Expressed breast milk can be stored at room temperature for
**Core Concept**
Expressed breast milk (EBM) storage is crucial for feeding mothers who are not immediately feeding their infant directly. The storage guidelines are based on the risk of bacterial growth and the stability of immunoglobulins and other nutrients in EBM.
**Why the Correct Answer is Right**
The correct answer is **6 hours**. This is because EBM can be safely stored at room temperature (about 25°C or 77°F) for up to 6 hours. This is due to the natural acidity of breast milk, which acts as a barrier to bacterial growth. Additionally, the fatty acids in breast milk help to inhibit the growth of microorganisms. However, it's essential to note that after 6 hours, the risk of bacterial contamination increases, and refrigeration is recommended.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is likely incorrect because there is no standard duration for storing EBM at room temperature beyond 6 hours. Storing EBM for more than 6 hours at room temperature increases the risk of bacterial contamination.
* **Option B:** This option is incorrect because refrigeration is recommended for stored EBM, not just for longer-term storage. Refrigeration slows down bacterial growth and helps maintain the quality of EBM.
* **Option C:** This option is incorrect because while freezing is a valid method for long-term storage of EBM, it's not the correct answer for storage at room temperature.
**Clinical Pearl / High-Yield Fact**
When storing EBM, it's essential to label the containers with the date and time of expression, and to use a clean and airtight container to prevent contamination. This helps ensure the quality and safety of the stored EBM.
**Correct Answer:** C. 6 hours
