A patient, age 37, sustained partial- and full-thickness burns to 26% of the body surface area. When would the greatest fluid loss resulting from the burns occur?
Within 12 hours after burn trauma
48 to 72 hours after burn trauma
24 to 36 hours after burn trauma
36 to 48 hours after burn trauma
The Correct Answer is B
A. Within 12 hours after burn trauma: Fluid loss is significant initially but peaks later.
B. 48 to 72 hours after burn trauma: The greatest fluid loss typically occurs within the first 48 to 72 hours as capillary permeability is at its highest and fluid resuscitation needs are greatest.
C. 24 to 36 hours after burn trauma: Fluid loss is still considerable but not at its peak; the peak is generally observed a bit later.
D. 36 to 48 hours after burn trauma: Fluid loss continues to be high, but the peak is generally reached a little later than this timeframe.

C. Kyphosis: Kyphosis, or excessive curvature of the thoracic spine, can compress the thoracic cavity and reduce lung expansion, which impacts effective air exchange in COPD patients.
D. Arthritis: Arthritis affects joint function but does not have a direct impact on the skeletal changes that alter lung function like kyphosis does.
