A nurse is caring for a client who underwent emergency retinal detachment repair surgery 6 hours ago. Which assessment finding would require the nurse's immediate intervention?

Sudden severe eye pain with nausea/vomiting indicates increased intraocular pressure, a serious post-op complication requiring immediate intervention. Mild drainage, blurred vision, and dizziness are less urgent.

Understanding the Clinical Priority
The client is in the immediate postoperative period following emergency retinal detachment repair. The nurse's primary focus is monitoring for complications that can threaten vision or indicate a surgical emergency. Among the assessment findings, the ability to distinguish between expected postoperative symptoms and signs of a serious complication is critical.

Analyzing the Correct Answer
The finding that requires immediate intervention is the client's report of sudden onset of severe eye pain with nausea and vomiting. This cluster of symptoms is a classic and alarming presentation for acute angle-closure glaucoma or a significant, rapid rise in intraocular pressure (IOP). In the context of retinal surgery involving silicone oil tamponade, as discussed in the context of complex detachments , a sudden IOP spike is a known and serious complication. The oil can migrate anteriorly, blocking the trabecular meshwork and obstructing aqueous humor outflow. The resulting high pressure can cause intense pain, corneal edema, and a vagal response leading to nausea and vomiting. This constitutes an ocular emergency because sustained elevated IOP can rapidly and permanently damage the optic nerve, leading to irreversible vision loss. The nurse must notify the surgeon immediately for urgent IOP-lowering interventions.

Analyzing the Incorrect Answers
Option 2: Mild drainage and slight redness at the surgical site are common and expected findings 6 hours postoperatively. The inflammatory response to surgical trauma causes some serous or serosanguinous drainage and conjunctival injection. This does not indicate an acute complication requiring immediate intervention, though ongoing monitoring is necessary.

Option 3: A complaint of blurred vision is an anticipated finding after retinal detachment repair. The eye is recovering from significant intraocular manipulation, and the presence of an intraocular gas bubble or silicone oil tamponade will profoundly affect the refractive media, causing severely blurred vision . Postoperative inflammation, corneal edema, and the reattachment process itself also contribute to poor visual acuity in the immediate period. This is not an unexpected emergency.

Option 4: Dizziness upon changing positions is a non-specific symptom that can be related to the lingering effects of anesthesia, preoperative fasting, or vestibular disturbance. While the nurse should implement safety measures to prevent falls, this finding is not directly indicative of a vision-threatening postoperative complication and is a lower priority than symptoms of acute IOP elevation.

Pathophysiology and Clinical Reasoning
The surgical repair of a rhegmatogenous retinal detachment (RRD) aims to close retinal breaks and reattach the neurosensory retina to the retinal pigment epithelium . This often involves pars plana vitrectomy (PPV) with the use of a tamponade agent like gas or silicone oil to hold the retina in place [1,2]. The postoperative period carries risks such as elevated IOP, re-detachment, infection, and proliferative vitreoretinopathy (PVR), a process where cellular membranes contract and re-detach the retina . While PVR is a major cause of late surgical failure, acute IOP elevation is an immediate threat. The nurse's assessment must prioritize the rapid identification of this complication. A sudden, severe pain is the hallmark of a rapid pressure rise, distinguishing it from the mild-to-moderate discomfort expected after surgery. The accompanying nausea and vomiting are a vagal response to the intense pain and high pressure, a key clinical clue that elevates this finding to the highest priority.
