    it prevents stimulating "fight or flight" responses of the body thereby inhibiting gluconeogenesis
  14. What is the patient education for beta blockers?
    take with food to increase absorption; may increase skin sensitivity to sunlight
  15. What is the mechanism for diuretics?
    cause kidneys to remove more sodium and water from the body and relaxes the blood vessel wall resulting in lower blood pressure
  16. What class of drug is triamterene/HCTZ? What is/are the brand name(s) for it?

    fluid retention (edema) in people with: congestive heart failure, cirrhosis of the lever, nephrotic syndrome
  18. What makes triamterene different from other diuretics?
    K+ sparing, prevents body from absorbing too much salt, keeps potassium levels from getting too low, used to keep K+ in body
  19. What class of drug is hydrochlorothiazide? What is its brand name?
    diuretic; HydroDIURIL
