Which of the following represents the burn percentage for the anterior and posterior of both arms using the Rule of Nines?
9%
12%
36%
18%
The Correct Answer is D
A. 9% represents the total surface area of one arm (anterior and posterior combined), not both arms.
B. 12% is not a correct calculation based on the Rule of Nines.
C. 36% represents a much larger area, such as the entire trunk (anterior and posterior), not just the arms.
D. According to the Rule of Nines, each arm accounts for 9% of total body surface area (4.5% anterior + 4.5% posterior). Therefore, both arms (anterior and posterior) equal 18% total

Correct Answer is B
Explanation
A. CPAP is typically used for simpler obstructive sleep apnea, while BiPAP is often used for more complex cases.
B. BiPAP delivers two different pressure levels: a higher pressure during inhalation (IPAP) and a lower pressure during exhalation (EPAP), which helps patients breathe more easily.
C. CPAP delivers a continuous, single pressure level throughout the breathing cycle, not two different pressures.
D. This describes CPAP rather than BiPAP.
Correct Answer is C
Explanation
A. Infection prevention is managed through sterile technique and proper tracheostomy care, not by using a one-way valve cap.
B. A one-way valve cap does not deliver oxygen; in fact, it requires that the patient be able to breathe through their upper airway.
C. The purpose of a one-way valve cap (such as a Passy-Muir valve) is to facilitate speech by allowing air to enter through the tracheostomy but forcing exhaled air through the vocal cords and upper airway, enabling phonation and improved communication.
D. Suctioning is performed through the tracheostomy tube, but the one-way valve cap is not designed to assist in that process.
