A nurse is assisting with the care of a school-age child who has respiratory failure due to pneumonia. Which of the following positions should the nurse encourage to allow maximal lung expansion?

Choice A reason: Dry skin is not a sign of respiratory alkalosis. Respiratory alkalosis is a condition where the blood pH is too high due to excessive loss of carbon dioxide through rapid breathing. Dry skin can be caused by dehydration, cold weather, or skin conditions.

Choice B reason: Diarrhea is not a sign of respiratory alkalosis. Diarrhea is a condition where the stool is loose and watery due to increased intestinal motility or infection. Diarrhea can cause metabolic acidosis, which is a condition where the blood pH is too low due to excessive loss of bicarbonate.

Choice C reason: Abdominal pain is not a sign of respiratory alkalosis. Abdominal pain is a symptom that can have many causes, such as gastritis, appendicitis, or irritable bowel syndrome. Abdominal pain can also cause hyperventilation due to anxiety or discomfort, but it is not a direct result of respiratory alkalosis.

Choice D reason: Hyperventilation is a sign of respiratory alkalosis. Hyperventilation is a condition where the breathing rate is faster than normal, causing excess carbon dioxide to be expelled from the lungs. This lowers the partial pressure of carbon dioxide in the blood, which increases the blood pH and causes alkalosis. Hyperventilation can be caused by anxiety, fever, pain, or lung diseases.

Choice A reason: Stripping the client's chest tube every 2 hours is not a recommended action, as it can cause excessive negative pressure, tissue trauma, and pain. The nurse should only strip the chest tube if there is a clot or obstruction in the tubing, and only with the provider's order.

Choice B reason: Looping the tubing of the chest tube on the client's bed is a correct action, as it prevents kinking, tension, or pulling on the chest tube. The nurse should also secure the tubing to the bed sheet with a safety pin.

Choice C reason: Placing the chest tube drainage system above the level of the client's heart is not a correct action, as it can cause the fluid to flow back into the chest cavity and impair lung expansion. The nurse should place the chest tube drainage system below the level of the client's chest.

Choice D reason: Taping the connections on the client's chest tube is a correct action, as it prevents air leaks, disconnections, or accidental removal of the chest tube. The nurse should also check the connections regularly for tightness and patency.
