The symptoms of severe obstruction or choking in adults typically include:
- Inability to breathe or inability to speak
- Weak or ineffective cough
- Cyanosis (bluish skin, particularly around the lips or fingertips)
From your list, the correct options that indicate severe obstruction are:
- Weak and no cough
- Little or no breath
- Breathing but may also be wheezing
Note: "Breathing but may also be wheezing" may indicate less severe obstruction, but when combined with the other symptoms, it can contribute to the overall picture. However, the first two options are more indicative of severe obstruction.
