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
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 the correct answer because airway obstruction is the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Airway obstruction can occur due to edema, inflammation, or inhalation injury of
the upper airway structures. It can compromise oxygenation and ventilation, and lead to respiratory failure or cardiac arrest. The nurse should assess for signs of airway obstruction, such as stridor, hoarseness, dyspnea, or cyanosis, and provide oxygen therapy, humidification, or intubation as needed.
Choice B reason: This is incorrect because fluid imbalance is not the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Fluid imbalance can occur due to fluid loss from damaged skin and capillaries, as well as increased capillary permeability and fluid shifts. It can cause dehydration, hypovolemia, shock, or electrolyte imbalances. The nurse should monitor fluid status, vital signs, urine output, and laboratory values, and provide fluid resuscitation as prescribed, but only after ensuring airway patency.
Choice C reason: This is incorrect because paralytic ileus is not the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Paralytic ileus is a condition where there is decreased or absent bowel motility due to nerve damage or decreased blood flow to
the gastrointestinal tract. It can cause abdominal distension, nausea, vomiting, or constipation. The nurse should assess bowel sounds, abdominal girth, and stool characteristics, and provide nasogastric suction or laxatives as prescribed, but only after ensuring airway patency and fluid balance.
Choice D reason: This is incorrect because infection is not the risk that is the priority for assessment and intervention for a client who has extensive partial and full-thickness burns of
the head, neck, and chest. Infection can occur due to loss of skin barrier, exposure to microorganisms, or impaired immune system. It can cause fever, increased pain, purulent drainage, or sepsis. The nurse should assess for signs of infection, obtain wound cultures, and administer antibiotics as prescribed, but only after ensuring airway patency, fluid balance, and pain control.
Correct Answer is C
Explanation
Choice A reason: This is incorrect because using sign language when communicating with the client is not an appropriate action for the nurse to take. Sign language is a form of communication that uses hand gestures, facial expressions, and body movements. It is not a universal language and requires training and practice. The nurse should not assume that the client knows or prefers sign language unless they have indicated so.
Choice B reason: This is incorrect because speaking loudly and into the client's good ear is not an appropriate action for the nurse to take. Speaking loudly can distort the sound quality and cause discomfort or irritation to the client. Speaking into the client's good ear can also create a sense of imbalance and isolation. The nurse should speak at a normal volume and tone, and face the client directly.
Choice C reason: This is the correct answer because speaking directly to the client in a normal, clear voice is an appropriate action for the nurse to take. Speaking directly to the client can help them see the nurse's mouth movements and facial expressions, which can enhance understanding and communication. Speaking in a normal, clear voice can help convey the message clearly and respectfully.
Choice D reason: This is incorrect because sitting by the client's side and speaking very slowly is not an appropriate action for the nurse to take. Sitting by the client's side can make it difficult for them to see the nurse's face and hear their voice. Speaking very slowly can also make the message unclear and patronizing. The nurse should sit in front of the client and speak at a normal pace.
