When ordering or performing patient monitoring functions, what is true according to drug therapy management?

Ordering or performing patient monitoring functions is an essential aspect of drug therapy management, as it directly relates to the effective and safe use of medications for patients. It is often necessary to ensure that therapeutic goals are met and to identify any potential adverse effects early on. By monitoring a patient's response to therapy, adjustments can be made to optimize the effectiveness of the treatment regimen. The phrase "it may be necessary" accurately reflects that while it is not mandated for every situation, there are many circumstances in which patient monitoring is crucial to patient care and outcomes.

In clinical practice, pharmacists often take active roles in patient monitoring functions, which may involve assessing the efficacy of a medication, reviewing laboratory results, or tracking disease progression. This essential practice is part of their responsibilities to ensure that patients achieve desired health outcomes while minimizing risks associated with drug therapy. Thus, recognizing that monitoring may be necessary signifies an understanding of the pharmacist's integral role in the healthcare team, rather than relegating all such responsibilities exclusively to physicians or considering them optional for pharmacists.
