答案: A · To make sputum thinner and easier to cough up
为什么是这个答案
Mucolytics reduce sputum viscosity, which can make expectoration easier and may reduce exacerbations in some people with COPD. They are not bronchodilators or antibiotics. Cough suppressants are generally avoided in productive cough.

8.内外科护理:心血管与呼吸
答案: C · Disconnect and hand-ventilate with 100% oxygen while calling for help
为什么是这个答案
