JVD, increased BP, crackles, Dyspnea, cough, SOB, increased R, cardiac arrest
Notify MD, slow infusion, O2, diuretics and other meds as ordered by MD, keep warm, elevate HOB |
|
|
Electrolyte imbalances (K+, NA+, Cl)
|
replace as ordered
|
|
|
Air Embolism

hypotension, cyanosis, weak rapid P, increased intracranial pressures, loss of consciousness
Clamp off IV, notify MD, place pt on left side and lower head, O2, monitor VS |
|
|

|
2 licensed personnel must check and sign
Y-tubing watch for fever, chills, rash, SOB Stop blood, infuse NS with new tubing, notify MD, send urine sample and blood sample to lab STAT |

|
|
ADH or vasopressin
|
causes kidneys to become more permeable to water, reabsorbs water, increases blood volume, decreases osmolality, decreased circulating volume, decreased blood pressure.
|
|
|
Renin and angiotensin
|
decreased serum or decreased plasma volume cause the cells in the glomerulus to secrete renin, converts to angiotensin 1 in the liver, then travels to lungs, converted to angiotensin 2, a powerful vasoconstrictor, travels to adrenal glands on top of kidneys and stimulates the production of aldosterone
|
|
|
atrial natriuretic peptide - AND or ANP (BNP)
|
cardiac hormone released by atria - opposes renin-angiotensin-aldosterone - increases glomerular filtration which increases urinary excretion of sodium and water
decreases ADH release by posterior pitutitary, reduces vascular resistance by causing vasodilation |
|
|
water intoxication
|
confusion
|
|
|
Hypernatremia
|
causes: increased water loss, decreased water intake, decreased sodium excretion
|
S/S: dry mucous membranes, loss of skin turgor, intense thirst, decreased urine output with increased specific gravity
|
|
Hyponatremia
|
causes: inadequate sodium intake, increased sodium loss through diuretics, sweating, wound drainage, kidney failure, excessive intake of water
|
S/S: mental confusion, altered LOC, anxiety, rapid pulse
