单选题
A client hospitalized with pneumonia has thick, tenacious secretions. To help liquefy these secretions, the nurse should A. turn the client every 2 hours. B. elevate the head of the bed 30 degrees. C. encourage increased fluid intake. D. maintain a cool room temperature.
【正确答案】
C
【答案解析】Increasing the client's intake of oral or IV fluids helps liquefy thick, tenacious secretions and ensures adequate hydration. Turning the client every 2 hours would decrease pooling of secretions but wouldn't liquefy them. Elevating the head of the bed would reduce pressure on the diaphragm and ease breathing but wouldn't liquefy secretions. Maintaining a cool room temperature would increase the client's comfort but wouldn't liquefy secretions.
