending on the location, size, and viability of the pregnancy.
Choice C reason: Bed rest and analgesics are not the recommended treatment for ectopic pregnancy, as they do not address the underlying cause or prevent complications. Ectopic pregnancy is a medical emergency that requires prompt intervention to prevent rupture, bleeding, and shock.
Choice D reason: Hemorrhage is the major concern for ectopic pregnancy, as the pregnancy can rupture the fallopian tube and cause severe bleeding into the abdominal cavity. This can lead to hypovolemic shock, which is a life-threatening condition.
