In a client who underwent a transsphenoidal hypophysectomy, what should the nurse do first when noticing clear drainage from nasal packing?

In the context of a client who has undergone a transsphenoidal hypophysectomy, the priority when noticing clear drainage from nasal packing is to check the drainage for glucose. This is crucial because clear, watery nasal drainage could be an indication of cerebrospinal fluid (CSF) leakage, which is a potential complication following this type of surgery.

CSF has a high glucose content, and testing the drainage for glucose can help to confirm if it is CSF. If glucose is present, it suggests that there may be a breach in the barrier between the cranial cavity and the nasal cavity, which can lead to serious complications, such as infections. This step is critical in ensuring the patient's safety and guiding further interventions.

In comparison, documenting the amount of drainage, obtaining a culture, and notifying the provider, while important, may not address the immediate concern of potential CSF leakage as effectively as confirming the presence of glucose. These actions could follow once the nature of the drainage has been established. Being proactive in identifying a CSF leak can facilitate prompt treatment and mitigate risks associated with this complication.
