A nurse is caring for a client with chronic otitis media who is scheduled for a mastoidectomy. Which nursing intervention should be the priority in the immediate postoperative period?

Monitoring for facial nerve paralysis is the priority because the facial nerve runs through the mastoid bone and can be damaged during surgery, leading to permanent paralysis if not detected early. Other interventions are important but less critical immediately post-op.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention following a Mastoidectomy, a surgical procedure to remove infected air cells in the mastoid bone, often due to chronic Otitis media. The core theme is postoperative neurological assessment to detect iatrogenic injury to a critical anatomical structure.

Answer Rationale: Key Point! The Facial nerve (Cranial Nerve VII) courses through a narrow bony canal within the mastoid bone (the facial canal). During mastoidectomy, there is a significant risk of injury to this nerve from surgical manipulation, edema, or hematoma. Early detection of facial nerve paralysis (e.g., ipsilateral facial droop, inability to close the eye, loss of nasolabial fold) is critical. Immediate reporting allows for potential interventions (e.g., steroids, surgical exploration) to prevent permanent damage. Therefore, monitoring for signs of facial nerve dysfunction is the undisputed priority in the immediate postoperative period.

Distractor Analysis: Watch out for confusion! Option ②, encouraging coughing and deep breathing, is a standard postoperative intervention to prevent atelectasis and pneumonia. However, it is not the priority specific to mastoidectomy, where the primary threat is neurological, not pulmonary.
Option ③ is incorrect and potentially harmful. The client should be positioned on the unaffected side or with the head of bed elevated. Positioning on the affected side can increase pressure on the surgical site, cause discomfort, and potentially disrupt the graft or packing.
Option ④ represents a dangerous action. The ear packing is placed by the surgeon to provide support, absorb drainage, and protect the middle ear structures. It is typically removed by the physician several days postoperatively. Premature removal by a nurse could lead to graft displacement, infection, and bleeding.

Related Concepts: Post-mastoidectomy care also includes monitoring for signs of meningitis (severe headache, nuchal rigidity, fever) due to the proximity to the meninges, assessing for vertigo (if the labyrinth was involved), and managing pain and nausea. Hearing in the affected ear will be diminished postoperatively due to packing and edema.
Concept Summary

Concept	Key Points
Mastoidectomy Indication	Surgical treatment for chronic otitis media with mastoiditis not responsive to antibiotics.
Primary Anatomical Risk	Facial nerve (CN VII) injury during surgery.
Priority Post-op Assessment	Monitor for facial asymmetry, eye closure, smile symmetry.
Correct Positioning	On unaffected side or semi-Fowler's to reduce edema.
Ear Packing/Canal Care	Leave packing/dressing in place; keep dry; no irrigation.

Anatomy, Physiology & Pharmacology Points • Anatomy: The mastoid process is the bony prominence behind the ear. It contains air cells connected to the middle ear. The facial nerve runs through the facial (Fallopian) canal within the temporal bone, making it vulnerable.
• Physiology: - Facial Nerve (CN VII): Motor function to muscles of facial expression, taste to anterior 2/3 of tongue, lacrimation, salivation.
- Injury leads to Bell's palsy-like symptoms on the ipsilateral side.
• Pharmacology: Postoperative medications may include IV antibiotics (e.g., ceftriaxone), analgesics, and antiemetics. Corticosteroids (e.g., dexamethasone) may be used to reduce inflammation and swelling around the nerve.
Memory Tips • Acronym: For post-mastoidectomy priorities, think "FACE first": Facial nerve, Assess for meningitis, Correct positioning (unaffected side), Ear packing/dry.
• Visual: Picture the surgeon working near the "7-shaped" facial nerve in the bone behind the ear. Damage to nerve #7 affects the face.
High-Frequency NCLEX Topics This topic tests prioritization and surgery-specific complications. The NCLEX loves questions where a general post-op measure (like deep breathing) is a distractor, and the correct answer is the specific assessment or intervention for that particular surgery (like nerve monitoring).
Watch Out for Question Variations! • Instead of asking for the priority intervention, the question could ask: "The nurse assesses the client after mastoidectomy. Which finding requires immediate notification of the surgeon?" (Answer: Inability to close the eye on the operative side).
• The question could focus on patient education: "Which instruction is most important for discharge teaching?" (Answer: Keep the ear dry; avoid blowing nose forcefully to prevent pressure changes).

Nursing Clinical Practice Guide Clinical Scenario: You are assigned to care for Mr. Johnson, a 45-year-old who just returned to the PACU (Post-Anesthesia Care Unit) after a right mastoidectomy for chronic, antibiotic-resistant otitis media. He is groggy but arousable.

Nursing Intervention Strategy: 1. Immediate Assessment (ABCs first, then specific): Ensure airway, breathing, circulation. Then, perform a focused facial nerve assessment. Say "Mr. Johnson, please open your eyes. Now, smile for me. Show me your teeth. Puff out your cheeks." Observe for symmetry. Check his ability to gently close his eyelids completely. Document findings clearly (e.g., "Right facial symmetry intact, able to close right eye completely").
2. Positioning & Comfort: Assist him into a semi-Fowler's position or position him on his left (unaffected) side. Place a small pillow for support. This reduces edema and pressure on the surgical site.
3. Site Care & Monitoring: Check the mastoid dressing behind the right ear for any excessive drainage (mark the outline). A small amount of serosanguineous drainage is expected. Do not remove the inner ear packing. Assess for pain and administer analgesics as ordered.
4. System Monitoring: Monitor for late signs of complications: severe headache/vomiting (meningitis), vertigo/dizziness (labyrinthine irritation), and changes in taste (chorda tympani nerve branch involvement).
5. Patient Education: As he recovers, teach him to avoid getting the ear wet, sneeze/cough with mouth open, avoid blowing nose forcefully, and report fever, severe pain, or increased dizziness.
Nursing Procedure & Medication Flow • Facial Nerve Assessment Procedure: - Timing: Immediately upon PACU arrival, then per protocol (e.g., every 1-2 hours for first 24 hrs).
- Method: Use a systematic approach: "Eyes, Smile, Show Teeth, Puff, Frown." Compare both sides.
- Documentation: "CN VII grossly intact" or note specific deficits: "Right-sided facial droop noted, unable to fully close right eyelid." • Medication Administration: - Analgesics (e.g., acetaminophen with codeine): Administer for pain control to promote rest and healing.
- Antibiotics (IV/oral): Complete the full course as prescribed to eradicate infection.
- Antiemetics (e.g., ondansetron): Given for nausea, which can be caused by anesthesia or inner ear disturbance.
Patient Safety and Precautions: • Key Point! Never irrigate the affected ear or insert anything into the ear canal.
• Instruct the patient to report any clear, watery drainage from the ear or nose, which could indicate cerebrospinal fluid (CSF) leak.
• Protect the eye on the affected side if facial nerve weakness is present. Use artificial tears and an eye patch at night to prevent corneal drying and injury.
A Word from Your Senior Nurse "In ENT nursing, every surgery has its 'signature' complication you must vigilantly watch for. For mastoidectomy, it's the facial nerve. That first post-op assessment isn't just a task—it's your chance to be a neuro-detective. Catching a subtle droop early can make the difference between temporary and permanent paralysis for your patient. When you study, don't just memorize 'assess facial nerve.' Picture yourself at the bedside, asking your patient to smile. Connect the anatomy you learned to the person in front of you. That's how you move from passing a test to being a truly safe and competent nurse."
