Quiz 3 Flashcards
Particulate Antacids
increase gastric volume, but does not change pH
NOT USEFUL PRE-OP
Examples of particulate antacids
aluminum, magnesium, calcium combos
Nonparticulate (clear) antacids
increase gastric volume but makes it less acidic
Examples of nonparticulate antacids
sodium citrate, bicitra, polycitra

ABX for ortho surgery
Ancef
Where is staph aureus found?
skin, eye
What do thiazides do and where do they work?
inhibit Na and Cl reabsorption; cortical ascending loop and first part of distal tubule
What to loop diuretics do and where do they work?
inhibit Na and Cl reabsorption; medullary ascending limbs of loops of Henle
What do osmotic diuretics do and where do they work?
reduce H20 reabsorption by reducing osmotic gradient; medullary loop of Henle, proximal tubules and cortical collecting ducts
What do aldosterone antagonists do and where do they work?
block action of aldosterone (inhibit Na Cl absorption and K secretion); cortical collecting ducts
What do K sparing diuretics do and where do they work?
inhibit Na, Cl, HCO3 reabsorption and K secretion; distal convoluted tubules
What to CA inhibitors do and where do they work?
inhibit reabsorption of HCO3 ions; proximal tubules
What do dopamine receptor agonists do and where do they work?
stimulate dopamine 1 receptors; renal tubules
Dermatological side effects of steroids
thinning, cushingoid appearance, alopecia, acne, hirsutism, striae, hypertrichosis
