A patient with preeclampsia is being treated with bed rest and intravenous magnesium sulfate. The drug classification of this medication is a

Correct Answer: C

Rationale: The correct answer is C: anticonvulsant. Magnesium sulfate is commonly used in preeclampsia to prevent seizures/eclampsia. It works by reducing neuromuscular transmission and excitability, making it an effective anticonvulsant. Diuretics (A) help remove excess fluid, tocolytics (B) inhibit uterine contractions, and antihypertensives (D) lower blood pressure, but they do not address the primary purpose of using magnesium sulfate in preeclampsia, which is to prevent seizures.

Correct Answer: D

Rationale: The correct answer is D: marginal. In placenta previa, when the placental edge just reaches the internal os, it is classified as marginal. This indicates that the placenta is close to, but not covering, the cervical os. Total previa covers the entire os, partial covers part of it, and low-lying indicates the placental edge is near the os but not reaching it. The key is to understand the specific location of the placental edge in relation to the internal os for each classification.

Correct Answer: B

Rationale: The correct answer is B because Rh incompatibility occurs when an Rh-negative mother carries an Rh-positive fetus. During pregnancy or birth, some fetal Rh-positive blood may enter the mother's bloodstream, leading to the production of Rh antibodies. These antibodies can then cause complications in future pregnancies if the fetus is Rh-positive again. Choices A, C, and D are incorrect because Rh incompatibility specifically involves the Rh factor of the fetus, not the mother's own Rh status, the father's Rh status, or both being Rh-negative.

Correct Answer: A

Rationale: The correct answer is A: Determining cervical dilation and effacement. This assessment is contraindicated for a patient with suspected placenta previa because it can lead to further disruption of the placenta and potentially cause severe bleeding. Monitoring FHR and vital signs (B) is important for assessing fetal well-being and maternal status. Observing vaginal bleeding or amniotic fluid leakage (C) is crucial in identifying complications. Determining the frequency, duration, and intensity of contractions (D) is essential for monitoring labor progression but is not appropriate for a patient with suspected placenta previa due to the risk of placental disruption.

Correct Answer: A

Rationale: The correct answer is A: Hemorrhage is the primary concern. In an ectopic pregnancy, the fertilized egg implants outside the uterus, typically in the fallopian tube, which can lead to life-threatening internal bleeding. Nursing care focuses on monitoring for signs of hemorrhage, such as abdominal pain, vaginal bleeding, and signs of shock. Prompt intervention is crucial to prevent serious complications. Explanation of why the other choices are incorrect: B: She will be unable to conceive in the future - This statement is not true as having an ectopic pregnancy does not necessarily impact future fertility. C: Bed rest and analgesics are the recommended treatment - Bed rest and analgesics are not the primary treatments for ectopic pregnancy, as surgical intervention is often necessary. D: A D&C will be performed to remove the products of conception - A D&C is not typically performed for ectopic pregnancy management, as it involves the removal of tissue from inside the uterus, not the fallopian
