Correct answer: C — Right lateral decubitus with the bleeding lung dependent
Explanation lettering: D = shown as A · A = shown as B · B = shown as C · E = shown as D · C = shown as E
B is correct because placing the bleeding lung down limits contamination of the unaffected lung. C and A place the good lung dependent. D permits bilateral flooding. E may aid expectoration in minor bleeding but does not protect the contralateral lung in life-threatening hemorrhage.
