Questions and Answers
  • 1. 
    Clonidine
    • A. 

      Antihypertensive

    • B. 

      Alpha 2 agonist

    • C. 

      Causes increased NE and therefore decreased HR and decreased BP

  • 2. 
    Metroprolol
    • A. 

      Non-selective beta blocker

    • B. 

      Decreases HR which lowers BP

    • C. 

      Decreases renin release from kidney (helps to decrease blood volume and lower BP)

    • D. 

      Decreased HR means decreased myocardial O2 requirement = reason it's useful in angina pectoris

    • E. 

      Antiarrhythmic

    • F. 

      Antihypertensive

  • 3. 
    Prazosin
    • A. 

      Alpha 1 blocker

    • B. 

      Causes vasoconstriction and the barroreceptors then decrease HR

    • C. 

      Increases renin release to increase blood volume

    • D. 

      Administer in combination with a beta-blocker or a diuretic

  • 4. 
    Minoxidil
    • A. 

      Opens K+ channels to cause hyperpolarization which results in vasodilation

    • B. 

      Barroreceptor tries to increase HR

    • C. 

      Is an antihypertensive

  • 5. 
    Sodium Nitroprusside
    • A. 

      Decreases cGMP in smooth muscle which causes relaxation

    • B. 

      Used in patients with edema

    • C. 

      Is an antihypertensive

  • 6. 
    Verapamil
    • A. 

      Calcium channel blocker

    • B. 

      Causes vasodilation

    • C. 

      Increased HR

    • D. 

      Used to treat angina pectoris

    • E. 

      Antihypertensive and antiarrhythmic

  • 7. 
    Enalapril
    • A. 

      ACE inhibitor

    • B. 

      Vasodilation

    • C. 

      Bradykinin is the cause of vasodilation

    • D. 

      Used in patients with L.ventricular failure and edema

    • E. 

      Antihypertensive

  • 8. 
    Losartan
    • A. 

      ACE inhibitor

    • B. 

      Decreases contraction of smooth muscle

    • C. 

      Used in patients with left ventricular dysfunction and no edema

  • 9. 
    Loop Diuretics
    • A. 

      Cause decreased water absorption by inhibiting an ion cotransporter in the loop of Henle

    • B. 

      Used for pulmonary edema and severe hypertension

    • C. 

      Can be taken in combination with a sympatholitic and a vasodilator

  • 10. 
    Thiazides
    • A. 

      Increase NaCl transport in the distal convoluted tubule

    • B. 

      Used in patients with mild heart failure and edema

    • C. 

      Useful in angina pectoris

  • 11. 
    Digoxin
    • A. 

      Inhibit Na+/K+ ATPase which increases Na+in the cell

    • B. 

      Decreases intracellular Ca2+

    • C. 

      Causes decreased SNS activity - decreases SNS barroreceptor response (won't get the vasodilation of blood vessels to compensate for increases HR)

    • D. 

      Quinidine helps clear digoxin faster to avoid toxicity

  • 12. 
    Nitroglycerin
    • A. 

      Causes increased cGMP

    • B. 

      Causes vasodilation

    • C. 

      Used as an antiarrhythmic

    • D. 

      Should be administered with sildenafil

  • 13. 
    Furosemide is a more potent diuretic then thiazides
    • A. 

      True

    • B. 

      False

  • 14.
