Antihypertensives

  1. three classes of drugs that are antihypertensives
    (memory trick: A-B-C)

    ACE inhibitors

    Beta Blockers

    Calcium Channel blockers
  2. MOA of ACE Inhibitors and effect
    block conversionof angiotensin 1 to 2 AND aldosterone is blocked

    causes vasodilation  AND dec. in Na and water retention
  3. MOA of beta blockers and effect
    block beta receptors in heart --> dec. HR and dec. force of contraction
  4. MOA of CCB and effect
    block Ca influx into beta receptors --> dec. force of heart contraction and HR
  5. patient teaching for antihypertensives (A-B-C drugs) (4)
    do not stop abruptly

    do not double dose if one is missed

    change position slowly -- may cause orthostatic hypotension

    take caution in hot environments -- may aggrevate low BP
  6. nursing implications for beta blockers (3)
    evaluate BP before giving -- hold if systolic less than 90

    monitor pt with diabietes-- tachy (sign of hypoglycemia) may be masked

    instruct pt to report weakness, dizziness or fainting
  7. side effects of ACE inhibitors (3)
    postural hypotension

    hyperkalemia

    non-productive cough
  8. patient teaching with ACE inhibitors (3)
    rise slowly from lying or sitting

    notify MD if cough develops

    avoid K supplements
  9. nursing considerations with ACE inhibitors (2)
    asses for hx of renal impairment -- contraindicated

    admin on empty stomach
  10. SE of CCB(4)
    edema of extremities

    constipation

    DYSRHYTHMIAS

    HA
  11. patient teaching with CCB (3)
    postural hypotension possible

    avoid grapefruit

    fiber and fluids can help constipation
