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 A
Explanation
Choice A Reason: This is the correct choice because driving a motorcycle is a high-risk activity that can expose the client to head trauma, especially if they do not wear a helmet. Traumatic brain injury (TBI) is a condition where the brain is damaged by an external force, such as a collision, fall, or assault.
Choice B Reason: This is incorrect because having high blood pressure is not a direct risk factor for traumatic brain injury. High blood pressure can increase the risk of stroke, which is a condition where the brain is damaged by an internal cause, such as a blood clot or hemorrhage.
Choice C Reason: This is incorrect because smoking and having a family history of brain cancer are not risk factors for traumatic brain injury. Smoking and genetic factors can increase the risk of developing brain tumors, which are abnormal growths of cells in the brain.
Choice D Reason: This is incorrect because golfing and driving a golf cart are low-risk activities that do not pose a significant threat to the client's head. Golfing and driving a golf cart may cause minor injuries, such as sprains, strains, or bruises, but not traumatic brain injury.
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.
