The Naranjo Adverse Drug Reaction (ADR) Probability Scale is specifically designed to assess the likelihood that a drug caused an adverse drug reaction. This scale provides a systematic way to evaluate the evidence for a causal relationship between drug exposure and adverse effects by taking into account key factors such as the temporal relationship between drug administration and the onset of the reaction, the presence of other causes for the reaction, and the patient's previous history with the drug.

By using this tool, healthcare professionals can make informed decisions regarding medication safety, helping to identify whether an ADR is likely due to the drug in question rather than other factors. This methodical approach allows for a more accurate evaluation of drug safety and can contribute to better patient care by identifying when a medication should be continued, modified, or discontinued based on its adverse effects.

The other options, while related to medication management, do not pertain to the primary function of the Naranjo Scale. Evaluating medication costs, classifying patient adherence, and documenting medication profiles are distinct assessments that fall outside the scope of assessing ADR causality, making option B the correct focus for the Naranjo ADR Probability Scale.
