A nurse is performing a focused assessment for vision on a client suspected of having vision loss. Which cranial nerve is the nurse assessing when determining if there are visual field or visual acuity deficits?

Choice A Reason: This is a correct choice. Trying to avoid scratching is an advice that the nurse will provide to the client, as it prevents further damage and infection of the skin. Scratching can break the skin barrier and introduce bacteria or fungi into the wound, leading to inflammation and complications.

Choice B Reason: This is a correct choice. Applying a moist cool compress is an advice that the nurse will provide to the client, as it soothes and relieves itching and swelling. A moist cool compress can reduce inflammation and histamine release, which are responsible for allergic symptoms.

Choice C Reason: This is an incorrect choice. Using alcohol to cleanse the area is not an advice that the nurse will provide to the client, as it irritates and dries out the skin. Alcohol can strip away the natural oils and moisture from the skin, making it more prone to cracking and itching.

Choice D Reason: This is an incorrect choice. Using a wooden stick to scratch lesions is not an advice that the nurse will provide to the client, as it causes more harm than good. A wooden stick can injure or infect the skin, as well as spread the allergen or irritant to other areas.

Choice E Reason: This is a correct choice. Avoiding hot air is an advice that the nurse will provide to the client, as it aggravates itching and inflammation. Hot air can increase blood flow and histamine release, which are responsible for allergic symptoms. The client should also avoid hot water or showers, as they can have the same effect.

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.
