Card Set Information
Man on loops and CHF and paralytic ileus , what do you next?
Paralytic ileus is one the indication for prompt parenteral potassium replacement
Diuretic induced hypoK , and is common in CHF
Someone with hypoNA and seizures , how do you treat the hypona?
aggressively . i..e 3 % Sodium Chloride
pts with hypoalbinemia will have what kind of Ca level?
Calcium homeostasis in blood is how?
1. Albumin bound Ca+ ( 45 % )
2. Ionized Ca+ (40%)
3. Ca+ cound to inorganic and organic anions (15%)
for every 1 gram decrease in albumin , serum CA decreases by how much?
Symptoms of HypoCa
Chvosteks sign, trousseaus sign, hyperpigmentation, seizures, muscular weakness,
Pt undegoes major abdominal surgery and post-op noted to have hyperactive deep tendon reflexes , which electrolyte is affected?
HypoCa+ can occur during or immediately after surgery , especially in pts undergoing major surgery and requiring transfusions.
what is the leading cause of hypophosphatemia in hospitallized patients?
Continuous glucose infusion
How does hypophosphatemia cause muscle weakness?
1. Imparis ATP
2. also a/w wirh 2,3 diphosphoglycerate --> causes a left shift of the oxyhemoglobin curve , so less o2 gets to tissue
Euvolemic hypoosmolar hypona+ can be due to ? what do you do next?
3. Adrenal insufficiency
- if hypona is mild --> correct underlying issues
- Mode hypoNa+ + SIADH --> water restriction
Sympotomatic HypoNa+--> hypertonic saline
Pt with Hyperosmolar hyperglycemic state (HHS) , management?
1. give fluids
2. than give insulin
DO NOT manage the hyperK+
manifestations of hyperK?
2. ECG abnormalities
ECG abnormality in Hyper K+? and how do you treat it ?
1. peaked T waves
2. prolongated PR and QRS
3. disappearing p waves
: B-agnostic or a combo of glucose and insulin to reduced K levels .. ( i,e calcium gluconate )
treatment of alcoholic ketoacidosis?
UV DEX with Ns and thimaine ....insulin not really needed.
alcoholic ketoacidosis is characterized by:
1. anion gap acidosis,
2.increased osmolal gap,
3.ketonemia or ketonuria and
4. variable blood glucose levels.
Patients with HYPONA+ due to SIADH have ?
1. low plasma osmolality
2. increased urine osmolality
3. and a high urinary sodium concentration
common causes of hepatic encephalopathy?
1. GI bleeding
5. Sedatives or tranquilizers
6. Metobolic alkolosis
7. Infectious ( spontaneous bacterial peritonitis )
