A client's chart indicates that they are legally blind. Which of the following is the definition of legally blind?
A. Full vision loss in at least one eye
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.
B. The best-corrected vision in the better eye of 20/200 or less
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.
C. Inability to see clearly from 200 feet away without corrective lenses
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.
D. Bilateral visual impairment of 20/60 or greater
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.

A client arrives to the clinic after spending the day at the beach. She reports extreme pain and the nurse observes red skin on her face and upper body. There are no blisters present. What degree of burn has the client suffered?
A. First degree
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.
B. Second degree
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.
C. Third degree
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.
D. This burn cannot be classified
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 nurse caring for a client with hepatitis is providing education to the client about portal hypertension. Which of the following will the nurse include in the teaching?
A. "Increased pressure from portal hypertension contributes to the abdominal swelling."
reason: This is the correct answer because portal hypertension means that there is high blood pressure in the portal vein, which carries blood from the digestive organs to the liver. When the liver is damaged by hepatitis, it becomes scarred and obstructs the blood flow, causing increased pressure in the portal vein. This leads to fluid accumulation in the abdomen, called ascites, which causes abdominal swelling.
B. "Portal hypertension is caused by the heart overworking."
reason: This is incorrect because portal hypertension is not caused by the heart overworking but by liver damage. The heart does not pump blood into the portal vein, but into the hepatic artery, which supplies oxygenated blood to the liver.
C. "Portal hypertension develops when the cirrhosis begins to resolve."
reason: This is incorrect because portal hypertension does not develop when cirrhosis begins to resolve, but when it progresses. Cirrhosis is a chronic condition that causes irreversible scarring of the liver tissue, which worsens over time and increases portal hypertension.
D. "Eating high sodium foods and a stressful lifestyle contribute to portal hypertension."
reason: This is incorrect because eating high-sodium foods and a stressful lifestyle do not cause portal hypertension, but they can aggravate it. High-sodium foods can increase fluid retention and worsen ascites, while stress can increase blood pressure and worsen bleeding complications. The nurse should advise the client to limit sodium intake and manage stress levels.

A nurse is caring for a client diagnosed with an inner ear infection. Which of the following manifestations will the nurse expect the client to report?
A. Inability to recognize any words
Reason: This is incorrect because inability to recognize any words may indicate a problem with the auditory cortex, which is the part of the brain that processes sound, not the inner ear. The inner ear consists of the cochlea, which converts sound waves into nerve impulses, and the vestibular system, which helps with balance and orientation.
B. Loss of balance
Reason: This is correct because loss of balance is a common symptom of an inner ear infection. An inner ear infection can cause inflammation and fluid buildup in the vestibular system, which can disrupt the sense of equilibrium and cause vertigo, dizziness, or nausea.
C. Twitching of the cheek
Reason: This is incorrect because twitching of the cheek may indicate a problem with the facial nerve, which controls the muscles of facial expression, not the inner ear. The facial nerve runs close to the inner ear, but it is not part of it.
D. Lack of air sound
Reason: This is incorrect because lack of air sound may indicate a problem with the outer or middle ear, which transmit sound waves to the inner ear, not the inner ear itself. The outer ear consists of the pinna and the ear canal, and the middle ear consists of the eardrum and the ossicles.
