MODULE 19 / 20

Eye Trauma & Chemical Injury

Provide safe initial recognition and escalation for chemical, blunt and penetrating injury.

Answer all 10 questions, then submit to see your score and explanations. This is a self-study exercise; results are not saved.

Question 01. What is the first priority for an isolated chemical splash with no suspected penetration? A. Begin immediate copious irrigation while arranging careB. Wait for a complete written historyC. Search for a preferred fluid for an hourD. Apply a pressure patch

Question 02. If appropriate sterile irrigation fluid is not immediately available, what may be used for an isolated splash? A. A reactive neutralising acidB. Concentrated antisepticC. Oil-based paint thinnerD. Clean water

Question 03. Why avoid neutralising an acid with an alkali in the eye? A. It is always less effective than doing nothingB. The reaction can cause additional injuryC. It makes the lens disappearD. It prevents pH assessment permanently

Question 04. A high-velocity metal injury with a tiny surface mark requires consideration of what? A. Only superficial irritationB. PresbyopiaC. Seasonal allergyD. An intraocular foreign body

Question 05. What should protect a suspected open globe during urgent transfer? A. A rigid shield without pressureB. A tight pressure patchC. A compressive bandageD. Repeated digital palpation

Question 06. Which examination should be avoided in suspected globe rupture? A. Taking a noncontact historyB. TonometryC. Recording mechanismD. Calling ophthalmology

Question 07. What should be done with an object embedded in the eye? A. Pull it out immediately without equipmentB. Leave it in place for emergency specialist managementC. Push it farther inwardD. Rotate it to test movement

Question 08. Blood in the anterior chamber after trauma is called what? A. HypopyonB. PapilloedemaC. HyphaemaD. Chalazion

Question 09. Why avoid MRI when a metallic intraocular foreign body is possible? A. MRI always measures eye pressure incorrectlyB. MRI cannot image any head structureC. Magnetic forces can move susceptible metalD. Metal always dissolves during scanning

Question 10. How should combined chemical exposure and suspected penetrating injury be handled? A. Apply forceful irrigation devices routinelyB. Remove protruding tissue firstC. Delay all help until pain stopsD. Obtain immediate expert guidance and avoid pressure-producing manipulation
