The nurse educator asks the student nurse to explain the most common causes of blindness in the United States. Which of the following options will the student nurse select as one of the top causes of blindness?
Head trauma
Cardiovascular disease
Syphilis
Diabetic retinopathy
The Correct Answer is D
Choice A Reason: Head trauma is not one of the top causes of blindness in the United States, but rather a possible cause of it. Head trauma can damage the optic nerve, retina, or brain, leading to vision loss or impairment.
Choice B Reason: Cardiovascular disease is not one of the top causes of blindness in the United States, but rather a risk factor for it. Cardiovascular disease can affect the blood supply and oxygen delivery to the eyes, leading to conditions such as glaucoma, macular degeneration, or retinal vein occlusion.
Choice C Reason: Syphilis is not one of the top causes of blindness in the United States, but rather a rare cause of it. Syphilis is a sexually transmitted infection that can affect the eyes, leading to inflammation, scarring, or detachment of the retina.
Choice D Reason: This is the correct choice. Diabetic retinopathy is one of the top causes of blindness in the United States, affecting about 4.1 million adults. Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina, leading to bleeding, swelling, or leakage of fluid. It can cause blurred vision, floaters, or blindness if left untreated.

Correct Answer is B
Explanation
Choice A Reason: Hemorrhage is not a complication of an acute spinal cord injury, but rather a possible cause of it. Hemorrhage can occur due to trauma or rupture of blood vessels in or around the spinal cord, leading to compression and damage of the nerve tissue.
Choice B Reason: This is the correct choice. Spinal shock is a complication of an acute spinal cord injury that occurs within minutes to hours after the injury. It is characterized by loss of sensation, motor function, reflexes, and autonomic function below the level of injury. It is caused by transient disruption of nerve conduction and synaptic transmission in the spinal cord.
Choice C Reason: Apoptosis is not a complication of an acute spinal cord injury, but rather a cellular process that occurs after it. Apoptosis is programmed cell death that occurs in response to injury or stress. It can lead to further loss of neurons and glial cells in the spinal cord over time.
Choice D Reason: Neurogenic shock is a complication of an acute spinal cord injury that occurs within hours to days after the injury. It is characterized by hypotension, bradycardia, and peripheral vasodilation due to loss of sympathetic tone and unopposed parasympathetic activity. It is caused by disruption of autonomic pathways in the spinal cord.
Correct Answer is ["2600"]
Explanation
The total fluid prescribed is 5,200 mL over 24 hours. We need to calculate how much fluid the client will receive in the first 8 hours.
Step-by-Step Calculation:
Step 1: Determine how much fluid is given in the first 8 hours. The rule is that half of the total fluid is administered in the first 8 hours.
- Total fluid = 5,200 mL.
- Fluid for the first 8 hours = Total fluid ÷ 2.
Write it out:
5,200 ÷ 2 = 2,600.
Result: 2,600 mL.
