A patient is admitted to the intensive care unit with a diagnosis of septicemia. In addition to relieving agitation and anxiety, what is a rationale for using benzodiazepines in the treatment of a critically ill patient?
A) Increased diffusion and perfusion
B) Decreased cardiac workload
C) Increased level of consciousness
D) Decreased blood pH
B
Feedback:
Antianxiety and sedative–hypnotic drugs are often useful in critically ill patients to relieve stress, anxiety, and agitation. Their calming effects decrease cardiac workload (e.g., heart rate, blood pressure, force of myocardial contraction, myocardial oxygen consumption) and respiratory effort. They do not decrease blood pH, increase diffusion and perfusion, or increase LOC.
