A patient has just undergone nasal septoplasty and is now in the post-operative care unit. Which nursing intervention should take priority to prevent complications related to increased intracranial pressure?

A. While a warm compress can help reduce local swelling and discomfort, it does not directly prevent increases in intracranial or intranasal pressure, which could lead to post-operative bleeding or hematoma formation. Comfort measures are important but not the priority for preventing complications. B. Oral hygiene is important for overall health, but resuming tooth brushing immediately post-nasal surgery does not prevent complications from increased intracranial or nasal pressure. Infection prevention is important but not the immediate priority in relation to ICP. C. Blowing the nose, even gently, can significantly increase intranasal and intracranial pressure, which may dislodge surgical packing, cause bleeding, or compromise the septal repair. Post-operative instructions usually include avoiding nose blowing for several days. D. Bending at the waist increases venous pressure in the head and nasal cavity, which can elevate intracranial pressure and increase the risk of post-operative bleeding or hematoma. Teaching the patient to bend at the knees instead of the waist minimizes pressure on the surgical site and is a key preventive intervention after nasal surgery.
