A nurse is reviewing the medical history of a client who asks about the use of warfarin.
The nurse should identify which of the following findings as a contraindication for the administration of this medication?
Recent myocardial infarction.
Recent eye surgery.
Thrombophlebitis.
Breast cancer.
The Correct Answer is B
Choice A rationale:
Recent myocardial infarction is not a contraindication for warfarin administration. Warfarin is often prescribed for patients with a history of myocardial infarction to prevent clot formation and reduce the risk of stroke.
Choice B rationale:
Recent eye surgery is a contraindication for the administration of warfarin. Warfarin can increase the risk of bleeding, which is particularly concerning after eye surgery due to the delicate nature of ocular tissues. Using anticoagulants in this scenario can lead to severe complications, including vision loss.
Choice C rationale:
Thrombophlebitis, inflammation of a vein with clot formation, is not a contraindication for warfarin administration. In fact, anticoagulants like warfarin are commonly prescribed to prevent the extension of clots and reduce the risk of complications associated with thrombophlebitis.
Choice D rationale:
Breast cancer is not a direct contraindication for warfarin administration. However, the decision to use anticoagulants in patients with a history of breast cancer should be made carefully, considering individual factors such as the stage of cancer, ongoing treatment, and overall risk of thromboembolic events.

Correct Answer is A
Explanation
Choice A rationale: Evaluating the fetal heart rate tracing is the most critical action in this scenario. The client is at 31 weeks of gestation and reports decreased fetal movement, which could indicate fetal distress. The nurse should first assess the fetal heart rate tracing to ensure the fetus is not in distress. Normal fetal heart rate is between 110 and 160 beats per minute.
Choice B rationale: Obtaining a 24-hour urine collection is important for assessing proteinuria, a sign of preeclampsia, but it is not the most immediate concern. The nurse can initiate this after ensuring the fetus is not in distress.
Choice C rationale: Administering acetaminophen PO (by mouth) can help relieve the client’s headache, but it is not the most immediate concern. The nurse can administer this medication after ensuring the fetus is not in distress and initiating other prescribed treatments.
Choice D rationale: Administering magnesium sulfate IV (intravenously) can prevent seizures in clients with preeclampsia. However, before administering this medication, the nurse should ensure that the fetus is not in distress.
Choice E rationale: Administering betamethasone IM (intramuscularly) can help accelerate fetal lung maturity in case of preterm labor. However, before administering this medication, the nurse should ensure that the fetus is not in distress.
Choice F rationale: Inserting an indwelling urinary catheter can help monitor urine output, which is important for clients receiving magnesium sulfate because oliguria can be a sign of magnesium toxicity. However, before inserting the catheter, the nurse should ensure that the fetus is not in distress.
