A nurse is assisting with the care of a 15-year-old adolescent who has Streptococcus pneumonia. The nurse is collecting data on the adolescent 24 hr later. How should the nurse interpret the findings? For each finding, click to specify whether the finding is unrelated to the admitting diagnosis, an indication of potential improvement, or an indication of potential worsening condition.

This adolescent has both cystic fibrosis and Streptococcus pneumoniae pneumonia. Interpreting the 24-hour follow-up findings requires distinguishing between changes related to the pneumonia, changes related solely to cystic fibrosis, and trends suggesting improvement or worsening. A WBC count of 17,000/mm³ is a decrease from the admission value of 22,000/mm³, though still mildly elevated; this trend toward normal indicates potential improvement in the infectious process. Hemoptysis of 300 mL is a significant new finding representing a large volume of blood-streaked sputum; this indicates potential worsening, as major hemoptysis is a serious complication of both cystic fibrosis and pneumonia. A respiratory rate of 32 per minute is a decrease from the admission rate of 36 per minute, suggesting the respiratory effort is lessening and pointing toward potential improvement. Steatorrhea — fatty, foul-smelling stools — is a hallmark manifestation of cystic fibrosis resulting from pancreatic enzyme insufficiency; it is unrelated to the pneumonia diagnosis. Oxygen saturation of 95% on 1 L oxygen (down from 2 L) demonstrates that the patient is maintaining the same saturation with less supplemental oxygen, indicating potential improvement in oxygenation. Barrel chest is a chronic structural change associated with air trapping in cystic fibrosis and is unrelated to the pneumonia diagnosis being monitored.
