In addition to informing the nurse, what should the PCT document when observing significant edema in a patient's legs after treatment?

The appropriate course of action is to document both the observed significant edema in the patient's legs and that the registered nurse (RN) was informed. This documentation is essential for maintaining an accurate and thorough patient record, which is a critical aspect of patient care.

Documenting the observation of edema provides vital information about the patient's condition, which can have implications for their treatment plan. In this case, edema could suggest worsening heart failure, fluid overload, or other complications. By noting both the observation and the communication with the RN, the PCT ensures that there is a clear record of the patient's status and the steps taken in response. This documentation contributes to continuity of care, allowing the healthcare team to make informed decisions based on comprehensive information.

The other choices do not adequately fulfill the requirements of effective patient care documentation. For instance, documenting only the nurse's actions does not capture the initial observation of the edema, which is crucial for understanding the patient's condition. Ignoring the observation because it might be common undermines the individualized assessment that each patient requires, as unusual changes should always be reported and documented. Lastly, documenting only the patient's complaints neglects the objective observation made by the PCT, which can be critical for diagnosis and treatment adjustments.
