What is the most appropriate method to calculate the total body surface area (TBSA) burned in an adult patient?
Rule of Nines
Body Mass Index (BMI)
Patient's palm size
Parkland Burn Chart
The Correct Answer is A
A. The Rule of Nines is the most commonly used and appropriate method to quickly estimate the TBSA burned in adult patients. It divides the body into sections, each representing approximately 9% (or a multiple thereof) of the total body surface area.
B. BMI is used to assess body fat and weight status, not burn area.
C. The patient’s palm size is roughly 1% of TBSA and is more commonly used for estimating small, scattered burns, not for calculating large surface areas.
D. There is no such tool as the "Parkland Burn Chart"; the Parkland Formula is used for fluid resuscitation after TBSA is estimated.

Correct Answer is C
Explanation
A. Ignoring an arterial line alarm is more serious than causing temporary discomfort.
B. Ignoring alarms contributes to alarm fatigue but does not justify the action or improve safety.
C. Ignoring an arterial line alarm can lead to delayed recognition of critical changes in blood pressure or arterial waveform, potentially resulting in serious injury or death due to inadequate monitoring and intervention.
D. Ignoring alarms does not improve patient outcomes; it significantly increases risk.
Correct Answer is A
Explanation
A. The Allen test assesses collateral circulation to the hand by evaluating blood flow through the ulnar artery before cannulating the radial artery for an arterial line, ensuring adequate circulation.
B. Blood pressure assessment is important but does not specifically evaluate collateral circulation at the insertion site.
C. Monitoring heart rate and rhythm is vital for overall cardiovascular status but unrelated to local circulation for arterial line placement.
D. Oxygen saturation reflects respiratory function, not the adequacy of circulation at the insertion site.
