Hypertension (HTN) is a sustained elevation in systemic arterial blood pressure classified by the ACC/AHA 2017 guidelines into stages: Normal (<120/<80 mmHg), Elevated (120-129/<80), Stage 1 (130-139 or 80-89), and Stage 2 (≥140 or ≥90). The pathophysiology involves increased cardiac output, elevated systemic vascular resistance (SVR), or both. Key mechanisms include: RAAS overactivation (angiotensin II causes vasoconstriction and aldosterone-mediated sodium/water retention), sympathetic nervous system overactivity (increased norepinephrine → vasoconstriction and increased HR/contractility), endothelial dysfunction (reduced nitric oxide bioavailability → impaired vasodilation), and renal sodium handling defects (pressure natriuresis curve shifted rightward). Target organ damage from sustained HTN includes: left ventricular hypertrophy (pressure overload → concentric remodeling → diastolic then systolic dysfunction), nephrosclerosis (arteriolar thickening → progressive CKD → proteinuria), retinopathy (arteriolar narrowing → AV nicking → hemorrhages → papilledema), and cerebrovascular disease (lipohyalinosis → lacunar infarcts, atherosclerosis → large vessel stroke, aneurysm formation). Management strategy: Elevated BP → lifestyle modification alone. Stage 1 → lifestyle + pharmacotherapy if 10-year ASCVD risk ≥10% or compelling indication (DM, CKD, HF, post-MI). Stage 2 → lifestyle + pharmacotherapy (consider two-drug initial therapy if...

Topic overview

Hypertension: All Stages & Guidelines: historical NP/APRN lesson restored from legacy corpus (us-np-pmhnp).

Clinical reasoning

For Hypertension: All Stages & Guidelines, 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 Hypertension: All Stages & Guidelines 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 Hypertension: All Stages & Guidelines item, explain the first cue you noticed, the complication it predicts, the nursing action within scope, and the finding that proves the response worked.
