Final Exam: NR569/ NR 569 (NEW 2024/ 2025 Update) Differential Diagnosis in Acute Care Practicum Review| Questions and Verified Answers| 100% Correct – Chamberlain QUESTION Relative Afferent Pupillary Defect (RAPD) - A condition in which pupils respond differently to light stimuli shone in one at a time due to unilateral or asymmetrical disease of the retina or optic nerve. - RAPD is assessed using the swinging penlight technique: A bright light source is directed back and forth at each eye. The eye with the afferent defect will paradoxically dilate when exposed to light after it had previously constricted consensually to the same light applied to the other eye. QUESTION Central Retinal Artery Occlusion Answer: - The sudden blockage of the central retinal artery, resulting in retinal hypoperfusion, rapidly progressive cellular damage, and vision loss. - REFER - This condition is an ophthalmic emergency. Prompt ophthalmology referral is required. QUESTION Acute Angle-Closure Glaucoma Answer: - An ocular emergency that results from a rapid increase in intraocular pressure due to outflow obstruction of aqueous humor. - REFER - This condition is an ophthalmic emergency. Prompt ophthalmology referral is required. QUESTION Central Retinal Vein Occlusion (CRVO) Answer: - An eye condition that affects the retina - the light-sensitive layer of tissue in the back of the eye. It happens when a blood clot blocks the main vein where blood flows out of the retina. It usually only affects one eye. - REFER - This condition is an ophthalmic emergency. Prompt ophthalmology referral is required. QUESTION Hyphema Answer: - Defined as accumulated red blood cells (RBCs) in the anterior chamber of the eye. Blood must be grossly visible, either on direct inspection or slit-lamp examination. Blood accumulates from disruption of the vessels of the iris or ciliary body, usually due to trauma or underlying medical conditions. - REFER - Hyphema is typically caused by trauma. Assess for other eye trauma and consider a CT scan to assess the orbit. Ophthalmology referral is appropriate for ongoing monitoring of ocular pressure. QUESTION Retinal Detachment - An eye problem that happens when the retina (the light-sensitive layer of tissue in the back of the eye) is pulled away from its normal position at the back of your eye. - REFER - This condition is an ophthalmic em
