Question

1. a 30 - year - old male who ingested an unknown substance begins to vomit. you should: a. collect the vomitus and bring it to the hospital. b. apply a bag - mask device. c. analyze the vomitus and try to identify the poison. d. suction his oropharynx for no longer than 30 seconds.

Explanation:

When a person has ingested an unknown substance and is vomiting, collecting the vomitus can help medical - staff at the hospital identify the substance and provide appropriate treatment. Applying a bag - mask device is not the first step as it's mainly for ventilation and not relevant to the immediate situation of vomiting. Analyzing the vomitus on - site is not practical for non - medical professionals. Suctioning the oropharynx for too long can cause harm and is not the first priority compared to collecting the vomitus for hospital analysis.

Answer:

A. collect the vomitus and bring it to the hospital.
