When I see a question with "anorexia" give the patient - ANS ✔✔Fluids
An adolescent patient presents to the emergency room with reports that they were hit in the
eye with a baseball. No visual loss is noted when a Snellen visual acuity is performed, but while
waiting to be assessed by a provider, the patient reports "aching" pain in their eye and sudden
onset of blurry vision. What statement made is greatest concern in the emergency nurse? - ANS
✔✔Comments: "Seeing red" is an indication that blood is present in the anterior chamber.
Activities such as coughing, sneezing, or leaning forward can cause the bleeding to continue or
increase. This causes the anterior chamber to fill with blood and can lead to increased
intraocular pressure due to blood clotting. Increased swelling and lacrimation are anticipated
after an eye injury. Decreased ability to look upward may be a sign on entrapment, however
without vision loss, this would take less priority than the chamber of the eye filling with blood.
