Which term describes a patient whose condition may deteriorate?

• A. Unstable
• B. Stable
• C. Potentially unstable
• D. Critical

Answer: (C)

The idea is to recognize that a patient’s condition can change quickly, so you assess not just how they are right now but how likely they are to get worse. A patient described as potentially unstable is not currently decompensating, but there is a real risk of deterioration, so you monitor closely, reassess frequently, and prepare for escalation in transport and care. This term signals a need for vigilance and readiness to intervene as the situation evolves, which is different from someone who is unstable (already decompensating) or stable (not showing signs of decline) or critical (life-threatening and requiring urgent action regardless of trajectory). For example, a patient with severe abdominal trauma who currently has stable vitals but a mechanism for rapid bleeding would be managed as potentially unstable: watchful observation, frequent reassessment, and readiness to intervene as signs change.
