QUESTIONS ANSWERS ACCURATE
A+
◉ Spironolactone (Aldactone).
Answer: Potassium Sparing Diuretic used for Edema
Acts on distal renal tubes to promote sodium and water excretion and
potassium retention.
Adverse Reactions: severe hyperkalemia, thrombocytopenia
◉ Hydrochlorothiazide (Microzide).
Answer: Potassium Wasting Thiazide Diuretic used for increasing urine
output and edema
Action is on the renal distule tubes, promoting Na, K, and water
excretion and decreasing preload and cardiac output; also decreases
edema; acts on arterioles and causes vasodilation, thus decreasing blood
pressure
Adverse Reactions: orthostatic hypotension, hyponatremia,
hypokalemia, hypercalcemia
, ◉ Mannitol (Osmitrol).
Answer: Potassium Wasting Osmotic Diuretic used for IOP ICP and
edema
Increases osmolality (concentration) and sodium reabsoprtion in the
proximal tubue and Loop of Henle.
Adverse Reactions: pulmonary edema, tachycardia from rapid shift of
fluids
Mannitol can crystallize so it must be warmed to dissolve crystals before
administration
◉ Prazosin (Minipress).
Answer: Potassium Wasting Alpha Adrenergic Blocker used to control
hypertension
Dilates peripheral blood vessels by blocking alpha adrenergic receptors.
Adverse Effects: orthostatic hypotension, palpitation, tachycardia
◉ Nifedipine (Procardia).
Answer: Calcium Channel Blocker used for hypertension and angina
