A client's chart indicates that they are legally blind. Which of the following is the definition of legally blind?

Full vision loss in at least one eye

The best-corrected vision in the better eye of 20/200 or less

Inability to see clearly from 200 feet away without corrective lenses

Bilateral visual impairment of 20/60 or greater

Answer and Explanation

The Correct Answer is B

Choice A Reason: This is incorrect because full vision loss in one eye does not necessarily mean that the person is legally blind. Legal blindness depends on the visual acuity and visual field of both eyes.

Choice B Reason: This is correct because legal blindness is defined by the World Health Organization (WHO) as having a visual acuity of 20/200 or worse in the better eye with the best possible correction, such as glasses or contact lenses. This means that the person can see at 20 feet what a normal person can see at 200 feet.

Choice C Reason: This is incorrect because inability to see clearly from 200 feet away without corrective lenses may indicate nearsightedness or myopia, but not legal blindness. Nearsightedness can be corrected with lenses or surgery.

Choice D Reason: This is incorrect because bilateral visual impairment of 20/60 or greater does not meet the criteria for legal blindness. Visual impairment is defined by WHO as having a visual acuity of less than 20/60 but better than 20/200 in the better eye with the best possible correction.

Correct Answer is A

Explanation

Choice A Reason: This is correct because first degree burns are superficial burns that affect only the outer layer of the skin, called the epidermis. First degree burns cause redness, pain, and mild swelling, but no blisters or scarring. They usually heal within a week.

Choice B Reason: This is incorrect because second degree burns are partial thickness burns that affect both the epidermis and the underlying layer of the skin, called the dermis. Second degree burns cause blisters, severe pain, and possible infection. They may take several weeks to heal and may leave scars.

Choice C Reason: This is incorrect because third degree burns are full thickness burns that destroy all layers of the skin and may damage the underlying tissues, such as muscles, nerves, or bones. Third degree burns cause charred or white skin, numbness, and shock. They require skin grafting and may cause permanent disability or death.

Choice D Reason: This is incorrect because this burn can be classified according to the depth and extent of the skin damage. The classification of burns helps to determine the appropriate treatment and prognosis for the client.

A. A 40 year old female who drives a motorcycle B. A pregnant female who has high blood pressure C. A 18 year old male who smokes and has a family history of brain cancer D. A 65 year old male client who golfs 3 times a week and drives a golf cart

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.
