A client arrives to the emergency department after falling from a ladder. The client has a loss of sensation and flaccid paralysis. Which of the following complications of an acute spinal cord injury does the nurse suspect?

Choice A Reason: Seasonal allergies are not a cause of delirium, but a common condition that affects the respiratory system and causes symptoms such as sneezing, runny nose, itchy eyes, or coughing.

Choice B Reason: History of GERD is not a cause of delirium, but a chronic condition that affects the digestive system and causes symptoms such as heartburn, regurgitation, chest pain, or difficulty swallowing.

Choice C Reason: Benzodiazepines are a cause of delirium, especially in older adults or those with cognitive impairment. Benzodiazepines are a class of drugs that act on the central nervous system and cause sedation, relaxation, and reduced anxiety. However, they can also impair memory, attention, orientation, and judgment, and lead to confusion, agitation, hallucinations, or delusions.

Choice D Reason: Completed antibiotics 10 days ago are not a cause of delirium, but a treatment for bacterial infections. Antibiotics can have side effects such as nausea, diarrhea, rash, or allergic reactions, but they do not cause delirium unless they are toxic or interact with other medications.

Choice A reason: This is the correct answer because the Amsler grid test is performed to diagnose macular degeneration. The Amsler grid is a pattern of straight lines with a dot in the center. The client is asked to look at the dot and report any distortions or missing areas in the grid. This can indicate damage to the macula, which is the central part of the retina that provides sharp vision.

Choice B reason: This is incorrect because the Snellen chart test is not performed to diagnose macular degeneration. The Snellen chart is a chart of letters of different sizes that are read from a distance. The client is asked to read the smallest line they can see clearly. This can indicate visual acuity or sharpness of vision, but not macular degeneration.

Choice C reason: This is incorrect because the intraocular pressure test is not performed to diagnose macular degeneration. The intraocular pressure test measures the pressure inside the eye using a device called a tonometer. The client may feel a puff of air or a gentle touch on their eye. This can indicate glaucoma, which is a condition where increased pressure damages the optic nerve, but not macular degeneration.

Choice D reason: This is incorrect because the refraction test is not performed to diagnose macular degeneration. The refraction test measures how well the eye bends light rays using a device called a phoropter. The client looks through different lenses and reports which ones make their vision clearer. This can indicate refractive errors such as nearsightedness, farsightedness, or astigmatism, but not macular degeneration.
