What nursing action is appropriate for a patient who has developed a fever postoperatively?

Encouraging fluid intake is an appropriate nursing action for a patient who has developed a fever postoperatively. Fever can lead to increased metabolic demands and fluid loss through sweat, which can contribute to dehydration. Ensuring that the patient stays well-hydrated can help support their recovery, assist in regulating body temperature, and promote overall healing.

In the context of postoperative care, maintaining adequate hydration is crucial, as patients may have limited fluid intake due to the recent surgery or anesthesia. Proper hydration can also facilitate kidney function and help in the excretion of waste products, supporting the body's efforts to recover from the surgical experience.

While options like documenting and monitoring the fever are important, they do not directly address the physiological implications of fever. Administering aspirin might not be appropriate unless specifically ordered, as it is not always suitable in a postoperative setting due to potential bleeding risks. Calling the physician could be warranted under certain circumstances but is not typically the first step unless the fever is exceptionally high or accompanied by other concerning symptoms. Thus, promoting fluid intake is the most immediate and supportive nursing action in this situation.
