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.
