Question 2 of 5
A nurse is performing the routine daily cleaning of a tracheostomy. During the procedure, the client coughs and displaces the tracheostomy tube. This negative outcome could have been avoided by
Correct Answer: C
Rationale: fastening clean tracheostomy ties before removing old ties. Fastening clean tracheostomy ties before removing old ones will ensure that the tracheostomy is secured during the entire cleaning procedure. The obturator is useful to keep the airway open only after the tracheostomy outer tube is coughed out. A second nurse is not needed. Changing the position may not prevent a dislodged tracheostomy.
Question 3 of 5
During the rehabilitative phase, the client's burns become infected with pseudomonas. The topical dressing most likely to be ordered for the client is:
Correct Answer: C
Rationale: Mafenide acetate (Sulfamylon) is particularly effective against Pseudomonas infections due to its broad-spectrum antibacterial activity and ability to penetrate eschar. Silver sulfadiazine is less effective against Pseudomonas, and povidone-iodine and silver nitrate are not the primary choices for Pseudomonas infections. Answers A, B, and D are incorrect because they are less effective for this specific infection.
