Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) Correct Answers A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known...

Nitroprusside purpose - Answer- decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action - Answer- contractility Dopamine at a low-end dose "renal dose" - Answer- 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose - Answer- 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose - Answer- greater than 10mcg/kg/min vasoconstriction and increases BP Dopamine and Levophed inf...

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...
