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.
Correct Answer is B
Explanation
A. The use of a pressure bag is standard practice, not situation-dependent.
B. True. The flush solution for an arterial line must be infused using a pressure bag (typically at 300 mmHg) to maintain patency of the line and prevent blood backflow or clot formation.
C. Without a pressure bag, the arterial line is at risk of occlusion and inaccurate pressure readings.
D. This is a standard nursing practice and does not require a specific doctor’s order
