A 50-year-old patient with 60% total body surface area (TBSA) burn and a weight of 70 kg requires fluid resuscitation. Using the Parkland formula, how much total fluid volume should be administered in the first 24 hours?
16,800 mL
18,000 mL
14,000 mL
12,600 mL
The Correct Answer is A
A. 16,800 mL is correct based on the formula.
The Parkland formula is:
4 mL × body weight (kg) × %TBSA burned
= 4 × 70 × 60
= 16,800 mL total fluid in 24 hours
B. 18,000 mL overestimates the requirement.
C. 14,000 mL underestimates the fluid needed.
D. 12,600 mL is too low for a 60% TBSA burn in a 70 kg patient.

Correct Answer is C
Explanation
A. Pulmonary artery diastolic pressure (PADP) reflects left ventricular end-diastolic pressure and can be used as an indicator of left heart function and fluid status.
B. Not applicable as a standalone choice.
C. Both PADP and pulmonary artery wedge pressure (PAWP) are sensitive and commonly used hemodynamic measurements to assess cardiac function and intravascular volume.
D. Pulmonary artery wedge pressure (PAWP) is a direct reflection of left atrial pressure and is considered a sensitive indicator of left ventricular preload and fluid volume status.
Correct Answer is A
Explanation
A. An arterial line allows continuous, real-time monitoring of blood pressure, providing accurate and immediate data important for critically ill patients.
B. The presence of an arterial line may actually increase infection risk if not properly cared for.
C. Arterial lines do not improve oxygenation directly; they monitor blood pressure.
D. Pulmonary wedge pressure is measured via a pulmonary artery catheter, not an arterial line.
