The graphs below display the systolic blood pressure of four clients for 30 days before and 30 days after starting a new medication on March 1. What can be inferred from the information displayed in the graphs?

This statement is not necessarily true as the graphs do not show a clear increase in variability in blood pressure after the introduction of the new medication. Variability would imply a greater fluctuation or range in blood pressure readings, which is not consistently evident across all clients.

While it is true that some clients' systolic blood pressure decreased over time, attributing this to the natural passage of time rather than the introduction of the new medication is not supported by the information in the graphs. The decrease coincides with the introduction of the medication, suggesting a possible causal link.

This statement is incorrect because the graphs do not show a decrease in systolic blood pressure for every client. Some clients' blood pressure remained relatively stable or even increased after starting the new medication. Therefore, the claim that each client's blood pressure decreased over time is not supported by the data.
