What is the purpose of having a fenestrated tube in an artificial airway?
To decrease the likelihood of aspiration of stomach contents
To allow a patient to talk
To prevent dislodgement
To prevent trauma to the trachea
The Correct Answer is B
Rationale:
A. To decrease the likelihood of aspiration of stomach contents is not the function of a fenestrated tube; aspiration prevention is managed with cuffed tracheostomy tubes.
B. To allow a patient to talk is correct because the fenestration (small opening) in the tracheostomy tube permits air to flow upward through the vocal cords, enabling speech.
C. To prevent dislodgement is incorrect; tube security is maintained by ties or holders, not fenestration.
D. To prevent trauma to the trachea is not the purpose of fenestration; careful technique and appropriate tube size help prevent trauma.

125 mL/hr × (60 gtt/mL) ÷ (60 min/hr) = 125 gtt/min
Final Answer: D. 125 gtt/min
Correct Answer is C
Explanation
Rationale:
A. Teaching the patient and family what type of drainage is expected and when to report abnormal findings is essential for early detection of infection or complications.
B. Recognizing and preventing hypoxia is critical for patient safety and effective tracheostomy care.
