Why should you check vital signs in patients with drug and alcohol misuse?

• A. To monitor for infection
• B. To monitor heart rate and blood pressure
• C. To check blood sugar only
• D. To assess hydration level

Answer: (B)

In patients with drug and alcohol misuse, vital signs are watched most closely to catch rapid, life-threatening changes in how the body is functioning. Many substances cause immediate effects on the autonomic nervous system that show up as changes in heart rate and blood pressure. By regularly monitoring these two measurements, you can detect overdose or withdrawal complications early and act quickly (for example, adjusting airway support, fluids, or medications). While infection, glucose levels, or hydration status can be relevant in certain situations, the heart rate and blood pressure provide the most direct, actionable snapshot of the patient’s acute cardiovascular and autonomic status in the context of intoxication or withdrawal.
