A nurse assessing a client with Cushing's syndrome should report which observation immediately?

• A. Pitting edema of the legs
• B. An irregular apical pulse
• C. Dry mucous membranes
• D. Frequent urination

Answer: (B)

The urgent issue in Cushing's syndrome is the risk of cardiovascular instability from electrolyte disturbances. Excess cortisol can have mineralocorticoid-like effects, promoting sodium and water retention and potassium loss. Low potassium can disrupt cardiac conduction and lead to an arrhythmia, which shows up as an irregular apical pulse. That change signals a potentially life-threatening rhythm disturbance and requires immediate assessment and intervention. Edema from fluid retention can occur in Cushing's, but it is not as immediate a red flag as an abnormal pulse. Dry mucous membranes suggest dehydration, which is less likely the primary concern here, and frequent urination points more toward hyperglycemia than an immediate cardiac threat. So, reporting an irregular apical pulse right away addresses the most dangerous potential complication.
