What is a critical piece of information to gather about a patient smelling of alcohol?

• A. Last known meal
• B. Allergies
• C. Substance use history
• D. Recent medical history

Answer: (C)

Gathering a comprehensive substance use history is essential when encountering a patient who smells of alcohol. This information can provide valuable insights into the patient's current condition and potential underlying issues. Understanding a patient's substance use can help assess their level of intoxication, identify possible withdrawal symptoms, and reveal any prior incidents that may be relevant to their treatment. It also assists responders in making informed decisions about the patient's care and necessary interventions.

While knowing the last known meal, allergies, and recent medical history can be important in an overall assessment, the specific context of alcohol consumption makes substance use history the most pertinent information. This detail helps in understanding how alcohol might be affecting the patient's system and guides the appropriate response to their condition.
