If the pilot balloon of a trach or ETT tube is inflated, what can be inferred about the cuff?
The cuff is deflated
The cuff is inflated
The cuff is partially inflated
The cuff is not related to the pilot balloon
The Correct Answer is B
A. If the pilot balloon is inflated, the cuff cannot be deflated.
B. The pilot balloon is connected to the cuff; when the pilot balloon is inflated, it indicates that the cuff inside the trachea or airway is also inflated, providing a seal.
C. Partial inflation cannot be determined solely by the pilot balloon’s inflation status.
D. The pilot balloon is directly related to the cuff and serves as an indicator of its inflation status.

Correct Answer is D
Explanation
Parkland formula:
4 mL × weight (kg) × %TBSA = total fluid in 24 hours
= 4 × 75 × 30 = 9,000 mL total
Half of this is given in the first 8 hours:
9,000 ÷ 2 = 4,500 mL
Fluid rate per hour for first 8 hours:
4,500 mL ÷ 8 hours = 562.5 mL/hr
Therefore, the correct Answer is D.

B. Blistering suggests a partial-thickness (second-degree) burn, often caused by more intense heat or flame exposure.
C. Excessive scarring typically results from deeper burns, such as second- or third-degree burns, not superficial ones.
