How is it Tx
How fast should a deficiency be corrected
Osmotic demyelination syndrome
ASx: water restriction
Moderate: IV NS, Loops
Sev: 50mL 3% NS
10mEq or less over 24hrs
189
What defines HyperNa
How does it present
How is it Tx
What happens if Tx is too fast
Serum Na >145
Poor tugor
Dry skin
Flat veing
IV D5W
Cerebral edema
Pontine herniation
190
What Na lab result indicates Diabetes Insipidus
What are the two possible locations of the issue
What consistent lab result indicates DI
Low urine Na
High serum Na
Polyuria
Neurogenic/central- deficient ADH from posterior pituitary
Nephrogenic- kidneys don't respond to vasopressin or d/t lithium/renal dz
Urine osmolality <250 despite hyperNa
191
What is the 3 step approach to Acid-Base D/o
What causes respiratory acidosis
What causes respiratory alkalosis
1st: ph (7.35-7.45)
2nd: PCO2 (35-45)
3rd: HCO3 (20-26)
Lungs fail to excrete CO2
Excessive CO2 loss
192
What is the next step if metabolic acidosis is encountered
What causes a high anion gap
What causes a low anion gap
Anion Gap- Na - (Cl+BiCarb)= 10-16
Excess H+ ions >16; MUDPILES:
Methanol Uremia DKA Paraldehyde Infection LAcidosis Ethylene glycol Salicylates
<16Loss of BiCarb- diarrhea
193
What causes metabolic alkalosis
Saying to remember average normal valued for acid-base numbers
Loss of H+L vomit, bulemia, OD of antacids
Additional bicard- hyperalimentation therapy
24/7 40/40
BiCarb/pH CO2/acid
