Conn syndrome (primary hyperaldosteronism) is excessive aldosterone production independent of the renin-angiotensin system, most commonly from a unilateral aldosterone-producing adenoma (35%) or bilateral adrenal hyperplasia (60%). Aldosterone acts on the mineralocorticoid receptor in the principal cells of the collecting duct, upregulating ENaC (epithelial sodium channel) and Na+/K+-ATPase, causing sodium reabsorption with potassium and hydrogen ion secretion. This produces: hypertension (volume expansion from sodium retention), hypokalemia (potassium wasting), and metabolic alkalosis (hydrogen ion secretion). The elevated aldosterone suppresses renin (via negative feedback from volume expansion), creating the characteristic LOW renin, HIGH aldosterone pattern. Primary hyperaldosteronism is far more common than previously recognized, affecting 5-10% of all hypertensive patients and up to 20% of those with resistant hypertension.

Topic overview

Conn Syndrome (Primary Hyperaldosteronism): historical NP/APRN lesson restored from legacy corpus (us-np-whnp).

Clinical reasoning

For Conn Syndrome (Primary Hyperaldosteronism), connect the assessment cue to the immediate risk before selecting an action for NP. Start with stability, ABCs, neurologic change, medication risk, infection risk, and scope of practice. Then decide whether the safest next step is assess, intervene, escalate, teach, or evaluate response.

Patient safety implications

A missed priority in Conn Syndrome (Primary Hyperaldosteronism) can delay recognition of deterioration or allow preventable harm to continue. Protect the client first by verifying abnormal cues, using ordered precautions, escalating unstable findings, and reassessing after intervention.

Example application

In a Conn Syndrome (Primary Hyperaldosteronism) item, explain the first cue you noticed, the complication it predicts, the nursing action within scope, and the finding that proves the response worked.
