sess:Serum Potassium and PR Interval
20.Potassium and dig Fact! Hypokalemia can aggravate digoxin car-
diotoxicity, even in the presence of therapeu-
tic levels of digoxin.
21.Most serious adverse effects of digoxin toxicity?Arrhythmias - including heart block - which may be indicated by an abnormal lengthen-

sionCirculatory collapse -> Respiratory Failure -> GI tract and liver failure -> Renal failure -> neurological Dysfunction
23.Mannitol (osmitrol) is admin-
istered to a patient with a head injury to:Raise Serum Osmolality
Produces both osmotic and vasoactive ef-
fects that decrease intercranial hyperten-
sion, likely related to its theologic properties resulting in a shift of water from the cellular to the extracellular spaces.
The subsequent diuretic phase drains water with the medication to be excreted in urine, resulting in a higher serum osmolality.

poxemia includes:Increased PVR
Pulmonary Hypertension
