A patient with a pneumothorax has a chest drainage system. The family asks when the chest tube will be removed. Which of the following responses, by the nurse, is best?
a. "The tube is removed when serous drainage has stopped collecting in the system."
b. "The tube is taken out when the patient is able to cough and deep breathe effectively."
c. "When tidaling stops and lung sounds are equal on both sides, the tube can be removed."
d. "When the adventitious lung sounds are resolved, it is usually safe to remove the tube."
ANS: C
Absence of tidaling and bilateral breath sounds are signs that the lung is reinflated and the chest tube can be safely removed. Drainage will generally have stopped at this time also, but it is not the primary determinant for removal. Coughing and deep breathing and clear lung sounds are not signs that the lung is reinflated.
