Baseline data are compared with current assessment to determine what?

• A. Baseline data are compared with current assessment to determine changes.
• B. Baseline data are used to schedule follow-up visits.
• C. Baseline data are irrelevant after treatment begins.
• D. Baseline data determine the medication brand.

Answer: (A)

Baseline data give you a starting point to compare against what you observe now. By looking at how current measurements—vital signs, labs, symptoms—have changed from that starting point, you can see how the patient is responding to therapy. This helps you determine whether there is improvement, worsening, or new problems such as adverse effects, so you can adjust the plan accordingly. Baseline data remain a reference for ongoing monitoring, rather than something that fixes a schedule or dictates the medication brand.
