Learning Outcome
Students will gain an understanding of
hypertension, its disease process and
management, and will apply that
understanding to planned patient care.
Learning Objectives
By the end of this module students will
• Compare and Contrast prehypertension, stage
  I and stage II parameters according to JNC 7
  Guidelines
• Differential between essential and secondary
  hypertension
• Describe effects of uncontrolled hypertension
  on body organs
Learning Objectives
• Name a minimum of four causes of secondary
  hypertension
• Define the term "silent killer“
• Create a nursing care plan for a hypertensive
  patient using the nursing process and
  following the provided rubric
Outline
• JNC guidelines for prehypertension and stage I
  & II Hypertension
• Types of hypertension
• Risk factors
• Organ damage
• Treatment
Introduction
Introduction
• Nearly 60 million Americans, or 1 in 4 adults,
  have high blood pressure
• High blood pressure contributes to the deaths
  of almost 30 individuals every hour of every
  day
• An additional 45 million adults, or 22% of the
  population, have prehypertension
• Many individuals don’t even know they have
  hypertension
                       the JNC 7 report. JAMA. 2003;289:2560-72.
Manifestations of Hypertension
• Usually no symptoms other than elevated
  blood pressure
• Symptoms are related to organ damage and
  are seen late and are very serious
Parameters According to JNC 7
• Seventh Report of the Joint National
  Committee on Prevention, Detection,
  Evaluation, and Treatment of High Blood
  Pressure (JNC 7)

JNC 7 Parameters




Key: SBP = systolic blood pressure DBP = diastolic blood pressure
Types of Hypertension
• Essential 90% - 95%
  – Cause is unknown
• Secondary 5% - 10%
  – High blood pressure that
    is caused by another
    medical condition or
    medication
Secondary Hypertension Causes
• Chronic kidney disease
• Disorders of the adrenal gland
  (pheochromocytoma or Cushing syndrome)
• Pregnancy (preeclampsia)
• Medications such as birth control pills, diet pills,
  some cold medications, and migraine
  medications
• Narrowed artery that supplies blood to the
  kidney (renal artery stenosis)
• Hyperparathyroidism
Risk Factors
• Factors that cannot be changed
  –Family history of high blood pressure
  –Family history of premature CVD
  –Diabetes
  –Race (African American)
Lifestyle Risk Factors
•   Weight (body mass index > 30 kg/m2)
•   Stress
•   Sedentary lifestyle
•   Diet
•   Smoking
•   Alcohol (more than one drink per day for women
    and more than two drinks per day for men)
• Birth control pills
