When assessing a client with Cushing syndrome, what cardiovascular sign should the nurse anticipate?

In Cushing syndrome, one of the hallmark features is an increased production of cortisol, which has significant effects on various body systems, including the cardiovascular system. The correct anticipation of hypertension in clients with Cushing syndrome is due to the excess cortisol leading to increased blood volume and vasoconstriction. This elevated blood pressure can be attributed to several factors, including sodium retention and the stimulation of the renin-angiotensin-aldosterone system (RAAS), which promotes further fluid retention and increases vascular resistance.

In contrast to hypertension, bradycardia, hypotension, and irregular heartbeat would not typically be expected in Cushing syndrome. Bradycardia is characterized by a slower than normal heart rate, which would not align with the heightened stress response seen in Cushing syndrome. Hypotension is a condition where blood pressure is lower than normal, which is inconsistent with the fluid-retention and increased vascular resistance observed in this disorder. An irregular heartbeat may occur in various cardiovascular conditions but is not a primary feature associated directly with excessive cortisol levels. Thus, the expectation of hypertension is supported by the pathophysiological changes that occur in Cushing syndrome.
