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

Answer and Explanation

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 D

Explanation

Choice A Reason: This is incorrect because phototherapy is not a recommended therapy for contact dermatitis. Phototherapy involves exposing the skin to artificial light sources that emit specific wavelengths of light that can have anti-inflammatory or immunomodulatory effects. Phototherapy can be used for some skin conditions, such as psoriasis or eczema, but not for contact dermatitis.

Choice B Reason: This is incorrect because antibiotics are not a recommended therapy for contact dermatitis. Antibiotics are drugs that kill or inhibit bacteria that cause infections. Contact dermatitis is not an infection, but an allergic or irritant reaction to a substance that comes in contact with the skin. Antibiotics have no effect on contact dermatitis and may cause adverse effects or resistance.

Choice C Reason: This is incorrect because UV light is not a recommended therapy for contact dermatitis. UV light refers to ultraviolet radiation from sunlight or artificial sources that can damage DNA and cause skin cancer or aging. UV light can also worsen contact dermatitis by increasing inflammation and sensitivity to allergens or irritants.

Choice D Reason: This is correct because avoidance is the best therapy for contact dermatitis. Avoidance means identifying and avoiding the substance that causes the skin reaction. This can prevent further exposure and allow the skin to heal. The nurse can help the client by providing education on how to read labels, use protective clothing or gloves, or substitute safer products.

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.
