59) ANSWER

B) Orthopnea caused by recumbent position

Explanation

Orthopnea is shortness of breath caused by the movement of fluid back into the vasculature when the client lies down. He may have beginning signs of congestive heart failure and should be checked. Sleep apnea may cause orthopnea but not edema; angina doesn't necessarily cause edema either but should be accompanied by chest pain. Recall the definition of orthopnea (difficulty breathing at night when lying flat) to select the correct response.
