Reassessment is performed to determine all of the following, EXCEPT:

• A. the patient's response to your treatment.
• B. the nature of any newly identified problems.
• C. whether or not the patient is deteriorating.
• D. the reason why the patient called EMS.

Answer: (D)

Reassessment is about checking how the patient is doing after you’ve begun treatment and seeing how they’re responding. It focuses on current status and trends: is the patient’s condition improving, staying the same, or getting worse? Are there any new problems, and does the patient still need the same level of care or a change in treatment or transport decisions? This helps you adjust care in real time and prevents deterioration.

The reason the patient called EMS is established during the initial scene assessment and history taking. It’s background information that informs your plan, but reassessment concentrates on the patient’s present condition and response to treatment, not on reaffirming why EMS was contacted. For example, after giving oxygen and relieving chest tightness, reassessment would look at vital signs, level of consciousness, work of breathing, and pain relief to determine if the patient is improving or needs further intervention.
