here's 2 & 3
--advance apologies everyone, for not felt like coming online...i just lost my Biji (grandm) :'-(and so past few days had been rollercoaster..

A.] HYPOVOLEMIC SHOCK: inadequate tissue perfusioon & circulatory dysfunction due reduced intravascular bllood volume (requires early recognition & prompt treatment to improve prognosis)

causes:
--ascites
--blood & fluid loss, fluid shifts
--burns
--hemothorax
--peritonitis

--pathophysiological changes:
a. tachycardia
b. cerebral hypoxia -->tachypnea
c. vasoconstriction -->cool, pale, clammy skin ; reduced urine uoutput
d. reduced SV & CO -->narrow plulse pressure
d. hypotension, shallow respirations, cyanosis
e. metabolic acidosis


A.] SEPTIC SHOCK: metabolic changes & circulatory collapse as response to infection (develops in 25% of patients with gram-negative bbacteria)

--causes:
gram-negative bacteria
gram-positive bacteria

--pathophysiological changes:
a. infection -->chills and fever
b. tachycardia and bounding pulse
c. cerebral hypoxia -->tachypnea
d. vasoconstriction -->reduced urine output
e. vasodilation -->warm, dry skin
f. hypotension, hypoxia, cyanosis
g. acid-base / electrolyte imbalance -->absent reflexes
h. respiratory center depression -->slow, shallow or Cheyne-Stokes respiration


good luck i wish frm my heart you all best blessings for ur exam..
