A nurse is reinforcing teaching with a client who is postpartum and receiving warfarin for deep-vein thrombosis. Which of the following instructions should the nurse include?

A. Asymptomatic palpitations are generally not a concern during pregnancy. They can be a common and benign experience due to increased blood volume and changes in heart function.
B. Abdominal cramping at 26 weeks of gestation may indicate preterm labor or other complications and should be reported to the provider. Persistent or severe cramping can be a sign of potential issues requiring medical evaluation.
C. Bleeding gums are common due to increased blood flow and hormonal changes in pregnancy. This symptom is usually not serious but should still be monitored.
D. White vaginal discharge is normal during pregnancy and often increases as pregnancy progresses. It is usually not a sign of a problem unless accompanied by other symptoms.
Here’s a detailed answer for each of the s using the specified format:

- Rationale for A: Aspirin is an antiplatelet agent and can increase the risk of bleeding, especially when combined with warfarin, an anticoagulant. Therefore, taking aspirin for leg discomfort is not recommended as it can exacerbate bleeding risks.
- Rationale for B: Oral contraceptives can interfere with the effectiveness of warfarin and increase the risk of thrombotic events. Women taking warfarin, especially in the postpartum period, should avoid oral contraceptives due to the potential for increased blood clotting.
- Rationale for C: The duration of warfarin therapy for deep-vein thrombosis is typically longer than 2 weeks. It is determined by the physician based on the extent of the clot and the patient's response to the medication.
- Rationale for D: Using a disposable razor can help minimize the risk of cuts and subsequent bleeding, which is a concern when taking anticoagulants like warfarin. It is a safer alternative to other shaving methods that may cause skin abrasions.
