The nursing measures for children's pneumonia include ensuring indoor air circulation, maintaining a temperature between 18 to 24 degrees Celsius, and keeping humidity at 60%. Nutritionally rich diets should be provided. For severely ill children who have difficulty eating, parenteral nutrition can be given. Nursing care should include regular changes in position to reduce lung congestion, frequent back patting to help absorb inflammation and expel phlegm, isolation to prevent cross-infection, and attention to the replenishment and correction of water and electrolytes. Electrolyte imbalance should be addressed, and proper fluid supplementation can also help in opening the airways, but it is important to ensure that the infusion rate is not too fast as it may increase the burden on the heart.
