B. Blood pressure assessment is important but does not specifically evaluate collateral circulation at the insertion site.

Correct Answer is B
Explanation
Parkland formula: 4 mL × body weight (kg) × % TBSA = total fluid for 24 hours
Calculation: 4 × 80 × 45 = 14,400 mL in 24 hours
Half of this fluid (14,400 ÷ 2) = 7,200 mL should be administered in the first 8 hours.
The remaining half is given over the next 16 hours.
Correct Answer is B
Explanation
A. Femoral access actually has a higher risk of infection compared to sites like the subclavian or internal jugular.
B. The femoral site is often considered the least desired due to a higher risk of infection and complications such as thrombosis. It is typically used only when other sites are not available.
C. The subclavian or internal jugular sites are usually preferred over the femoral site.
D. Although the femoral site is easy to access, its risks often outweigh this advantage.
