A nurse is performing a Weber test on a client who reports difficulty hearing in his left ear. The client informs the nurse that he can hear the tone louder in his left ear. Which of the following does this result indicate?

Choice A Reason: Measuring the abdominal girth is not related to asterixis, which is a tremor of the hand when the wrist is extended. It may indicate ascites, which is a complication of cirrhosis, but not asterixis.

Choice B Reason: This is the correct choice. Asterixis is a flapping tremor of the hand when the wrist is extended, sometimes said to resemble a bird flapping its wings. It is caused by abnormal function of the diencephalic motor centers that regulate the muscles involved in maintaining posture. It is a sign of hepatic encephalopathy, which is a neuropsychiatric disorder that occurs in patients with liver disease.

Choice C Reason: Having the client flex and extend their foot is not related to asterixis, which affects the hand and wrist. It may test for ankle clonus, which is a rhythmic contraction of the calf muscles when the foot is dorsiflexed. It indicates an upper motor neuron lesion, but not hepatic encephalopathy.

Choice D Reason: Asking the client to walk heel to toe is not related to asterixis, which affects the hand and wrist. It may test for balance and coordination, which can be impaired in patients with hepatic encephalopathy, but it is not a specific sign of asterixis.

Choice A Reason: This is incorrect because submerging the client in a cold bath can cause hypothermia, shock, or infection. Cold water can lower the body temperature and blood pressure, which can impair circulation and organ function. Cold water can also introduce bacteria or contaminants into the open wounds. The nurse should use cool water or saline to gently irrigate the burned areas and then cover them with sterile dressings.

Choice B Reason: This is correct because administering oxygen can help the client breathe better and prevent hypoxia. Burns to the face, neck, or chest can cause swelling or damage to the airway, which can impair gas exchange and oxygen delivery. Oxygen can also reduce the risk of carbon monoxide poisoning, which can occur from inhaling smoke or fumes.

Choice C Reason: This is incorrect because restricting fluids can worsen dehydration and shock. Burns can cause significant fluid and electrolyte loss through evaporation and leakage from damaged capillaries. This can lead to hypovolemia, which is low blood volume, and hypotension, which is low blood pressure. The nurse should monitor the client's vital signs, urine output, and weight, and administer intravenous fluids as ordered.

Choice D Reason: This is incorrect because providing a meal high in fiber can cause abdominal discomfort or diarrhea. Burns can cause paralytic ileus, which is a temporary loss of bowel function due to nerve damage or inflammation. This can impair digestion and absorption of food and cause nausea, vomiting, or constipation. The nurse should assess the client's bowel sounds and provide enteral or parenteral nutrition as ordered.

Choice E Reason: This is correct because assessing airway is a priority nursing action for a client with burns. As mentioned above, burns to the face, neck, or chest can compromise the airway and cause respiratory distress or failure. The nurse should assess the client's level of consciousness, breathing rate and pattern, oxygen saturation, and signs of inhalation injury, such as sooty sputum, singed nasal hairs, or hoarseness. The nurse should also be prepared to assist with intubation or tracheostomy if needed.

Choice F Reason: This is correct because applying ice to burned areas can help reduce pain and swelling. Ice can constrict blood vessels and numb nerve endings, which can decrease inflammation and sensation. However, ice should be applied for no more than 15 minutes at a time and wrapped in a cloth or towel to prevent frostbite or tissue damage. Ice should not be applied to large or deep burns.
