The rate of health complications for patients on intravenous (IV) therapy at a Kalemic Hospital was higher than usual. Government inspectors found that the typical IV solutions used at Kalemic had somewhat high concentrations of sodium and potassium, which could raise patients' blood pressure and tax their kidneys. The government inspectors mandated lowering the sodium and potassium in these IV preparations, threatening a costly government fine. Accordingly, doctors at Kalemic Hospital lowered the sodium and potassium levels in the IV solutions to the correct levels, but patients on IV therapy there continued to have a high rate of health complications.

Which of the following, if true, most helps to explain why acting on the government inspectors' recommendations failed to achieve its goal?
(A) When sodium and potassium levels in the blood fall below their baseline level, it can damage cells throughout the body by reverse osmosis.
(B) Kalemic Hospital recently implemented a new computerized diagnostic system to monitor patients’ health statistics and reveal underlying patterns.
(C) Patients receiving intravenous medications regularly are, on average, more at risk than other hospitalized patients.
(D) A high proportion of patients at Kalemic Hospital are older, and older patients are more vulnerable to infections that can accompany IVs.
(E) When high blood pressure is sustained over the course of years, it compromises several important organ systems.
