A nurse is nasopharyngeal suctioning an adult patient to remove thick secretions. The nurse will:
use a 14-Fr catheter
use suction pressure between 120 and 160 mm Hg
use an 8-Fr catheter
use the catheter to suction the mouth and nasopharynx
The Correct Answer is A
A. Use a 14-Fr catheter: This is the appropriate size for suctioning an adult to effectively remove thick secretions.
B. Use suction pressure between 120 and 160 mm Hg: This pressure is too high and may cause mucosal damage; 100 to 120 mm Hg is recommended for adults.
C. Use an 8-Fr catheter: This size is too small for effectively suctioning thick secretions in adults.
D. Use the catheter to suction the mouth and nasopharynx: Suctioning the mouth first contaminates the catheter, increasing the risk of infection in the nasopharynx.

Explanation
A. 25 and 50 mm Hg: This pressure is insufficient to effectively clear oral secretions.
B. 80 and 120 mm Hg: Recommended for safe and effective oral suctioning to prevent mucosal trauma while adequately clearing secretions.
C. 120 and 180 mm Hg: Excessive pressure can cause mucosal damage and trauma.
D. 50 and 75 mm Hg: This pressure is too low to be effective for adult oral suctioning.
Correct Answer is D
Explanation
A. Clamp the chest tube and place the patient in high Fowler’s position: Clamping the tube may cause tension pneumothorax and should be done only with a specific prescription.
B. Immediately turn the patient to the side of the insertion site: This action does not address the source of constant bubbling.
C. Document findings: Bubbling in the suction chamber can be normal, but documenting without further assessment may overlook potential system issues.
D. Check for air leaks in the drainage system: Constant bubbling may indicate an air leak, which requires immediate assessment and correction.
