A nurse is reinforcing discharge teaching about car seat safety with the guardian of a newborn. Which of the following information should the nurse include in 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.

A. A glucose level of 60 mg/dL is within the normal range for a full-term newborn. Newborns generally have blood glucose levels between 40 and 60 mg/dL in the first few hours of life, and 60 mg/dL is considered acceptable for a 1-day-old newborn.
B. A WBC count of 10,000/mm³ is within the normal range for a newborn. Newborns can have elevated WBC counts due to the stress of birth, and this finding is not immediately concerning.
C. A platelet count of 225,000/mm³ is normal for a full-term newborn. Platelet counts in newborns generally range from 150,000 to 300,000/mm³, so this result falls within the expected range.
D. A hemoglobin level of 9.5 g/dL is low for a 1-day-old newborn. Normal hemoglobin levels for newborns are typically between 14 and 24 g/dL. Low hemoglobin may indicate anemia, which requires further evaluation and management.
