A nurse is reviewing the results of laboratory screenings for a 9-month-old infant.
Which of the following results should the nurse report to the provider?

Have the client wear a surgical mask while being transported outside the room.

• A. Initiate contact precautions for the client upon admission. This is incorrect because contact precautions are not sufficient to prevent the spread of TB, which is an airborne disease that can travel through small droplets in the air.
• B. Restrict visitors from entering the client's room during hospitalization. This is incorrect because visitors can enter the client's room as long as they wear appropriate personal protective equipment (PPE) such as an N95 respirator, gown, gloves, and eye protection.
• C. Wear a surgical mask while providing care for the client. This is incorrect because a surgical mask does not filter out small airborne particles that carry TB bacteria. The nurse should wear an N95 respirator or higher level of respiratory protection when caring for a client who has active TB.
• D. Have the client wear a surgical mask while being transported outside the room. This is correct because a surgical mask can reduce the amount of droplets that are expelled by the client when coughing or sneezing, thus minimizing the risk of infecting others in common areas or hallways.

Choice A rationale:

Keeping a can of concentrated formula in the refrigerator for 3 days after opening it is not safe. Once a can of formula is opened, it should be used within 24 hours and stored in the refrigerator. After 24 hours, any leftover formula should be discarded to prevent the risk of bacterial contamination.

Choice B rationale:

Diluting ready-to-feed formula with water is incorrect. Ready-to-feed formula is already prepared and does not need to be diluted further. Adding water to ready-to-feed formula can dilute its nutritional content and may not provide the necessary nutrients for the baby.

Choice C rationale:

Boiling tap water for 2 minutes and cooling it before mixing it with powdered formula is the correct method for safe formula preparation. Boiling the water kills harmful bacteria and ensures the formula is safe for the baby to consume. It is essential to cool the boiled water before mixing it with powdered formula to reach an appropriate feeding temperature.

Choice D rationale:

Ensuring that all bottles contain BPA (bisphenol A) is not a relevant consideration for formula preparation. BPA is a chemical that was previously used in some plastics, including baby bottles, but has been banned in baby bottles and sippy cups in several countries due to its potential health risks. Most modern baby bottles are BPA-free, and this statement does not address the safe handling and preparation of formula for the baby.
