Multiple Choice
1. A child sustains an ocular injury in which a shard of glass from a bottle penetrated the eye wall. The emergency department provider notes that the shard has remained in the eye. Which term best describes this type of injury?
a. Intraocular foreign body b Penetrating eye injury c. Perforating eye injury d. Ruptured globe injury
ANS: A a. Because the posterior segment is not involved, the prognosis is good. b. Blindness is likely with this type of eye injury. c. Massive hemorrhage and loss of intraocular contents is likely.
When a portion of the insulting object enters and remains in the eye, the injury is correctly referred to as an intraocular foreign body. A penetrating injury occurs when something penetrates through the eye wall without an exit wound. A perforating injury occurs when the object has both an entry and an exit wound. A ruptured globe injury occurs when blunt force causes the eye wall to rupture.
2. A patient experiences a penetrating injury to one eye caused by scissors. The provider notes a single laceration away from the iris that involves the anterior but not the posterior segment. What is the prognosis for this injury?
NURSINGTB.COM d. Retinal detachment is almost certain to occur.
ANS: A a. 2 mm polycarbonate safety glasses b. Eyewash stations c. Glasses with UVB protection d. Polycarbonate goggles
Mechanical energy imparted from sharp objects generally results in lacerations, with disruption that is more localized. The prognosis is better if the posterior segment is not involved. The other complications are more common with globe ruptures.
3. Which protective precaution is especially important in a metal fabrication workshop?
ANS: D
Polycarbonate goggles, which have better side protection, will protect from foreign bodies that can reach around other lenses and should be used in very high-risk activities, such as hammering metal on metal or grinding. 2 mm polycarbonate safety glasses are a minimum safety precaution. Glasses with UVB protection are used in occupations where sunlight exposure is high. Eyewash stations are necessary where splash injuries or chemical exposures are possible.
