A nurse is reinforcing teaching with a client who is undergoing amniotic fluid assessment for the lecithin/sphingomyelin ratio. Which of the following client statements indicates an understanding of the teaching?

- 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.
