A nurse is assessing a client who has a chest tube following a thoracotomy. Which of the following findings requires intervention by the nurse?

A. This client's symptom of shortness of breath while ambulating indicates possible worsening heart failure, which requires prompt assessment but is not immediately life-threatening.

B. Vomiting coffee-ground emesis suggests upper gastrointestinal bleeding, which could be

indicative of a serious condition such as a gastrointestinal ulcer or tear and requires immediate assessment to determine the cause and initiate appropriate treatment.

C. While urinary retention in a client with benign prostatic hyperplasia requires attention, it is not as urgent as upper gastrointestinal bleeding.

D. Green drainage from the T-tube in a client who had an open cholecystectomy may indicate bile leakage, which requires assessment and intervention, but upper gastrointestinal bleeding takes precedence due to its potential for rapid deterioration.

A. Allowing the infant to suck on a pacifier during tube feedings can lead to aspiration or choking and is not recommended.

B. Placing enough formula for 12 hours in the feeding container may lead to formula spoilage and contamination, as formula should be prepared fresh for each feeding.

C. Changing the tube feeding setup every 36 hours is not typically necessary unless there are signs of contamination or malfunction. The frequency of changing the setup should be based on institutional policies and manufacturer recommendations.

D. Flushing the tube with water before and after feedings helps ensure proper hydration and prevents tube blockage. A volume of 30 mL is commonly recommended for infants.
