What instruction should the nurse give the unit clerk regarding a healthcare provider wanting to prescribe a laxative?

The most appropriate instruction to give the unit clerk is to inform the provider that the nurse will return the call as soon as possible. This response ensures that the healthcare provider is acknowledged, recognizing the importance of their request regarding the prescription of a laxative. It allows the nurse to prioritize patient care by considering the prescription while managing current responsibilities.

By conveying that the nurse will return the call, it maintains the line of communication open and demonstrates professionalism, as it assures the healthcare provider that their request will be addressed in a timely manner. This approach keeps the provider informed and allows for collaborative decision-making regarding patient care.

The other options do not prioritize effective communication and could lead to misunderstandings or delays in necessary patient treatment. For example, simply stating that the nurse is busy or taking a message could result in critical delays in care, especially if the laxative prescription is urgent.
