The nurse is caring for a pa ent with a history of transient ischemic a acks (TIAs) and moderate
caro d stenosis who has undergone a caro d endarterectomy. Which of the following
postopera ve findings would cause the nurse the most concern?
a) Blood pressure (BP): 128/86 mm Hg
b) Neck pain: 3/10 (0 to 10 pain scale)

d) Difficulty swallowing - Correct Answers Difficulty swallowing
The pa ent's inability to swallow without difficulty would cause the nurse the most concern.
Difficulty in swallowing, hoarseness or other signs of cranial nerve dysfunc on must be
assessed. The nurse focuses on assessment of the following cranial nerves: facial (VII), vagus (X),
spinal accessory (XI), and hypoglossal (XII). Some edema in the neck a9er surgery is expected;
however, extensive edema and hematoma forma on can obstruct the airway. Emergency airway
supplies, including those needed for a tracheostomy, must be available. The pa ent's neck pain
and mild BP eleva on need addressing but would not cause the nurse the most concern.
Hypotension is avoided to prevent cerebral ischemia and thrombosis. Uncontrolled
hypertension may precipitate cerebral hemorrhage, edema, hemorrhage at the surgical incision,
or disrup on of the arterial reconstruc on.
